摘要： An EGR control method to prevent condensation within the EGR system uses a temperature sensor signal from an EGR cooler exhaust gas outlet to model or estimate exhaust manifold gas temperature upstream of the cooler. If the estimated exhaust manifold gas temperature falls below a predetermined level, the engine control system closes or partially closes the EGR control valve to stop EGR flow through the cooler and the EGR valve.

摘要： According to at least one aspect of the present technology, a method is provided for compensating the output of a mass air flow sensor in response to humidity level. The method includes determining an actual mass air flow value (MAF_ACT) using the mass air flow sensor. The method also includes determining an actual humidity value (HUM_ACT) of the air flow that is measured by the mass air flow sensor. The method further includes determining if the actual humidity value (HUM_ACT) is outside of a preselected operating range. If the actual humidity value (HUM_ACT) is outside of the preselected operating range, the method determines a humidity-compensated mass air flow value (MAF_HUM) as a function of the actual mass air flow value (MAF_ACT) and the actual humidity value (HUM_ACT).
