Abstract: A distributor containing an apparatus for suppressing noise is described, comprising a first discharging gap which exists between electrodes of a distributor rotor and a stationary terminal, both of which are located in the distributor and a second discharging gap to which a resistance element is connected in series, wherein the second discharging gap and the resistance element are connected close to and also, electrically parallel to the first discharging gap.

Abstract: An ignition system for internal combustion engines which comprises a magneto electric generator having a generating coil for producing two output signals different in phase, a capacitor which will be charged and discharged to operate a high tension coil, a switching element for discharging the capacitor, and a control circuit for controlling the switching element, one of the two output signals charging the capacitor, the other output signal controlling the switching element through the control circuit with the results that the control voltage of the switching element is not affected by the ambient temperature and the ignition system is made smaller in size, is serviceable for preventing excessive rate of rotation of the combustion engine, and can be molded into one unit.

Abstract: A two cylinder, two cycle engine for an outboard motor includes an alternator driven, capacitor discharge ignition system. The alternator includes an annular permanent magnet secured within a flywheel skirt and includes a pair of circumferential opposite poles with diametrical spaced neutral areas. The magnet is a flexible ferrite strip with a butt joint at one of the neutral areas. A stator assembly is mounted within the annular rotor and includes a semicircular core with a charging coil at each end. Each movement of the magnetic gap means past the coils generates a pulse. A trigger coil within a housing is mounted in coplanar relation between the charging coils, with a pole aligned with and spaced from the stator core. The housing is rotatably mounted and includes an integral cam for positioning a throttle lever.

Abstract: A system for the digital-electronic control of the inlet-, exhaust and possibly injection valves as well as of the ignition of internal combustion engines, especially of motor vehicle internal combustion engines, in which the valves are electromagnetically actuated and the respective crankshaft position is adapted to be detected digitally; a fixed value memory or storage device is provided in which at least for one cylinder the opening and closing instants of the inlet, exhaust, and possibly of the injection valves and/or of the ignition instants are at least partly adapted to be stored and selected as digital values coordinated to the respective operating conditions and corresponding to a predetermined crankshaft position in the form of data sets; a storage register is provided for each stored value of a data set to which this stored value is adapted to be transferred; a pulse comparison unit is also provided for each value of a data set in which the value either stored in the storage register or fixedly pre

Abstract: Capacitor discharge ignition system for a spark-ignition internal combustion engine. The ignition system employs an ignition coil having primary and secondary windings wound on a ferromagnetic core, preferably made of a ferrite material. A first capacitor is connected in series with a spark gap and this series combination is connected across the ignition coil secondary winding. The ignition coil primary winding has a second capacitor coupled to it which capacitor is charged and then discharged in timed relation to engine operation. The first capacitor and ignition coil windings and construction are selected such that the second capacitor when discharged through the ignition coil primary winding produces ferroresonant oscillations in the secondary circuit of the ignition coil. This breaks down the spark gap and an alternating voltage, at the ferroresonant frequency, occurs.

Abstract: The injection timing of a fuel injection pump is controlled by displacement of a helical splined sleeve interconnecting a driving shaft and an injection pump drive shaft to vary the angle between the shafts. According to this invention the displacement of the sleeve is effected by an hydraulic actuator controlled by an electronic circuit which is responsive to a number of engine operating parameters and which receives a feedback signal from a detector, preferably magnetic, of the actual relative angular displacement between the shafts to ensure that the actual angle between the shafts is that required by the operating parameters.
