diesel engine

A diesel engine is a type of engine that runs on a fuel called diesel. This is different than the fuel used to power cars and trucks that run on gasoline. Diesel engines work by using a process called compression ignition. This means that they use air pressure to create heat and then ignite the fuel. This is different than engines that use spark plugs and gasoline which need a spark to ignite the fuel. The diesel engine is usually used in bigger vehicles because it is more efficient and powerful than gasoline engines. For example, trains and ships often use diesel engines because it gives them the power they need to travel long distances. An interesting fact about diesel engines is that they were invented by a man named Rudolf Diesel. He was a German engineer and his invention revolutionized the transportation industry.
