Abstract
The invention relates to a method of controlling an internal-combustion engine () equipped with an exhaust gas recirculation circuit and with variable timing means, having a first actuator () and of a second actuator (). The method comprises acquiring a torque setpoint for the engine Tdetermining a position setpoint for the first actuator ()and a position setpoint for the second actuator ()by using a burnt gas flow model (MEGB) that relates the position setpoints of the actuators to the engine torque setpoint T. The burnt gas flow model (MEGB) comprises a cylinder filling model (MR), the burnt gas fraction in the cylinder is controlled by applying position setpointsandto the variable timing means (and).
