Theory questions
Which statement is true regarding the fuel consumption per kilometre for a petrol-driven car with a catalytic converter after a cold start?
“The short distances cause the most pollution per km. […] Petrol consumption and carbon dioxide emissions are 35% higher in the first 5 km, as a cold engine requires a “richer” fuel mix. During the first 5 km, the average car will consume as much as 0.14 litres/km.” (Swedish Society for Nature Conservation)
Note that the question is asking about the consumption per kilometre, i.e. an average. Over a longer distance, you will normally use more fuel overall, but not in terms of average consumption per kilometre.
