Abstract
A control system for controlling fuel delivery to an internal combustion engine (ICE) based on oil diluted by fuel in a crankcase of the ICE includes a fuel injector and a controller. The controller is configured to determine a modeled evaporation rate of unburned fuel in the crankcase; compare the modeled evaporation rate of unburned fuel to a threshold; and communicate a fuel delivery signal indicative of an injector fuel mass target to the fuel injector to compensate the fuel injected based on the modeled evaporation rate of the unburned fuel in the crankcase exceeding the threshold.
