Abstract

The invention discloses a system for assisting low-temperature starting of alcohol type automobiles. The system comprises a temperature collecting unit, an engine control unit, a heating and controlling unit and a heating unit, wherein the temperature collecting unit is used for continuously collecting temperature of cooling liquid of engines of alcohol type automobiles and outputting real-time temperature; the engine control unit is connected with the temperature collecting unit and is used for generating a first control signal according to the real-time temperature and outputting the first control signal; the heating and controlling unit is connected with the engine control unit and is used for converting the first control signal output by the engine control unit according to a preset signal conversion strategy, generating a second control signal and outputting the second control signal; the heating unit is connected with the heating and controlling unit and is used for heating alcohol fuels in the alcohol type automobiles according to the second control signal output by the heating and controlling unit. The system has the beneficial effects that the alcohol fuels in fuel rails of the engines are heated, the temperature of the alcohol fuels can be improved before the alcohol fuels are sprayed, the atomization effect is improved, and the problem of difficult low-temperature cold starting of the alcohol type automobiles is solved.

Description

technical field [0001] The invention relates to the field of cold start of ethanol automobiles, in particular to a low-temperature auxiliary start system and method for ethanol automobiles. Background technique [0002] Fuel ethanol can be processed from raw materials such as grain and various plant fibers, and is a new type of clean energy. Ethanol fuel refers to a fuel that is made by adding a certain proportion of fuel ethanol to gasoline components according to the volume ratio and mixing them through a specific process. The use of ethanol fuel instead of traditional fuel can reduce the dependence on non-renewable resources such as petroleum, and has the following advantages: the combustion products are water and carbon dioxide, high environmental protection performance; high octane number, good antiknock performance; high oxygen content, which is conducive to Full combustion; convenient storage and transportation. [0003] Passenger cars currently on the market use ga...
