Introduction to Diesel Engines
Diesel engines are a type of internal combustion engine that operate on the diesel cycle. They were invented by Rudolf Diesel in 1892. Unlike gasoline engines, which use a spark plug to ignite the air - fuel mixture, diesel engines compress the air in the combustion chamber to a high enough temperature that when fuel is injected, it ignites spontaneously.
Diesel engines are known for their high efficiency, durability, and torque. They are widely used in various applications, including heavy - duty trucks, buses, construction equipment, marine vessels, power generators, and agricultural machinery. In China, the diesel engine industry has witnessed significant growth over the years, with many domestic suppliers emerging as global players in terms of technology, quality, and production capacity.
