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： 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： An internal combustion engine which is provided with an exhaust gas treatment system, such as thermal or catalytic reactors, includes a primary regulating system for admitting fresh air to the exhaust system for the chemical processes taking place in the reactors. This fresh air regulation depends on the engine rpm and on the induction tube pressure. There is also provided a secondary air control system, including a three-way valve and an electronic controller and an oxygen probe, located in the exhaust manifold. The probe supplies the controller with a signal related to the oxygen concentration in the exhaust gas and the controller uses this signal to actuate the three-way valve which admits either induction tube pressure or, alternatively, exhaust system pressure, to a control chamber in the primary regulating system, thereby influencing the quantity of fresh air supplied to the exhaust manifold of the engine.

摘要： The inlet and outlet ends of a catalytic reactor are instrumented with oxygen sensors. A change of the fuel-air concentration of the combustible mixture is indicated by a jump in the output voltage of the sensors; the voltage of the inlet sensor changes before that of the outlet sensor and the greater the time difference between these changes, the higher is the catalytic activity of the reactor. When a repeatable and constant engine condition is reached, the fuel-air mixture is abruptly changed and an electronic circuit enables a logical circuit which controls a signal lamp. If, during a predetermined time interval, the outlet sensor also changes its output voltage, indicating a time difference which is too short, the warning signal is energized and the operator is alerted to the insufficient level of reactor activity.

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.

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.
