From effect, while playing pumping effect.The trend of its diesel oil is：Diesel oil is pumped out from fuel tank 11, through oil pipe 14 to diesel oil
Filter 15 filters, and most enters engine through oil pipe afterwards, extra diesel oil is back to by oil pipe in fuel tank 11.However, due to existing
There is technology that only there is single oil box, and 11 inside of fuel tank only fills the diesel oil of single label, causes vehicle after cold district rests,
After especially placing a night, diesel oil crystallization causes vehicle not start normally, needs to light a fire and be toasted to fuel tank 11, causes the time
With the waste of energy, and its safety is relatively low；If all filling low-grade diesel in fuel tank 11, and the big of cost can be caused
Amount increases.
