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…
