by a gasoline engine ignition system periodically cylinder firing order to spread the high voltage spark plug of each cylinder member.
In battery ignition systems, the distributor and typically do breaker on the same axis, by a valve driven by the camshaft. It also has adjusting means and the ignition timing capacitor. Off breaker contact arm spring piece using closed off cam with the contacts open, opening a gap of about 0.30 to 0.45 mm. The number of cam projections off the same number of cylinders.
When the contact is open, the distributor arm distributor exactly aligned with the corresponding side electrodes, a high voltage induced by the secondary coil through the distributor arm, electrode side, high-voltage wiring spread corresponding cylinder spark plug. When different octane gasoline can be adjusted manually First set ignition advance angle.
When the engine speed increases, the centrifugal ignition timing of the ignition advance angle adjusting means, and vice versa after the ignition delay. When the engine load decreases, the degree of vacuum in the intake manifold to increase, through a connecting pipe to a vacuum being ignition advance angle adjusting means, the ignition advance. Such adjustment ensures the engine operation at the appropriate ignition timing. In the magneto ignition system, like breakers typically done in the magneto form a whole.
