Low-pressure oil supply system for diesel vehicle

Abstract

The invention relates to a low-pressure oil supply system of diesel vehicle, which comprises: an oil tank, an oil tube connected to the oil tank, and an oil pump at the oil tube, wherein the oil tank is connected to one small oil storage tank whose outlet is connected to the oil tube; the small oil storage tank and the oil tube are packed with electric heating film connected to the power source. The invention has the advantages that: 1, the oil tank is connected to one small oil storage tank to increase and keep the temperature of small oil storage tank, with high speed, better thermal-insulated effect, and low power consumption; 2, the invention uses polyester dual-surface insulated electric heating film, with better flexibility, whose resistance can be selected according to needed power; 3, the oil tank has heat radiation tube to utilize the heating system to avoid condensing the diesel.

Description

(1) Technical field [0001] The invention relates to a low-pressure oil supply system for a diesel vehicle. (2) Background technology [0002] As we all know, diesel vehicles running in winter, due to the low temperature, often freeze and condense the diesel in the fuel tank and oil pipeline, which makes the oil circuit waxy and clogged, and cannot supply fuel to the engine normally, affecting the driving of the vehicle. Especially for vehicles that use low-grade diesel fuel when driving from the warm south to the cold north or into the mountains, the diesel is easy to condense due to the large temperature difference. If you run into this situation in the alpine and remote mountainous areas, the vehicle cannot be used, and the people and the vehicle are in a low-temperature environment for a long time, which is prone to frostbite and even endangers the lives of the drivers and passengers. In the north in winter, it is often seen that drivers use open flames to grill the fuel...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the deficiencies in the prior art that diesel vehicles condense when they are parked overnight in winter or when driving, the thermal insulation and heating devices of the diesel oil consume a lot of power, the heating time is long, the safety is poor, and the original performance of the vehicle is seriously affected. Low-pressure fuel supply system for diesel vehicles with low power consumption, short heating time, good heat preservation effect, good safety, heat preservation and heating diesel that will not affect the original performance of the vehicle
