Abstract
A method of operating a vehicle propulsion system including a motor and an engine, the method comprising of producing a motor output by selectively operating the motor to consume electrical energy stored on-board the vehicle, the motor driving the vehicle; producing an engine output by selectively operating the engine to consume fuel stored on-board the vehicle; and increasing consumption of the fuel by the engine by operating the engine based on a residence time of the fuel stored on-board the vehicle and further based on a profile of ambient conditions over the residence time.

21. A method of operating a vehicle propulsion system including a motor and an engine, the method comprising:
-
producing a motor output by selectively operating the motor to consume electrical energy stored on-board the vehicle, the motor driving the vehicle; producing an engine output by selectively operating the engine to consume fuel stored on-board the vehicle; and increasing consumption of the fuel by the engine by operating the engine based on a residence time of the fuel stored on-board the vehicle and further based on a profile of ambient conditions over the residence time. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A vehicle propulsion system, comprising:
-
an electric battery configured to store electrical energy on-board the vehicle; a fuel tank configured to store fuel on-board the vehicle; an internal combustion engine configured to consume the fuel from the fuel tank to produce an engine output; an electric motor configured to consume the electrical energy from the electric battery to produce a motor output; and a control system configured to; periodically receive electrical energy from an electrical energy source located external the vehicle; discharge the energy storage device to operate the electric motor to produce the motor output; selectively operate the engine to combust fuel stored on-board the vehicle to produce the engine output; and increase engine operation based on whether a residence time of the fuel stored on-board the vehicle is greater than a threshold, the threshold adjusted responsive to ambient conditions and fuel composition. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A method of operating a plug-in hybrid electric vehicle including an energy storage device, a motor, and an engine, the method comprising:
-
periodically recharging the energy storage device by receiving electrical energy at the energy storage device from a power source external the vehicle via an electrical energy transmission cable; identifying degradation of a parameter of fuel stored on-board the vehicle; and increasing consumption of the fuel by the engine as degradation of the parameter of the fuel increases, where increasing consumption of the fuel includes increasing operation of the engine; and
where the parameter of the fuel includes, a profile of ambient temperature while the fuel was stored in the vehicle. - View Dependent Claims (38, 39)
