Problems solved by technology

However, the use of methanol fuel in automobiles has the problem of difficulty in starting the engine. Especially in winter, alcohol fuels are difficult to evaporate and form combustible gas, so it is very difficult to start the engine.
This makes alcohol fuels subject to certain restrictions as automotive fuels

Abstract

The invention discloses a fuel control device of a dual-fuel automobile. The device comprises a first fuel box, a first fuel pump, a fuel nozzle and an engine, and is characterized by also comprising a second fuel box and a second fuel pump; the first fuel box is filled with alcohol fuel, and is communicated with the fuel nozzle through the first fuel pump and a first fuel pipe; the first fuel pipe is provided with a first check valve which prevents the alcohol fuel from flowing reversely into the first fuel box; the second fuel box is filled with gasoline, and is communicated with the fuel nozzle through the second fuel pump and the second fuel pipe; the second fuel pipe is provided with a second check valve which prevents gasoline from flowing reversely into the second fuel box; the fuel nozzle is communicated with the second fuel box through an oil return pipe which is provided with a pressure valve; the device also comprises a relay which controls the second fuel pump; a normally closed contact of the relay is connected with a conversion switch, and the other normally closed contact is connected with a bond strap; and a normally open contact of the relay is connected with the second fuel pump, and the other normally open contact is connected with a normally used fire wire. Through the fuel control device, the engine starting of the automobile is not influenced by alcohol fuel, and the engine can be started normally.

Description

technical field [0001] The invention relates to a vehicle fuel control device, in particular to a dual-fuel vehicle fuel control device. Background technique [0002] With the continuous development of society, the number of cars is increasing, and gasoline has always been its main energy source. In order to reduce vehicle exhaust pollution, dual-fuel vehicles using alcohol fuel as auxiliary fuel have appeared at present. However, the use of methanol fuel in automobiles has the problem of difficulty in starting the engine. Especially in winter, it is difficult for the alcohol fuel to evaporate and form combustible gas, so it is very difficult to start the engine. This makes alcohol fuels subject to certain restrictions as automotive fuels. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the object of the present invention is to provide a dual-fuel automobile fuel control device, which makes the automobile engine ...
