Abstract

1337448 Electronic fuel metering systems ROBERT BOSCH GmbH 19 April 1971 [26 March 1970 5 Feb 1971] 25333/71 Heading G1N In an electronically controlled I. C. engine fuel system, a function generator is arranged to control the metering of fuel in dependence upon engine operating parameters so that predetermined values of excess-air coefficient #, (i.e. a measure of the fuel/air ratio), are achieved. The system can then be arranged so that below a certain speed a weak mixture is provided to produce minimum exhaust of unburnt gases and above this speed a rich mixture is provided for optional engine performance. As shown in Fig. 3, a function generator 19 controls the metering of fuel in dependence upon signals from an accelerator angle sensor 14 e.g. a potentiometer, a rate of air-flow sensor 15, 16 or 15a, 16a and a speed sensor 18, e.g. a multi-vibrator. Sensor 15, 16 is a heated temperature responsive resistor mounted in a bridge circuit, Fig. 3a (not shown), and sensor 15a, 16a is an aperture plate connected to the wiper of a potentiometer, Fig. 3b (not shown). To further reduce the amount of unburnt gases being exhausted, the position of the air throttle may be additionally controlled, Figs. 4 - 4c (not shown), the ignition timing and spark duration may be additionally controlled, Figs. 5- 9 (not shown), and the injection timing (if the system is an injection system), and the recirculation of the unburnt gases may be additionally controlled, Fig. 10 (not shown). Other engine parameters which may be utilized in the control are air temperature and pressure, water temperature, and amount of unburnt gases.
