    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...
