Introduction to Diesel Engines
Diesel engines are a type of internal - combustion engine that operate on the Diesel cycle. Rudolf Diesel invented the diesel engine in 1892. Unlike gasoline engines, which use a spark plug to ignite the fuel - air mixture, diesel engines rely on the heat generated by compressing air in the combustion chamber to ignite the diesel fuel. This makes diesel engines more fuel - efficient and generally capable of producing more torque, which is why they are widely used in heavy - duty applications such as trucks, buses, ships, and industrial machinery.
