Catalyst conversion efficiency against temperature.
| Bed temperature (C) | CO conversion | HC conversion | NOx conversion |
|---|---|---|---|
| 150 | 5 | 3 | 2 |
| 250 | 60 | 45 | 40 |
| 350 | 97 | 94 | 93 |
| 500 | 98 | 96 | 95 |
What does the table imply about short journeys?
Answer: B
Between 150 and 350 degrees the conversion goes from almost nothing to almost everything, and reaching that band takes a minute or two from cold. A five kilometre trip may therefore emit more than a fifty kilometre one.
