    摘要: An engine control system comprises a torque control module and a fueling control module. The torque control module selectively generates a deactivation signal for a first cylinder of a plurality of cylinders of an engine based on a torque request. The fueling control module halts fuel delivery to the first cylinder based on the deactivation signal. The torque control module increases a spark advance of the engine at a first time after the fueling control module halts fuel injection for the first cylinder. The first time corresponds to an initial time combustion fails to occur in the first cylinder because fuel delivery has been halted.

    摘要: A system for estimating fuel concentration comprises an ethanol estimating module that generates an ethanol estimate based on baseline closed loop corrections (CLC). A fuel system module controls fuel to an engine and generates a fuel system error. The ethanol estimating module selectively adjusts the baseline CLC and the ethanol estimate based on the fuel system error. A method for estimating fuel concentration comprises generating an ethanol estimate based on baseline closed loop corrections (CLC); controlling fuel to an engine and generating a fuel system error; and selectively adjusting said baseline CLC and said ethanol estimate based on said fuel system error.
