Abstract:
Methods and systems are provided for tracking a fuel puddle mass in the intake port of a deactivated engine cylinder. The difference in fuel evaporation rate in the deactivated cylinder intake is accounted for by applying distinct time constant and gain values to a transient fuel compensation model. A fuel vapor content is clipped once the intake vapor pressure in the intake port of the deactivated cylinder reaches a saturation pressure limit.

Claim (Index 7):
The method of  claim 6 , wherein the saturation vapor pressure is estimated based on each of fuel alcohol content, ambient pressure, and port temperature of the deactivated cylinder, the method further comprising estimating each of the fuel puddle mass and the vapor content in the port of the other active cylinders via the model.
