| Abstract: | In order to develop CA6SH-NE3 CNG engine, which will meet the GB 17691-2005 emission standard, the problems to impact on emission is studied. Determine the approach of theoretical A/F matching three-way catalyst（TWC）, that is use electronic multi-point injection controlling A/F, improve combustion chamber and air-intake distributing system, and use TWC to clean exhaust pollutants. The engine construction was optimized, and performance tests were carried out. The test results show that the engine has better power performance, fuel economy, and achieve development targets |
