Abstract
A method to determine the injection pattern in the intake stroke of the combustion cycle of the cylinders of a direct-injection internal combustion engine, which includes determining the overall quantity of fuel to be injected for each combustion cycle of each cylinder during the intake stroke; determining the maximum quantity of fuel to be injected for each partial injection as a function of the value of the start of injection angle, of the speed and of the load of the internal combustion engine; and determining the number of partial injections and the objective quantity to be injected for each partial injection as a function of the quantity of fuel to be injected for each combustion cycle of each cylinder during the intake stroke and of the maximum quantity of fuel to be injected for each partial injection.
