Definition
- Noun:
- A contact in a distributor: A distributor point is a specific electrical contact point located inside the distributor of an internal combustion engine. As the distributor's rotor turns, its projecting arm makes contact with these points, allowing electrical current to flow to the spark plugs in the correct firing sequence.
Usage Examples
- Noun:
- The mechanic adjusted the distributor point to improve the engine's timing.
- A worn distributor point can cause the engine to misfire.
Advanced Usage
- Technical Context: In automotive engineering, "distributor point" specifically refers to the set of contact points within a traditional breaker-point ignition system, which is now largely superseded by electronic ignition systems.
- Older cars require regular maintenance of the distributor point and condenser.
