Denso Developing Ethanol-Compatible Fuel Systems

Nikkei. Japan’s Denso is joining the ranks of parts suppliers such as Bosch and Delphi in developing auto fuel system components that are ethanol-compatible.

Toyota, Denso’s major customer, announced earlier this year that it will introduce E100-capable flex-fuel vehicles to the Brazilian market in the spring of 2007, and that it was “considering’ introducing flex-fuel vehicles to the US in consideration of policies to promote bioethanol fuels. (Earlier post.)

Furthermore, Japan is adopting a new national energy strategy designed to reduce the nation’s dependence on petroleum; one component of the new strategy is increasing the percentage of ethanol in gasoline from 3% (E3) to 10% (E10) by 2020. (Earlier post.)

Along with a fuel injection system designed for increased flow capacity to offset the lower energy generated by ethanol combustion, Denso is developing fuel system parts that can handle the corrosion and condensation that accompany ethanol usage, as well as sensors for measuring alcohol concentration.

The engine control software will need to be able to detect ethanol blends and adjust fuel and spark control to optimize efficiency.

I hope Toyota does introduce Flexfuel for ethanol, as well as diesel,(bio-diesel from algea is the best hope for mankind). Currently the only flexfuel vehicles are GM products, and they are all behemoths. Impalas, Monte Carlos, SUVs. What the hell GM? Have your top brass still not figured out that Americans want fuel economy? Toyota and Honda have the 2 highest CAFE and they are doing fantastic business while the Big Three flail about trying to pawn off their giant Trucks to a market that is demanding efficient vehicles.

Hell, one need only look upon GM's take on Fuel Cells, (their biggest excuse to not work on alternatives) to see the Detroit mindset.

GM's Sequel FCV, Which is currently drivable, is a Crossover SUV vehicle that gets 39 miles/kg H2, equivalent to 39 mpg. Not bad for a GM.

But look at Honda's FCX, which Honda will begin selling in 3-4 years, (no timeline on a GM FCV yet). This is a super sleek sedan that gets 70 MPG equivalent!

It is astonishing that GM has been working on FCVs since 1995 and yet still falls behind the Japanese, and they aren't even making the damn things available to the public yet!

Now GM is banking on FFV to save their asses, but the Japanese have them beat!

Honda is coming out with a small hybrid for $17,500, a 4 cylinder diesel, and now Toyota FFVs!

Detroit just can't compete! After all who in their right mind would choose a GM, legendary for its cheap interiors and crappy reliability, over the legendary quality of Honda or Toyota, who not surpisingly also get better mileage.

Pretty much what he said.
Also engine control software that can detect D/ biodiesel blends/quality to optimize fuel/ignition/emissions control.
fwiw Adam Im driving a fantastic 4cylinder GM diesel car and yes they needed to be here years ago.

You guys forgot about GM's divisions in Europe. For that matter, many overseas divisions are doing fine. The problem is US leadership/management and the strategic choices they made.

Fuel cell vehicles are the Potemkin Villages of the US Auto Industry. A hollow promise created to astound political royalty ;-)

Will any automaker prove this wrong by actually selling one? (no leasing games please).

Fred, please tell me what 4 cyclinder GM you are driving for I know of no such vehicle.
