Top Three Common Problems for Car Engine  Once morning your engine doesn't start... What's wrong? if you know how engine works, you can understand the basic things that keep an engine from working. their is Three fundamentals reasons for that problem : lack of compression , a bad fuel mixor or lack of spark. Beyond that, thousands of minor reasons that can create problems, but these are the "mostly happens reasons" , here is a quick rundown on how these problems Lack of compression - If the charge of air and fuel cannot be compressed properly, the combustion process will not work like it should. Lack of compression might occur for these reasons: - Your piston rings are worn (allowing air/fuel to leak past the piston during compression). There is a hole in the cylinder. - The intake or exhaust valves are not sealing properly, again allowing a leak during compression - The most common "hole" in a cylinder occurs where the top of the cylinder (h...

    in the previous sections we had discuss : - Classification of Internal Combustion Engines and Engine Components (Course) - Internal Combustion Engines Components 2 (Course)   3- Internal Combustion Engines cooling and lubrication system (Course)   In This  section we will discuss : -Describe the crankcase ventilation systems, function, operation, inspection, and service. -Describe the induction systems, functions, operation, inspection, and service -Describe engine-starting devices/systems for diesel and gas engines.     SECTION 4 Objective 8 Describe the crankcase ventilation systems, function, operation, inspection, and service. CRANKCASE VENTILATION Function of the Crankcase Ventilation System The crankcase ventilation system keeps the engine crankcase purged of blowby and water vapour. BIowby is burned and unburned gases that escape past the rings into the crankcase. The water comes from condensatio...
