Intelligent multi-oil-tank fuel oil filling system and method

Abstract

The invention belongs to the technical field of vehicle fuel oil filling devices, and particularly discloses an intelligent multi-fuel-tank fuel oil filling system and method. The system comprises a filling pipe assembly, an oil pump and control valve controller, an oil tank switching valve, a first oil tank and a second oil tank. The method comprises the steps that the working state of the oil tank switching valve is judged, if the oil tank switching valve works normally, the working oil tank is judged according to a signal of the oil tank switching valve, and then the control valve is controlled to communicate the oil storage cavity with the working oil tank so as to control the oil pump to preferentially fill fuel oil into the working oil tank; and if the oil tank switching valve cannot work normally, the control valve is controlled to communicate the first oil tank with the second oil tank so as to control the oil pump to guide the fuel oil in the first oil tank into the second oil tank or guide the fuel oil in the second oil tank into the first oil tank. By arranging one filling pipe system, the fuel filling problem of multiple fuel tanks and the filling pipe integration problem that multiple fuel tanks are affected by whole vehicle arrangement and are difficult to achieve are solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle fuel filling devices, and more specifically relates to an intelligent multi-tank fuel filling system and method. Background technique [0002] In the prior art, the fuel filling of the diesel fuel tank is generally filled through the filling pipe, and some large truck fuel tanks are not provided with the filling pipe, and the fuel tank cap is directly installed on the fuel tank, but for some light commercial vehicles or off-road vehicles , will be equipped with a filling pipe, the main reason is that the fuel filler is installed on the body surface or other upper surface, and the fuel tank is hidden inside the chassis. It is necessary to design a filling pipe to introduce fuel from the fuel filler into the fuel tank. The design of the filling pipe generally requires the installation of a fuel inlet pipe and a breather pipe at the same time. The fuel flows in from the filler pipe cap, enters the fu...

Problems solved by technology

Moreover, if the fuel tank is arranged on one side, it will be very difficult to arrange the filling pipe on the other side. The main reason is that the slope of the filling pipe is not enough, and the filling is very slow. At the same time, it is affected by the layout of the whole vehicle. The filling pipe and vent pipe on the other side cannot be arranged continuously downward, and there will be U-shaped sections and other situations that make filling difficult
