Embodiment 1

[0018] Embodiment 1: as figure 1 In the shown embodiment, a fuel supply system for methanol automobiles includes a main oil tank body 1 and an electric injection device 2. The main oil tank body 1 includes a methanol tank 3 and a gasoline tank 4 separated from each other. The volume of the tank 3 is 5 to 20 times that of the gasoline tank 4, the methanol tank 3 is connected to the liquid inlet of a methanol pump 5, the gasoline tank 4 is connected to the liquid inlet of a gasoline pump 6, and the electric injection The device 2 is communicated with the outlet end of the methanol pump 5, and the injection end of the electronic injection device 2 is communicated with the engine intake pipeline. The main oil tank body 1 is provided with methanol filling tanks communicated with the methanol tank 3 and the gasoline tank 4 respectively. Port 7, gasoline filling port 8, the methanol tank 3 is provided with an alcohol removal pump 9, the liquid inlet end of the alcohol removal pump 9 ...

Embodiment 2

[0019] Embodiment 2: the basic structure and implementation mode of this embodiment are the same as embodiment 1, and its difference is, as figure 2 , image 3 As shown, the methanol tank 3 is provided with a cage 10, the cage 10 is provided with a float 11, and the surface of the cage 10 is provided with a plurality of oil holes 12, and the height of the float 11 is Greater than 90% of the height of the methanol tank 3, the top end of the cage 10 is provided with a gasoline liquid inlet 24 connected to the liquid inlet of the gasoline pump 6, and the side of the top section of the float 11 connects the gasoline liquid inlet 24 blocked. When the methanol in the methanol tank 3 is sufficient or still enough to supply the engine, the float 11 is all floating on the top, so that the gasoline inlet 24 is always blocked, and gasoline cannot enter the methanol tank 3, which can avoid a large amount of mixing of gasoline and methanol This leads to unstable operation in the combust...

Abstract

The invention discloses a fuel supply system for methanol automobiles, aiming to provide a fuel supply system that can effectively reduce the number of electric fuel injection parts in methanol automobiles, and realize dual fuel supply by utilizing the methanol electric fuel injection system, which has low cost and can avoid fuel switching. Safety problems caused by mass mixing, good stability and long service life of methanol vehicle fuel supply system. It includes the main oil tank and electric injection device. The main oil tank includes methanol tank and gasoline tank. The methanol tank is connected to the liquid inlet of a methanol pump. The gasoline tank is connected to the gasoline pump. There are methanol filling port and gasoline filling port. The methanol tank is equipped with an alcohol discharge pump, and the liquid outlet of the gasoline tank is connected to the methanol tank. The beneficial effects of the present invention are: a set of electric injection system can be shared, which reduces the cost and improves the compactness of the structure; it can ensure the purity of the fuel and maintain the stability of the work; the methanol will not be wasted and will enter the recovery box and can be reused Wait.

Description

technical field [0001] The invention belongs to the field of methanol automobiles, in particular to a fuel supply system for methanol automobiles. Background technique [0002] Methanol vehicle, also called methanol fuel vehicle, is a vehicle that uses methanol as the main fuel, and can also use gasoline as fuel. It is a new type of vehicle with energy-saving and environmental protection technology that can be flexibly converted from methanol to gasoline fuel. It can also be refitted by ordinary vehicles. made. Generally speaking, the fuel tank of a methanol fuel vehicle is divided into two fuel tanks. The small fuel tank is filled with gasoline, and the large fuel tank is filled with methanol. The middle of the fuel tank is closed, and the two fuels are stored separately. When the methanol runs out, gasoline can be used as a backup fuel to enable the car to stick to the methanol gas station. In current methanol vehicles, the engine EFI system is two independent oil supply...
