  • System and method of controlling fuel delivery during positive valve overlap operation of an engine start
    Patent number: 7607410
    Abstract: An approach is provided for compensating engine fueling during starting conditions in which positive valve overlap is enabled early in the start. In one example, the valve timing is adjusted to increase positive overlap during cold starting conditions, and fuel adjustments are provided to compensate for the evaporation effects of the increased residual push-back.
    Type: Grant
