一辆重庆长安汽车在正常行驶中,发动机慢慢熄火,且不能再发动。检查电路确诊无故障后,断定为油路故障:汽油泵至油箱间有阻塞或漏气(用手油泵泵不出油)。拆下汽油进油管,用气筒向油箱打气,证实进油管至油箱畅通,且不漏气。但装复后仍起动不着。进一步详细检查发现:油箱底面与进气管连接处因箱底变形引起油管部分阻塞(未全部堵死,用气筒打气能畅通)。因此,在发动时,自油箱流出的油量极少,故发动不着。拆下油箱,修复凹凸处,发动机恢复正常工作。
A Changan Automobile in Chongqing normal driving, the engine slowly flameout, and can not be started. Check the circuit diagnosed trouble-free, concluded that the oil fault: gas pump to the tank obstruction or leak (hand pump not oil). Remove the gasoline into the tubing, pump gas to the tank cheer, confirmed that the oil into the tank smooth, and does not leak. However, still unable to start after loading complex. Further examination revealed that the connection between the bottom of the fuel tank and the intake pipe caused partial blockage of the tubing due to deformation of the bottom of the fuel tank. Therefore, at the time of launch, the amount of oil flowing out of the tank was extremely small and therefore could not be activated. Remove the fuel tank, repair bump, the engine back to normal work.
