ABSTRACT:
A main internal combustion engine powers a motor vehicle at 55 MPH. A smaller auxiliary engine powers the vehicle at slower speed. Both engines power at the same time for passing, hill climbing, etc. Either engine can be shut down (or idled) while the other engine powers. Thus, the engines operate more closely to best efficiency and this shall result in reduced fuel consumption (as calculated herein) and less air pollution.
In a first species, the main engine transmits shaft power through a standard friction clutch and then to an ordinary transaxle consisting of torque converter, automatic transmission and differential. The auxiliary engine is mounted next to the transmission. Power from the smaller engine passes through an overrunning clutch and then by toothed belt and sprockets to the torque converter.
A second species is identical to the first except an over running clutch takes the place of the friction clutch.
In a third species, the main engine, main clutch, and transaxle are standard items mounted in the same location as in present single engine cars.
