ABSTRACT:
For a vehicle equipped with a pair of driving engines and a torque converter having a capacity sufficient to absorb the combined peak torque of the engines at combined peak torque speed, a dual engine drive including a planetary gear set operative to provide direct drive between the engines and the torque converter when both engines are operating and to provide gear reduction between the engines and the torque converter when only one engine is operating. The gear ratio of the planetary set is preselected to reduce the input speed to the torque converter while increasing the input torque to the torque converter so that the output of the one remaining engine is more efficiently matched to the torque converter.
