This used to be the case with fuel injected engines from 80's to 00's but because of new regulations current ECUs might, again, inject fuel while coasting just to keep the catalytic converter warm and operational.
The amount is obviously negligible but it's quite crazy to spend more fuel in order to reduce emissions :)
- Retric 10y agoSmog is a real health issue, and US city's are vastly better now. So, IMO it's well worth a tiny bit more global warming.

- justin66 10y agoThis is interesting. How do hybrids handle this? Use electricity to warm the converter?

- mikepurvis 10y agoEmissions per mile, miles per gallon, capital cost. You can only optimize two of them.
- mmagin 10y agoI suspect they just put a sensor there and inject fuel if it cools too much. For short coasting it's probably not a problem.
