摘要： An arrangement for lambda control operates on an internal combustion engine (11) comprising a catalytic converter (12) and a lambda probe (13.v) mounted in front of the catalytic converter and a lambda probe (13.h) mounted behind the catalytic converter. The arrangement integrates by means of an integration means (15) the difference between the actual lambda value measured by the rear probe and the lambda desired value to which controlling is to be effected. The integration value is used as control desired value for a means (16) for lambda control. This arrangement and the associated method make it possible to control to the actually wanted lambda desired value even if the front lambda probe carries out incorrect measurements, for example because of hydrocarbons in the exhaust gas in front of the catalytic converter or, in the case of continuous-action control, faulty linearization of the probe characteristic.

摘要： A control system for controlling the air/fuel ratio in an internal combustion engine 10, in which an oxygen probe (lambda probe) 13 is arranged in the exhaust gas of the internal combustion engine 10, has a control device 12 for continuous control. The actual value of the air ratio lambda is determined via a measured probe output voltage in conjunction with an at least approximately predetermined probe-characteristic relationship 16 between the value of the probe output voltage and the value of the air ratio lambda associated therewith. After forming the difference of desired value and actual value of the air ratio lambda, the air/fuel ratio is controlled on the basis of this difference. Such a control system is used primarily in order to reduce the total emission of the main pollutant components of the exhaust gas of an internal combustion engine. In particular in the case of an internal combustion engine 10 with catalytic converter arranged in the exhaust gas, a maintenance of the air ratio lambda as accurate as possible necessary for optimum efficiency of the catalytic converter (lambda=1) is assured.

摘要： The invention is directed to a method for lambda control of an internal combustion engine having a catalyzer and a measuring probe arrangement in front of the catalyzer for emitting a measuring signal and a testing probe arrangement behind the catalyzer for emitting a test signal. The method includes the steps of: forming a ratio between the measuring signal and the test signal at pregiven operating conditions; evaluating said ratio as an estimating quantity for the conversion rate of the catalyzer; and, modifying output values of control parameters in a pregiven controlled manner on the basis of the instantaneous values of said ratio, said output values being applicable for controlling an internal combustion engine having a new catalyzer. This method affords the advantage that it evaluates a catalyzer with the aid of the above-mentioned ratio value and controllably modifies values of control parameters in dependence upon the evaluation ratio. This leads to an especially stable control with low toxic gas discharge.

摘要： The invention is directed to a method for controlling the no-load speed of an internal combustion engine wherein the position of the throttle flap in the intake tube of the engine is varied as a function of the speed of the engine and of a position signal defining the position of the throttle flap. The variation of the throttle flap position takes place, however, only whenever the throttle flap has assumed a specific, predeterminable position and whenever the engine speed has remained virtually constant over a likewise predeterminable period of time. An embodiment in the form of a flow chart is described by means of which the method according to the invention can be realized.

摘要： A method for the adaptation of a precontrolled value for a feedback control is based on the realization that, whenever the operating conditions coincide with the calibration conditions for the initial determining of precontrolled values, no control-manipulated variable deviations may occur in all the operating ranges, and that accordingly deviations which are nevertheless observed are a sign that the calibration conditions no longer exist. This may be caused by aging effects or by uncompensated disturbances. The method establishes the differences in control-manipulated variable deviations over different classes of an influencing variable. For each influencing variable class, a correction value is then determined such that, by means of the correction value, the error previously observed for the respective range is compensated during operation of the controlled system. The method makes possible an accurate adaptation range by range in an off-line method and is therefore suitable in particular for the precontrolling feedback control of the lambda value of an internal combustion engine. An apparatus for carrying out the method is also disclosed.

摘要： A device is proposed for burnoff of a measuring resistor, in particular a hot wire or hot film in the air flow rate meter of an internal combustion engine, wherein the occurrence of the burnoff procedures, their intensity, and their duration can be controlled in open-loop fashion. Primarily the initiation of a burnoff procedure is made dependent upon how often the driving or ignition circuit of a vehicle equipped with the engine is shut off. The initiation of the procedure can be controlled in addition in accordance with operational characteristics, for instance. The realization substantially includes a counter following the driving switch and having an associated comparator, wherein the threshold value of this comparator is controllable both in accordance with operational characteristics and, if needed, in accordance with time. Furthermore a timing element is provided with the aid of which the onset of a burnoff procedure can be delayed after the shutoff of the engine. The different intensity of a burnoff procedure can be realized via the parallel disposition of different resistors with the bridge resistors, in order to obtain a predefined bridge imbalance.

摘要： The invention is directed to a method for checking the operability of a conduit system conducting a fluid flow. The conduit system is for an internal combustion engine and utilizes two fluids having temperatures which are different from each other. In this way, it is possible to set quite well-defined measuring conditions. The fluid flow in the conduit system to be checked is coupled to the temperature sensor in such a manner that the temperature thereof changes with a relatively steep gradient when, starting at a specific time point, the above-mentioned fluid operates to warm the temperature sensor. When the magnitude of the gradient remains below a threshold value, the conduit system checked is evaluated to be operational. The measurement is reliable even though it requires only a single temperature sensor.

摘要： A method is disclosed for obtaining output values for actuating a tank venting valve connected to the intake pipe of an internal combustion engine. A control factor is supplied by a lambda controller computing step and modifies a loading factor until a regenerating fuel quantity leading to no deviation from the lambda desired value is supplied via the tank venting valve. The controlled loading factor modifies precontrol values for the regenerating fuel quantity which is supplied in an operating condition. The method takes into consideration the pressure conditions at the tank venting valve. This makes it possible to place the opening of the tank venting pipe into the intake pipe of an internal combustion engine behind the throttle flap where there is a great negative pressure, which, however, can fluctuate within wide limits. The method takes into consideration these fluctuations within a precontrolled system with superposed control which makes it possible to operate with high regenerating gas flows and, nevertheless, reliable operation. An apparatus for carrying out the method of the invention is also disclosed.
