Hybrid power system

DETAILED DESCRIPTION What we claim is: 1.
A parallel hybrid power system comprising combustion engine means having air/fuel mixture intake means, an exhaust port for the exhaust of burned gases, and a drive shaft; battery means; a dynamotor having a shaft coupled by a fixed mechanical ratio to said drive shaft, armature winding means coupled to said battery means, and field-winding means, said dynamotor being selectively operable to draw power from said battery means to aid said engine means in the turning of said drive shaft and for drawing power from said drive shaft to recharge said battery means; speed control means coupled to said dynamotor field-winding means for varying the current flow therein; means for controlling the intake of air/fuel mixture by said engine means such that the ratio of exhaust of said engine means to the drive shaft speed remains substantially constant during normal operation of the power system as the current flow in said field-winding means is varied; thermal reactor means; means for directing the exhaust from said engine means to said thermal reactor means; and means coupled to and operated by said drive shaft for directing secondary air to said thermal reactor means at a rate which is directly proportional to the speed of said drive shaft.
2.
A parallel hybrid power system in accordance with claim 1 further including means for varying the ratio of air to fuel in the air/fuel mixture taken in by said engine means, means for measuring the temperature of the burning gases in said thermal reactor means, and means for controlling the operation of said air to fuel ratio varying means to maintain a substantially constant temperature of the burning gases in said thermal reactor means.
3.
A parallel hybrid power system in accordance with claim 2 wherein the operation of said intake controlling means is independent of the operation of said speed control means.
4.
A parallel hydrid power system in accordance with claim 3 wherein said air/fuel mixture intake means includes an intake manifold and a carburetor having throttle means for adjusting the vacuum in said intake manifold, and said intake controlling means includes feedback means for detecting changes in the manifold vacuum from a predetermined value and means for positioning said throttle means such that the manifold vacuum is returned to said predetermined value
