CONTROL SYSTEM FOR A MOTOR VEHICLE INTERNAL COMBUSTION ENGINE THAT COMPRISES AN ENGINE EXHAUST GAS RECIRCULATION CIRCUIT PROVIDED WITH A CONTROLLED RECIRCULATION VALVE

摘要

Control system for a motor vehicle internal combustion engine (1) supplied with supercharged air, comprising a circuit for recirculating the exhaust gases of the engine (1) that is provided with a controlled recirculation valve (18) for regulating the flow of recirculated gases, and an electronic control unit designed to calculate a correction parameter C for the opening position EGR of said recirculation valve (18), dependent on the opening position EGR of said recirculation valve (18) and on a reference supercharging pressure P₂
