Abstract
The present Invention relates to a fuel injection method for a direct-injection internal-combustion engine, notably of diesel type, comprising a cylinder (10) closed by a cylinder head (16). a piston (12) comprising a bowl (18). and a fuel injector (48). According to the invention, the method consists in feeding the fuel into the bowl coated with a thermal insulation coating in at least two successive injections in quick succession so as to achieve low-temperature combustion of the fuel mixture.
