CHEVEND TECHNOLOGIES Interview Questions and Answers

A four-stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crankshaft.

• Intake stroke: The piston moves downward, drawing in a mixture of air and fuel.

• Compression stroke: The piston moves upward, compressing the air-fuel mixture.

• Power stroke: The spark plug ignites the mixture, causing an explosion that drives the piston downward.

• Exhaust stroke: The piston moves upward again, pushing out the exhaust gases.
