Spark Plug - Test
如果生成了点火变压器二次回路的诊断代码,可能需要维修火花塞。 失火或气缸冷是火花塞蚀损的另一信号。 使用 Caterpillar 电子技师(ET)监测排气口温度以确定冷气缸的位置。
火花塞的使用寿命受润滑油中沉积物污染及峰值电压的影响。 点火系统的保养间隔也受电压影响。 进气歧管空气压力较高、压缩比较高或正时延迟,都需要高电压。 较高的电压会降低部件如火花塞和变压器的使用寿命。
为帮助预测火花塞的使用寿命,使用 Cat ET 监视次级电压。 该值代表次级电压的百分比。 火花塞间隙随着时间磨损,该值增大。 新火花塞的值为 0%。 该值超过 90% 就可能需要保养。 该值为 100% 时,需要更换火花塞。 在特定现场维持此电压的记录有助于确定火花塞的正确更换间隔。
有关火花塞的检查和更换说明,请参阅操作和保养手册。 有关火花塞的更多信息,请参阅发动机的技术规格手册。
