Read the text:

Diesel engines and gasoline engines are quite similar. They are both internai combustion engines designed to convert the Chemical energy available xn fuel into mechanical energy. The major difference between diesel and gasoline is the way these explosions happen. In a gasoline engine, fuel is mixed with air, compressed by pistons and ignited by sparks from spark plugs. In a diesel engine, however, the air is compressed first, and then the fuel is injected. Because air heats up when it is compressed, the fuel ignites.
