| titleOfInvention | Method of dynamically estimating the fresh air flow rate supplied to an engine with high-pressure and low-pressure egr circuits |
| abstract | The invention relates to a method of estimating the fresh air flow rate entering an engine, notably a diesel engine, supercharged by a turbocharger (30), equipped with at least one intake manifold (20) of volume V coll , with an exchanger (14), with an air filter (16), with a high-pressure EGR circuit (10), with a low-pressure EGR circuit (40), with an inlet butterfly (13), with an exhaust butterfly (42), with a flow meter (52), with a pressure sensor (50) and a temperature sensor (51) and with a pipe of volume V coll between the flow meter (52) and the inlet of the intake manifold, characterized in that it comprises a step of measuring temperature T ape , pressure P coll and fresh air flow rate Q débitmètre through the flow meter (52), a step of calculating the engine flow rate Q mot , a step of calculating the mass of gas between the flow meter (52) and the inlet to the intake manifold (20), a step of calculating the mass of gas in the manifold (20), a step of measuring or estimating the high-pressure EGR flow rate, a step of calculating the flow rate of gas through the manifold (20), a step of calculating the level of low-pressure EGR at the inlet manifold (20), a step of calculating the mass of air between the flow meter (52) and the inlet to the manifold, a step of calculating the estimated level of EGR and a step of estimating the dynamic air flow rate from the engine flow rate and from the level of EGR at the inlet to the engine using expression (I). |
