摘要： In an ignition coil for an internal combustion engine, a resistor is disposed in a tower insertion hole of a high-voltage tower section. A coil spring is inserted in the tower insertion hole. An inner diameter of a proximal end side portion of the tower insertion hole is larger than an outer diameter of a maximum outer diameter portion of the resistor. An inner diameter of the distal end side portion of the tower insertion hole is larger than an outer diameter of a proximal end side portion of the coil spring, and is smaller than the outer diameter of the maximum outer diameter portion. In a state where the coil spring is pulled out from the tower insertion hole, the maximum outer diameter portion is restrained by the distal end side portion of the tower insertion hole, and a gap is formed between the resistor and a high-voltage cap.

摘要： To provide for gradual turn-off of an ignition coil current control transistor, a control capacitor which provides turn-off current has its charge state changed gradually by means of an auxiliary transistor so connected to the capacitor that the conduction of the emitter-collector path of the auxiliary transistor is gradually changed, the main switching transistor being connected to and controlled by the auxiliary transistor and likewise changing gradually from conductive to blocking state in dependence on the gradual change in conduction of the emitter-collector path of the auxiliary transistor to prevent rapid turn-off of the main switching transistor and hence an undesired pulse at the secondary of the ignition coil which may induce continued operation of the internal combustion engine even though the ignition has been turned off.

摘要： A control device is proposed for an electromagnetic engine valve or an electromagnetic final control element. The control device operates with closed-loop current control, and the maximum current is ascertained via a measuring resistor located in series with a switching transistor, while the free-running circuit is controlled in accordance with time. This control in accordance with time is effected via a comparator having dynamic positive feedback and acting as a comparison stage. The free-running control circuit includes a diode for protective purposes switched parallel to a transistor.

摘要： In a spark ignition system it is possible for a vehicle to stall with the contact breaker closed, and for a transistor or other device in series with the ignition coil to conduct heavily. This problem is overcome by limiting the time for which the ignition coil can be energised.

摘要： A d-c energized ignition system for internal combustion engines is first provided with negative feedback means for stabilizing the energizing current flowing through the primary winding of the ignition coil, and is secondly provided with means for automatically interrupting the current flow through the primary winding of the ignition coil in case that the operation of the internal combustion engine is interrupted at a point of time when the cooperating contacts of the interrupter are in engagement.
