Control of the combustion engine of a vehicle, especially a commercial vehicle diesel or marine diesel, based on characteristic values of the exhaust gas and operating values for the combustion unit

摘要

Control method for a combustion unit (100), especially a vehicle combustion engine with exhaust gas recirculation (101, 104, 109, 22) in which the fresh air mass flow (M21) in a suction unit is measured. The fresh air mass flow is determined using an least one operating value (RO21, RO3, ROA) that is characteristic of the oxygen content in the exhaust gas and at least one combustion characteristic value (T22, P22, M22, MK) that is representative of the operating state of the combustion unit. An independent claim is made for a control device for a combustion unit.
