Dongfeng Tianlong refueling sometimes sounds like automatic refueling, and the speed is not high.

The reason is the problem of automobile oil system and the fault of throttle position sensor. The problem of automobile oil system will lead to the fuel not flowing into the engine normally when refueling, and the fault of throttle position sensor will lead to too much or too little fuel injection, which will lead to abnormal noise when refueling. Dongfeng Tianlong is a new generation of heavy truck platform launched by Dongfeng Commercial Vehicle Company in Shiyan City.
