摘要： A method for determining adjustment values for a fuel supply device which supplies a fuel mixture to a fuel-burning engine for optimum performance by additionally influencing the preset adjustment values of the fuel supply device itself from values supplied by a storage means containing an engine performance log of adjustment values whereby said performance adjustment values are continuously changed and replaced by values which reflect instantaneous operating engine characteristics. Each replaced value forms the basis for computing a new value upon a change in engine operating characteristics. The apparatus disclosed comprises a fuel supply device, such as a carburetor, which has its adjustment values preset due to its construction, a storage means containing engine performance adjustment values for correcting the preset values of the supply device in response to engine operating characteristics, and a second storage means connected to the fuel supply device and to the first storage means wherein the performance values from said first storage means are continuously adjusted from the engine operating characteristics and stored for use by the fuel supply device for optimum engine operating performance.

摘要： A principal operational variable of an internal combustion engine, for example the fuel-air mixture ratio, is controlled by superposition of three separate control steps. The basic setting of a control variable is obtained with a relatively coarse forward control, for example a carburetor in the case of fuel-air mixture control. Superimposed on this basic control is a refined forward control step which is based on the prevailing magnitudes of at least one operational variable, preferably the engine speed and the throttle valve position, and which applies a multiplicative correction to the basic setting of the fuel-air mixture. The third superimposed control step is a feedback control of the fuel-air mixture within the range of correction applied by the second control steps but based on still another engine variable, in particular the exhaust gas composition as sensed by an oxygen sensor (.lambda.-sensor). After comparison with the reference signal, the .lambda.-sensor signal is multiplied with the sum of the values of the basic air factor setting and the first corrective air factor setting. The data required for applying the first correction are preferably stored in a digital memory.

摘要： To supervise operational effectiveness of catalytic reactors included in exhaust emission detoxification systems, an oxygen sensor is located downstream of the reactor to determine oxygen content in the exhaust gases from the internal combustion engine, the oxygen sensor comprising an ion conductive solid electrolyte forming an ion concentration chain and having catalytically inactive contacts, connected to a detection circuit which provides an output signal in dependence on a signal from the sensor, the output signal operating an alarm, or a transducer which interferes with proper engine operation to force the operator to have the reactor repaired. Preferably, two ion conductive chains are used, in a single sensor, or in two sensors, one being exposed to exhaust gases upstream of the catalytic reactor and the other downstream of the catalytic reactor, the output signals being provided to a differentially connected operational amplifier, to balance out extraneous influences.

摘要： The invention is directed to an apparatus and a method for controlling the operating characteristic quantities of an internal combustion engine, with a characteristic set up with operating quantities of the internal combustion engine for pre-control of engine variables influencing the operating characteristic quantities, and with a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic values. The values stored in the characteristic field and selected in dependence on operating characteristic quantities of the internal combustion engine are modified via the control arrangement to correctively influence the characteristic values. In addition, the characteristic values lying within the defined region of the characteristic value modified are also changed in dependence on the modification of this particular characteristic value. The fact that the modification of a characteristic region in dependence on the modification of its respective characteristic value is weighted, permits a rapid and accurate adaptation of the characteristic to the actual operating conditions of the internal combustion engine. The invention is advantageously suitable for use in various control systems contolling air-fuel metering, ignition point, charge-air pressure, exhaust-gas recirculation of idle speed, for example.

摘要： The invention is directed to an apparatus for controlling the operating characteristic quantities of an internal combustion engine. The apparatus includes a characteristic field for pre-controlling engine variables influencing the operating characteristic quantities. The characteristic field is made up of the operating characteristic quantities. The apparatus further includes a control arrangement for controlling to maximum power output of the engine.

With the apparatus of the invention, it is possible in a simple manner to consider changes in the surrounding factors that influence the engine. Two embodiments are described wherein the control is achieved by means of an optimizer and the engine is controlled to maximum power in either the part-load range or the full-load range of the engine. The apparatus of the invention can be used, for example, in air-fuel mixture metering, charging air control, control of exhaust gas return or also idle control.

摘要： The invention is directed to an apparatus for metering an air-fuel mixture to an internal combustion engine with an extreme-value control arrangement for controlling to a minimal specific consumption of fuel. The extreme-value control arrangement includes a test signal generator for acting upon the fuel metered to the engine. The rotational speed and a fuel metering signal are applied by the extreme-value control arrangement as actual information with respect to the minimal specific fuel consumption. In particular, the quantities of rotational speed change and the change in duration of fuel injection are utilized to determine the minimal consumption in the case of an internal combustion engine equipped with fuel injection. Further, for a minimal consumption control, it has been shown to be advantageous to consider information as to which gear of the transmission of the engine is in place.

摘要： Certain intervals are determined in which output signals from an exhaust gas sensing device are sensed, and then applied to a control circuit, to control the fuel supply system (carburetor, or fuel injection system) in such a direction that a predetermined ratio of fuel and air is being supplied to the engine to provide exhaust gases of predetermined composition. The intervals are determined by a logic circuit which has applied thereto engine operating parameters such as operating time of the engine after having been started, engine speed, engine power condition (idling, or supplying power), engine temperature, or the like.

摘要： The invention is directed to an apparatus for metering an air-fuel mixture to an internal combustion engine. The apparatus includes a characteristic field set up with operating quantities of the internal combustion engine for anticipatorily controlling engine variables that influence the air-fuel mixture and a control arrangement, responsive to at least one engine variable, for correctively influencing the characteristic field values. The characteristic field values are stored in the characteristic field and selected in dependence on operating quantities of the internal combustion engine. The characteristic field values are modified by means of different control methods to correctively influence the same. More specifically, the control methods include a control to a minimal specific fuel consumption in the lower and part-load ranges as well as a control to maximum power in the upper load range as may be necessary. This control arrangement can be realized, on the one hand, with an extreme-value control which is superposed either on the air or quantity of fuel delivered to the motor or, on the other hand, with a direct control of the air ratio .lambda. with an exhaust gas probe, for example. With the apparatus of the invention, a minimal specific fuel consumption with reduced exhaust gas emissions are realized while at the same time ensuring a satisfying driving behavior of the vehicle.
