Abstract
1281090 Automatic control of speed ROBERT BOSCH GmbH 27 Oct 1969 [25 Oct 1968 (2) 7 Nov 1968] 52462/69 Heading G3R An electronic governor for an internalcombustion engine, e.g. a diesel, comprises a regulator having an operational amplifier 27 having non-inverting and inverting input terminals, to the latter of which is connected an engine speed signal and a feedback network R which determines the governor characteristics. As shown, a speed reference voltage from a pedal operated potentiometer is applied to the non-inverting input 29 and a voltage from a tachogenerator is applied to a speed input 33. The tachogenerator may produce pulses or an A. C. signal whose frequency is proportional to speed, and this is converted to a D.C. voltage by an RC circuit Figs. 2 and 3 (not shown). In the feedback network shown a capacitor 36 provides a differential component and a potentiometer 38 controls the slope of the speed/fuel supply characteristic. The output of 27 controls the fuel injector by an electrohydraulic system of an electric servomotor, and injector position feedback is provided. A number of alternative embodiments are described Figs. 7... 20 (not shown) for operating governors which control speed throughout the range and/ or the idling and maximum speed characteristics only and include arrangements for producing non- linear features such as a kink in the idling characteristic. This is produced by a diode circuit whose conduction is determined by an adjustable resistor network Fig. 7 (not shown) or an auxiliary voltage source, Fig. 10 (not shown). Also positive feedback may be used to produce a positive slope to the load limiting characteristic, Fig. 11 (not shown) and a further diode circuit used for temperature compensation, Fig. 17 (not shown). In Figs. 21 to 32 (not shown) separate amplifiers are connected in parallel with the main amplifier to produce the required characteristics, and these are further modified by various transistor circuits between the tachogenerator and the amplifier input.
