4000 Series (2200KW)
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 the 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 the 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.
Specification of 4000 Series
In 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 Genset, 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.
