METHOD FOR THE INJECTION COMPUTATION FOR AN INTERNAL COMBUSTION ENGINE
First Claim
Patent Images
1. A method for injection computation for an internal combustion engine, comprising:
- ascertaining an adaptation factor, which represents aging of fuel, from a model of the fuel and from fuel outgassing via a tank vent; and
adapting, using the adaptation factor, at least one of a fuel injection quantity and a fuel injection time.

Abstract
A method for the injection computation for an internal combustion engine, in particular for a gasoline range extender engine. This includes ascertaining an adaptation factor, which represents fuel aging, from a model of the fuel and a fuel outgassing via a tank vent and adaptation of a fuel injection quantity and/or a fuel injection time using the adaptation factor.
