  • Method of reducing icing-related engine misfires
    Patent number: 8170772
    Abstract: 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.
    Type: Grant

  • System and method for crankcase gas air to fuel ratio correction
    Patent number: 8141545
    Abstract: A method and a system for correcting combustion in an engine to control for the effect of crankcase gases in the intake system are disclosed. The system includes one or more sensors in the crankcase ventilation system. An air to fuel ratio sensor may be disposed within a breather line and/or a PCV line of the crankcase ventilation system to monitor crankcase gases.
