What is the reason for the oil lamp to light up during idling but not during acceleration?机油泵出现故障。

How to solve the problem of the oil lamp lighting during idling but not during acceleration:应及时熄火并联系维修厂过来检修。

The function of the oil pump:机油泵大都是由曲轴通过皮带或者齿轮的方式带动，发动机启动的同时，机油泵也开始工作。机油泵负责将油底壳处的机油通过油道输送到上方的凸轮轴等地方，使得机件在高速运转时能够有充分润滑。

There are two types of oil pumps: the rotative type and the gear type. During idling, the oil pump can provide about 300kPa of pressure for the engine. If the oil pressure is too low, some parts of the engine may not get enough oil or even no oil at all, leading to increased wear.当机油压力过低，就会导致部分机件没有或得不到足够的机油润滑，导致磨损加剧。

The reason for the oil lamp to light up during idling but not during acceleration is that the oil pump is not working properly. The oil pump is responsible for supplying oil to the engine during idling and high-speed运转，如果机油泵出现故障，机油压力会降低，导致部分机件没有或得不到足够的机油润滑，从而引起磨损加剧。To solve the problem, you should turn off the engine and contact a repair factory for检修.
