| 摘 要： | 当煤层气的组分发生变化时，煤层气发动机的空燃比也随之发生变化，从而导致发动机运行不稳定，甚至熄火。针对这一问题，研究开发了一套变浓度煤层气发动机电子控制燃气喷射系统，提出了与煤层气发动机相适应的驱动电路，并设计了系统控制软件。

| Abstract: | The air fuel ratio(A/F) of the coal bed gas engine changes with the varing of gas composition.And the engine will run unsteadily accordingly,or even flameout.In order to solve this problem,a new gas injection electronic control system of the engine was designed and the drive circuits suitable for the engine was put forward.Besides,the control software of the system was also designed. |

| Keywords: | coal bed gas engine electronic fuel injection(EFI) air fuel ratio |
