A distributor rotor is the component in spark ignition systems that routes spark from an ignition coil to the proper contact inside of a distributor cap. This facilitated the rotation of a distributor shaft, which typically moves in sync with a camshaft. Although they share similar names, distributor rotor should not be confused with brake rotors.
Every rotor has three basic design components:
a solid body (typically injection-molded plastic)
a metal contact
some means of attaching to the distributor shaft
Distributor rotors work by providing a movable connection between an ignition coil and a set of spark plugs. When the engine is operating normally, the distributor shaft rotates in time with the camshaft. In turn, Then it turns in time with the distributor shaft.
When a distributor rotor fails, the engine will typically run poorly or fail to run at all, most failures are due to wear or buildup on the electrical contacts, both of which prevent adequate (or any) spark at the spark plugs.
replace the rotor from time to time for normal wear and tear, Since the distributor are wear items.
In some cases, a rotor can fail in other ways. If it spins on the distributor shaft, the ignition timing will no longer be correct, in the same way that rotating the main body of a distributor will change the ignition timing. That can cause anything from a no-start condition, to a poorly running engine, or even severe backfiring, depending on exactly how off the orientation is. This may be caused by a bad insert, stressed housing, or a fastener that has backed off.
