Top 10 diesel engine Suppliers in the world - Blog

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 fuel - air mixture, diesel engines rely on the heat generated by compressing air in the combustion chamber to ignite the diesel fuel that is injected into it.

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. Their ability to produce a large amount of torque at low speeds makes them ideal for applications that require pulling or lifting heavy loads.
