工作时，主齿轮10直接传动第一付齿轮8和第二付齿轮9。在发动机运转时，主控制器12(ECU)通过发动机上的转速传感器采集发动机的转速，当发动机的转速超出主控制器12(ECU)设定的转速时，主控制器12(ECU)将输出信号并控制电机14转动，并带动主齿轮10转动，主齿轮10带动第一付齿轮8和第二付齿轮9转动，并调节第一、第二节气门片6、7开度的大小，以保证发动机稳定在主控制器12(ECU)设定的转速范围内。
本发明结构紧凑、布局合理、高度集成，集成了ECU、电机、进气温度传感器，高度集成的方案使电喷系统在发动机上使用更加的方便，满足了双缸通用型发动机的节能环保的要求。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明所附的权利要求的保护范围。
工业应用性
