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.

1-13. (canceled)
A method of engine fuel injection, comprising:
- determining an amount of fuel evaporated from a port puddle during an intake stroke;
- and
- adjusting a fuel injection amount to the engine based on an ethanol content of fuel in the port puddle, a vapor pressure of the fuel in the port puddle, and the amount of evaporated fuel.
