Desde pequeninhos no habituamos a exaltar os importados, principalmente na
área tecnologica. Isso não foi sem razão claro, montaram uma industria
sanguesuga (que de tão bom negocio é hoje praticamente de capital
estrangeiro) que sempre vendeu produtos defasados (projetos estrangeiros...
se ao menos fossem defasados genuinamente nacional mostrando que existe
investimento solido em pesquisa...) e de baixa qualidade para um mercado
que se tornou cativo na marra ou as custas de um paredão de impostos
alfandegarios.
A reportagem saida hoje e que reproduzo abaixo, explica aos americanos o
que é o motor Flex, que agora estão começando a serem introduzidos no
mercado do país meio que na surdina... Notem duas coisas, não é mencionado
que o Brasil já possui e usa essa tecnologia a alguns anos e nem tão pouco
o embuste que é o alcool etanol extraido do milho (que segundo recentes
estudos da MIT gasta mais energia para ser produzido do que gera, ao
contraio do alcool produzido a partir da cana de açucar... basta pensar na
quantidade de liquido que possui um pedaço de cana e uma espiga de
milho...). Portanto, de vez em quando, ao menos, no campo tecnologico,
saimos na frente... Mas, pera aí... essas montadores de automoveis não são
todas elas multi-nacionais??? Agora entendo porque não fizeram alardes
ufanistas do motor flex... estavam usando o consumidor brasileiro de
cobaia... Felizmente, dessa vez, deu certo.
Fica a dúvida em relação a patente do sistema Flex... quem é ou são os
bilionarios? Outra seria em relação a quando é que vão lançar um hibrido
Elétrico-Flex...
Flex-Fuel FAQ
You might be driving a flexible-fuel vehicle
By JAMES R. HEALEY, USA Today
Flexible-fuel vehicles are seen as a way to cut our use of gasoline because
they can run on a fuel that is mostly grain-based ethanol distilled in the
USA from corn. USA TODAY reporter James R. Healey answers some common
questions about flex-fuel vehicles.
Q: What is a flex-fuel vehicle?
A: It's an ordinary car, truck or van that's been equipped with a special
fuel system and engine-computer programming that allow it to burn straight
gasoline, E85 or any mix of gasoline and ethanol in between. E85 is 85%
ethanol -- grain alcohol -- and 15% gasoline.
Ordinary vehicles can safely burn a mix up to 10% alcohol -- often called
gasohol and sold widely. But you risk ruining a conventional vehicle if you
burn E85 or any mix that's more than 10% ethanol. You need a flex-fuel
vehicle to use E85.
Q: Why would I want one?
A: You might not. The point of flexible-fuel vehicles -- FFVs -- is to use
E85 as a way to reduce dependence on oil and to redirect the money that we
spend on fuel to American agriculture interests and away from often-hostile
foreign fuel suppliers.
Though the number is growing, E85 is available at only 600 or so of the
170,000 service stations in the USA. Most are in the Midwest states that
grow the corn from which most U.S. fuel ethanol is made.
Q: So I should avoid an FFV?
A: You might not have a choice. The FFV capability is standard on a number
of vehicles. If you buy one of those, it's an FFV. Period. But you never
need to use the flex-fuel capability. You can burn conventional gasoline,
and it will run the same as any gasoline-fuel vehicle.
Q: Will it cost more to maintain an FFV?

A: Not if you burn gasoline. If you use E85, it might. Check the owner's
manual carefully to see if it calls for different oil or different service
intervals. It's unlikely there will be big differences.
Q: Should I be worried about the reliability of this newfangled technology?
A: Probably not; it's not newfangled. The U.S. government credits Ford
Motor with creating FFV technology in the mid-1980s.
Automakers have put roughly 5 million FFVs on the road since then. In many
cases, their owners have no idea they are driving FFVs because they look
the same as any other vehicle and drive the same as conventional vehicles
when using gasoline as fuel.
The government lists 21 different 2006-model FFVs -- more if you consider
the two-wheel-drive version of a truck different than the four-wheel-drive
version. Most are midsize or big cars and trucks. You can find the list,
and the fuel economy of each model, at www.fueleconomy.gov.
Additional FFV models are being introduced this year, some as 2007 models,
and those aren't yet on the government's list.
Q: I don't want to pay extra for the FFV feature if I won't use it.
A: You won't pay more, at least not overtly. Automakers include the FFV
capability as a standard feature on the vehicles that have it, or offer it
as a no-cost option. There's not a separate line on the window sticker that
says, "FFV capability $300," although it can cost a car company that much
for the special fuel tank and fuel lines and the bigger fuel injectors
necessary to cope with alcohol's corrosive nature and lower energy content.
Of course, the base price of the vehicle might have been boosted to recover
the costs.
Are You Flex-fuel Friendly?
Q: How does the lower energy content affect the vehicle?
A: It reduces fuel economy, so you'll have to fill up your tank more often.
The U.S. Department of Energy says it takes 1.4 gallons of E85 to go as far
as you can on one gallon of straight gasoline. That means that E85 has only
72% as much energy as gasoline does.
For E85 to be a financial wash with gasoline, you have to be able to buy it
for only 72% as much as you would pay for gasoline.
Government fuel-economy ratings show the mileage hit clearly. A Chevrolet
Impala equipped with the 3.5-liter V-6 engine is rated 21 miles per gallon
in town on gasoline and 31 mpg on the highway. On E85, it's rated just 16
in town, 23 on the highway.
The blessing, of course, is that if you can't make it to the next E85 pump
before you run dry, you can simply fill up with conventional gasoline. With
a full tank of conventional gasoline, your FFV goes back to delivering its
maximum mileage.
The engine-control computer helps compensate for some of the power drop-off
you'd expect from fuel that has a lower energy content. But the engine
computer usually can't completely make up the difference.
Pro-ethanol websites often minimize the power and fuel-economy differences.
If you're surfing the Web to learn about FFVs, check a number of sites to
make sure you're getting a variety of voices.
Saab sells a model in other countries that retunes itself to take full
advantage of E85's higher octane -- 100 to 105, vs. 87 to 93 octane for
gasoline. Called the Saab 9-5 BioPower, its turbocharged engine develops
150 horsepower on gasoline, 180 hp on E85. But it still gets worse fuel
economy, Saab says.
General Motors, which owns Saab, is considering a U.S.-market version, but
"It could be a couple of years," says Saab spokesman Tom Beaman. A
prototype, displayed at recent auto shows, is rated 260 hp on gasoline, 310
hp on E85.
Beaman says it probably would get 20% worse fuel economy on E85 than on
gasoline.
