Sisäänajolla

Sisäänajolla is a Finnish term that broadly translates to "running in" or "break-in period" in English. It refers to a crucial phase for new mechanical components, particularly in vehicles, engines, and machinery, before they are subjected to full operating conditions. The primary purpose of sisäänajolla is to allow moving parts to gradually seat and wear against each other, reducing friction and improving longevity.

During the sisäänajolla period, components are operated at reduced loads and speeds. This gentle introduction helps to eliminate microscopic imperfections and irregularities present from the manufacturing process. It allows mating surfaces to conform to each other, creating a more uniform and efficient contact area. For engines, this can involve avoiding high RPMs, heavy acceleration, and prolonged idling, while for other machinery, it might mean operating at lower pressures or speeds.

Failing to properly conduct the sisäänajolla phase can lead to premature wear, increased friction, overheating, and ultimately, a shortened lifespan for the component or machine. A successful sisäänajolla results in a more reliable, efficient, and durable product. The duration and specific procedures for sisäänajolla vary greatly depending on the type of equipment and manufacturer recommendations, often detailed in user manuals.
