Typisk fejl:
Learners often use "combustion" when simple "burning" would sound more natural in everyday speech (e.g., saying "The wood had a fast combustion" instead of "The wood burned quickly"). Another common mistake is treating "combustion" only as countable; in most general uses it is uncountable ("Combustion produces heat", not "A combustion produces heat").

Typisk fejl:
Learners may confuse "combustion engine" with "combustible engine"; the correct term is "combustion engine" because it describes an engine where combustion happens, not an engine that can burn. They may also say "engine of combustion" instead of the fixed phrase "combustion engine" or "internal combustion engine".
