Honda's 2.2-liter i-CTDi diesel engine  (Source: Honda)

2008 Honda Accord EX Sedan  (Source: Honda)
Honda readies its diesel engines for passenger vehicles in the U.S.

DailyTech reported in early June that Honda's newly redesigned Accord would receive a diesel engine. Honda today confirmed that the 2009 Honda Accord would be available with an optional 2.2 liter i-CTDi 4-cylinder Tier 2 Bin 5 diesel engine.

The diesel engine is reported to produce in excess of 150 HP, while torque -- always a diesel strength -- is pegged at 260 lb-ft. The diesel will be emissions legal in all 50 states and is set to deliver real word fuel economy in excess of 40 MPG.

If the fuel economy estimates pass the Environmental Protection Agency's testing, that would make the diesel Accord more fuel efficient than the previous generation Accord Hybrid and Toyota's current Camry Hybrid.

The 2.2 liter diesel is expected to be closely followed by a new 3.5 liter V6 diesel destined for Honda's large vehicles. The engine is 30 percent more fuel efficient than the current 3.5 liter V6 gasoline engine used in the Odyssey, Pilot and Ridgeline according to the Nikkei newspaper.

In addition to the diesel news, Honda also announced that the CR-Z hybrid concept will make it to production. The small two-seater uses the same powertrain as the Civic Hybrid (4-cylinder gasoline engine, Integrated Motor Assist and CVT) and is likely to better its 40 MPG/45 MPG city/highway EPA ratings.

The CR-Z will be accompanied by a $22,000 five-seat Global Small Hybrid (GSH) which will do battle with Toyota's Prius in 2009.

I can play the numbers game too.

Number of barrels of gasoline consumed in one day by America (2006) = 9,159,000

Number of bushels of corn produced in one (record) year by American farmers (2004) = 11,800,000,000

Number of barrels of ethanol that can be produced from that corn (83:1) = ~142,000,000

Number of days until all the ethanol is gone and the US has completely exhausted its domestic corn supply = 15.5

you can plant more corn in the short and long run. let me see you "plant" more crude in the long run.

Can you plant more water? Each ethanol plant consumes 2 million gallons of water per day.

Ethanol as a "filler" makes some sense (as in the 10% in all of gasoline now) to take the edge off of gasoline use. This also applies to bio-diesel like B20. However, the idea of running E100 is not practical.

then I take it you agree with both processes. why complicate matters with a two step process? why not just simply matters, saving the trouble of finding an alternative source once crude has been depleted?

I support more efficient means of transportation AND alternate fuels as a complete approach.

Converting the soccer mom's H2 to straight E100 makes zero sense. Dropping in a fuel efficient diesel or even hybrid-diesel into the H2 actually saves fuel resources.

Even better would be for soccer mom to trade in for a diesel CR-V that gets 40mpg.

We're also forgetting that ethanol contains less heat energy. So we would actually need more barrels of ethanol to get the same mileage. I think we need to face the facts and admit that liquid fuels are on their way out.

As soon as you find the resources (manpower, land, and others) to support a twenty-five-fold increase in corn production, by all means - let me know.

(Remember, we need to feed ourselves too.)

Whew! You scared me at first!

Not contesting the numbers you threw up, biodiesel production of corn oil is 6 time more efficient than diesel production. (http://www.eia.doe.gov/kids/energyfacts/sources/no... A barrel of crude only gives 7 gallons of diesel, whereas to fill a barrel with corn oil is a whole 42 gallons.

Furthermore, your solution of 15.5 is the number of days corn supply TO MAKE a barrel of corn oil, NOT the number of days to exhaust a corn reserve. To compound your miscalculation, 15.5 can be reduced by a factor of 6 since a barrel of corn oil is 42 gallons, not 7 gallons, like diesel. 15.5/6 = 2.6 days corn supply.

We need to increase our corn production 2.6 times to satisfy the increase biodiesel use of corn.

I like you Peredun. You made me sit on the edge of my seat.

He didnt quote the number of crude barrels consumed, and he wasn't talking about corn oil, or bio diesel, he was talking about ethanol.

Diesels can be made to run on tar if you know what you are doing,thus requiring much less refinement of the fuel.

What I would like to see is the amount of energy that the sun puts down onto the surface of the earth defined by some unit area, and then compare that to current energy use. Combine that with the efficiencies involved, and the acreage of farmland and voila. Thats where all this junk needs to start.

The energy source is the sun, all of our "renewable" energy solutions would require that the daily balance of energy consumed is not greater than that converted from sunlight. Should be pertty easy to weed out the viable options from there.

I think that kind of analysis is why the defense department is looking at space based energy collection.

This article isn't just blowing smoke. They might be looking for proposals in the next 2 years to begin technology demonstrations. If bio-fuels were a viable energy option I believe the defense department would be investing in developing powerplants based upon using it and
better methods for its creation.

dude! stay with us. we have enough attention deficit people flocking (and writing) on Dailytech.

Yeah, and there's this thing called a "growing season" too. It's not like Iowa can grow corn in January!

We also feed livestock corn as well.

So in an effort to provide a slightly cleaner burning fuel at a cheaper price than oil, you want to clear cut vast amounts of new farmland and raise the price of corn.

Also , 15.5 days of fuel from a record year of production, that completely discounts the fact that a lot of that corn still needs to be eaten. Just how much more corn do you think we could plant. Even if we clear cut every square mile of land available and used slave labor.

That doesn't add up. If all gasoline sold in the US is 10% ethanol, and not all corn produced in the US is used to manufacture ethanol, then how is that figure possible?

In other words, we must already be producing enough ethanol to provide for 36.5 days of fuel (10% of 365 days,) right?

Now, I don't think ethanol provides nearly the same amount of energy per barrel as gasoline, but that's another discussion.

In hindsight, I suppose we could be importing corn and/or ethanol. Duh.

We are. And rainforest around the globe is being slashed and burned to provide the global corn market what it wants at record prices.

How the hell is that an acceptable "green" solution?

No idea. I was only questioning the math behind how much ethanol we could currently produce, not whether it's a viable solution or not. However, I doubt that ethanol has raised the demand for corn that significantly. In Brazil, where they are slashing the rain forest, it's not mostly for ethanol. To my understanding, it's due to the rising meat export market in Brazil and providing feed for the livestock.
