Engine

The utility model provides an engine. The engine comprises a camshaft gear; the idle gear is meshed with the cam shaft gear; the fuel pump gear is meshed with the idle gear; and the phase signal panel is coaxially fixed on the fuel pump gear, and the phase signal panel indirectly acquires a steering signal of the cam shaft through the fuel pump gear. According to the utility model, the phase signal panel is coaxially arranged on the fuel pump gear to indirectly acquire the steering signal of the camshaft, so that the wiring harness is more convenient to install and does not interfere with each other. 本实用新型提供一种发动机，包括：凸轮轴齿轮；惰齿轮，所述惰齿轮和凸轮轴齿轮啮合；燃油泵齿轮，所述燃油泵齿轮和惰齿轮啮合；相位信号盘，所述相位信号盘同轴地固定在燃油泵齿轮上，所述相位信号盘通过燃油泵齿轮间接地采集凸轮轴的转向信号。本实用新型通过将相位信号盘同轴地设置在燃油泵齿轮上，间接采集凸轮轴转向信号，使得线束安装更方便、不相互干涉。
