What is a diesel engine?

A diesel engine, also known as the compression-ignition engine, is an internal combustion engine. The engine works as it uses the heat of compression to initiate ignition and burns the diesel fuel that has been injected into the combustion chamber.

How diesel engines work?

Diesel engines utilize four-stroke combustion cycle to convert chemical energy available in diesel fuel into mechanical energy. This mechanical power moves the pistons up and down (pistons are designed inside the cylinder). Hence, the crankshafts connected with pistons move up and down accordingly. This motion is known as the linear motion, which helps create the rotary motion in order to turn the wheel of machinery forward.

Diesel engine cycle

For a diesel engine, the cycle in an internal combustion engine consists of induction, compression, combustion and exhaust strokes. The air is first compressed, and then the diesel fuel is injected. Air heats up when it is compressed. Finally, the diesel fuel ignites.
