2.12 电磁喷油器驱动电路故障信息电磁喷油器驱动电路本身有故障监测功能。电磁喷油器控制电路只提供高、低两种数值的电平,但必须按规定的时刻提供。如果电磁喷油器驱动电路监测到在其电路中有一个错误的电平,且该错误的电平持续了一定时间(例如5 s)以上,则ECU设置故障信息记录。2.13 怠速转速偏差超出规定范围如果汽油机实际怠速转速比计算得出的怠速转速低或高出某一数值(例如 180 r/min)以上,且该实
2.12 electromagnetic injector drive circuit fault information electromagnetic injector drive circuit itself has fault monitoring. Electromagnetic injector control circuit provides only high and low two levels of value, but must be provided at the specified time. The ECU sets up a fault message record if the electromagnetic injector drive circuit detects that there is an erroneous level in its circuit and the error level persists for a period of time (eg 5 s). 2.13 Deviation of idle speed deviation outside the specified range If the actual idle speed of the gasoline engine is lower or higher than the calculated idle speed by a certain value (eg 180 r / min)
