机油报警灯
机油报警灯亮起即表示机油存储量和压力值低于标准,如果不尽快停车添加机油,会导致发动机润滑不足,从而产生磨损。
水温报警灯
水温指示灯用来提示发动机内冷却液的温度,有的会以颜色来显示不同的效果,蓝色表示水温过低,红色则表示水温过高,而不亮的情况下表示正常。当水温报警灯显示冷却液温度过高时,驾驶员应立即停车,如果继续行驶会导致发动机高温,从而使得缸体变形。
发动机故障灯
一般在汽车启动自检时会亮起,启动汽车之后会自动熄灭,如果这时发现该指示灯常亮,就表示发动机可能存在故障,应尽快停车检查。
刹车系统故障灯
感叹号加一个圆圈的标志表示刹车系统出现故障,这时驾驶员应先确认手刹是否完全松开,然后检查刹车油液位置是否正常或者刹车片是否过薄。如果此标志常亮,赶紧停车。
车门提示灯
该指示灯点亮表明车门没有全部关闭,此时应立即停车检车车门或者发动机前盖是否完全关严。如果在行驶过程中车门突然打开,随时都有可能发生严重的交通事故。
胎压报警灯
胎压指示灯平时处于熄灭状态,而亮起时就表示轮胎的胎压不足,也可能是轮胎发生破损。应当立即停车检查轮胎是否漏气或需要更换备胎,如果继续行驶随时都有可能发生爆胎的情况。
注意事项
有的指示灯亮起说明汽车的某一装置出现问题,此时就需要停车检查。
机油故障灯。一般车黄灯可继续行驶,红灯立即停车联系服务站。
是机油故障灯:
机油故障灯被点亮的原因是:
1、机油油量不足,使机油泵的泵油量减少或因进空气而泵不上油,致使机油压力下降;
2、发动机温度过高,容易使机油变稀,从配合间隙中大量流失而导致油压下降;
3、当机油泵零部件损坏或因磨损、装配等问题出现间隙过大时,将会造成机油泵不出油或出油不足的故障;
4、曲轴与大、小瓦之间的配合间隙不当,过紧会使机油压力升高,过松会使机油压力降低;
5、机油滤清器、吸油盘堵塞同样会使机油压力降低;
6、回油阀损坏或失灵:若主油道回油阀弹簧疲劳软化或调整不当,阀座与钢珠的配合面磨损或被脏物卡住而关闭不严时,回油量便明显地增加,主油道的油压也随之下降;
7、机油选用不当:如果用错或牌号选用不当,发动机运转时会因机油粘度太低而加大泄漏量,从而使油压降低;
8、机油管路中有漏油、堵塞现象。
