9.1.4 产生汽油机长期以稀混合气运行故障信息记录的原因近年,从发达国家进口的乘用车一般都具备较高级的排放控制设备及对这些设备实施故障诊断的功能。这类乘用车能够对汽油机长期以稀或者浓混合气运行的故障设置故障信息记录(有时并无该故障)。有一些发动机的故障症状就是由这种故障引起的。
9.1.4 Reasons for generating fault information records of long-term lean mixture operation in gasoline engines In recent years, passenger cars imported from developed countries generally have higher-level emission control devices and fault diagnosis functions for these devices. This type of passenger car can record faults (sometimes without this fault) on faults of long-term or rich-gas engines. Some of the engine failure symptoms are caused by this failure.
