APPARATUS AND METHOD FOR COLD START OF ENGINE USING MIXING FUEL OF ALCOLE AND GASOLINE

摘要

The present invention relates to a cold start apparatus and method for an engine using an alcohol-gasoline mixed fuel, and more particularly, to an apparatus for improving the startability of an engine during cold start of an automobile using an alcohol-gasoline mixed fuel, and It is about a method. In the case of a vehicle using a typical alcohol-gasoline mixed fuel, when the alcohol content is high, when the coolant temperature signal is less than or equal to a predetermined value, alcohol is injected into the cylinder without being completely vaporized, so that starting is not started and engine startability is deteriorated. There was a problem. Accordingly, the present invention, if the alcohol content is more than the predetermined value and the coolant temperature is less than the predetermined value based on the coolant temperature signal and the alcohol content information of the mixed fuel of the main fuel tank, the alcohol in the auxiliary fuel tank through the injector provided separately By initial injection of the engine by injecting a low content of alcohol-gasoline mixed fuel into the cylinder, it is possible to improve the initial startability of the engine during cold start.;Car, alcohol, mixed fuel, gasoline, cold start, coolant temperature
