一辆装有YC6108发动机的CA1091型卡车在行驶到一段小路时,发动机突然熄火,不能起动。检查发现高压泵静态供油提前角已改变。校正静态供油提前角后起动发动机,发动机工作不正常,且很快又自动熄火。再检查发现静态供油提前角又改变,提前器相对于连接盘的位置也已移动。检查连接盘时,发现传动凸缘盘二个紧固螺栓太长,凸缘盘未被压紧。重新校正
A CA1091 truck fitted with a YC6108 engine suddenly ran out of steam and could not be started while traveling to a lane. Check found that high-pressure pump static oil advance has changed. After calibrating the static fuel supply advance angle, the engine is started, the engine is not working normally, and the engine automatically turns off quickly. Check again and found that the static supply advance angle has changed, advance the position relative to the connection plate has also been moved. Check the drive plate and found that the drive flange plate two bolts too long, the flange plate is not compressed. Recalibrate
