    摘要: A method of controlling an engine during starting is disclosed. During cold starting and following a refueling, a default alcohol value is used to control various systems associated with the engine, including fuel injection and ignition timing. The default alcohol value is used to ensure reliable starting. During non-cold starting and following a refueling, the current alcohol value is used to minimize fuel inefficiencies.

    摘要: Methods and systems for monitoring engine coolant temperature sensors are described. In one embodiment, an expected engine coolant temperature may be determined based on the accumulated engine mass air flow. If the current engine coolant temperature is substantially different from the expected temperature, then an error signal may be generated. In one embodiment, the expected engine coolant temperature is compared to the actual engine coolant temperature if the engine coolant temperature has changed by a predetermined amount. In one embodiment, the expected engine coolant temperature is compared to the actual engine coolant temperature if the accumulated engine mass air flow is equal to or is greater than a predetermined value.

    摘要: A method of reducing icing-related engine misfires during operation of a vehicle is provided. The vehicle can include an engine and an engine control unit operable for at least partially controlling operation of the engine. The vehicle can further include a plurality of sensors in electrical communication with the engine control unit. The engine can include an air intake system and an exhaust system, wherein the air intake system can include a positive crankcase ventilation valve. The method includes predicting the presence of ice within the air intake system based upon an input to the engine control unit from at least one of the sensors.
