Dongfanghong, big pump truck, hot car can't catch fire 95

What you want to ask is how to solve the problem that a big pump truck and a hot car can't catch fire in Dongfanghong? There is too much carbon deposit in the throttle valve, and the pressure of the oil pump is insufficient.

1. If the throttle has too much carbon deposit or the throttle is pulled, the idle motor has too much carbon deposit and blocks the bypass air passage. In this case, you can step on the accelerator at the same time when you start, so that you can get more air and start more smoothly.

2. If the pressure of the oil pump is not enough to release the pressure of the fuel pipeline, the key can be turned on and off many times before starting. At this time, every time the key is turned on, the oil pump will be energized for three seconds, and the oil circuit pressure will increase. Repeat several times before you start.
