Combustion engines are a well-known technology used in automobiles, trucks, construction equipment, marine propulsion, and backup power applications. Combustion engines employ the expansion of hot gases to push a piston within a cylinder, converting the linear movement of the piston into the rotating movement of a crankshaft to generate power. Reciprocating internal combustion (IC) engines are characterized by the type of combustion: spark-ignited (SI) or compression-ignited (CI), also known as diesel. Through a continuous investment in research and development JINAN gas and diesel engines remain market leaders in the area of power generation. The engines are highly efficient at the conversion of the energy within gas into useful electrical power.
