Our reaction is, get rid of that noxious 15 percent gasoline, then do the study over. Evaporative emissions increase when gasoline is added to ethanol. But adding ethanol to gasoline drops vehicle’s tailpipe emissions of CO2 substantially!
Running neat ethanol would result in a 90% drop in emissions over gasoline in even a simple conversion. A well-designed dedicated alcohol engine would actually emit cleaner air than the air entering the engine.
Vaporizing pure ethanol will increase mileage and cut emissions further. Vaporization can’t happen with gas because it burns at too many different temperatures.
Several energy corporation studies have indicated that alcohol exhaust contains high levels of hydrocarbons (HC) and nitrous oxides (NOx), with reductions in carbon monoxide (CO). However, the validity of the techniques that oil-company-sponsored organizations have used to measure HC and NOx is disputed in the scientific community.
And modern three-way catalytic converters strip all traces of acetaldehyde from the exhaust of a properly tuned alcohol vehicle
We don’t know if he used the MBTH method but it’s very unreliable, if so. We’ll have to look at the study when it’s posted today.
The ethanol/smog issue obviously needs further examination. Let me know what you find. Getting rid of the 15% gasoline is a great start.
