概要

A description is made of a new control system for a two-shaft type, regenerative gas turbine engine intended for use in automobiles. The system simultaneously controls engine operation and the transmission, and has several unique features: control algorithms have been specially devised to regulate the fuel flow rate without using turbine outlet temperature as feedback and to compensate for back-lash when adjusting the piston position of the actuator controlling the variable nozzles, while a new circuit has been added to control the forward clutch. As a result of these techniques, maximum turbine inlet temperature is quickly attained, nozzle opening area is optimized according to operating conditions and practical use is made of inertia energy. By these means, the characteristic "turbo-lag" is minimized and vehicle acceleration performance-both from standstill and from steady speeds-is improved for greater safety as well as each of driving.
