Abstract
Abstract This invention relates to the use of the exhaust of an internal combustion engine to contribute to forward motion by a pneumatic device connected directly to the drive train and a motor generator connected to the drive train to contribute to acceleration and to provide regenerative braking. All of the automobiles electrical needs are supplied by recaptured momentum when driving conditions allow. Surplus electricity is stored to further contribute to acceleration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A propulsion system for a vehicle having an internal combustion engine, drive wheels and a transmission comprising a direct current motor generator connected between the engine and transmission to add power to the internal combustion engine, a first clutch between said transmission and said motor generator, adapted to disengage the transmission while the engine is running so that the engine can turn the motor generator with the vehicle at rest, a second clutch between said engine and said motor generator, adapted to disengage the engine for regenerative braking or purely electrical operation, and means to achieve continuous variable speed control of said vehicle comprising utilizing a direct current motor generator controlled by selecting different armature windings selected by placing a tapped armature on the stator with a permanent magnet as the rotor.
Claim 2
Dependent Claim
132 words
A propulsion system for a vehicle having an internal combustion engine, drive wheels and a transmission comprising a direct current motor generator connected between the engine and transmission to add power to the internal combustion engine, a first clutch between said transmission and said motor generator, adapted to disengage the transmission while the engine is running so that the engine can turn the motor generator with the vehicle at rest, a second clutch between said engine and said motor generator, adapted to disengage the engine for regenerative braking or purely electrical operation, and means to achieve continuous variable speed control of said vehicle comprising utilizing a direct current motor generator controlled by selecting different armature windings selected by placing a tapped armature on the stator with a permanent magnet as the rotor.
Claim 3
Independent Claim
21 words
The device of claims 1 further comprising an exhaust gas driven generator adapted to provide power to said direct current motor.
Claim 4
Dependent Claim
187 words
A propulsion system for a vehicle having an internal combustion engine, drive wheels and a transmission comprising a direct current motor generator connected between the engine and transmission to add power to the internal combustion engine, a first clutch between said transmission and said motor generator, adapted to disengage the transmission while the engine is running so that the engine can turn the motor generator with the vehicle at rest, a second clutch between said engine and said motor generator, adapted to disengage the engine for regenerative braking or purely electrical operation, and means to achieve continuous variable speed control of said vehicle comprising a continuously variable transmission coupled directly between the direct current motor generator and the drive wheels, wherein the internal combustion engine has pistons, a plurality of the pistons having three associated valves, a first valve for intake, a second valve for exhaust and a third valve adapted to open only near the bottom of the power stroke of the associated piston, to supply exhaust gasses to an exhaust gas driven generator that is adapted to provide power to said direct current motor generator.
Claim 5
Dependent Claim
187 words
A propulsion system for a vehicle having an internal combustion engine, drive wheels and a transmission comprising a direct current motor generator connected between the engine and transmission to add power to the internal combustion engine, a first clutch between said transmission and said motor generator, adapted to disengage the transmission while the engine is running so that the engine can turn the motor generator with the vehicle at rest, a second clutch between said engine and said motor generator, adapted to disengage the engine for regenerative braking or purely electrical operation, and means to achieve continuous variable speed control of said vehicle comprising a continuously variable transmission coupled directly between the direct current motor generator and the drive wheels, wherein the internal combustion engine has pistons, a plurality of the pistons having three associated valves, a first valve for intake, a second valve for exhaust and a third valve adapted to open only near the bottom of the power stroke of the associated piston, to supply exhaust gasses to an exhaust gas driven generator that is adapted to provide power to said direct current motor generator.
Claim 6
Dependent Claim
37 words
The device of claim 3 wherein the exhaust gasses exiting through said third valve are passed directly through the intake valve of another piston connected directly to the drive train and driven solely by said exhaust gasses.
Claim 7
Dependent Claim
38 words
The device of claim 1 in which said vehicle includes a water pump, fan and oil pump, means to electrically operate the water pump, fan, and oil pump of the vehicle using the power output of said generator.
Claim 8
Independent Claim
22 words
The device of claims 3 or 1 wherein the motor generator also acts as the starter motor for said internal combustion engine.
Claim 9
Independent Claim
22 words
The device of claims 3 or 1 wherein the internal combustion engine cooling system heat is utilized to preheat the air-fuel mixture.
