- Which of the following is not a true statement about diesel engines?a. The operation and main components of a diesel engine are comparable to those of a gasoline engine. Diesel and gasoline engines are available as four- stroke combustion cycle engines. Diesel engines rely on glow plugs instead of spark plugs to initiate ignition. The compression ratio of diesel engines is typically three times that of a gasoline engine.arrow_forwardWhich of the following are not typically found in the block of a modern engine? a. Pistons b.
