缸号

对6240柴油机的实例分析表明，不仅可以利用0.5谐次扭振相位角准确判断出内燃机拉缸缸号，还可利用其幅值反映拉缸故障程度。

And the case analysis on 6240 type diesel engine suggested that not only the phase angle of 0.5 order torsional vibration can be used to diagnose the cylinder-scoring number , but also the amplitude can reflect the fault degree .

在瞬时转速曲线和角加速度曲线上提取几个特征参数，再用灰色关联度分析方法和极值缸号一致性检查法对特征参数的优良性进行评价。

Several characteristic parameters are extracted from the angular velocity curve and the acceleration curve of crankshaft instantaneous rotation , and the quality of them is evaluated by use of the gray relation analysis method and the method for inspecting the consistency of the extremum cylinder number .

位置正时是电控单元正常工作的基础，电控单元工作时只有确定当前的工作缸号及当前曲轴的位置才能在正确的时刻把燃油喷入到正确的气缸。

Position synchronization is the foundation of the work of the electronic control unit normally . ECU must determine the current working number of cylinder and the current location of crankshaft to make sure that it is at the right time to make fuel inject into the cylinder correctly .
