| Abstract: | The multi-point sequential injection engine fueled with compressed natural gas(CNG) was developed based on a diesel engine.The combustion system and induction system of diesel engine were improved.The high energy ignition system,gas-supplied system and electronic control unit were designed.The three unique catalytic converter was added.The closed loop control method of air-fuel ratio was adoped.The test results show that the power performance and the emission of natural gas engine reaches the requirement of design. |
