SPARK LEVER Meaning and
Definition
-
A spark lever, also known as a spark advance lever, is a mechanical device used in internal combustion engines to adjust the ignition timing of the engine. Specifically, it is a lever that controls the position of the distributor and determines when the spark plugs ignite the fuel-air mixture in the engine's cylinders.
The spark lever is typically located on the steering column or dashboard of a vehicle, within reach of the driver. By moving the lever forward or backward, the ignition timing can be advanced or retarded, respectively. This adjustment is necessary because the ideal timing varies depending on various factors, such as engine speed, load, and operating conditions.
Advancing the spark lever means setting the ignition timing to occur earlier, resulting in the spark plugs firing the mixture earlier in the piston's upward stroke. This is typically done during acceleration or when the engine requires more power. Conversely, retarding the spark timing means delaying the spark plugs' firing to occur later in the piston's stroke. This is often applied during deceleration or when the engine operates at lower speeds.
The spark lever gives the driver control over the ignition timing, allowing them to optimize engine performance and fuel efficiency. It is especially important in older vehicles without electronic ignition systems, where manual adjustments are required.

Etymology of SPARK LEVER
The word "spark lever" is a compound term, composed of two individual words: "spark" and "lever".
1. Spark: The word "spark" is derived from the Old English word "spearca", which originally referred to a small particle or shining fragment that was emitted by fire or a burning material. Over time, the meaning of "spark" extended to indicate a small fiery particle that is visible in combustion.
2. Lever: The word "lever" comes from the Old French word "levier", which derives from the Latin word "levare", meaning "to lift" or "to raise". It refers to a simple machine consisting of a rigid bar that is used to transmit a force or motion around a fixed point called a fulcrum.
When combined, "spark lever" refers to a device used to ignite the spark plug in older internal combustion engines.
