The Czech word "výkonovými" is the instrumental plural form of the adjective "výkonový". This adjective generally translates to "performance-related" or "power-related" in English. It is used to describe things associated with performance, output, capacity, or power.

For example, "výkonovými parametry" would refer to performance parameters or specifications. If one were discussing "výkonovými testy," it would mean performance tests or power tests. In the context of engineering or technology, "výkonovými komponenty" would indicate performance components or power components. The instrumental case suggests that these "performance-related" or "power-related" items are being used as a means or by means of something. Therefore, a sentence using "výkonovými" would likely describe an action or state achieved through or involving these performance or power aspects.
