Special seal types and their features
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.
In the automotive industry, spark plugs are essential for the proper functioning of internal combustion engines. Whether in gasoline or diesel engines, spark plugs play a crucial role in igniting the air-fuel mixture, initiating the combustion process that powers the vehicle. High-performance spark plugs designed for specific automotive applications can enhance engine performance, fuel efficiency, and emissions control, contributing to the overall reliability and longevity of the vehicle.
