发动机起动问题

jellyby · 发表于 2010-9-20 10:27:31

发动机湿起动是不是只供油不点火？手册上讲移动发动机起动手柄至慢车位置后，如果排气温度（EGT）在15秒内不上升，则EEC停止发动机起动。EEC停止燃油流并关掉点火。是不是我们在做正常起动后起动手柄移动到慢车位，过几秒就会点火了？

During a normal engine start, EGT should be increasing within 5 seconds. Abort the engine start If you don't see the increase of EGT in 15 seconds. If you're using auto start then everything is controlled by EEC, but mind you that EEC doesn't not monitor oil pressure during engine start.
