在采用BOSCH共轨系统的柴油发动机上,故障代码P100E的出现频率较高,为轨压限制阀打开故障,其设置条件为当实际轨压超出设定轨压200 bar(1bar=100kPa),且时间大于2s时,轨压限制阀打开泄压。该故障代码一般不是由轨压限制阀自身故障引起的,而是由于共轨系统的其他部分出现故障,导致发动机短时间或长时间进入失效保护模 On diesel engines with the BOSCH common rail system, the fault code P100E appears at a higher frequency and opens a fault for the rail pressure limiting valve, which is set when the actual rail pressure exceeds the set rail pressure of 200 bar (1 bar = 100 kPa) When the time is greater than 2s, the rail pressure limiting valve opens to relieve pressure. The fault code is generally not caused by the rail pressure limiting valve failure itself, but due to failure of other parts of the common rail system, causing the engine to enter the failure mode a short time or long time
