Friends: 0 |  MPG and evaporative recovery One of the things I'm wondering about that will produce a systematic MFD mpg error is the quantity of fuel that ends up entering the combustion chamber other than through the injectors. The primary source would be evaporative emissions trapped by the canister, etc. that will bypass the injection system, entering with the air stream. Does anybody have a good source that quantifies this for some standard model? I'm wondering what the magnitude of the effect is. |

Friends: 12 | Re: MPG and evaporative recovery That's a good question. There is a carbon/charcoal adsorbing filter in the air cleaner housing to presumably capture the vapors |
