Automobile gasoline and alcohols mixed using method, fuel supplying system and controller

Abstract

The invention provides a mixed using method of vehicle gasoline and alcohol, the fuel supply system and the controller. When the engine is in idling condition the alcohol nozzle is in closed condition and the assistant controller receives control data of main controller to control gasoline nozzle so that the engine works. When the idling load of engine changes the oil injection quantity can be adjusted according to the presetting condition by main controller. After the engine deviates from the idling speed the oil injection quantity of gasoline nozzle is locked in the oil injection quantity in idling speed. Alcohol nozzle works according to the oil injection quantity set by main controller and the function of accelerating enrichment and decelerating oil cutoff is maintained. Under the precondition that good running performance of vehicle can be insured, alcohol adding quantity with the maximum proportion is realized; gasoline consumption can be decreased; gasoline resource can be saved; economic cost of vehicle fuel is decreased; and the pollution to atmosphere circumstance. It is provided with good economical benefit and social benefit.

Description

technical field [0001] The invention relates to a method for mixing automobile gasoline and alcohols, a fuel supply system and a controller, which are used for mixing gasoline and alcohols, a fuel supply system and a controller for electronic injection vehicles, belonging to automobile fuel supply and control system. Background technique [0002] With the rapid development of our country's economy and the remarkable improvement of people's living standards, our country is not only a big car production country, but also has gradually become a big car use country. Cars are entering thousands of households at an unprecedented speed. A country with a large number of automobiles must consume a considerable amount of energy in automobiles. Besides, this is not a problem of our own country, it is a serious problem facing the whole world. The global increase in oil prices and gasoline prices has impacted the industry and has had a considerable impact on car users. Both automobile...

AI Technical Summary

Problems solved by technology

This method only focuses on the problem of alcohol gasification, the system is complex and huge, and the structure of the fuel injection system of the original car engine needs to be changed, it is only suitable for cars with carburetors, and cannot adapt to the application of EFI cars

In particular, the essential problem of dual fuel is not solved according to the different fuel requirements of the engine under different working conditions of idling speed and high speed.
