151. Diesel engine
A diesel engine is an internal-combustion engine that normally ignites fuel through the heat created by highly compressed air rather than by using spark plugs. For this reason, it is also known as a compression-ignition engine.
Diesel engines are commonly used in passenger cars, trucks, buses and machinery because they can provide strong low-speed torque and efficient fuel use. Modern diesel engines use emissions-control systems such as particulate filters and selective catalytic reduction to reduce harmful exhaust emissions.

How does a diesel engine work?
A diesel engine compresses air inside the cylinder until it becomes very hot. Diesel fuel is then injected into the compressed air and ignites because of the high temperature.

What emissions can a diesel engine produce?
Diesel engines can produce pollutants including nitrogen oxides and particulate matter or soot. Modern vehicles use systems such as diesel particulate filters and other emissions-control technologies to reduce these pollutants.
