Consider the following:

Cylinder

Spark Plug

Piston

Which of the above is / are used in Diesel engine?

Question

Cylinder: Diesel engines, like gasoline engines, also have cylinders. These are the main chambers where the combustion process occurs. In a diesel engine, air is compressed inside the cylinder, and the high temperature resulting from compression ignites the diesel fuel, causing it to burn and drive the piston down.
Spark Plug: Unlike gasoline engines, diesel engines do not have spark plugs. In a gasoline engine, spark plugs are used to ignite the air-fuel mixture. In contrast, diesel engines rely on high compression ratios to generate the heat needed for spontaneous ignition when the fuel is injected into the compressed air.
Piston: Pistons are a crucial component in both diesel and gasoline engines. In a diesel engine, the piston plays a similar role as in a gasoline engine. It moves up and down within the cylinder, and its motion is driven by the force generated from the combustion of diesel fuel. The downward movement of the piston is what creates mechanical energy that ultimately drives the vehicle\'s wheels.
