What is the structure of the engine distributor?

1

What is?

by a gasoline engine ignition system periodically cylinder firing order to spread the high voltage spark plug of each cylinder member.

Function

distributor is used to turn on and off the low voltage circuit, high-voltage current of the ignition coil, and in accordance with the firing order of the engine, within a predetermined period of time, will be assigned to a high-voltage spark walled each cylinder, ignite the mixture. Distributor ignition system is mainly used in traditional and common electronic ignition system, both of the ignition system has basically been eliminated. Now the car engine basically canceled the distributor said Distributorless computer control ignition system.

Composition

by a breaker, distributor , capacitors and ignition timing adjustment mechanism.

works

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 contacts open, the distributor arm is precisely aligned with a respective distributor-side electrode, a high voltage induced by the secondary coil through the distributor arm-side electrode, the high pressure transmitted to the respective cylinder spark plug lead.
