Abstract: G12V190ZLDT gas engine adopts the latest control concept and control device as well as the closed-loop electric control system with the ability for lean combustion. It is characterized for high intelligence, low heat consumption, good reliability, low emission and long service life. With the power output ranging from 550kW to 800kW, it can meet the demand for mobile and fixed power generation and compressors. The technical indexes reached the world’s advanced level. It filled the blank in China’s closed-loop electric control gas engine. Innovations have been made in a series of key technologies, such as air fuel ratio closed-loop control, lean combustion, and highenergy intelligent digital ignition system. G12V190ZLDT gas engine mainly uses natural gas and is also suitable for low pressure resources like bio-gas and coal gas. It has a high adaptability for variable concentration gas tools.
