Abstract
1512213 Automatic control of IC engines ROBERT BOSCH GmbH 13 May 1975 [19 Oct 1974] 19993/75 Heading G3R The fuel/air ratio and/or the rate of feedback of exhaust gas in an I.C. engine is controlled in response to an electrical measurement of fluctuations in an operating parameter of the engine, the measurement beingmade by a pick-up 17 connected to an alternating voltage amplifier 21 whose output is compared at 25 with a desired value. The desired value is generated at 26, and may be varied in response to the absolute value of the parameter measured by the pick-up and/or the induction pipe pressure and speed. As shown the parameter is cylinder pressure, measured at 17 and amplified at 19, but it may alternatively be peak voltage at a sparking plug, integrated ion current or flame propagation time (measured as the time between threshold values of the voltage at the sparking plug and ion current at a probe spaced from the plug). In all cases the measurement is switched at engine speed by a transister 20 and pulse generator 28 to a capacitor 40 connected to an operational amplifier 22 whose output thus represents changes in the measured parameter between successive cycles. It is explained that these are a function of combustion mixture and the desired value may be chosen so that the fluctuations are high, due to a lean mixture. The comparator 25 switches a bi-stable circuit 32 when the measured fluctuations exceed the reference; the bi-stable then resets an integrator circuit 34 which otherwise integrates a constant voltage so as to progressively weaken the mixture.
