Embodiment Construction

[0040] In order to make the above objects, features and advantages of the invention more obvious and comprehensible, specific implementations of the invention will be described in detail below.

[0041] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.

[0042] Such as figure 1 As shown, the invention provides a method for improving the low-temperature volatility of ethanol fuel, which includes:

[0043] Collect the intake air temperature measured by the intake air temperature sensor;

[0044] To determine whether the intake air temperature is lower than the cold-start intake air temperature threshold, those...

Abstract

The invention provides a method for increasing low-temperature volatility of ethanol fuel and a cold starting system for ethanol-fuel cars. The method includes: collecting the gas inlet temperature acquired by a gas inlet temperature sensor; judging whether the gas inlet temperature is lower than a gas inlet temperature threshold or not; if so, closing an electronic throttle valve; collecting the engine revolution acquired by an engine rotation speed sensor; gradually increasing the openness of the electronic throttle valve when the engine revolution reaches the preset revolution. The method for increasing low-temperature volatility of the ethanol fuel and the cold starting system for the ethanol-fuel cars have the advantages that the pressure of an gas inlet manifold is lowered by closing the electronic throttle valve, the volatility of the ethanol fuel can be increased by lowering the pressure of the gas inlet manifold, energy saving is achieved, and fast cold starting of the ethanol-fuel cars is achieved.

Description

technical field [0001] The invention relates to the field of automobile cold start, in particular to a method for improving the low-temperature volatility of ethanol fuel and an ethanol fuel automobile cold start system. Background technique [0002] Fuel ethanol can be processed from raw materials such as grain and various plant fibers. It is a new type of clean energy. Ethanol fuel refers to a gasoline component that is mixed with a certain proportion of fuel ethanol by volume and mixed through a specific process. kind of fuel. 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] The volatility of fuel ethanol in ethano...
