4000 Series (1320-2200KW)

L20V1902LT-2type 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，The rarefied combustion technology uses WOODWARD's E6 control system to accurately control the air-fuel ratio. Reach the high - altitude combustion ratio, achieve 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 cooler to improve cooling efficiency, 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.
