Abstract

The utility model relates to an electric heating device for an automobile fuel system capable of using No. 0 diesel oil in cold areas in winter. An electric heating jacket is arranged on an automobile fuel oil pipeline, an electric heater with a temperature control switch is arranged in a fuel tank, a protective cover with filtration is arranged outside the heater, and the diesel oil is heated firstly and then enters the automobile fuel system so as to cause the overall fuel to be heated gradually by partial heating.

Description

Electric heating device for automobile fuel system

Technical field

The utility model relates to an electric heating device for an automobile fuel system, which can heat and use 0# diesel in winter.

Background technique:

At present, the existing electric heating device cannot effectively use 0# diesel oil in winter, but only plays an auxiliary starting role in the case of low temperature.

Invention content:

In order to overcome the deficiency that the existing electric heating device cannot effectively use 0# diesel in winter, the utility model provides an electric heating device, which can not only start the car well in winter, but also effectively use 0# diesel in winter or in cold regions diesel fuel.

The technical solution of the utility model to solve the technical problem: an electric heating sleeve is provided on the fuel pipeline from the diesel engine to the fuel tank to heat and protect the fuel pipeline, and the fuel pipeline extending into the fuel tank passes through the seal set on the fuel tank. The rubber ring is inserted into the middle of the electric heater with temperature control switch arranged in the fuel tank. The electric heater with a control switch is provided with a protective cover with filtering properties. There is a hole above the protective cover, and an oil-resistant pipe with guiding and protective functions is provided between the sealing rubber ring on the fuel tank to facilitate the fuel pipe. The protective cover can protect the heater from the impact of diesel oil, filter impurities, and make the diesel heated inside first enter the automobile fuel system, and the whole fuel oil is gradually heated by local heating. The electric heater with a protective cover is flanged to the fuel tank.

When the power is turned on, the fuel pipeline and the fuel tank are heated at the same time, so that they can be used in a short time. When the fuel in the fuel tank reaches the predetermined temperature, it will automatically stop heating; if it is lower than the predetermined temperature, it will automatically start heating.

The beneficial effect of the utility model is that the use of 0# diesel oil in winter can save energy, and since the heating is performed by electricity, the pollution to the environment will not be increased. Moreover, the structure is simple and easy to install.
