摘要： In a method for the malfunction testing of an idling control arrangement for an internal combustion engine, the closing function of the idling contact is checked. As soon as it is established that the contact should really be closed but that this is not the case, it is certain that there is either an interruption in the idling contact circuit or a servomotor fault. In order to be able to distinguish which of these faults is present, a test movement sequence is carried out in which the servomotor of the arrangement is activated and a check is made whether the throttle flap angle changes. If this is not the case, the servomotor is defective; otherwise, an interruption in the idling contact circuit is present. Using this method, it is for the first time possible to detect interruption and servomotor faults. Until now, it was only possible to detect short-circuit faults. Such short-circuit faults can also be detected using a method according to the invention, and in particular with greater reliability than so far, since a smaller angle is used in the test condition than unit now.

摘要： The invention is directed to a system for setting the throttle flap angle for an internal combustion engine. The system sets the idle stop for the idle throttle flap angle and monitors the setting with respect to defects that occur. If the throttle flap is in contact engagement with the idle stop, a contact is actuated which causes a buffer storage of the actual throttle flap angle which thereby represents the position of the idle stop. If then, for example, the idle stop changes during driving operation, its new position is established upon a renewed contact engagement of the throttle flap, by measuring the throttle flap angle. A possible defect can be established from a comparison of actual and desired values and a positioning motor is then appropriately driven to displace the idle stop. This system has the advantage that a defect occurring in the region of the positioning motor is detected without additional circuit complexity.

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 starting control for fuel injection systems of internal combustion engines is suggested in which an injection time (te.sub.VER), which is dependent on the engine starting temperature (T.sub.MS), is determined in the starting phase. In the starting phase, this injection time (te.sub.VER) follows the curve of special starting characteristic lines. A continuous transition to performance characteristics injection time (te.sub.KF) is effected by means of a comparator. A smooth transition from the starting phase to normal operation is obtained in this way.

摘要： In a fuel injection system with an acceleration enrichment and a deceleration leaning, in which the transition compensation is determined by means of the throttle valve change speed in connection with the throttle valve change path. By means of the measurement of the throttle valve position the cause for the change of the air quantity is determined so that the information concerning a change of the operating state is present more quickly and a fuel leaning or fuel enrichment can accordingly also be effected more quickly. An intermediate injection threshold, which activates an intermediate injection calculation when exceeded, is built in, in addition, for the acceleration enrichment.

摘要： In a method and apparatus for controlling tank venting in internal combustion engines, a regenerative flow of fuel is released from the activated charcoal container to the negative-pressure side of the intake tube of the engine and an adaptation in the computer area for the fuel metering quantity simultaneously is prohibited, or vice versa, an adaptation is authorized and a regenerative fuel flow is prohibited, by cyclical triggering, as a function of whether the throttle flap angle drops below, or exceeds, a predetermined threshold value. Parallel to this, a continuous activated charcoal filter regeneration is provided that comes into play at relatively large air throughputs, by means of a branch line leading into the air filter area upstream of the throttle flap; furthermore, if the throttle flap angle threshold value is exceeded, both the regenerative fuel flow via the tank venting valve and the adaptation in the computer area are authorized.

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： 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.

The fuel supply line has an elastic wall section, with which is connected a rigid wall section and on which are fastened the supports. The elastic wall section is elastic to the extent that it damps the pressure pulsations of the fuel in the fuel supply line, whereas the rigid wall section assures the required rigidity of the fuel supply line.
