摘要： A fuel injection system for multi cylinder engine employs a plurality of separate computing circuits for generating variable width control pulses to fuel injectors. Each channel actuates at least one fuel injector during more than 50% of an engine cycle. To derive the start times for these four pulses, a counter is advanced in timed relation to the operation of the engine by pulses from the ignition primary circuit. To control the phase of the firing pulses relative to the cycle time of the engine the counter is reset once each engine cycle by a pulse derived from one of the spark plug leads.

摘要： The operation of an internal combustion engine is regulated by an electronic regulation circuit which utilizes suction pipe pressure to modulate the width of a pulsed signal and to vary the amplitude of a sawtooth wave signal in accordance with the duration of said pulsed signal so that the fuel injection to the engine may be controlled as desired under all operating conditions. The regulation circuitry includes apparatus for modifying the slope of the time versus pressure characteristic of the suction pipe transducer to account for the differences between full load and no load torque of the engine. This is accomplished byvarying the amplitude of the sawtooth waveforms by shunting a portion of the charging current to the sawtooth generator in accordance with the load conditions on the engine.

摘要： An intake throttle valve operating member is rendered movable independently of an intake throttle valve, disposed in an intake pipe, after the intake throttle valve has reached its maximum open position while holding the throttle valve in said maximum open position, and the amount of movement of the throttle valve operating member after the throttle valve has reached its maximum open position is transmitted to an electronic fuel injection control, unit, which in turn controls electrically the degree of opening of an electromagnetic fuel injection valve, whereby before the intake throttle valve reaches its maximum open position, the air fuel ratio can be adjustably maintained at a value at which the concentrations of the harmful components in the exhaust gas are low over the entire range of the internal pressure of the intake pipe, while after the throttle valve has reached its maximum open position, the amount of fuel only is increased to make the air fuel ratio smaller so as to obtain a greater torque.

摘要： In an internal combustion engine, the inductance of an inductive device is defined in direct relation to the intake pressure of the engine. Further, the inductive device is alternately charged through a first resistive device and discharged through a second resistive device at a trigger frequency which is defined in direct relation to the output speed of the engine. As a result, an action voltage of one polarity is developed as the inductive device is charged and a reaction voltage of opposite polarity is developed as the inductive device is discharged. Fuel is applied to the engine in an amount directly related to the duration of the action voltage as determined in direct relation to the time constant provided by the inductance of the inductive device and the resistance of the first resistive device and as determined in direct relation to the maximum peak of the action voltage. In turn, the maximum peak of the action voltage is inversely related to the minimum peak of the reaction voltage as determined in direct relation to the time constant provided by the inductance of the inductive device and the resistance of the second resistive device and as determined in direct relation to the trigger frequency. The resistances of the first and second resistive devices are selected so that the amount of fuel applied to the engine decreases with increasing output speed and increasing intake pressure after the output speed exceeds a predetermined speed limit.

摘要： Fuel is applied to an internal combustion engine for the duration of control pulses produced at a frequency proportional to the speed of the engine. The duration of the control pulses is determined as a function of the amplitude of a bias voltage. A speed voltage unidirectionally varies from a base level at the termination of each preceding control pulse to a peak amplitude at the initiation of each succeeding control pulse. A compensation voltage is substantially constant over the duration of each succeeding control pulse at an amplitude proportional to the peak amplitude of the speed voltage during each preceding cycle. The amplitude of the bias voltage is determined in response to the amplitude of the compensation voltage thereby to define the duration of the control pulses as a function of engine speed.

摘要： A circuit means is disclosed for aiding the collapse of an electromagnetic field in order to remove energy stored therein and thus to hasten movement of a movable member whose position is controlled by the strength of the electromagnetic field. In particular, an electronic device is used to provide a repeatable, uniform, rapid, controlled energy dissipating circuit path. By dissipating the energy stored in the electromagnetic field through a zener diode, uniformity of field collapse is assured, good repeatability is provided and actuation frequency of the field is increased.

摘要： Method and apparatus are disclosed for varying the width of a rectangular pulse which controls the opening of an electromagnetic fuel injector, in accordance with engine speed. Reference pulses of short duration are generated in synchronism with engine rotation and these pulses are utilized to generate injection pulses, and control pulses. The termination of the control pulse, which is of predetermined width, is utilized to generate a linearly increasing reference voltage which reaches a predetermined voltage level, depending on the spacing between the preceding reference pulse and the following reference pulse. The voltage level reached by the reference voltage is utilized to cut off the injection pulse. The width of the injection pulse, and in consequence the quantity of fuel injected, is thus directly controlled by engine speed, i.e., by the spacing of the reference pulses.

摘要： A fuel injection system for internal combustion engines wherein a transducer sends electric signals to an electronic control circuit which opens the fuel injection valves for intervals of variable length. The intensity of signals which the transducer transmits to the control circuit (and hence the length of intervals during which the valves inject fuel into the cylinders of the engine) is a function of two parameters, namely, the manifold pressure and the differential between manifold pressure and atmospheric pressure. The signals are produced by an inductance whose core is adjustable by a diaphragm and one or more evacuated containers as a function of the two parameters.
