Abstract
The present invention is a method for reducing misfire in a cylinder of an internal combustion engine. The method includes detecting a misfire event frequency that is equal to or greater than a first predetermined value, determining a pulse-width signal for a fuel injector associated with the cylinder during the misfire event, increasing the pulse-width signal if the misfire event is frequency is below a second predetermined value, and reducing the increase in the pulse-width signal if the misfire event frequency is below the first predetermined value.
