In a Diesel engine cycle, the stroke that immediately follows the intake stroke is the compression stroke. During the intake stroke, the engine draws in air, which then enters the cylinder. After the intake stroke is complete, the compression stroke begins, where the piston moves upwards to compress the air in the cylinder.

This compression is crucial because it raises the temperature and pressure of the air to a point where the fuel can be injected. Unlike in a gasoline engine that uses a spark to ignite the fuel-air mixture, a Diesel engine relies on the high temperatures achieved through compression to ignite the fuel when it is injected. This process is essential to the operation of the Diesel engine, making the correct identification of the sequence of strokes vital in understanding its mechanics.
