In what episode is ash moferno involve into inferno?

It seems you're asking about Ash Ketchum's involvement with Inferno, but there isn't an episode in the Pokémon anime where Ash is directly involved in a situation specifically named "Inferno."

It's possible you're thinking of a different episode or have a different interpretation of the word "Inferno." Could you please provide more details about what you're looking for?

For example, you could clarify:

* What specific event or situation are you thinking of? Is it a battle, a special event, or a particular location?

* What kind of Pokémon or character is involved?

* Which season or series of the anime are you interested in?

With more information, I might be able to help you identify the episode you're looking for!
