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 16):
An engine system, comprising:\n a first cylinder; a second cylinder; a first fuel injector coupled to a first intake port of the first cylinder; a second fuel injector coupled to a second intake port of the second cylinder; and a controller with computer readable instructions stored on non-transitory memory for:\n responsive to a drop in torque demand, selectively deactivating the second cylinder while continuing to fuel the first cylinder for a number of cylinder events; and \n on each event for the number of cylinder events,\n updating a value of a first fuel puddle in the first intake port via a first set of fuel evaporation constants; \n updating a value of a second fuel puddle in the second intake port via a second, different set of fuel evaporation constants until the fuel puddle is at a saturation limit, and then maintaining the value of the second fuel puddle; and \n adjusting a pulse-width commanded to the first fuel injector based on the value of the first fuel puddle.
