General Technical Info

Functioning of the internal rotor ignition from PVL

In this ignition system is a CDI ignition (Capacitive Discharge Ignition).

The ignition works independently of the other power supply (battery) and generates electricity itself for the ignition rotor and the stator.
A CDI ignition is completely maintenance-free. An electronic system controls the discharge of the ignition. Adjusting and changing a mechanical breaker is eliminated. The ignition must only be adjusted once during the installation and setup. No maintenance or adjustment of the system is necessary.

The ignition system consists of the following 3 components:

  • coil
  • stator
  • rotor

Operation of a loading and unloading

Rotor and stator are each equipped with two powerful magnets.
By the rotation of the crankshaft, and thus of the rotor by the magnets electric voltage is generated. With a charging coil in the stator, a capacitor in the ignition coil is loaded. The command of the electronics, the voltage is discharged through the spark plug.
The system can be used universally on each motor.

Technical data of the ignition primary voltage: 270 V
Operating voltage: 700 – 800 V
Spark duration: 260 us
Maximum speed: 27,000 rev / min (electrical and mechanical)

PVL Ignition coil

The most important component of an ignition system is the ignition coil. The integrated electronics directs and controls the timing of the discharge of the stored ignition curve.
The curve is crucial for performance, maximum speed and engine response. The ignition curve is therefore essential to the characteristics of the engine match. Engine damage or loss of output are usually the result.
The stator and rotor lists and diagramms are necessary data. Always consider the following when selecting the technical requirements (dimensions) and the characteristics of your engine.
There is sometimes a choice of connectors (see SG1526). The plugs have no effect on the ignition. It just disconnect the plug from the stator coil and match.
