Abstract

The invention relates to a control method of methyl alcohol flexible fuel vehicle and a system thereof. The system comprises a mixed fuel feeding system, an electronic control system and an engine, wherein, mixed fuel in a mixed fuel box comprises methyl alcohol and auxiliary fuel as the balance. A fuel recognition sensor is used for recognizing methyl alcohol content in fuel, corresponding data is transmitted to a data processing unit, the data processing unit analyzes the data and transmits a result to a central control unit, and the central control unit chooses a corresponding working module to adjust the corresponding control parameter, which ensures that the engine works at the optimum state. The invention mainly provides a control system of a methyl alcohol flexible fuel vehicle, which can add mixed fuel at any ratio to the mixed fuel box, needs no additives, has favorable starting performance and high dynamic property and discharges cleanly. The invention solves the technical problems that the fuel supply is out of control because of methyl alcohol-petrol mixed fuel delamination and vehicle starting performance is lowered in the prior art.

Description

technical field [0001] The invention relates to a mixed fuel vehicle, in particular to a control method and system for a methanol flexible fuel vehicle. Background technique [0002] With the development of industrial technology, automobiles have become an important means of transportation for people. At present, the main fuel for automobiles is gasoline, which is a non-renewable fuel and causes pollution to the environment. New types of fuels are expected, and now the fuels used in automobile engines are beginning to diversify. Methanol has a wide range of raw materials, and the transportation, storage, filling and use of products are similar to gasoline and diesel fuel for internal combustion engines currently available on the market; methanol has a high octane number, complete oxygen-containing combustion, and a higher ignition temperature than gasoline , the combustion process is safe, and it is an ideal alternative fuel for vehicles. [0003] However, methanol also h...
