摘要:
A control system for a vehicle includes a first counter that indicates a first count of a number of cylinders of an engine of the vehicle that are fueled. A second counter indicates a second count of the number of cylinders that are fueled. A control module determines a secure count based on the first count and the second count. The control module adjusts torque output of the engine based on the secure count.

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.

A fuel control system includes a pressure comparison module that generates a pressure control signal when a fuel supply pressure is greater than a predetermined pressure value, a temperature comparison module that generates a temperature control signal when a temperature of an engine is greater than a predetermined temperature value, and a pre-crank fuel module that selectively dispenses pre-crank fuel prior to cranking the engine based on the pressure control signal and the temperature control signal. A related fuel control method is also provided.

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.

A method comprises detecting a status of a transfer pump for transferring fuel between a first fuel source and a second fuel source; receiving a fuel trim value and a vehicle operating parameter; and calculating a fuel composition of one of the first fuel source and second fuel source based on the fuel trim value, the transfer pump status and the vehicle operating parameter. A control module comprises a secondary pump transfer module detecting a status of a transfer pump for transferring fuel between a first fuel source and a second fuel source; and a fuel composition estimation module in communication with the secondary pump transfer module, receiving a fuel trim value and a vehicle operating parameter, and calculating a fuel composition of one of the first fuel source and second fuel source based on the fuel trim value, the transfer pump status, and the vehicle operating parameter.
