Abstract

A method for managing the mass of fuel injected into the cylinder of an internal combustion engine fed by direct injection. The pressure and the pressure drop per unit of time are monitored () during the starting phase. If the pressure becomes too low (), or if it drops too quickly (), the mass of fuel injected on each cycle is adjusted () in order to maintain a high fuel pressure in the injector (). The method can be applied, for example, in the event of low-temperature starting using any type of fuel, for example pure or mixed ethanol.
