2发动机管理系统的构成EA888系列发动机采用MED17.5发动机管理系统,系统的构成如图16所示。其中,DFM信号是用于检测发电机输出电压的,在发动机负荷过大,电量不足的情况下,用以提高发动机的转速。3 EA888系列发动机维修要点3.1变速器侧密封法兰安装注意事项变速器侧密封法兰(手动变速器)上带有密封圈,在更换时需进行总成更换,并且密封圈的密封唇不允许涂抹油,安装前
2 engine management system structure EA888 series engine MED17.5 engine management system, the system shown in Figure 16. Among them, the DFM signal is used to detect the generator output voltage, in the engine load is too large, insufficient power to improve the engine speed. 3 EA888 Series engine repair points 3.1 Transmission side seal flange installation considerations Transmission side seal flange (manual transmission) with a seal on the replacement of the need for assembly replacement, and the seal lip seal oil is not allowed, Before installation
