Abstract
The present invention relates to a method for controlling an internal combustion engine having a means () for directly injecting fuel as well as a means () for admitting at least one fluid into the combustion chamber, a cylinder (), a burned-gas exhaust means (), and a processing and control unit () receiving information on at least the driver's torque demand and the engine speed (Ne), comprising a) determining the desired torque (Torque_des) corresponding in particular to driver demand; b) from this desired torque, determining a desired Indicated Mean Effective Pressure (IMEP_des) from which the parameters (Mair_sp, BGR_sp) are established to control admission of at least one fluid into the combustion chamber; and c) determining a specified value of the IMEP (IMEP_sp) from the desired IMEP and at least one magnitude linked to the fluid admitted into the combustion chamber, to define the fuel injection parameters (Mfuel_i, SOI_i, Pfuel) in the combustion chamber.
