摘要： The proposal is for an ignition system for internal combustion engines with a monitoring circuit (9) which, on the occurrence of defective ignition, takes suitable emergency measures to protect the catalyst. To this end the ignition system comprises an evaluation device (10) which applies a statistical weighting to the ignition diagnosis signal (ZÜND OK) and, when a certain threshold of the weighted ignition diagnosis value (ZÜNTAB) is exceeded, triggers suitable emergency measures, whereby the evaluation is continued so that, when the figures drop below the defect threshold (AFSDZU), correction is recognised and the emergency measures are lifted.

摘要： The invention concerns a method of controlling ignition in a multicylinder internal combustion engine, the control variables being determined with reference to the parameters detected by sensors and misfiring being monitored as a function of the output of the control variables. When an ignition signal is emitted, the torque at the combustion step triggered by the ignition is detected and compared with a mean value of the torques of preceding combustion steps. If, in this respect, a deviation in the torque detected at a given moment from the mean value of the torques of preceding combustion steps is greater than a predetermined threshold, the misfiring detection system is switched off.

摘要： A sensor wheel (10) is used, for example, to detect variations in the speed of an internal combustion engine with a high degree of accuracy so that an erratic running value can be calculated from these variations. Such a sensor wheel comprises three segments, for example, which ideally are of equal length but in reality are usually of slightly different lengths. In order to avoid measuring errors owing to these differing lengths when detecting variations in the speed, the actual lengths can be determined by a known adaptation process. The device of the invention is constructed such that it has a plurality of adaptation filters (17.B1 to 17.B4) for each segment in order to detect different adaptation values for different speed ranges since it has emerged that different lengths are measured in different speed ranges, which is an error which has to be compensated for, since the length of a segment is actually permanently constant.

摘要： The torque of an internal combustion engine is controlled during acceleration by monitoring differences between engine and wheel speed in order to provide a measure of phase differences in the event of the engine torque oscillating. The difference between the engine and wheel signals is integrated and fed to an ignition angle correction circuit in order to damp out the torque oscillations which would otherwise result.

摘要： The resetting circuit is intended to be used with a microprocessor. The microprocessor is reset if it deviates from a set program. At each cyclic input signal, a control is carried out to know if, after a certain time interval, an output signal appears. If it is not the case, a resetting is effected. Furthermore, the resetting is effected when a given output of the microprocessor remains too long in a certain position.

摘要： A process for testing the controllability of a tank ventilation valve (TVV) and an idling control is proposed. After the TVV has been actuated, an additional air/fuel mixture is taken to the inlet region of an internal combustion engine, the air/fuel ratio of which may be the same as that with which the engine usually operates ( lambda 0) or higher or lower than this value. Dependently thereon it is possible to assess reactions of a lambda and/or an idling adjustment. It is an advantage that a check can be made regardless of the degree to which the additional air/fuel mixture is enriched with fuel.

摘要： A disadvantage for controlling idling in internal combustion engines is that when the adjusting motor is excited and the spring fails to operate, the device is fully opened and in consequence the internal combustion engine contains a dangerous amount of fuel. The device is designed so that in the exit position it opens an emergency cross-section which corresponds to point (A) on the curve and through which an emergency quantity of fuel can flow per unit time. When an adjusting motor of the device is excited, a throttle organ is first moved against the force of a spring into a position (s1) corresponding to point (B) on the curve in which the maximum possible quantity of fuel can flow through a control opening in unit time. Thereafter, the quantity of fuel per unit time is adjusted by means of the throttle organ as far as position (s2), in which position the throttle organ closes the control opening. Should the spring break while the adjusting motor is excited, the throttle organ is further adjusted into position (s4) corresponding to point (E) on the curve in which a safety cross-section is opened through which can flow a quantity of fuel per unit time less than that which flows through the fully opened control opening. The device is used to adjust idling in internal combustion engines.
