Here are the new specs for the VW TDI diesel engine: CC--1896 HP--100 at 4000 RPM Torque--177 at 1700 RPM Fuel Mileage 49 MPG on highway in 2700 lb car. Can we get this in a Buell? | ||
| Johnk3 |
I have a TDI and I get 700miles per tank... that would be nice in a buell too | ||

and if ya want hp.as well as torque check out the 1.8 turbo VW 200 ponies and not sure about the torque but its up there all out of a 1800 cc`s and same weight as the diesel ,gas mileage is 45 miles per gallon not bad eh... | ||

Just buy the Y2K bike tuned to run on Diesel. I think that would fill your torque addiction. | ||

Our 2000 Beetle TDI has gotten 53 mpg on the highway and is rated at 90 hp. Although it's fun to drive it doesn't even approach the fun factor of my XB12R. Diesel engines have heavy internal components and rev lazily compared to gas engines, and although they are about 8-10 % more efficient on average they always weigh more. How would you like your rev limiter to kick in at 4500 RPM? How about the extra heat from the turbo cooking your leg on a sunny afternoon? It's kind of a silly comparison IMO. If you want diesel performance and mileage on a motorcycle you should try to get a copy of the KLR that Kawasaki built for the military. I think it gets somewhere close to 120 mpg. You'd be lucky if you could get it much past legal highway speeds | ||

If its gas mileage you all are seeking Buy one of them 1960 models Honda 50cc`s :-)) | ||

I'm a big fan of diesels. My diesel pickup (crew cab 4x4 3/4 ton long bed) has 300hp, weighs 7,000lbs, and gets 19-20mpg. I can touch a button and raise the power as high as 420hp, in 5 steps. Rev limiter is 3200 rpm. The motor lasts a long time because it doesn't turn very high. I'm paying 1.73 for diesel right now. Gas at the same station is 1.95. I wish there were more diesel vehicles available in the U.S. They're much more common in Europe. I switched to diesel pickups in 1992. I'll never own another gas powered pickup. The diesel just kicks it's ••• in all areas. I'd buy a turbo diesel motorcycle, in a heartbeat. It could be done right. There's no reason they need to have less power than a gas powered bike. I'd love to run it on bio-diesel. But it's hard to find and expensive. Also, everything I've read so far is that commercially available bio-diesel has high water content, which is bad for injectors. Still, if they get the issues sorted out and get the price into the same ballpark, it'd sure be the hot ticket. The motors run better and cleaner. | ||

There was a diesel that ran Le-Mans this year. They were doing "well" but they kept frying clutches. They were on par with HP but something like 2X-3X the torque. | ||

Diesels pollute the air. I'm sick of them. They're fine if someone uses them for what they're designed for- hauling loads on the freeway at a steady constant RPM. Most people don't even need a diesel. Diesel fuel costs here actually went higher than regular gasoline for awhile. What's the deal with people racing diesel trucks? I'm so sick of diesel trucks racing and blowing their stinky, foul black smoke out into the air for everyone to breath. A lot of times they do it on purpose to people walking on the sidewalks. It's so pathetic. Why would you want a turbo diesel motorcycle? It would be heavy and complicated. Maybe if you wanted to tow your camper trailer around with you. Diesels arn't that great, except in semi-trucks, generators, ships, diesel-electric locomotives and the occasional farmer that hauls big trailers and needs one. | ||

They're good in earth movers too. | ||

984_CC, You don't have any feelings on this diesel subject do you?  kk//kef | ||
| 984_cc |
Who?... me??...nope not me.  | ||
| M1combat |
Interesting... What about 2-stroke diesels? I have one at home that runs up to 40K RPM's on nitro fuel. Isn't the new diesel fuel supposed to clean up a lot of the pollution from them? Admittedly, I don't know much about diesel engines (other than how they work). Please enlighten me as to exactly why they are such a horrible idea. Unless of course if you mostly feel that way because you get some smoke blown on you when walking to work... | ||

984cc: More emotion than fact my friend. Now calm down and tell us how you really feel.  | ||

I believe Rudolph Diesel (the guy who invented the diesel engine, I think around 1890), originally had intended the diesel to run on biofuel. I have heard that the switch to using biofuel could be done quite readily. It would clean-up the exhaust emissions a great deal. The new direct-injection diesels are cleaner and more efficient than older diesels, but they are still very dirty engines compared to gas burners. I don't hate diesels, just hate how people use them for the wrong purpose. Our air pollution has gotten so bad here in the last few years because of consumer diesels, and racing them down the street doesn't help either. I have heard about 2-stroke diesels before. EMD (Electro-Motive Division, General Motors) use to use 2-stroke diesels in their locomotives back when they (diesel locos) came out in the late 30's, 40's and 50's. I don't think they are very common nowadays, but I could be wrong. Is your diesel a R/C airplane or car engine? I've seen the conversion kits to convert the glow-plug 2 strokes to operation. | ||

...convert the glow-plug 2 strokes to DIESEL operation- (my last sentence) | ||

Diesel Engine & Emissions Diesel engine is the most efficient power plant among all known types of internal combustion engines. Heavy trucks, urban buses, and industrial equipment are powered almost exclusively by diesel engines all over the world. In Europe, diesel powered cars have been increasingly popular. The diesel engine is a major candidate to become the power plant of the future. Before that happens, however, further progress in diesel emission control is needed. Internal combustion engines are significant contributors to air pollution, which has a damaging impact on our health and the environment and is suspected to cause global climate changes. Environmental benefits of diesels, such as low greenhouse gas emissions, are balanced by growing concerns with emission of nitrogen oxides and diesel particulates. Increasingly tighter environmental regulations worldwide call for advanced emission controls and near-zero diesel emission levels in the years to come | ||

BTW- I have ridden near VW diesels and they don't smoke nor smell. Not to be confused with Diesal trucks. Diff technology I assume. | ||
| Hogs |
HEy Brucelee VW Diesels Do smoke and SMELL hahahahahah I sell em and believe me they smell and smoke just some more than others..Brand new ones on the lots Smoke upon start up and the older they get the more they Smoke.. | ||

Yes, it's an R/C engine. .15Ci and makes over 2HP (I think it's 2, maybe it's four?). It was diesel when I bought it. IT doesn't run diesel fuel, but ignites via compression and runs a glow plug. It runs my little 4WD truck up to about 60Mph (clocked by the local Police). The entire engine has three moving parts, four if you count the carb... | ||

Run 'em on Biodiesel and its a whole different story on almost all counts (smoke, smell, emissions). Go google it sometime there are some independent tests out there that are easy to find and make a great case for running diesels and specifically on biodiesel. | ||

"I believe Rudolph Diesel (the guy who invented the diesel engine, I think around 1890), originally had intended the diesel to run on biofuel." Yep...Hemp oil. | ||

Actually M1, glow-engines are not 'diesel'. They require the glow plug to run. If your glow plug burns out, It won't run. The 4-stroke R/C engines use a glow plug too. A misconception about diesels is that they require glow-plugs to run. However, many diesels don't even have glow-plugs. My dad's 1969 JD 400 backhoe is one example. Glow-plugs are used for extremely cold weather conditions, when the diesel is very hard to start if glow plugs are not present. Once the diesel is started, the compression combustion takes over and the glow plugs are not needed. There are kits that you can buy to convert R/C nitro engines to burn kerosene. You install a very high-compression head on your engine. The ones I have seen have to be adjusted once the engine is running by screwing the head in or out to adjust the compression ratio. | ||

I think the VW driver has a different attitude than the average big diesel truck ahole. The VW driver isn't modifying his vehicle to make it less efficient and more dirty. He/she also doesn't floor it all the time everywhere they go trying to prove something. Brucelee- What does that mean- most efficient? In fuel consumption or output? Mazda's Renesis Rotary (normally aspirated) is just 1.3 liters and puts out nearly 250 HP. The 2-stroke moto-cross bikes put out alot of power. The RM80 put out 27 HP- that is 337.5 hp/liter! Now, what upsets me is the way alot of people are using their trucks. They don't get good fuel mileage racing them. Diesels are good at working under constant load at a steady RPM. That is when they are most efficient. Particulate 2.5 is a deadly cancer causer. It comes from diesel engines burning diesel fuel. I heard that the biofuels even increase power besides being cleaner. | ||

"Brucelee- What does that mean- most efficient? In fuel consumption or output?" I believe the author meant in terms of MPG (ie extracting energy from the fuel). As I understand it, the diesel engine technology is continue to evolve and get more sophisticated. They have scrubbers in the works that will remove that last remnants of pollution. And then there is biodiesel. Good stuff. | ||

Do be honest, I think the internal combustion engines of the future will be burning Hydrogen. And to be more specific- the rotary engine will once again take the title of the 'Engine of the Future'. Why?- because Hydrogen is much more prone to pre-detonation than gasoline. A reciprocating piston engine develops hot spots on top of the piston. These hot spots can produce pre-detonation . The rotary engine does not develop hot spots. It is a perfect candidate for Hydrogen fuel, although a reciprocating engine can be made to work also. Mazda is working on a Hydrogen powered car using their Rotary engine. Other companies are working on Hydrogen power too. BMW is working on a V8 model. I believe I read or heard somewhere, but I'm not sure, that BMW and Mazda have teamed-up to work together on this, since they are at the forefront of the technology. Wouldn't it just be so cool to have a V8 powered hotrod and it's only emission was water vapor? I think that sounds better than just wimpy Hybrids. Pure electric motor driven vehicles should be fun too, since electric motors make max torque at zero RPM (like a steam engine does). The electric motors are getting more powerful and cheaper to produce. | ||

Here you go- 6300 BHP @ 1000 RPM. Perfect for doing WORK! This one is a 4-cycle. They still make 2-stroke engines too. http://www.gmemd.com/en/locomotive/innovations/engine/Hengine/index.htm | ||

I like trains, ships and earth-moving equipment BTW. So that EMD Prime Mover is quite fascinating. | ||

Rotary engines: great hp/wt ratio, crappy torque. You'll never see one in a vehicle larger than a compact car. | ||
| 984_cc |
Crap. True, their torque isn't as great as a V8, but it's better than a Honda. Especially if you turbocharge them.- 217 lb. ft. torque out of the last RX-7 (still 1.3L, 2 rotor) sold in U.S. In Japan they recently just stopped making the RX-7. They had it significantly upgraded in power from the old U.S. RX-7(255 HP, 217 lb. ft.). They were rated at 280 (underrated) HP and the torque was also increased but I can't remember the spec right now. The Cosmo 3 rotor (2.0 liter) had 280+ lb. ft of torque. Rotaries can be pumped up to well over 600 HP and 500 lb. ft. of torque. The RX-8 is certainly not a compact. I don't think you have driven a rotary powered car before. 280 lb. ft. of torque is great from just 2.0 liters. |
