Engine type is a term used to describe the type of engine used in a vehicle. The most common types of engines are turbo, STEAM, hemi, JET, veight, DIESEL, and fourcylinder. Turbo engines use exhaust gases to increase power output, while STEAM engines use STEAM to power the vehicle. Hemi engines are characterized by their hemispherical combustion chambers, which allow for more efficient combustion. JET engines use a turbine to compress air and fuel, creating thrust. Veight engines are eight-cylinder engines that provide more power than smaller engines. DIESEL engines use compression ignition to power the vehicle, and fourcylinder engines are four-cylinder engines that are typically found in smaller vehicles.
