ABSTRACT:
To permit use of a manual transmission with the advantage of positive drive and hence better fuel economy with a controlled clutch (14), for example under operator control (13) or gear selection control (2013), an engine fuel control positioning stage (11) is provided which receives, upon start of the vehicle and change of the transmission from neutral to first gear, an engine starting speed reference signal from an engine speed controller (19). The clutch, under operator or gear change control, has a disengagement path (15) which causes rapid disengagement of the clutch and a connection or reengagement path (16) which operates with time delay to cause gradual engagement of the clutch so that smooth start-up is insured. A suitable start-up speed is idle speed of the engine, or close thereto.
