turbo charger , how does it works?

The efficiency of IC engines and pollution generated from it depends largely on the turbo charger. Turbo charger is driven by exhaust gases leaving the engine and this power is used to compress the gas to the engine intake. Turbo charger usually has two main sections, the turbine and compressor.


A typical turbine consists of a collection of fins and the axis of one, in which the fins are placed. The shaft is supported by some kind of bearings. The fins making fluid energy (which is taking the pressure head and kinetic head) and turns the shaft. This shaft drives the compressor turns. Turbines can be one of the combinations of the two following types:

* Impulse Turbine

Pelton wheel is an example of this type of turbine. Using the nozzle, fluid velocity increases as the pressure remains constant, so the change in momentum of fluid particles is produced, hence the force is applied to the fins. This type of turbine is an application of Newton's second law.

* Reactive turbine

reactive turbine is a practical application of Newton's third law. Unlike the turbine impulsive, reactive fluid from the turbine exits the turbine and thus applies the reactive force of the turbine.


The compressor reduces the volume of gas consumption by increasing pressure on it. The compressor is identical to the pump. The pump works with liquids and gas compressor. All compressors can be classified broadly into two sections, namely, the positive displacement type and the type of dynamics.

Diaphragm compressors, rotary screw compressors etc., are examples of such displacement compressor and centrifugal compressor etc. are examples of dynamic compressor.

Waste gate

As the amount of exhaust gas will increase, increase the speed of the turbine and therefore more and more amount of air that is taken for compression and this in turn increases the intake pressure of the system. Now, if the inlet pressure increases, which further increases the speed of the gas turbine exhaust. So by this process turbocharger speed increases continuously. waste gate is a mechanical system, which passes through a certain amount of gas turbine exhaust in order to limit the speed of the turbocharger.

Should You Repaired Or Replaced your car's engine?

Having to replace an air pump is inconvenient, but tolerable. Replacing a muffler or alternator is more expensive and therefore more frustrating. But it's still bearable. engine of your car, on the other hand, is one of the few sets (transmission is the other) where a mistake can crush your budget.

Your engine will not last forever, of course. Depending on how hard it is to drive and the number of miles you put on it, you can expect it to last 100,000 miles and twice that amount. If you keep your car long enough, eventually develop serious problems.

Then we will explore the decision to fix the whole in comparison with what it replaced. We will explain why discovering the root causes of a problem is a fundamental part in making this decision. Finally, we describe the main differences between a new engine and a rebuilt unit.

Deciding whether to repair the Assembly

Suppose your car is eight or nine years and I have traveled very hard during those years. As a result, the engine finally failed. The first question is whether you should keep your car, or retire and buy a new one. Much depends on your age, value and condition.

For example, if your car has a market value of $ 2,500, spending more than $ 1,000 for your engine repaired (or replaced) seem to make sense. But if your car has retained its value and other major components (eg transmission) are kept in good shape, spend the money could be worthwhile.

Suppose you have decided to keep your car. Now the question is whether the engine should be repaired or replaced failing. Your decision will largely depend on your state and the number of miles on it.

For example, if the assembly is 130. 000 kilometers, a history of valve or piston misfire problems and a chronic, the repair will be costly. The mechanic might need to carry out extensive work on the cylinders. You may need to align the engine block and replace the valves.

Also, with an overhaul, the entire assembly must be dismantled. Individual pieces are removed, so the mechanic can check for defects, cracks or other structural problems. The components are in good condition that have been cleaned. Those in poor condition will be replaced. Once the pieces have been either cleaned or replaced, the assembly is put back together.

It is painstaking work. A review of the engine requires a huge amount of time and effort. This is why a lot of mechanics strongly suggest that the engine replaced.

The differences between the new and rebuilt engines

You can buy an assembly used in a junkyard, but it can be dangerous. There is no way to be sure if there are problems hidden from view, particularly with engines that have a lot of miles. Even if you find a set of use with low miles and a limited warranty, it will generally be a less than ideal. The price will be consistent with a remanufactured unit, which have been placed at the OEM level. At that time, it is better to invest in the second.

A new engine is exactly as it sounds. Each individual piece is new. The valves, pistons, engine blocks, cranks and other parts have never been used.

A rebuilt unit is almost as good (and much less expensive). Remans assemblies that are used have been dismantled, examined closely and carefully cleaned. Most of the parts that wear over time (eg, timing belt, gaskets, etc.) are replaced. Then, the assembly is rebuilt and tested to ensure that it meets OEM standards.

Which option is better? If your budget is limited, a remanufactured engine that has been raised with OEM specifications is an ideal solution. It will get your car on the road without the high cost associated with a new assembly.

Amazing Geothermal Energy Facts

One of the least known of renewable geothermal energy for electricity is created using the heat content of the magma underground. The magma heats the rocks and sometimes travel directly through the sources of water below the surface of the heating up. Extract and run water through tubes around another set of pipes containing a liquid with low boiling point. This causes the liquid becomes a vapor that can be used to run steam turbines. Here are some interesting facts about geothermal energy for its construction.

No fuel is consumed in the process of creating geothermal electricity and is therefore free of emissions.

Multiple types of existing power plants include binary cycle power plants, the hot dry rock geothermal energy, plants, dry steam, flash steam plants, heat source and geothermal heat pump. The most common binary cycle. High ability to generate energy from the source (hot water) is constantly supplied. The heat extracted from the ground is extremely small, but potentially could be used until after millions of years. Power plants do not occupy much space as the main components are pumping groundwater. The fluids used with low boiling points are corrosive and therefore the maintenance and take care when handling. Carbon dioxide and sulfur may be emitted as a byproduct of geothermal electricity due to appear in the water. Philippines Iceland and make maximum use of geothermal energy and create around 25% of its electricity. They are by far the leaders in this area of energy production.

There is much to learn about if you fully understand this issue but I hope this has taught some of the basics and the most interesting things to learn. Some things to look at more would be different types of existing water reservoirs that are tapped, and some specific information on methods for enabling the generation of geothermal electricity.

The Importance of Servicing Your HVAC System

It's easy to assume that the HVAC system is running correctly. You may think that since you do not notice any immediate problem with your heating or air conditioning your air conditioner is working properly. This, however, can not be the case. Do not leave for annual inspection and service of HVAC. Without the routine visit by a service technician air conditioning, your furnace or air conditioner may not work as well and begin to operate inefficiently. The problems that otherwise could have been captured will be allowed to grow and cause damage to your air conditioning system, shortening its life.

The most important reason why you should take steps to ensure that your heating and air conditioning service is security. The natural gas and oil HVAC systems burning fossil fuels, which can produce harmful byproducts like carbon monoxide. You certainly do not want to risk your health or your family from breathing poisonous gas, so be sure to have a professional HVAC technician to service your unit's annual maintenance. Furthermore, without an annual inspection, your heating system may have a higher risk of triggering a fire. After undergoing the heating routine service significantly reduced the likelihood of a catastrophic accident occur. In most cases, an annual inspection service HVAC contractor to identify potential problems before they happen. They will be able to remedy the problem, or advise on the best course of action to ensure the safety of your family.

Another advantage of having a licensed technician perform annual service on your HVAC system is adequate to maintain efficiency. When your heating and air conditioning are well tuned to run at peak efficiency. This means less energy consumption and reduce utility bills. The annual service costs HVAC is much less than the amount of savings you will receive in energy bills when the unit is optimized to operate at peak efficiency.

It is important for the HVAC technician to check for dust accumulation and debris inside the furnace and air conditioning, and inspect the unit to ensure the parties are in good working condition and are installed correctly. Cleaning the air conditioning system will allow you to continue to run smoothly without being hindered by the soot and dirt that eventually accumulates. The HVAC contractor will also ensure the vents are clear and all gases are able to escape through vents or chimneys.

Taking the measure of your HVAC system inspected annually not only saves you money on your energy bills, but you will have peace of mind knowing that your family and home are safe from toxic gases. In addition, the small expense of having a professional service of your unit will save you money when compared to the cost of buying a new unit.

CNC Programming General Information

CNC Programming is one of the most effective ways that people are using today in order to cut metal and do other processes in manufacturing. Many hobbyists are using CNC programming to produce woodworking, metals and foam objects. CNC has created a way for many people to manufacture or fabricate parts quickly and effortlessly.
CNC stands for computer numerical control and is basically the use of a computer to do certain types of operations. This is a process that can be applied to lathe, router, foam cutters and laser machines; it can also be applied to mini versions of these types of machines.
There are basically two types of categories that CNC program will fall into point to point positioning or continuous path positioning. Usually a computer can execute both types of programming depending on the sophistication of the software program being used. This means that the operator must understand both processes in order to run the machine.
Here is a simple explanation of these two categories:
Point to point positioning - this category is mostly used when drilling, boring, punching or tapping is needed. This is a process used to position from one point to another when the machine process is being done. In other words, it works from the X to the Y position or to as many positions as it is instructed and keeps going until the process is finished.
Continuous path positioning - this category is generally used when a lathe or milling machine is being used and is used for contouring (contouring is another name for this category). This means that the cutting tool moves in a continuous motion from one point to another until the piece is completed. This means that the operator has to be able to program the machine so that it continues on several axes at a time and simultaneously.
Continuous path positioning also uses a series of processes called interpolation which is the way in which the machine is programmed to go. Interpolation can be helical, parabolic, cubic, circular and more. The basic function of this interpolation is to keep the programmed information stored and to monitor and direct the axes in how it should go.
Before any of the programming can be done there is a manuscript that is used which is the basic drawing of what is to be made. This must be studied to make sure that the operator understands the intricacies of the drawing so they can translate the information into the computer software they are using.
This means that the operator must be skilled enough to understand how the paper drawing will translate to the computer, and then be able to program this information into the computer so that the machine will perform the cuts or the processes accordingly.
When you think about this process, it is a good idea to think about what you would do if you were producing the work manually because anything you would do manually, you will depend on the machine to do automatically. By understanding both processes the individual will be more successful.

Repairing Your Own Machine Components

Many industrial concerns have workshops of their own. For the
repair of worn shafts, the lathe machine is excellent. Keyway
slots can be machined by using a milling machine, while a
shaping machine can do machining of large flat areas. A
drilling machine does drilling of holes.
A skilled Maintenance Engineer should know how to use all these
machines in order to make his own repairs in a safe manner. Very
often he has to supervise machinists. The information below
should be useful for that purpose.
Lathe Machine
The lathe machine uses a single-point-cutting tool for a variety
of turning, facing, and drilling jobs. Excess metal is removed
by rotating the work piece over the fixed cutting tool to form
straight or tapered cylindrical shapes, grooves, shoulders and
screw threads. It can also be used for facing flat surfaces on
the ends of cylindrical parts.
The work piece is clamped onto a horizontal rotating shaft by a
3-jaw or 4-jaw chuck. The latter chuck can be used to cut
off-centered cylinders. The rotating horizontal spindle to which
the chuck is attached is usually driven at speeds that can be
The cutting tool is fixed onto a tool rest and manipulated by
hand. It can also be power driven on straight paths parallel or
perpendicular to the work axis. This is useful for screw cutting.
Internal turning known as boring results in the enlargement of
an already existing hole. The holes are more accurate in
roundness, concentricity, and parallelism than drilled holes. A
hole is bored with a single-point-cutting tool that feeds along
the inside of the work piece.
Shaping Machine
The shaping machine is used to machine flat surfaces, grooves,
shoulders, T-slots, and angular surfaces with single-point tools.
The cutting tool on the shaper oscillates, cutting on the forward
stroke, with the work piece feeding automatically toward the tool
during each return stroke.
Drilling Machine
The drilling machine is used to cut holes in metal with a twist
drill. By changing the cutting tool, they can be used to do
reaming, boring, counter boring, countersinking, and threading.
Milling Machine
The milling machine uses a rotating cutting tool to cut flat
surfaces, grooves, and shoulders, inclined surfaces, dovetails,
and T-slots. Cutters of many shapes are changed to cut different
Cutting Tools
Metal-cutting tools are classified as single point or multiple
point. The lathe and shaping machine use single point cutting tool
while the milling and drilling machines use multiple-point-cutting
Metal is cut either by moving the work piece like in the lathe or
by moving the tool like in the shaping machine, drilling or
milling machine. Clearance angles must be provided to prevent the
tool surface below the cutting edge from rubbing against the work
piece. Rake angles are often provided on cutting tools to cause a
wedging action in the formation of chips and to reduce friction and
Tool Materials
In order to remove chips from a work piece, a cutting tool must be
harder than the work piece and must maintain a cutting edge at the
temperature produced by the friction of the cutting action.
Carbon Steel
Carbon steel tools even though comparatively inexpensive tend to
lose cutting ability at temperatures around 400 degree F (205
degree C).
High-Speed Steel
High-speed steel, containing 18 percent tungsten, 4 percent chromium,
1 percent vanadium, and only 0.5 to 0.8 percent carbon, permits the
operation of tools twice or three times the speeds allowable with
carbon steel
Cast Alloys
Cast-alloy cutting-tool materials containing cobalt, chromium, and
tungsten are effective in cutting cast iron and retaining their
cutting ability even when red hot.
Cemented Tungsten Carbide
The hardness of Tungsten Carbide approaches that of a diamond.
Tungsten carbide tools can be operated at cutting speeds many times
higher than those used with high-speed steel.
Ceramic, or oxide, tool tips consist primarily of fine aluminum oxide
grains, which are bonded together. These are very hard.
Cutting fluids
An overheated tool can become blunt and soft very fast. Therefore
very often, cooling fluids cools the cutting points of the tool. This
serves to lubricate and cool.
Water is an excellent cooling medium, but it corrodes ferrous
materials. Sulfurized mineral oil is one of the most popular coolants
as it can both cool as well as lubricate. The sulfur prevents chips
from the work from melting on to the tip of the tool.

Basics of a Milling Machine

A milling machine is one of the most used shop tools in today's manufacturing world. Without it, hours and hours of manual labor would be required to produce even simple machine parts. Today's manufacturers depend on mills to give them the parts they need quickly, efficiently and at an affordable cost.
This amazing piece of shop equipment is used to shape solid material such as metal, plastic, brass or wood. It is somewhat different than a lathe because finished parts are not cylindrical. A mill uses a high-speed cutting tool that moves over and into material that has been securely placed on the table. A mill can produce a finished part or a vacuum forming mold. Today's mills are not usually designed to cut underneath a top surface. Instead, they more effectively create many separate components which can later be formed into more complex items.
CNC (Computer Numerical Control) technology is primarily used in today's sophisticated machine mills. This method of control uses CAD/CAM technology to program the commands necessary to run the mill smoothly and efficiently. With CNC, there is little need for human intervention in the production process because everything is pre-programmed from start to finish. Items are pre-designed on a 3-D computer screen and then are physically generated through the programmed milling process.
There are two primary types of machine mills - vertical and horizontal. The vertical version's axis is vertically oriented and its cutters are held in the spindle, rotating on the axis. Two types of vertical mills are bedmills and turret mills. In a turret mill, the spindle always remains stationary during cutting but in a bedmill, the table moves perpendicularly to the spindle axis. A horizontal mill has its cutters mounted horizontally rather than vertically. This type of mill is effective when shallow angles are desired in the milling process.
A milling machine is invaluable in any manufacturing shop. While its initial cost may seem high, the overall efficiency and effectiveness of the machine will more than cover any original monetary outlay.

CNC Milling Machine - How it Can Help You

CNC is a system that has end to end component design is highly automated with the use of CAD programs. The programs generate a computer file that is translated to extract the commands that are needed to control a specific machine and then loaded into the CNC machines for production. CNC means Computer Numerical Control and it signifies particularly to the computer control of machine equipment. The principle purpose of CNC milling machines is repeatedly produce complex part in metal as well as other materials with the use of unique coded program.
This particular coded program that is being used by CNC milling machines is written in a notation known as the G-code. It indicates a specific CNC milling duties in alphanumeric format. CNC milling was produced in the year 1940 by MIT servomechanism laboratory. CNC milling can operate the functions of drilling and turning. It can be identified according to the number of axes that they had, it is often labeled as X and Y for horizontal motion and Z for vertical motion. This program has changed the manufacturing industry, such as cutting straight lines in a curve made easy, simple way to create complex 3-D and a lot of machine steps the need human action is way down.
In fabrication process, the use of this machine have been cut down to just a fewer of methods. Nowadays, it is controlled directly from a computer programs that has been manufactured by CAD software. With the use of this software you can develop an outstanding design without using a scratch or drawing works. All industrial tasks are made easier and faster at the same time lessen the production cost of the company.
Before purchasing a CNC milling machine, you need to have a knowledge or experience about its basic and standard machine parts. It is primarily composed of safety shield that is mostly a clear plastic cover that shields the cutting part. Tool bit is a part of the machine that executes the cutting skills. When getting a milling machine you must be sure to examine all of the important parts and if they are all in its proper places because if only one is not intact the machine will surely not work or sometimes will produce an undesirable result. It is also important to check its safety features, keep yourself away from purchasing a CNC milling machine that does not possess an emergency stop button.

Things to Know About a Milling Machine

Choosing a milling machine can be a mind-boggling task. There are so many different types of machine mills that it can take some serious research to find exactly the right one that will get the job done for you. One of the most popular designs is a vertical milling machine because it handles well and is very flexible in the jobs it performs. One drawback is that it tends to be slower than other types of machines.

Machines that do milling work very simply by just cutting solid material (such as metal or plastic) using some type of onboard rotating tool. It also includes an adjustable table for x (side), y (vertical) or z (height) directions. Handles are generally used to steer the table in the desired direction.

This special cutting machine comes with accessories to make the whole milling process even better. A vise is often used to affix the material to the table before it is milled. The operating handles on the machine have digital scales that help in the adjustment of the x, y and z axes. Another helpful accessory is a point master which enables more accurate cutting and processing. In order for the machine to work correctly, the zero point must be completely accurate and this is accomplished by using the point master.

A variety of things can be made with a machine mill (or with a "miller", as it is sometimes called.) An endmill is often utilized in producing complicated items such as fish robots. The individual parts of the fish robots are often cut and made separately on the mill and then assembled together later. This same process is used on many other milled items as well.

A milling machine is one of the most important tools used in today's thriving manufacturing business. It takes solid materials like metals and shapes them into desired items. Machine mills are excellent to use on flat or irregular surfaces that otherwise would be extremely difficult tasks to perform. Not only does they cut items professionally, they also do other things like drilling, boring, planning and slotting. A machine mill is an invaluable piece of manufacturing equipment that would be irreplaceable if it suddenly disappeared from the workshop.

Advantages of a Horizontal Milling Machine

Milling basically come in two different styles: vertical and horizontal. Both have certain advantages. This article will mainly focus on the best features found in a horizontal milling machine.

horizontal machining is highly profitable and produce high quality products. This type of milling machine is designed for do it all with a variety of hard materials. The process is fast and requires minimal configurations along the path. This lowers the cost of labor increasingly often accompany any manufacturing environment. The finishes are higher and the final product comes out as planned. Many horizontal mills are fully automated and require no human intervention to work properly. All programming is done in advance, so that nothing is left to chance. This reduces processing time by 25% because manual work is no longer necessary.

horizontal milling offers advantages such as: machining, performing functions in general as well as other operations such as recording and boring. This is usually done in one operation by a router. This type of grinding also eliminates most of the manual effort required once. Multiple configurations are gone and tools do not need to be changed as often. Furthermore, the parties need not be transferred from one machine to another and from one place to another. The processing delays are minimal because there is to be expected for the next machine because everything is done continuously by a machine.

A horizontal mill works in much the same manner as a vertical milling machine does. However, horizontal mills, support arm over your head and blades which are driven shaft. These two characteristics distinguish them from the vertical models and add a little more detail the actual operation of the machine. horizontal mills have to pay a little more attention to safety and maintenance standards, so that no serious injury has occurred. A horizontal milling cutters used to require ongoing maintenance to ensure they are always sharp. Other important safety precautions to consider are the use of proper teeth cutter and let stand arm in place when tightening or loosening the roundabouts.

PlayStation 3 Wholesaler Industry - News

Want to find a PlayStation 3 wholesaler, to get your hands on the much-awaited console quickly and cheaply? You will need to wade through a swamp of scams and cheats - but rest assured, there are honest merchants out there, and it will be possible to get yourself a PlayStation 3. Just do not expect it to be a simple case of looking up a wholesaler on the internet- you will have to do some work yourself if you want to do it alone.
The easy but unpopular method is to wait. If you can hang on until mid 2007, you will almost certainly be able to get a PlayStation 3 at a lower price, and with a lot less hassle. By March of 2007 there should be about 6 million units in circulation-which should be enough for most of the people who want a PS3.
But suppose you want to get hold of the PlayStation 3 before Christmas? What Playstation 3 wholesaler should you turn to?
For a start, do not think you are going to be able to get one at real wholesale price often, in January 2007. Unless luck comes in your way that is, which is very unrealistic in this kind of business. The price set by Sony- $499 for the basic units, $599 for the premium ones- is lower than the price that the market would set by itself. So the places you might usually look for a cheap deal- online auctions, resellers, wholesale distributors- are out of the question.
Sure, if you have $1000 to spend on a console, go ahead and buy one at eBay - but that is the kind of price you will be seeing the consoles resell for, after the still continued launch as there are many countries that are due up for launch and arrival.
Importing a PlayStation 3 from Japan is another bad idea. People do this with a wide variety of goods - not just consoles but books, DVDs, CDs and other items, and sometimes it can be done easier in your same US state. Not so with the PlayStation 3. Sony has carefully arranged a legal setup for the PlayStation 3, which makes importing the Japanese version into another region, is illegal.
Sony have demonstrated the illegality of importing the Playstation 3 by winning a court case against a man by the name of Lik-Sang, who was involved also in the sell of importing PSPs.
So, you are going to have to stick to the mainstream retailers for now and shop around prices if re-sell is your goal. Look around on the Internet for the best deals - but do not believe anywhere that promises too good to be true cheap prices. Instead, go for bundle deals: outlets selling the PlayStation 3 with free games or accessories included.
That is the way they can offer the PlayStation 3 cheaply, without generally- breaking many of the already pricing agreements Sony has given to many retailers and authorized dealers. So do not go for the Playstation 3 wholesaler anytime soon, you should search for distributors and online hidden wholesalers that specialize in such gaming practice.

Automotive Industry News That Makes a Point

While the average person can not have much interest in news from the automotive industry, a lot of useful information can be obtained. This would include interesting reasoning behind why you can not always find the car you want at a dealership. Many consultants pushing dealers to listen to customers and their needs. Despite this suggestion would work when you look in theory, there are some things that are stopping it from happening.

It is not actually the dealers are dropping the ball most of the time, the car manufacturers themselves. You can not send what has been requested by the dealers, instead of sending the vehicle you want. That leaves the dealers with an inventory that is not what you ask or what their customers want.

This unfortunate circumstance leaves the dealer with the option of using aggressive sales tactics or let the car sit around forever. Those hard to sell cars can continue to sit for a while, but ultimately it will create problems for the dealer, as no customer really want, you can buy. You hope that the vehicle you want or, sometimes opt for another option.

Continued accumulation of these vehicles can leave the dealer with no cars to suit the needs of their clients or want. You definitely want this figure when the head at the local dealer and not see a car you want.

The hard sell their cars still sit around a banana called "brown" because it is too ripe, and the value has been declining as it continues to not get discouraged. At this point, what can a seller actually about this issue?

Giving away free cars, but customers could emotion is something that is not going to happen. Even when they release a lot of money on the price, who hurt themselves as dealers are carried out to make a certain amount of profit. If they do that amount of benefits that could be closed.

Of course the distributors could return to the days when hard sales is being used all the time. However, it will not make a satisfied customer in any way. Many people hated to see a seller to raise them in those days.

You probably had done before - you know the old "let me see the keys" routine. They state they needed to look to value your car for trade-in, however, once the keys were gone he took some serious persuasion might be able to tap your car so you could get out.

It was a process that earned him many people of ill repute in the past. They will wear out over time, until finally I would agree with the sale. Not only do you get a car that they were not sure you wanted to, but may have too much debt.
