摘　　要：一辆2008年产的迈腾1.8TSI轿车,出现无规律加速无力、有时熄火的故障现象。通过分析该车燃油系统的工作原理并检查控制电路,发现导致该车偶尔熄火的主要原因是燃油滤清器堵塞。由于燃油滤清器堵塞,导致低压油路油压过低,从而使混合气过稀,因此发动机熄火。更换燃油滤清器后故障彻底排除。A Magotan 1.8TSI car made in 2008 is troubled with irregular weak acceleration and occasional stalling. By analyzing operating principle of the car＇s fuel system and examining the control circuit, it is found that main cause of occasional stalling of this car is clogged fuel filter, which leads to excessive low pressure in the low-pressure fuel line, causing over-lean gas mixture, engine thus stalls. The trouble is eliminated completely after the fuel filter is changed.
