摘要： The invention relates to a method and an arrangement for checking the operability of an electric heater in motor vehicles and especially the heater of an oxygen probe which is mounted in the exhaust gas channel of an internal combustion engine. It is necessary to determine the temperature-dependent electrical resistance and the temperature of the oxygen probe heater for a precise evaluation of the operational state of the oxygen probe heater. The basic principle of the invention is based upon the consideration that the measurement of the electrical resistance of the oxygen probe heater is then carried out when the oxygen probe heater has cooled down to the ambient temperature. Whether this cool down has taken place can be determined in various ways in accordance with the invention, for example, from the cool down of the engine block or by a comparison of the engine block temperature to the intake-air temperature. The operating state of the oxygen probe heater so determined is displayed to the driver by the activation of a corresponding control device and/or, if required, read into a fault memory.

摘要： A transmitter wheel is used for example to detect speed changes of an internal combustion engine with high precision in order to calculate a running imbalance value from them. A transmitter wheel of this kind has for example three segments, which are ideally the same length, but in reality usually have lengths which differ slightly from one another. In order to prevent measurement errors which are caused by this, it is known to determine the actual lengths by means of an adaption process. The device according to the invention is embodied such that for each segment, it has a plurality of adaption filters to detect different adaption values for different speed ranges. It has namely turned out that in different speed ranges, different lengths are measured, which is an error that must be compensated for since the length of a segment is in fact actually constant.

摘要： The invention is directed to a method of checking the tightness of exhaust valves of an internal combustion engine with the aid of an apparatus. The apparatus includes a device for forming a value LU for the uneven running of the engine and a device for metering air into a region disposed downstream of the exhaust valves as viewed in the flow direction of the exhaust gas. In the method, a first value LU1 is formed for the uneven running without air being supplied in the above-mentioned region and a second value LU2 is formed for uneven running with air being supplied in the above-mentioned region. An exhaust valve is deemed to leak when the first and the second values for the uneven running differ by more than a predetermined amount.

摘要： A temperature-dependent base desired value for the opening angle is determined in a method for precontrolling the opening angle of a throttle flap during the idle engine-speed control of an internal combustion engine. This temperature-dependent base desired value is then modified within a start-time duration. The modification takes place in that, during start, a temperature-dependent angle increase is determined which is multiplied by a time-reduced multiplier factor and the product is additively superposed on the base desired value. With this procedure, and notwithstanding the simple method sequence, it is ensured that the start phase of a warm internal combustion engine takes place without engine-speed increases. It is especially advantageous to modify additional engine-speed base desired values in a corresponding manner. In this case, hardly any additional measures must be undertaken which go beyond those which must be undertaken to modify the base desired value for the opening angle of the throttle flap. For cold starts, an increase of the engine speed is obtained in the start phase without the danger being present that the increase takes place for warm engines.

摘要： A method for monitoring a system for delivering secondary air to an exhaust tube of an internal combustion engine. In the method a secondary air pump is switched on and builds up a pressure on the inlet side of a blocking valve which is normally closed and not being acted upon. The blocking valve has a valve closing member that is acted upon by a predetermined closing force of an elastic element. If the secondary air quantity pumped by the secondary air pump reaches a certain minimum air quantity and pressure, then with the then-opened blocking valve, a lambda sensor disposed in an exhaust tube detects a change in the lambda value in the exhaust tube that exceeds a predetermined threshold value. The method is suitable for monitoring the function of a system for delivering secondary air to the exhaust tube of an internal combustion engine.

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 an arrangement for adjusting an operating characteristic quantity of an internal combustion engine such as for the idle speed control with a redundant drive. Two windings of the drive are driven via two separate lines from two separate output stages. When a defect is detected via an electrical monitoring unit, a safety logic unit transfers the full operation for the drive of the throttle flap to the output stage and the winding corresponding thereto which are not affected by the defect. In this way, a noraml idle speed of the engine is assured even in the presence of a single defect.
