Tändspänning

Tändspänning, also known as spark plug gap, refers to the distance between the center electrode and the ground electrode in a spark plug. This gap is crucial for the proper functioning of an internal combustion engine, as it determines the voltage required to create a spark that ignites the air-fuel mixture in the combustion chamber. The ideal tändspänning varies depending on the engine type and manufacturer specifications, typically ranging from 0.025 to 0.040 inches (0.64 to 1.02 mm).

The tändspänning is set during the manufacturing process and is often marked on the spark plug body. It is essential to maintain the correct gap to ensure optimal engine performance, fuel efficiency, and emissions control. If the gap is too large, the spark plug may not generate enough voltage to ignite the fuel, leading to misfires and reduced engine power. Conversely, if the gap is too small, excessive voltage can cause pre-ignition, which can damage the engine and reduce its lifespan.

Regular inspection and maintenance of the spark plug gap are recommended to ensure the engine operates at its best. If the gap is found to be worn or damaged, the spark plug should be replaced to maintain proper engine function. Additionally, using the correct tändspänning for the specific engine and operating conditions is crucial for achieving the best performance and longevity of the engine.
