Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A system for starting an internal combustion engine, comprising: an electrical energy storage device; a cranking motor connected with said storage device; an electrically powered fuel heater for warming fuel flowing to an engine, with the fuel heater being powered by said electrical energy storage device; and energy management means for estimating the energy delivery capability of said storage device as a function of at least one variable having a value determined during a previous episode of engine operation with said energy management means further comprising means for determining the amount of time during which said fuel heater should be operated, based upon at least one sensed temperature, and means for notifying the operator of the engine in the event that the estimated energy delivery capability of the energy storage device is not sufficient to operate said fuel heater for the desired time interval.
Claim 2
Independent Claim
144 words
A system for starting an internal combustion engine, comprising: an electrical energy storage device; a cranking motor connected with said storage device; an electrically powered fuel heater for warming fuel flowing to an engine, with the fuel heater being powered by said electrical energy storage device; and energy management means for estimating the energy delivery capability of said storage device as a function of at least one variable having a value determined during a previous episode of engine operation with said energy management means further comprising means for determining the amount of time during which said fuel heater should be operated, based upon at least one sensed temperature, and means for notifying the operator of the engine in the event that the estimated energy delivery capability of the energy storage device is not sufficient to operate said fuel heater for the desired time interval.
Claim 3
Independent Claim
143 words
A system for starting an internal combustion engine, comprising: an electrical energy storage device; a cranking motor connected with said storage device; an electrically powered induction air heater for warming air flowing into the cylinders of an engine, with said air heater being powered by said electrical energy storage device; and energy management means for estimating the energy delivery capability of said storage device as a function of at least one variable having a value determined during a previous episode of engine operation with said energy management means further comprising means for determining the amount of time during which said air heater should be operated, based upon at least one sensed temperature, and means for notifying the operator of the engine in the event that the energy delivery capability of the energy storage device is not sufficient to operate said induction air heater.
