in the previous section we had discuss : Classification of Internal Combustion Engines and Engine Components (Course)     that  we had discussed in : -Classification of Internal Combustion Engines -Internal Combustion Engine Components     lets begin our section which we will discuss : -Describe individual pump, distributor, and common rail fuel injection systems for a diesel engine. -Explain the purpose and describe the operation of superchargers and turbochargers - Describe the cooling systems, function operation, inspection, and service.       SECTION 2 Objective 3 Describe individual pump, distributor, and common rail fuel injection systems for a diesel engine. THE FUEL INJECTOR The diesel engine, unlike some gasoline engines, does not use a carburetor to mix the fuel and air nor does it use a spark to ignite the fuel-air mixture. Instead, the diesel uses an injection system to spray the fuel into the engine cylinder. The fuel...

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. Turbine 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...
