    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: 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.

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: A method of controlling fuel mixture supply to an internal combustion engine having fuel injection system in which the quantity of fuel is metered in dependency on gas pedal position and the quantity of air is subsequently metered in dependency on the position of the throttling plate. The method employs a preliminary control with superposed extreme value regulation. For this purpose, the injection time interval or the throttle plate position are adjusted in dependency on the gas pedal position and on the rotary speed of the engine. During the operation of the engine, test cycles are continuously established and according to the reaction of the engine to the tests, the adjustment of the injection time interval and of the throttle plate position are made. The method is suitable particularly for internal combustion engine used in motor vehicles.

    摘要: A method is proposed for monitoring operations of an internal combustion engine to detect combustion misses for internal combustion engines having dual spark coils. A method is provided for the primary-side monitoring of the spark voltage and/or of the spark duration, and a method is provided for detecting irregular operations. If a faulty ignition is detected in one cylinder at one spark plug by monitoring the spark voltage and/or the spark duration, the second spark plug in this cylinder is then cut off (de-energized) and the reaction to this cut-off is monitored by means of the method for detecting irregular running. If the irregular running detection confirms faulty operation of the internal combustion engine, then the faulty ignition at the first spark plug of a cylinder was correctly recognized and appropriate emergency measures are introduced.

    摘要: In the operation of an internal combustion engine, certain operating parameters, for example the length of fuel injection pulses, the ignition timing and the exhaust gas recycle rate can be adjusted on the basis of information related to state variables of the engine, for example the engine speed, the induction tube pressure, the air flow rate and the like. In particular, the injection pulse length may be determined from data stored in a memory and addressed by a pair of numbers related to the instantaneous values of engine speed and air flow rate. This type of open loop control is rapid and may be very exact but does not account for long-range changes in engine behavior due to wear, etc. For this reason, additional circuitry senses a further state variable, for example, the oxygen content of the exhaust gas or the engine roughness, and uses this information in a feedback loop to generate a correction signal which is then applied in a rate multiplier to the basic fuel injection datum. The closed loop control is effective only in certain operational domains which are indicated by load-related conditions, e.g., the throttle valve opening.

    摘要: Clock pulses are multiplied by a ratio less than 1 of which the numerator is controlled by a reversible counter. The multiplier output pulses initiate new countdown cycles of a second counter beginning with the clock pulse following the onset of an input frequency pulse and ending with the clock pulse following the onset of the next input frequency pulse. The state of the count at the end of the cycle determines whether the reversible counter will be left unchanged, advanced, or counted back and hence, whether the multiplier output frequency will be left unchanged, increased or reduced. The initial countdown value of the second counter is provided by a long term store which determines the frequency multiplication ratio. The circuit is usable to multiply a variable input frequency in a vehicle brake anti-lock system.
