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 12):
The method of  claim 11 , further comprising, updating the estimate for fuel puddle mass and vapor content in an intake port of another active cylinder on each cylinder event via a model using a first evaporation time constant and a first gain value, wherein the updating for the deactivated cylinder is via the model using a second, different evaporation time constant and a second, different gain value.
