摘要： A fuel-injection arrangement for internal combustion engines with electromagnetically actuated fuel-injection valves and intake manifold. A monostable multivibrator provides output pulses having a duration dependent on at least one operating parameter of the engine, such as the suction pressure within the manifold behind the throttle valve. A pulse-extending stage connected to the monostable multivibrator emits an extending pulse adjoining each pulse from the multivibrator and having a duration which depends on the duration of the preceding pulse from the multivibrator. A second monostable multivibrator has an unstable state duration beginning with the extending pulse and lasting for a fraction of the duration of the extending pulse. A compensating network connected to the pulse-extending stage influences the duration of the extending pulse by either increasing or decreasing the duration of the extending pulse.

摘要： A fuel injection system in which fuel flow through the injector nozzles is controlled by electrically operable interrupter valves. Electrical pulses to operate the interrupter valves are generated at constant frequency and the length of the pulses is varied with an engine operating parameter, for example engine air intake. Suitable pulse generating circuits and an arrangement for varying the pulse length with air intake are described.

摘要： An AND circuit, controlled by an engine-rpm-dependent bistable multivibrator, triggers a monostable circuit that produces a pulse having a length dependent on the intake-manifold-suction pressure. This pulse partly controls a logic circuit also controlled by the output of the multivibrator. The logic circuit, in turn, controls an amplifier the output of which operates the fuel injection spray valves.

摘要： Electronically controlled injector arrangements. An arrangement for adjusting the duration of injection into the cylinders of an internal combustion engine by means of signals produced by a bistable flip-flop controlled by the rotation of the engine, said signals defining the beginning and the end of the successive injections. The adjustment of the duration of injection is provided by delay means including a relaxation oscillator, the pulses produced by which are transformed into a train of rectangular high-frequency signals the duration of which is controlled by a main parameter governing the operation of the engine. These signals are then integrated and when a predetermined amplitude is reached, as defined by other parameters governing the operation of the engine, the end-ofinjection signal is generated.

摘要： An arrangement by which corrections are applied to the pulses which open electromagnetically controlled valves for fuel injection in internal combustion engines. The opening pulses for the valves are generated by a monostable multivibrator to which a control voltage is applied. The multivibrator emits substantially rectangular-shaped pulses, the durations of which are controlled as a function of speed of the engine, through the control voltage. The control voltage has characteristics variable periodically in synchronism with the pulses provided by the monostable multivibrator. A storage capacitor integrates the control voltage, and charging sources connected to the capacitor have different internal resistances. The charging sources are switched and connected to the capacitor in predetermined sequence.
