Abstract
Abstract The disclosed hybrid power train for a self-propelled vehicle is designed to reduce the emission of atmospheric pollutants. The chemically fueled prime mover and the secondary-battery powered electric dynamotor are joined together and joined to the output shaft by fixed ratio rotating linkage. The prime mover is operated as a quasi-constant -torque device, with its torque able to be varied in response to the state of charge of the battery or to operator torque demands in excess of certain predetermined amounts. The instantaneous torque output of the combined combustion engine/electric motor power train is controlled by a mechanical accelerator control which causes the dynamotor to either add to or subtract from the torque produced by the prime mover. When added torque is required by the vehicle, the dynamotor takes energy from the storage battery. When less torque is required, the extra energy produced by the prime mover is fed by the dynamotor into the storage battery. The low pollution qualities of this power train are realized, in part, by the uncoupling of the prime mover throttle from the rapid variations of the accelerator control typical of urban driving.
