METHOD OF CONTROLLING THE BURNT GAS FRACTION IN AN ENGINE CYLINDER WITH EGR AND IGR |
摘要 |
The invention relates to a method of controlling an internal-combustion engine (1) equipped with an exhaust gas recirculation circuit and with variable timing means, having a first actuator (8) and of a second actuator (9). The method comprises acquiring a torque setpoint for said engine Tqsp determining a position setpoint for the first actuator (8) VVTint and a position setpoint for the second actuator (9) VVTexh by using a burnt gas flow model (MEGB) that relates the position setpoints of the actuators to the engine torque setpoint Tqsp. The burnt gas flow model (MEGB) comprises a cylinder filling model (MR), the burnt gas fraction in the cylinder is controlled by applying position setpoints VVTint and VVTexh to the variable timing means (8 and 9). |
