It is hereby disclosed a method of controlling an injection apparatus of an internal combustion engine including setting a minimum value (QMIN) of a fuel quantity that can be injected into the internal combustion engine by the injection apparatus with one injection; preventing the injection apparatus from performing post-injections of fuel quantities having a smaller value than the minimum value (QMIN).

Method of controlling an injection apparatus of an internal combustion engine

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.

Method to determine the injection pattern in the intake stroke of the combustion cycle of the cylinders of a direct-injection internal combustion engine

A method to determine the injection pattern in the compression stroke of the combustion cycle of the cylinders of a direct-injection internal combustion engine, comprising the steps of determining the initial quantity of fuel and an objective quantity of fuel to be injected for each partial injection of a maximum number of partial injections; determining an effective quantity of fuel to be injected for each partial injection as a function of the respective initial quantity of fuel and of the respective objective quantity of fuel; and determining an objective pattern of partial injections to be performed in the compression stroke as a function of the value of the end of injection angle and of the effective quantity of fuel to be injected for each partial injection of a maximum number of partial injections to be performed in the compression stroke.
