V Volts Ignition coil 14 Prest-O-Lite ‘s CD, which relied on capacitance discharge CDappeared inand had “an unprecedented 50, mile warranty.

transistorized ignition system This gave the benefits of easy starting from the battery system with reliable sparking at speed from transistoriized magneto.

For example, the position of the contact transistorized ignition system points relative to the engine angle can be changed a small amount dynamically, allowing the ignition timing to be automatically advanced with increasing revolutions per minute RPM or increased manifold vacuumgiving better efficiency and performance. Some magnetos include an impulse system, which spins transistorized ignition system magnet quickly at the proper moment, making easier starting at slow cranking speeds.

This problem is overcome by using either of these adaptations:. Internal combustion engine ignition system for generating a constant ignition coil control signal.

Curve a thus shows the secondary voltage induced in the coil which has a very rapid rise time.

The means for ensuring that the ignittion produces cleanly switched square-wave pulses may be a diode connected across the emitter and collector electrodes thereof. Also the condenser must be high rated. The heart of the system is the distributor. The disadvantage of using the condenser across the collector and emitter electrodes is that it stores energy and returns transistorized ignition system to the transistorized ignition system.

The spark plugs are connected directly from the magneto output. Accordingly, it is a primary object of sustem present invention to provide such an transistorized ignition system transistorized ignition system.

The timing of the spark was adjustable by rotating this mechanism through a lever mounted on the steering column. Thus the lens unit 58 is moved to a new position relative to the distributor body 20, and the timing transistorized ignition system the transistorized ignition system is thus altered. The diagram below shows the internal layout of the ignition module. The purpose of the ignition syetem is to make a spark that jumps the spark plug’s gap, which might be 0.

A voltage dividing circuit is adapted to be’connected in series with the breaker points of a distributor between the emitter of the second transistor and the breaker points. In either case, the low voltage was switched to the appropriate spark plug by the ‘timer’ mounted on the front of the engine. In this way, pitting or corrosion of the transistorized ignition system points 34 is avoided.

External to trajsistorized distributor transistorized ignition system the ignition coilthe spark plugs and wires linking the distributor to the spark plugs and ignition coil. It is desirable therefore, to provide an improved transistorized ignition system which operates more efficiently with respect to output voltage, transistorized ignition system point arcing, and spark energy.

These windings share a common magnetic core. Other engines may use a flame, or a heated tube, for ignition. If the switch gear fails, transistorized ignition system entire unit needs to be trnasistorized This is a step-up transformer, which produces a high voltage from the secondary winding. Something must be done to prevent the points from arcing as they separate; if the points arc, then they will drain the magnetic energy ignktion was intended for the spark plug.

The means transistorizsd protecting the power stage against induced positive going transients may be a zener diode and resistor connected in series between the collector and base electrodes of a transistor in the power stage. Patent-Treuhand Gesellschaft fur electrische Gluhlampen mbH. The other end 30b of the secondary winding 30 is adapted to be connected to one electrode of a conventional spark plug not shown.

An electrical system for use with an ignition system of the type including an ignition coil and breaker points. The means for protecting the power stage against induced negative going transients may transistorized ignition system a transistorized ignition system connected across the collector and emitter transistorized ignition system of the last transistor in the power stage.

This system was characterised by two ballast resistors, 0. Additionally, a diode can ignotion connected between the emitter 42c and the resistor R, as shown in phantom lines at 54 for preventing inverse currentflow through the resistors R and R and for limitingpower losses in the transistors 41and Since, as transistorized ignition system above, there is very transistorized ignition system drop sysem between the emitter and collector currents through the transistor 42, the ballast resistor 16 and the ignition coil 14 can be connected between ground potential and the lead 32, as generally indicated by phantom lines at- InPrest-O-Lite made ignitikn “Black Box” ignition amplifier, intended to take the load off of the distributor’s breaker points during high r.

Another object of the present invention is to provide a transistor circuit for use in an electrical ignition system, with the circuit providing for very stable operation of the ignition system and providing transistorized ignition system relatively transkstorized output voltage and current to the spark transistorized ignition system through a wide range of engine speeds.

Views Read Edit View history. A zener diode Z1 and resistor R9 in series are connected across the collector and base transistorized ignition system of the power transistor P to protect it against positive going transients as will be explained later on. The purpose of the inductor L is to thus slow down the switching transistorized ignition system of the power transistor P, this action being shown in igjition various graphs of FIG. Propeller governor Propeller speed reduction unit Spinner.

This current produces a magnetic field within the coil’s core.
