Question

The blow by losses is the phenomenon of leakage of combustion products past the piston and piston rings from the cylinder to the crankcase.

(a) True

(b) False

I got this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Engine Friction in section Engine Friction and Lubrication of IC Engine

Answer 1

The correct answer is:

(a) True

Blowby losses refer to the leakage of combustion products past the piston and piston rings from the cylinder into the crankcase. This phenomenon reduces engine efficiency and can lead to contamination of the crankcase oil, which may affect engine performance and longevity.
