| Abstract:Research was carried out on the air-fuel ratio control technology based on one type of high-power marine gas engine. The target air-fuel ratios and the critical points of air-fuel control under different loads were calculated through one dimensional simulation tool. Then bench best was carried out to study and verify the air-fuel ratio control technology applicable for this type of gas engine. The results show that the technology using throttle valve with bypass valve could satisfy the performance requirements of steady-state and dynamic air-fuel ratio control. |
| Key words: high power marine gas engine air-fuel ratio control strategy |
