    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: Apparatus and method for a plasma discharge for ignition in an internal combustion engine (10). A digital electronic system controls ignition performance and can provide an ignition discharge throughout an entire power stroke of a piston in a cylinder. The discharge can be controlled by a signal from a conventional distributor, crank trigger or other source (13). Controllable discharge of a capacitor (C2) occurs through the primary winding of an ignition coil (46). In addition, the capacitor (C2) may be both discharged and recharged in as oscillatory manner through the primary of the ignition coil (46). Such oscillatory discharging and recharging of the capacitor (C2) results in energy being delivered to the spark plug (50) during both discharge and recharge cycles, thereby resulting in the delivery of discharge energy to the spark plug (50) on a substantially continuous basis.

    摘要: A pulse shaper for inductive transmitters, in particular camshaft angle transmitters on internal combustion machines, in wich a Schmitt-trigger is connected to the output of the transmitter. A peak value detector (D1, C) is connected to the output of the transmitter and means (R3, R4) are linked therewith in order to set a threshold value for the Schmitt trigger depending on the output of the peak value detector.

    摘要: An auxiliary revolution sensor (l6) is disposed for detecting a reference position signal (l6a) of each cylinders. A computer (3) outputs an auxiliary reference cylinder signal (3d) by the reference position signal (l6a). A pseudo reference position signal generator (l2, l3, l4, l5) generates a pseudo reference position signal (l5a) by the auxiliary reference cylinder signal (3d). An electronic distributor (5) outputs ignition signals (6) to ignitors (6-ll) by outputting signals of the pseudo reference position signal generator and the computer, when a revolution sensor (l) is out of order.
