Introduction to Diesel Engines
A diesel engine is an internal - combustion engine that uses the heat of compression to initiate ignition and burn the fuel that has been injected into the combustion chamber. It was invented by Rudolf Diesel in 1892. Diesel engines are known for their high efficiency, durability, and torque output. They are widely used in various applications, including heavy - duty trucks, buses, construction machinery, agricultural equipment, marine vessels, and power generation. The high compression ratio of diesel engines allows for better fuel economy compared to gasoline engines, and they can operate on a variety of fuels, including diesel fuel, biodiesel, and other alternative fuels.
