First Claim
Patent Images
1. A method of adjusting fuel injections to an engine, comprising:
- adjusting an amount of a fuel injection to an engine based on an ethanol content of fuel in a port puddle, including determining a transient fuel compensation based on the ethanol content and a vapor pressure of the fuel in the port puddle and adjusting a desired amount of injected fuel based on the transient fuel compensation.

Abstract
A method adjusts fuel injection to account for fuel puddling in the engine intake. The fuel is adjusted based on the ethanol content of the fuel in the puddle, and the make-up of the various fuel components in the puddle. In this way, it is possible to better account for the effects of these parameters on puddle evaporation.
