Top 10 diesel engine Suppliers in the world - Blog

Introduction to Diesel Engines

Diesel engines are internal combustion engines that operate on the Diesel cycle. Rudolf Diesel patented the first Diesel engine in 1892. These engines are known for their high efficiency, durability, and ability to generate high torque. They are widely used in various applications, including transportation (trucks, buses, trains, ships), power generation, construction equipment, and agricultural machinery. Diesel engines work by compressing air in the combustion chamber to a high pressure, which raises the air temperature. Then, fuel is injected into the hot, compressed air, causing it to ignite spontaneously. This process is different from gasoline engines, which use a spark plug to ignite the air - fuel mixture.
