Abstract
A control system for controlling the fueling of an engine assembly. The engine assembly includes an internal combustion engine, a fuel control system, a fuel vapor storage canister and a purge control system for purging the fuel vapor storage canister. The control system includes a purge fuel vapor measuring device for measuring an amount of purge fuel vapor flowing from the vapor storage canister to the internal combustion engine, a fuel corruption estimating device for estimating an amount of fuel corruption as a function of the amount of purge fuel vapor flowing from the vapor storage canister to the internal combustion engine and a controller for adapting the control of the internal combustion to the estimate of the amount of fuel corruption. A method for fueling an engine assembly having an internal combustion engine is also provided.
