Cold starting method of an internal combustion engine fueled with a mixture of fuels containing ethanol

摘要

A method for cold starting an internal combustion engine (1) fed with a mixture of fuels containing ethanol, comprising at least one cylinder (3) which receives a fuel fluid from an adduction duct (6) through a respective one A suction valve (7) and an aspiration manifold (6 *) defined between the suction valve (7) and the flow control device (11) of the fuel fluid entering the cylinder (3); The method comprises detecting the temperature (t) of the fuel mixture containing ethanol and the pressure (patm) of the fuel fluid entering the cylinder (3); And in the vessel in which the temperature (t) of the ethanol-containing fuel mixture is not sufficient to allow the vaporization of the ethanol as a function of the pressure (patm) of the fuel fluid to effect a reduction in the pressure inside the suction manifold (6 *) ,
