Abstract
The invention discloses a dual-fuel feeding device and a control system. The feeding device comprises a methanol fuel pump, a gasoline fuel pump, a fuel injection system and an engine, wherein tail ends of fuel outlet pipelines of the methanol fuel pump and the gasoline fuel pump are respectively connected the fuel injection system which is connected with the engine, and temperature control switches are arranged on the two fuel outlet pipelines. The control system comprises an electronic control unit (ECU), a signal input end, a microcomputer and a driving circuit which are connected in sequence. The control system further comprises storage batteries which are connected with the signal input end, the microcomputer and the driving circuit respectively through a voltage-stabilized power supply to provide power. The processor is connected with a work state transition switch and a parameter regulation switch, and the ECU is connected with the engine and the temperature control switches. The dual-fuel feeding device and the control system solve the problem of cold start caused by the fact that single fuel tank burns methanol gasoline, good startability of automobiles at the low temperature is ensured, exhaust gas emission is reduced to the greatest extent, and energy conservation and emission reduction can be achieved.
Description
Technical field
The present invention relates to vehicle fuel system, be specifically related to a kind of alcohols/gasoline two-fuel feeder and control system.
background is technology
Along with the raising of China's expanding economy and people's living standard, people's car owning amount is more and more higher.China is not only Yi Ge automobile production big country now, is also that an automobile uses big country, and the just former speed not having of automobile is come into our huge numbers of families.Vehicle fuel is mainly gasoline and diesel oil at present, and these fuel are mainly derived from fossil fuel oil.And China is a rich coal oily country less, so Develop coal-based alternative energy sources has certain strategic importance.
Methyl alcohol is the fuel of gasoline, diesel oil as an alternative, there is lot of advantages, for the fuel combination of gasoline and alcohols or the independent fuel people of alcohols, done a lot of research work, obtained certain achievement, but a high proportion of methanol gasoline of current combustion, problem of ubiquity is exactly cold start-up.The current also bifuel system of useful methyl alcohol and gasoline, but the method system complex is huge, need to change motor injection system structure, recondition expense is very high cannot obtain large-scale popularization, and is not suitable for present electro jet car.
Therefore, the above-mentioned defect existing in order to overcome prior art, researches and develops a kind of repacking cheaply, and dual-fuel controller simple in structure, has certain realistic meaning.
Summary of the invention
The object of this invention is to provide a kind of fuel supplier and control system.
The present invention is achieved by the following technical solutions:
