| Abstract: | In order to meet the needs for the large-scale increase of natural gas engine, natural gas engine combustion system and induction system are optimized. The high-energy electric ignition, gas supply system and electronic control unit are adopted. The three-way catalytic converter reduces the exhaust emission by the method of air-fuel ratio feedback control. Engine of multi-point sequential injection quantity of CNG is developed based on diesel engine. Experiment result shows that the power performance of natural gas engine reaches the index of the design. Exhaust emission meets the needs of national standard. Hence this method is feasible. |
