According to order No. 17 of the Ministry of Petroleum Industry (82), Jichai started the research and development of high-power turbocharged natural gas engine in 1982.From 1984 to 1988, three prototype tests were carried out in the laboratory and 10,000 hours of industrial tests were carried out in Shengli Oilfield.It passed the national appraisal on October 12, 1988, and the type of the appraisal machine is 600kW/ 1000R /min externally mixed supercharged high-power gas engine.After years of continuous improvement, the products have been serialized and widely used in various oil fields and gas applications, which have brought great economic benefits.

|Recent years, with the improvement and promotion of series H16V genset, The market share of Jichai gas generator sets in the gas power generation market, especially in Shanxi, has been increasing year by year, and the market share of 1000kW low-concentration gas generator sets has reached more than 90%.However, At present, Jichai does not meet the market requirements within the power range of 1000kW~2000kW.It is necessary to develop 190 series gas generator sets covering the power segment of 1000kW~2000kW, so as to maintain the cost advantage over foreign gensets, at the meantime expand the power coverage, continue to improve the competitiveness of 190 series gas generator sets, and maintain the competitive advantage .|
The single power of the long-stroke 20V190 gas engine covers the power segment of 1000kW~2000kW, and the gas type can take into account natural gas, gas and biogas, which has a broad market demand prospect.
L20V1902LT-2 type closed-loop electrically controlled external mixing natural gas machine features:
1.Turbocharger pre-mixing technology, where gas and air are sucked in at the same time in the compressor, to be suitable for low pressure gas,
2.Rarefied combustion technology，WOODWARD's E6 control system is used to control the air-fuel ratio accurately to reach the high - altitude combustion ratio, rarefied combustion
3.The single point injection and air - fuel ratio closed - loop control technology can realize the closed - loop control of air - fuel ratio (in).The engine can adjust the amount of air and natural gas according to the requirements of different working conditions and different speeds, so that the engine can run in the best state.
4.Efficient and reliable design of the intake and exhaust system, the use of advanced high pressure ratio, large flow supercharger, increase the flow area of the intake pipeline, improve the intake efficiency
5.High efficiency, low resistance and plate type oil cooling book are adopted to improve cooling efficiency and increase cooling area of air and lubricating oil.
6.The ignition system with high energy and high reliability is selected to make the combustion of each cylinder of the engine more stable and even.
