Foton light truck throttle increases engine abnormal sound.

What you want to ask is the reason why the abnormal sound of Futian light truck engine increases with the increase of throttle? According to the Pacific Auto Network, the exhaust pipe is leaking and the throttle is dirty.

1, the exhaust pipe is leaking. When there is air leakage in the intake and exhaust pipes, the speed of vehicle speed-up and exhaust is accelerated, and the vehicle will have a loud roar.

2. The throttle valve is dirty. When the car accelerates, the load of the engine begins to increase, and the throttle opening should be increased at this time. If the throttle opening is not opened to a better position due to dirty blockage, the mixing ratio of the engine will be poor and noise will be generated when accelerating.
