    摘要： An apparatus is disclosed for venting a fuel tank of internal combustion engines or the like, wherein fuel vapors developing in the tank are received in an intermediate storage unit containing an activated carbon filter and are delivered to the induction area of the engine in dependence upon operating conditions. The delivery is accomplished by an electrically controlled tank venting valve having a pass-through opening the cross section of which is continuously changed. This is achieved by changing the pulse duty factor of the drive pulse train for this valve. The pulse duty factor may be determined in the sense of a pure control using a family of characteristic fields in dependence on rotational speed and load of the engine, or by taking into account preferably averaged Lambda values with a reduction in the cross section of the pass-through opening of the tank vent valve as the mixture becomes richer. Further, an adaptive anticipatory control is provided which enters into the calculation of the fuel quantity to be supplied or of the fuel injection signal with a correction value (ATE) and switches over to a limit control when predetermined mixture proportions are reached. The basic adaptation in the Lambda control system for calculating the fuel supply is released only if the fuel quantities originating from tank venting are negligible.

    摘要： The invention is directed to a method for controlling the lambda value of the air/fuel mixture supplied to an internal combustion engine. The method utilizes the signal of a lambda probe as the measurement of an actual value with this actual value displaying discontinuities during the transistion from the rich to the lean lambda region. The switch-over of the control direction in the direction "rich" is undertaken when the actual value in the form of the probe voltage passes through the reference voltage; however, this only happens when the probe voltage had an previously climbed to a threshold value "rich". Correspondingly, the control direction is swiched over to the direction "lean" only when the reference value is passed through and when the probe voltage previously had dropped to a threshold voltage "lean". The apparatus which operates pursusant to the method no longer leads to undefined control oscillations when cylinder scatter effects occur.

    摘要： Fluctuations of engine speed in the frequency range from 2 to 8 Hz, which produce "bucking" behavior of a motor vehicle, are detected by passing engine speed signals through a filter which reduces and delays the oscillations and a difference signal is then produced between the original and the processed speed signal in order to derive an alternating signal in the form of a square wave indicating the sign of a correction to be made to engine ignition timing for counteracting the bucking oscillations of engine speed. The square wave determines the sign of an anti-bucking ignition timing correction factor, of which the absolute value may be constant or may vary according to the sign of the correction and, if desired, also in accordance with engine operation parameters.

    摘要： The engine for which the system provides ignition control produces a basic signal giving the time lapse of a predetermined angle of crankshaft rotation. Leading and trailing edges of this basic signal produce control signals. During the interval between these two a first counter stepped by clock pulses produces a count proportional to engine speed down to a certain relatively low engine speed beyond which overflow of the counter holds the counter at its maximum value. The count so determined is utilized in an ROM as the engine speed parameter which together with other engine operation parameters produce the address that selects the appropriate number to control computed ignition timing. According to the engine speed range, a second counter is loaded either with the number provided by the ROM, or with a count number based on engine speed only and the second counter then counts down past thresholds provided by a second ROM to determine both the moment of closure of the electronic switch and the moment of opening. The closure interval is generally maintained constant, consistently so at low speeds, but at high speeds a minimum open interval of the electronic switch in the primary circuit of the ignition transformer overrides this requirement. In certain embodiments ignition timing is provided by the reaching of a threshold value of current in the primary winding, under certain limited conditions.

    摘要： To permit operation of engines, particularly turbo-charged engines, at the maximum power level just short of causing engine knocking, and preventing engine knocking, temperatures in the engine are sensed and, if an excessive temperature signal is detected, for example excessive engine temperature, exhaust gas temperature, turbo-charged air, or turbo charger temperature, a fuel supply system, for example a fuel injection system, is controlled to enrich the mixture, for example by multiplying the fuel injection time by a factor as commanded by an additional control stage (26, 27, 30) which stores in a memory, such as a ROM (27), engine operating characteristic curves. In addition, spark retardation by a retarding angle (.alpha.1) can be commanded, the spark retardation in combination with enriching of the fuel-air mixture being less than without such enrichment, thus permitting operation of the engine at appropriate power and efficiency level without noticeably increasing fuel consumption in the course of continued operation of the engine.

    摘要： A method is proposed for self-monitoring of microcomputer-controlled network devices (10) in motor vehicles which in accordance with applied transducer signals execute specified functions and upon detecting an error store a corresponding data word in memory. For indicating the error, the data word is converted into a signal train or voltage and detected by means of voltage measurement. This is preferably accomplished by inserting a diagnosis insert-plug (42) between the transducer lines and the network device (10). A voltmeter (47) can be connected to this test adapter and indicates this signal train or voltage. A specific type of error is associated with a specific voltage. As a result, a diagnosis which is as detailed as desired, of a complicated system, can be performed with a simple voltmeter (47) available in commerce.
