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： 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： 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 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： 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： To prevent change of data in a non-volatile programmable, ready-only memory (25) forming, together with a microprocessor (23) a control unit, for example for an automotive vehicle, while permitting programming of the memory from an external programming unit (P, 1), an interface (3, 11, 12) is provided through which a release-enable bus (13) also passes, data being transmitted in accordance with a predetermined characteristic--even or odd parity--, the parity correctness being checked. If the parity is correct, an "enter" signal is provided on the release-enable bus for storing the data; if not, retransmission is attempted for a predetermined number of time, and if it cannot be correctly effected, a malfunction indication output signal is generated.
