DISTRIBUTOR POINT Meaning and
Definition
-
A distributor point, commonly known as a points system, refers to a mechanical device incorporated in older internal combustion engines, particularly in automobiles. This device is an integral part of the ignition system and is responsible for controlling the timing of the spark that ignites the fuel-air mixture within the engine cylinders, thus enabling combustion and initiating the power stroke.
The distributor point consists of two small metal contacts, commonly made of tungsten or a similar durable material, enclosed within a distributor cap. One contact, called the fixed point, remains stationary, while the other, called the movable point, is connected to a camshaft mechanism. As the engine rotates, the camshaft mechanism causes the movable point to open and close in synchronization with the engine's firing order.
When the movable point opens, it interrupts the flow of current from the ignition coil, breaking the primary circuit. This action induces a high voltage in the coil's secondary winding, creating a spark in the spark plugs. The points then quickly close again, allowing current to flow and initiating the process for the next cylinder.
While distributor points were widely used in older vehicles, they have become less common with the advent of electronic ignition systems. These modern systems rely on sensors, microprocessors, and electronic modules to control the ignition timing, eliminating the need for mechanical points.

Etymology of DISTRIBUTOR POINT
The word "distributor point" derives from the field of automotive technology. Specifically, it refers to a component found in the ignition system of internal combustion engines. The term "distributor" refers to a device that distributes high-voltage electricity to each spark plug in the engine's cylinders. "Point" refers to the mechanical contacts within the distributor that open and close to control the spark timing. These points regulate the timing of the ignition spark, crucial for proper engine operation. The term "distributor point" emerged within the automotive industry to describe this specific component and its function within the overall ignition system.
