Car Repairman Interview Question:

Do you know what Is Back Compressor In Engines?

Submitted by: Muhammad

Back compression means the compression capability of the engine. An diesel engine can compress at the ratio of 14:1 to as high as 25:1. Thus the higher compression leads to better efficiency of the engine. Thick black smoke is emitted when the engine's compression is reduced which leads to the deformed ead-gasket lead into crankcase.
