Abstract

PURPOSE: To cause velocity ratio automatic control of an infinitely variable gear for a car to rapidly follow the speed change ratio control for variation of the engine load, by ejected fuel amounts proportional to engine torque.
CONSTITUTION: A diesel engine DE equipped with a fuel ejection pump EIP is connected through a fly-wheel 1 to an input shaft 2 of an infinitely vatiable gear or mechanical-hydraulic infinitely variable gear H, and the input shaft 2 is provided with a hydraulic pump P which applies a certain line pressure to an oil passage P2 by action of a releaf valve PV and a valve G1 by which the line pressure is adjusted to a hydraulic pressure corresponding to the rotational speed of an engine E and is supplied to an oil passage P7. The fuel control rack position of the fuel ejection pump is detected, it is compared with an aimed value, and the difference, i.e. a speed proportion control signal, controls the velocity ratio of the mechanical- hydrauric adjuster H.
