Method of exhaust gas management in internal combustion engines, corresponding system, engine, vehicle and computer program product

A motor vehicle, comprising:

• an internal combustion engine;
• and
• an engine control system configured to control the internal combustion engine, the engine control system including:
• an engine control module sensitive to a sensing signal indicative of an operating condition of an internal combustion engine and configured to produce, as a function of the sensing signal, an exhaust gas recirculation control signal for controlling an amount of exhaust gas recirculated to the internal combustion engine
• a particulate size distribution module configured to produce a particulate size distribution signal indicative of a particulate size distribution in the exhaust gas of the internal combustion engine based on the operating condition of the internal combustion engine and the amount of exhaust gas recirculated to the internal combustion engine and
• a correction module configured to produce a corrected exhaust gas recirculation control signal based on the particulate size distribution signal to control the particulate size distribution in the exhaust gas by adjusting the amount of exhaust gas recirculated to the internal combustion engine as a function of the corrected exhaust gas recirculation control signal.

A non-transient computer readable medium including instructions that cause at least one computer to implement a method including:

• sensing a sensing signal indicative of an operating condition of an internal combustion engine
• producing, as a function of the sensing signal sensed, an exhaust gas recirculation control signal for controlling an amount of exhaust gas recirculated to the internal combustion engine
• producing a particulate size distribution signal indicative of a particulate size distribution in the exhaust gas of the internal combustion engine based on the operating condition of the internal combustion engine and the amount of exhaust gas recirculated to the internal combustion engine
• producing a corrected exhaust gas recirculation control signal based on the particulate size distribution signal and
• controlling the particulate size distribution in the exhaust gas by adjusting the amount of exhaust gas recirculated to the internal combustion engine based on the corrected exhaust gas recirculation control signal.
