摘要： A device for identifying the position of a shaft of an internal combustion engine has a generator disk linked with the shaft and having at least one reference mark. The generator disk is scanned by a sensor and the thus obtained output signals are evaluated in a control apparatus. For the position of the shaft to be known as soon as the internal combustion engine is started, the last detected position of the shaft after the internal combustion engine is turned off and the shaft has stopped is stored in a non-volatile storage of the control apparatus and is used when the internal combustion engine is restarted to determine and control the first injections during a starting phase. In order to improve accuracy, sense of rotation identification is also provided, so that a correction may be carried out should the shaft turn slightly backwards when the engine swings back.

摘要： The description relates to a sensor arrangement for cylinder identification in a multi-cylinder internal combustion engine with a crankshaft detector with an increment disc with a reference marking and a camshaft sensor with long and short segments and short and long spaces between the segments. The joint evaluation of the pulse sequences provided by both sensors allows to determine the length of the high and low phases. As the reference mark is also taken into account in the evaluation, the number of different segment lengths on the camshaft sensor disc can be reduced and the cylinder identified rapidly and positively. The evaluation of the crankshaft and camshaft signal provides for reliable control of the internal combustion engine. If the crankshaft sensor breaks down, the engine can still be run in emergency with the aid of the camshaft sensor.

摘要： In the fuel injection control device described, immediately after the engine has been started up, the position of the crankshaft and camshaft is determined. This is achieved either by means of an absolute transmitter system or by identification of the stopping point, with the angular position of the crankshaft or camshaft being memorized when stationary. Immediately after the engine has been restarted, fuel is injected into an open inlet valve in the appropriate phase. On commencement of rotation, further injections are triggered into one or several open or still closed inlet valves. Once correct synchronization has been achieved, the control device switches over to normal injection.

摘要： A method is disclosed of reducing exhaust emissions when combustion engines are switched off. The purpose of the method is to reduce the emission of unburned fuel mixture once the engine has been switched off and in particular when the engine is started up again later. To this end, when the engine is switched off, i.e. the ignition lock opened, the fuel injection is switched off and the ignition cut-off delayed to allow the cylinders to fire at least one more time.

摘要： The invention pertains to a device for determining the rotational speed gradient dn/dt of a shaft of an internal combustion engine, where the rotational speed gradient dn/dt is determined in the control unit as a function of the cube of the engine speed and the difference of two segment times, the speed gradient being determined only in time-uncritical phases, whereas in the time-critical phases only segment times are read or stored so that in these time-critical phases the data required for the control of the internal combustion engine can be computed independently of the engine speed determination.

摘要： Proposed is a device for monitoring the operation of an electric/electronic switch controlled by a control circuit, its in-circuit consumers, its control and its connectors. The device is characterized by the fact that at least one logic circuit (5) is connected in parallel with the output stage (3) so that the input-terminal potential (UE), the output-stage (3) output-terminal potential (UA) and a reference potential (Uref) can be applied to the logic circuit. The circuit can differentiate with certainty between the fault conditions overload/short to plus, drop in load and short to earth, and diagnose correct operation of the output stage. Faults (implausible events) in the output stage, the consumer (R), the control unit or its connectors are stored by means of an encoder (7) in an intermediate store (9) which can be read out on interrogation by the control circuit (νC) into a store (11) from where they are passed to an interface (P4) with the control circuit. In this way, faults can be attributed to a particular output stage and easily identified. A cut-out switch protects the output stage from overload. The cut-out switch can also switch out output stages at defined points in time, e.g. during the initialization phase.

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： An ignition circuit for an internal combustion engine comprises a customary primary circuit. The secondary circuit is modified by connecting the end (21) of the secondary winding (L2) not connected to the central electrode of a spark plug (24) to vehicle earth so as to cause the discharge current of the capacitance of the secondary winding (L2) to flow directly to earth whereby substantially reducing radio frequency interference and inhibiting interference in the cable harness due to ignition interference.

摘要： A method and device are proposed for detecting and documenting damage to catalytic converters caused by critical fuel levels in the fuel tank (10) of an internal combustion engine vehicle (12), the critical fuel levels in question being detected by a level meter (9). The level measurements obtained by the level meter are identified by a circuit (4), indicated by a fault indicator light (1) and recorded in a memory (8) together with the operational status of the fault indicator light as stored data; engine backfires are identified and recorded in the memory as supplementary stored data; and, where backfires and critical fuel levels as indicated by the fault indicator light are found to be present simultaneously, the stored data are linked in the memory so that it is possible when the linked stored data are read out later to ascertain whether or not the backfires were caused by a critical fuel level.

摘要： The invention is based on a system for altering a signal representing a rotary movement in a motor vehicle with first means (5030, 5031, 5032) for generating a first signal representing the rotary movement and second means for generating at least one second signal representing further data (direction of rotation, air gap and/or brake lining wear). In addition there are third means (5021, 5022, 5024) by means of which the first signal (revolution speed signal) can be altered depending on the second signal (direction of rotation, air gap and/or brake lining wear). The essence of the invention is that the first means are designed in such a way that the first signal (revolution speed signal) assumes at least two first currents and/or voltages. In addition, according to the invention, the third means are designed in such a way that, in order to alter the first signal (revolution speed signal), at least one of the first currents and/or voltages can be changed into at least one second current and/or voltage for at least a given time depending on the second signal (direction of rotation, air gap and/or brake lining wear).
