Top 10 Diesel Engine Manufacturers in the world - Blog

Introduction to Diesel Engine

A diesel engine is an internal - combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so - called compression - ignition engine (CI engine). Rudolf Diesel, a German inventor, patented the diesel engine in 1892. Diesel engines are known for their high efficiency, durability, and ability to generate high torque at low speeds. They are widely used in various applications, including transportation (trucks, buses, ships), power generation, construction equipment, and agricultural machinery.
