Results indicate that when
the ethanol content of the fuel increased, the emissions of gaseous organic compounds increased whereas the amount of aromatic compounds such as benzene and toluene decreased.
Even if
the ethanol content of the gasoline pool rises to only 28 %, it will mean that the number of vehicles using E85 must rise to 24 % of the vehicle fleet (versus 14 % originally forecast in 2007).
Even with this small increase in the share of natural gas powered vehicles,
the ethanol content of the gasoline pool could rise to 34 %, posing an even greater problem for the future viability of E10 and E85 gasoline.
Re: Joint opposition to petition from Growth Energy to increase the allowable
ethanol content of gasoline to 15 volume percent.
This damage is unnecessary and can be avoided by freezing
the ethanol content of gasoline at 10 % by volume.
Plan 4 is the sneaky plan to increase
the ethanol content of gasoline to the point where it will destroy many old cars and force people into buying new cars that the EPA considers green, such as the Chevy Volt, Toyota Prius, Nissan Leaf, or at the very least, more fuel - efficient gasoline powered cars that pollute less and will run on E15.
The latest Porsche models with a petrol engine are designed to operate on fuels with
an ethanol content of up to 10 %.
Not exact matches
This methodology has been fully described by others (e.g., Lachenmeier et al., 2010) and provides a model protocol for evaluating the
ethanol content and safety
of unrecorded alcohol products.
«The idea is that a small reduction in alcohol — such as beer with four per cent
ethanol content versus six per cent — would reduce alcohol intake per drinker even if the same overall amount
of beverage is consumed,» says Dr. Jürgen Rehm, lead author and Director
of the Institute for Mental Health Policy Research at the Centre for Addiction and Mental Health (CAMH) in Toronto, Canada.
Thus, it is reasonable to conclude that it is not the carbohydrate
content of the diet but
ethanol per se, when administered chronically, greatly impairs the glycosylation machinery
of rat liver and that the magnitudes
of these effects are selectively specific with regard to the type
of sugar or the glycosylation enzyme
Our results clearly showed that regardless
of the carbohydrate
content, marked decreases in the incorporation
of labeled sugars into transferrin and the enzymatic activities
of galactosyltransferase and sialyltrans - ferase occurred in rats administered chronic
ethanol.
The fitness industry has long had a negative stance on alcohol consumption due to its lack
of nutrition (empty calories) and
ethanol content, the toxic metabolic by - product that can cause damage to your liver and inhibit essential nutrient absorption like amino acids and B vitamins, while also impeding upon muscle protein synthesis.
(Pure
ethanol has an energy
content of 84,530 BTU / gal, whereas standard gasoline has around 120,388 BTU / gal.)

ethanol» is part
of the paid WardsAuto Premium
content.
A gallon
of ethanol has a lower energy
content than a gallon
of gasoline (as measured by BTU
content).
The gasoline also did contain some hydrogen that burned to form water, so the 3:1 ratio Jeff references probably was for gasoline (not containing
ethanol) but adjusted for the mass
content of the hydrogen in the gasoline and is likely more accurate than the 3.67 ratio
of carbon to carbon dioxide masses.
One million gallons
of cellulosic
ethanol has the same energy
content as half a million gallons
of crude oil.
That flies in the face
of the serious market distortions now manifesting in the «blend wall» at 10 %
ethanol content in gasoline.
When that is adjusted for
ethanol's lower energy
content, it means
ethanol will displace only 1.8 %
of total U.S. oil imports in 2015.
The bill would eliminate the current mandate to blend 15 billion gallons
of corn
ethanol into fuel by 2022 and ban
ethanol fuel
content over ten percent.
According to the Energy Information Administration, the energy
content of ethanol is about 33 % less than pure gasoline, and E85 contains 51 - 83 %
ethanol, lowering gas mileage and forcing consumers to fill up more frequently.
If you look at a flex - fuel car, it will have all fuel related parts made
of materials designed to withstand the corrosion effects
of the higher
ethanol content.
If the
ethanol mandate in the Renewable Fuel Standard (RFS) required more, then you're running into the
ethanol «blend wall» — that is, to satisfy the RFS, refiners would have to blend fuel with higher
ethanol content than millions
of vehicles are designed to use.
Fig. 2 (right axis) shows the expected percentage
of ethanol content in the future gasoline blend pool.
Anyway, the lower energy
content of ethanol IS accounted for in this vehicle example.
At this production level, corn - based
ethanol would replace about 10 %
of the volume (or about 7.2 %
of the energy
content)
of the US gasoline supply.
Because
of the difficulty you seem to be having understanding the implications
of «total liquid fuels», «net energy», and «lower energy
content of ethanol.»
