Diesel Mechanic Technician Interview Questions and Answers

There are two main types of diesel engines: two-stroke and four-stroke.

• Two-stroke diesel engines complete the combustion cycle in two strokes of the piston, while four-stroke diesel engines complete it in four strokes.

• Two-stroke engines are typically used in smaller applications like motorcycles and chainsaws, while four-stroke engines are more common in larger vehicles like trucks and buses.

• Four-stroke engines are more fuel-efficient and produce less emissions compared to tw...read more

The stroke of an engine refers to the distance the piston travels from top dead center to bottom dead center.

• The stroke is typically measured in millimeters or inches.

• It determines the engine's displacement and power output.

• Common strokes include 4-stroke and 2-stroke engines.

• For example, a 4-stroke engine has four strokes: intake, compression, power, and exhaust.
