摘　　要：通过对发动机电子控制单元(ECU)喷油脉冲信号、车速信号的采集、经滤波整形,送入ATmega128单片机。ATmega128单片机根据喷油脉宽与燃油消耗量的函数关系以及车速信号间接的算出发动机的百公里油耗和每小时耗油量,并将这些数据利用LCD显示设备进行显示。通过这些数据的显示可以实现指示驾驶员按照经济节油的方式驾驶从而达到节能减排的目的。同时监测发动机工作状况,使驾驶员提前发现故障。对发动机工作状况的监测,也可以延长一些达到更换周期而不需更换的零件的使用时间,达到降低相关零件的更换频率,减少资源浪费,保护环境的作用。The fuel injection pulse signal and the vehicle speed signal of engine electronic control unit（ECU） were collected,filtered and shaped into ATmega128.According to the injection pulse width and fuel consumption of the vehicle speed signal function,ATmega128 figures out the engine oil consumption per hundred kilometers per hour and fuel consumption,and uses these data for LCD display.The data display can tell the driver in accordance with economic saving way of driving so as to achieve energy saving purposes.Meanwhile,they can help monitor the working condition of the engine,so that the driver can find the fault in advance.Through the monitoring on the engine work status,the use time of some parts can be extended to reduce the replacement frequency and the waste of resources and to protect the environment.
