MASS AIR FLOW SENSOR SIGNAL COMPENSATION SYSTEM |
摘要 |
A method and system are disclosed for compensating a mass air flow signal produced by a mass air flow sensor in fluid communication with an air intake passageway of an internal combustion engine. A mass air flow signal produced by the mass air flow sensor is monitored and an expected oxygen concentration of exhaust gas produced by the engine is determined. A compensation parameter is determined as a function of the expected oxygen concentration and a measured value of the oxygen concentration of the exhaust gas. A compensated mass air flow value is determined as a function of the mass air flow signal and the compensation parameter. |
