Sisäänajoon

Sisäänajoon, often translated as "break-in" or "running-in" period, refers to a phase in the life of a new mechanical component or system where it undergoes initial use to allow its parts to wear in and settle. This process is particularly relevant for engines, transmissions, and other complex moving parts in vehicles, but can also apply to new appliances or machinery.

The primary purpose of sisäänajoon is to achieve optimal performance and longevity for the component. During this period, friction between moving surfaces is higher than usual, and the parts gradually conform to each other. This can involve careful operation, avoiding extreme conditions like high speeds, heavy loads, or rapid acceleration. For engines, it might mean varying engine speeds and avoiding prolonged idling.

Following the manufacturer's recommended break-in procedure is crucial. Deviating from these guidelines can potentially lead to premature wear, reduced efficiency, and a shorter lifespan for the component. Once the specified break-in period is complete, the component is considered fully settled and ready for normal operation. The exact duration and procedures for sisäänajoon vary significantly depending on the specific item and its intended use.
