    摘要: A fuel supply mechanism for an internal combustion engine includes a fuel-air mixture generator and an air bypass channel for conducting supplementary air to the mixture prior to delivery to the cylinders. The bypass channel has a valve which is coupled to the main throttle valve in the induction manifold. The coupling may be entirely mechanical or electro-mechanical. In addition, a controller which acts on the basis of engine information changes the degree of coupling between the main throttle and the bypass valve to admit more or less supplementary air, depending on the value of engine variables.

    摘要: The fuel mixture ratio of an internal combustion engine is adjusted by metering out a fuel quantity in relation to the air flow rate through the induction tube. The air flow rate is measured indirectly by monitoring the engine speed (rpm) with an electrical transducer driving a frequency-voltage converter, thus providing a first voltage, while a throttle plate position transducer generates a second voltage. The two voltages are applied to a logical circuit including parallel diodes which selects the lower of the applied signals and presents the resultant voltage as the primary control signal for fuel metering. Various compensating networks may be added to provide additional smoothing and adaptation to the operating characteristics of a particular engine and state of operation. Various fuel metering devices to be used in conjunction with the control circuit are also described.

    摘要: The induction manifold of an internal combustion engine is provided with an air bypass conduit which has an air flow metering valve which is controlled by the same differential pressure experienced by the air responsive element of the carburetor in the induction tube. The pressure drop across this valve is further influenced by a second air metering valve acting as a pressure control valve, also located in the bypass line downstream of the first metering valve. A regulator responsive to engine conditions controls valves which cause selective admission of different pressures to the actuation chamber of the pressure control valve to regulate the amount of bypassed air.

    摘要: The induction tube of an internal combustion engine is provided with a bypass conduit which feeds additional fresh air to the induction tube downstream of the carburetor and the main throttle plate. The flow through the bypass is controlled by a pneumatic control valve which is actuated by selective admission of a mixture of pressures taken from the main induction tube and from ambient sources. The selection takes place on the basis of transducer signals related to engine conditions which are processed by a regulator.

    摘要: A fuel control system for an internal combustion engine in which the accelerator pedal is set by the operator and defines an air flow control variable which is applied to a control loop that actuates a servo motor or other suitable rotary means to set the relative position of an air flow control flap within the induction tube. The control loop attempts to maintain the position of the air flow flap in continuous correspondence with the accelerator pedal position. The actuating current for the final control element is used as one input datum for a stored data field. Another input variable to the data field is the actual position of the air flow valve or flap. The data field contains empirically obtained data relating these two variables with the prevailing air flow rate and generates an output signal that is used as the air flow rate signal in a control pulse generator. The control pulse generator also receives other signals related, for example, to temperature, engine speed, etc. From this set of signals, the generator produces a fuel admission control signal, for example a fuel injection control pulse. The system includes special circuits for applying, for example, an engine idling correction signal to the control loop when the engine speed falls below a certain predetermined value.

    摘要: A method and apparatus for improving the acceleration behavior of a self-igniting internal combustion engine driven with an exhaust turbocharger by displacing the onset of injection during the acceleration phase toward "early", and a combustion chamber pressure is attained, which at least in part compensates for reduction in engine power caused by sluggishness of the turbocharger and a resultant smaller cylinder charge. Further increase in power is attained by means of an increase in the fuel component made possible by the adjustment of injection onset without exceeding the smoke limit of combustion. Apparatus are furthermore proposed for performing the method according to the invention, in which with the aid of an acceleration signal obtained by hydraulic or electric elements an adjustment toward "early" is effected in a hydraulically functioning injection adjustment device.
