⛽ What exactly is Kraftstoff?
Der Kraftstoff (plural: die Kraftstoffe) refers to a substance that releases energy through chemical or physical processes. This energy is then used to power machines, especially engines (e.g., in vehicles). So, it's essentially the 'food' for many engines.
Typical examples include Benzin (gasoline/petrol), Diesel, Kerosin (kerosene), but also gases (LPG, CNG) or Wasserstoff (hydrogen) belong to this category. The term is closely linked to the idea of Kraft (power) and movement.
⚠️ Note: Sometimes the colloquial term Sprit is used, but this is more informal.

- Technical context: In engineering and science, the term is used precisely for energy carriers used in internal combustion engines, rocket engines, or other machines for energy conversion.
