Introduction to Diesel Engine
A diesel engine is an internal - combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression. Rudolf Diesel invented the diesel engine in 1892, and since then, it has become an essential power source in various industries. Diesel engines are known for their high efficiency, durability, and torque output. They are widely used in trucks, buses, ships, generators, and construction equipment. The efficiency of a diesel engine comes from its high compression ratio, which allows for more complete combustion of the fuel, resulting in better fuel economy compared to gasoline engines.
