Default CGI Propels Diesel Engine Designs Forward

Super Nice educational read on the lastest developments in turbodiesel engines!!! [img]images/icons/grin.gif[/img]

Over the past five years, diesel engines have become more and more powerful, and of course the way to make an engine more powerful is to make the combustion more severe. So they pump in more fuel, they explode the fuel at a higher pressure, and they get more performance out of the engine. As a consequence, they also get higher fatigue loads down at the bottom of the engine.

In 1997, the state-of-the-art for performance was approximately 40 kilowatts per liter; by 1999 we were up to 50 kilowatts per liter. The engines that are now being designed for release in 2004 are at 60 kilowatts per liter, and we're already involved in new development programs for 2005-2006 that are targeting 65 kilowatts per liter. So if you look at a typical two-liter diesel engine, the performance has increased from something like 80 to 120 kilowatts (105 to 160 horsepower), or by 50% in the last five years.

Thanks, SkyPup. I got the most out of page 6 where it basically said diesels in the U.S. won't take off until ULSD. The real question is whether 2004 CARB Tier II requirements will effectively kills diesels from 2004 til 2006/2007. The TDI you drive today or purchase before Tier II goes into effect will have to last you until 2006/2007, I think. This is so sad. All because an EPA study linked particulate matter with cancer. Well, you know what, exposure to the sun causes cancer, too. Why don't we just cover our cities in opaque domes !! Damn EPA and CARB got it so wrong on this one.

All of North America is waiting for ULSD in 2006 as it will enable the proper diesel engine technology to take care of the remaining problems with diesel emissions.

Engine technology does not advance without fuel technology, they are both interdependent on each other 100%! [img]images/icons/smile.gif[/img]

The main reason for the delay is the bad diesel offered in the US. With a good quality the dieselemissions can be cleaner than those from petrolengines. The high sulphurcontent is killing the new hightech highpressure injectionsystems and particularly the particletraps that are used by some OEMs. The latest hightech super-high-peak combustion pressures seems to handle the particles without traps. They are eliminating them already in the combustionchamber. With the current sulphurcontent you can say that the whole US is trapped in a particletrap.

With a decent diesel share among US cars ( like Europes 40 % ) is would save TWICE as much crude that is imported from Iraq equal to some 700.000 barrels....per day..

It might have turned out to be a much healtier way to deal with that independency problem. But somebody else knows better.

So help you God.

Yes, almost all of North America is in the dumps due to the crummy diesel fuel quality [img]images/icons/frown.gif[/img]

It is truly a national disgrace, especially compared to the extremely high quality diesel fuel technology you have enjoyed there in Sweden for over a decade now....... [img]images/icons/frown.gif[/img]

maybe by 2020 we might start to catch up a little bit..... [img]images/icons/rolleyes.gif[/img] [img]images/icons/shocked.gif[/img]

Then again, the true lack of any consumer appeal for any high economy passenger cars has alot to do with it.

Even a 2002 $2,000 tax break for purchasing a hybrid did little to raise their sales.

However, the true fact that is that the automaker makes $5,000 profit off every SUV, and up to $20,000 profit off every loaded high end SUV like a Navigator or Expedition, that shows you where the sales and marketing hype will all be pointed.

Despite what the conditions may seem to be, marketing for the upper-crust sport ute's is very small. These models sell themselves...marketing exists for the loss-leaders, those cars sold at a loss to bolster the CAFE.

Only a fixed number of the highly desirable SUV's can be built each year in order to comply with CAFE. To raise the CAFE, more small-medium units have to be sold...but since no one want these, prices are discounted deeply, often to the point of a net loss. The "insane" profits made from the SUV's balances out this loss.

People drive what they want to, not what Detroit gives them. I remember back in the late 1970's when big families were considered trendy if they had conversion vans...having a station wagon was...well...dorky. Now a minivan is dorky...even a conversion van is that way in a sense.

Fashion. That is the real problem. Its like the 70's when bell-bottoms were in.

True, but now the fashion statement is a 5,000 lb SUV that gets less than 15 mpg and is the producers main profit margin.

After getting our taxes in order this weekend I noticed the Toyota, Honda hybrid tax deduction subsidy from the Feds, too bad they don't do the same for turbodiesels.

Wait a minute. Aren't the SUV's exempt from the CAFE standards? Big Auto can sell as many SUV's as they want, no?

Not quite. From what I understand, the automakers have to have a certain AVERAGE for the fuel economy. So, therefore sell a lot of smaller cars with good fuel economy to be able to sell a bunch of SUVs with poor economy. Damn loopholes.

The "light truck" CAFE is 20.7 MPG. The "cars" CAFE is 27.5 MPG. Guess which kind of vehicle an SUV is ?

An amusing Light Truck anti-CAFE article. This is my favorite quote:

"Ongoing technological improvements may boost mpg ratings somewhat, but not nearly to the 26-28 mpg level. "

I guess this guy's never heard of diesel.

Sorry if this question is a bit off subject, but I would appreciate any ideas from this group on an idea I've been thinking about recently--would it be feasible at all to put a TDI engine in one of the new Gas-Electric Hybrid cars that are out (Prius or Civic or the soon to come out Ford Explorer)? I don't know a lot about this stuff, but couldn't a diesel hybrid get some pretty big fuel efficiency #s? Would this be at all doable--i.e., could a TDI engine "fit" any of the existing hybrid vehicles, be mated to both the electric motor and CVT transmissions in these cars, and would this be legal in CA?

I tried to post this question on this forum as a new topic, but don't seem to have the permissions to do so, so sorry if this is too far off this conversation.

Thanks,
Elan

Anything is possible. All it takes is a lot of money!

The problem is it wouldn't be legal. If the vehicle didn't have a diesel engine from the factory, it is not legal to put one in it.

I believe you missed his point. To start the debates about the
motivations of Big Auto in the US once again, why would you
pair an inherently less efficient gasoline engine with an electric
motor, as opposed to an inherently more efficient diesel engine?

However, I believe this question has been addressed; see the thread
on the new Toyota 87 mpg diesel hybrid, also in this forum.

Another clear sign that CGI is here to stay.

Market Development

The SinterCast System 2000 installation at the Teksid foundry in Crescentino, Italy, is being used for the
production of CGI cylinder heads for Iveco marine engines. The CGI heads, which have the same design as the
original alloyed grey iron cylinder heads, were tested during the second-half of 2002 in the demanding Italian
Carabinieri police boat application. The successful performance of the CGI heads, <font color="red"> including more than 100% </font>increase in service life, , has resulted in the cylinder heads of the entire Carabinieri marine fleet being converted to
CGI. The performance of the marine engines, which are a derivative of the standard heavy-duty truck diesel
engines, is providing valuable CGI experience to both Teksid and Iveco.

In conjunction with the opening of Ford's new Diesel Engine Centre of Excellence in Dagenham, England,
scheduled for late 2003, SinterCast and Tupy have been invited to make a CGI technology display in the lobby of
the new facility. The multimedia display will focus on the application of CGI to the 2.7 litre V6 Lion engine and
will address the foundry and manufacturing solutions for high volume CGI production as well as the technical and
environmental benefits of CGI in internal combustion engines. Together with Tupy, we are pleased to be one of
only three new-technology displays invited to the Diesel Engine Centre of Excellence, the facility that will house
Fordís Diesel Engine Engineering Team and the production of the Lion engine.
