摘要
汽车发动机功率检测设备结构复杂,操作繁琐,在一般的维修厂很难推广使用。针对这一问题,研制了一种操作简单,成本低的可移动式汽车发动机功率测量仪。采用点火脉冲电流来测量发动机的转速,通过测量驱动轮制动力获得转矩,进而计算发动机输出功率。实验结果表明,该测量仪结构设计合理,能方便地测量发动机功率,误差满足测量精度要求。
Power detection equipment of the automobile engine is complex in structure and difficult in operation.Then it is difficult to promote average maintenance shop.Therefore,a portable type of automobile engine power measuring instrument with simple operation,low cost is developed.The engine speed is measured by using the current impulse in the ignition coil,the torque is obtained through measuring braking force of driving wheels,and the power output of automobile engine is calculated.The experiment results indicate that this apparatus can easily inspect the power output of automobile engine benefit by its rational structural design.The errors can satisfy the requirements of measuring accuracy.
