Market Definition
A diesel power engine is an internal combustion engine that operates on the principle of compression ignition. It uses diesel fuel, a type of petroleum-derived liquid fuel, as its primary source of energy. In a diesel engine, air is compressed within the combustion chamber to a high temperature, causing the diesel fuel to ignite spontaneously upon injection into the chamber. This combustion process generates mechanical energy, which is harnessed to drive various applications such as vehicles, generators, construction equipment, marine vessels, and industrial machinery. Diesel engines are renowned for their fuel efficiency, durability, and high torque output, making them widely used across diverse industries for both stationary and mobile power generation.
