摘要： A fuel supply and metering valve assembly used for injection of fuel to an internal combustion engine includes a control pressure circuit which determines the restoring force on the movable member of the fuel metering valve. The magnitude of the control pressure, and hence the fuel quantity metered out by the valve assembly can be altered by the intermittent actuation of a pressure relief valve which controls a fluid bypass. The duty cycle of the intermittently acting bypass valve is controlled by a regulating device which responds to the indications of measuring transducers, for example an oxygen probe located in the exhaust line of the engine. The transducer signal is superimposed on a sawtooth voltage at the input of a differential amplifier which interacts with other control circuitry so as to vary the length of time during which the electromagnetic bypass valve is energized.

摘要： A fuel injection system for externally ignited internal combustion engines preferably has one fuel injection location in the air induction tube (manifold). The metering of fuel occurs independently of the condition of the air prevailing at the injection location, the injection location is disposed ahead of the junction of the air induction tube which leads to the individual engine cylinders. Air is brought to a high velocity by means within the induction tube and impinges, at this high velocity, immediately on the injected fuel, enveloping the same. As a result, the mixture preparation is effected without wetting of the inner wall of the induction tube and the means which bring the air to the required high velocity.

摘要： The airflow rate through the induction tube of an internal combustion engine is measured by a first transducer which delivers a set point signal to a control amplifier. The amplifier also receives a feedback signal from a second transducer which monitors the position of a servo-motor controlling the quantity of fuel metered out to the engine. The feedback loop maintains a desired fuel-air ratio and includes provision for calibration and adjustment.
