Introduction to Diesel Engines
Diesel engines are a type of internal - combustion engine that operate on the Diesel cycle. Rudolf Diesel invented this engine in 1892. Unlike gasoline engines, which use a spark plug to ignite the fuel - air mixture, diesel engines rely on the heat of compressed air to ignite the diesel fuel that is injected into the combustion chamber. This makes diesel engines more fuel - efficient, as they can achieve higher compression ratios. Diesel engines are widely used in various applications, including heavy - duty trucks, buses, ships, construction equipment, and power generation. They are known for their durability, high torque output, and long - term reliability.
