Series 190 inner mixing gas engine is developed by our company to meet the requirement of market. The whole engine is optimized by amending the shortages of the first gas engine generation. The power performance, fuel economy and reliability of this gas engine are improved a lot by adopting inner mixing mode, increasing compression ratio and boost ratio, enhancing swirl rat io, realizing lean -burnt by controlling air fuel ratio, using high-energy ignition, and etc.

This engine series is mainly used in generating by single engine or several engines forming a power station. It also can be used as power of compressor, oil t ransfer pump, water in jection pump, and etc.
