What is required to convert the USA to Diesel?

[brewnog]

I'm starting this up in Engineering, but if it starts to go that way then perhaps Russ or Enigma could move it to the Politics forum? Before that happens I'd first like to bottom out technical issues.

The question:
What would it take to convert the US (and Canadian) automobile markets to having anything like the same proportion of Diesel vehicles as Europe?

Diesel cars now account for almost half of all new vehicle sales in Europe. In France, demand for Diesels is almost double that of equivalent petrol powered vehicles. A Diesel Ford Focus will now develop more power and torque than a petrol version of the same displacement. It will also cost far less to run.

What are the constraints on the US market? Are we dealing with tired misconceptions about Diesels being sluggish, crude and noisy? These are definitely preconceptions which created a lag period in Europe between the creation of quiet, torquey, refined Diesels and the massive sales ramp which followed, I'd like to know if these preconceptions are still around in the US?

How about emissions legislation? While Diesels are far better for the environment in many ways, is the Californian legislation precluding the widespread sale of Diesels, and if so, is this because of the lack of availability of low sulphur fuel?

What will come first, a useable infrastructure network of low sulphur fuel, or a surge in demand? Will Diesels ever make it to market in such numbers as have been seen across Europe?


Thoughts please!

 

[Mech_Engineer]

They need to start taxing the crap out of gasoline like they do in Europe. that would do it

 

[Artman]

They did have a bad rep early on in the USA. Early diesel cars such as the VW rabbit, while being extremely high mileage, were noisy, rough running, sluggish and hard to start in cold weather.

Now I think the first cost is the main objection (in a pickup type truck an optional diesel engine can cost $4000.00 more).

Hey Brew,

You are ABSOLUTELY right. I live in CA, and Diesel is a forbidden word. You will see diesel fuel in a very few gas stations, and it is very expensive, much more than gasoline. I don't truly understand how this people run these SUV and pick ups with gasoline. It would be unthinkable to do so in Europe. A pick up with 4.0L and running with gasoline in europe? can you imagine that?.

I think it is a problem of culture. They don't have culture of saving energy. This is the right place for wasting energy, wasting water and wasting everything included food. And why is it? Because they are plenty of money dude!.

I have a Firebird, it is 3.0L and runs with gasoline, as every muscle car does (yeah, I'm wasting too ). I think these guys want to feel power beneath the accelerator pedal, and they think that fuel engines can develop more power than diesel ones. What they don't realize is that a turbocharged diesel engine can develop a lot of power and can be very dynamic at low regimes. And taking into account the huge number of traffic lights they have here, it would not be a bad idea to have a TD engine for helping in the accelerations.

I cannot believe that I just saw the terms '3.0L' and 'muscle car' in the same sentance!
Whatever you started smoking after you moved to the States, I want some.
When I mentioned my engine size to some Brit soldiers (they have a training camp near here), they needed a translation before they could envision it. As soon as I explained that it was 7.3L, the first response was "You'd be ostrasized in England."

Hey man, don't laugh at my Firebird. A 3.0 L with the weight it has makes it to be a ****ing flying bullet. Maybe your truck of 7.3 is so damn slow as a turtle compared with my car.

That is also true. The americans use the car even for going to shop at the market in the corner of the same street. The curbs here are empty. Nobody walks. Everybody rides. It is crazy!. The malls are in the middle of nowhere, the distances are huge!. So everybody has, in the worst case, one car. There are even races for parking as near as possible of the mall door. The highways have at least 6 lanes, and some so-called streets have 4 in the same direction. But the number of cars is becoming huge!.

 

[chroot]

I'm not trying to totally derail this thread, but you're right Clausius2, America is madness.

I personally know people who are seriously considering paying $100,000 for the next generation of lithium-ion powered electric cars... and who, at the same time think I'm crazy because I ride a bike an "incredible" 15 miles.

Whenever I see people talking about hybrids and diesels -- which are only on the order or 10% or 20% more efficient than conventional gasoline-powered vehicles -- it makes me cringe. I say we'd all be better off if you kept your gas guzzler, bought a bicycle, and just drove the gas guzzler half as often.

Possibly, but I can chirp all 4 of those 33" tires going into 2nd gear (with a damned automatic tranny... which has to go). More importantly, I can climb over you to claim your parking spot.
The Roadrunner, on the other hand, is 446 ci (7.14L), pushing 650hp with low 12 second 1/4 mile times. The new motor that I designed for it will be on the order of 2,000hp. That should alter the times a tad.

If all the americans would use the same engine than you, then if I were iranian I would start to be afraid...

Pray to God for not having a new increase on gas price, if so your 7.14L and 2000hp will be sleeping in your garage for a long long while. BTW do you already have a bike?.

 

[ShawnD]

As soon as I explained that it was 7.3L, the first response was "You'd be ostrasized in England."

Try not to associate size with power. For example, my parents owned some 5L GM vehicles from the 1980s, but they only had 150HP. Yes that's right, 150HP, to run a 4000lb car. Slowest vehicles ever, and the gas mileage sucked. You would be absolutely thrilled if for once you managed to get 15mpg in the city. Cars seemed ghetto before they had computer controlled fuel injection. That's silly that it requires 5L of engine displacement just to make 150HP. My little Honda Civic, through the magic of computers, can generate 140HP with only 1.8L displacement.Back to the topic at hand; we don't have diesels in Canada because they're impossible to start when it's -40C outside. For gasoline engines, gas companies make "winter gas" which has more light ends in it such as butane to help get the engine started when it's really cold. A cold diesel engine requires something heating the engine. I suppose you could have something run off the battery, but that would drain your batteries.
Europe doesn't really get this problem because most parts of Europe are relatively close to the ocean, and there are no mountains blocking the warm air from the ocean. North America has mountains on the west side called the Rocky Mountains and mountains in the east called the Appalachian Mountains. Areas between these mountain regions do not receive warm air from the oceans, so the temperatures drop much lower than in the areas located between mountains and the ocean. Just as an example, winter in British Columbia will never be as cold as winter in Alberta or Saskatchewan.

On a similar note, Canadians drive to the supermarket because nobody in the world can carry 200lbs of food at a time; that's about 8 thick plastic bags full of food, much of it containing water which is damn heavy. The alternative would be to buy food every single day, so you only need to carry 30lbs per day, but you spend about 2 hours per day (8% of your life?) just buying groceries. That's unrealistic at best.

 

[chroot]

My current car has 240 hp from a 2.0L engine, strapped into a 2,700 lb. chassis. It gets about 28-30 mpg on the highway. I still try not to drive it much.

There's no substitute for cubic inches.
The thing that I don't like about buzz-bombs is that you have to rev the **** out of them to get that power. As a for-instance, my Camino at idle in low range 50/50 split will push a revved-up Honda backwards in a head-to-head contest. And the gas mileage in high range 70/30 split on the highway is better than my 305 Camaro with cruising gears got.

You sure got the winter Diesel scene right. The place that I used to work at took over the local U-Haul outlet, and there was nothing that we could do to get those damned things started. (And while I'm at it, I would never in my life drive a U-Haul. There wasn't one of them came through our place that had decent brakes, steering, or electrical system. Our orders from headquarters were to put them back on the street ASAP. We refused a couple of times and demanded a mechanic to visit, because someone would have died trying to use the truck. HQ was very displeased.)

 

[denni89627]

The major reason is that our diesel fuel is not nearly as refined and clean as the diesel fuels available in europe. Most of those cars would not run too well over here. So the question becomes "Why isn't our diesel fuel better?" Smells like big oil politics to me.

 

[denni89627]

Also diesels run pretty good in the cold, its' the damn fuel again. It "gels" at a certain temp and then you're screwed. You're supposed to mix a special additive into the fuel when you expect really cold weather. For the record my old poland spring truck was like clockwork. 10 deg F it would run fine, 9 degrees, no way.

 

[Danger]

Well, sure... wish we could have a nice balmy 10 degree F. winter day in Alberta. We'd go for a picnic in the park.

A normal winter day in Edmonton is about -13F (-25C). A "cold" Edmonton day is maybe -40F (-40C). Drive a few hours north to the booming oil town of Fort McMurray and a cold day -76F (-60C). Alberta winters aren't even that bad; Manitoba has horribly cold weather by comparison.

Danger, not all modern cars need to be reved really high to get that power. For example, a Nissan Sentra has the same engine size and torque as my Civic, about 129 ft-lbs, but it's at 2400rpm whereas my Civic is at 4000rpm. As expected, my Honda gets way better gas mileage, but the Sentra could crush my car in a race.

If you've got a saturday to kill, go test drive a Sentra. I think you would be really impressed.

 

[Danger]

I don't think so, but I'll give you the benefit of the doubt and maybe try it out... when I can afford to get my license. I can't renew it until a couple of outstanding fines are paid off.
By the same token, I think that you'll change your mind if you can find a nice 440 Challenger, 429 Torino, 455 GTO, or similar.
Oh yeah... leave us not forget the 403 Javelin. They weren't too popular back in the day, but they go like stink.

 

[ShawnD]

Don't worry I won't need to find one of those older muscle cars. When I get a bit older looking and more 'serious business', I'll go down to a Dodge dealer and test drive a new Charger. The SRT8 model has a 6.1L V8 with 425HP and 420ft-lb torque. It's a beautiful car too.

 

[Danger]

Yeah. It's nice to see the factories getting back into the real spirit of things. Personally, since W is agitating for a new vehicle, I'm pushing for the Hemi Magnum.

 

[turbo]

Here is my buddy's car launching off the line. You see, Steve keeps his oil pan real clean and he likes to show it off. And yes, is is a 340 Duster with a stock displacement motor.

[Danger]

Sweet.
There is one little thing about that, though. When the suspension is optimized, the entire car will lift almost uniformly rather than squatting and hoisting the nose. A 'wheelie' actually detracts from acceleration. That doesn't make it any less impressive.

I may be wrong about this, but I think in a high-horsepower application like this, wheelies are a desirable thing, because they transfer the weight of the vehicle to the rear wheels (minimizing tire slip) and the slight retardation in initial acceleration (like winding up a spring) allows the driver to dump the clutch just a bit early without red-lighting. Without the weight transfer, the rear tires would likely slip, resulting in a loss of power, and less consistent ETs. The trick in bracket racing (Steve is in Super Pro) is not raw speed, anyway - it's consistently hitting your dial-in (ET) without going under.

 

[Danger]

Never thought about the 'red-light' aspect. Interesting idea. I'm not sure about this particular class either, but in general your initial spring wind-up and throtte control should be enough to maintain traction. In fact, the height of the pinion snubbers makes a significant difference to acceleratilon through the stoppage of that wind-up. The other aspect is the adverse effect of the 'angle of attack' of the body from an aerodynamic standpoint. You're pushing a lot more air out of the way with the underside than you would with the top. If the wheelie isn't sustained for any appreciable time, though, that won't make too much difference.

 

[turbo]

I hung out with Steve off and on during the development of his drag car, and often accompanied him to the track, since we worked together. I can tell you that by the time he had the engine putting out lots of power, modified his transmission, and beefed up the rear end, he was smoking the slicks pretty bad and that was hurting his consistency. His next step was to go to the big low-pressure slicks (with screws through rims and into the beads of the tires to keep the rims from spinning in the tires). That's when he started pulling these wheelies, and his ETs got really consistent. He had to go to 90/10 shocks on the front end (they extend easy, and resist compression on the way back down) to keep from smashing the deep-sump oil pan when the front end comes down. If he wants something done to his car that requires precision machining or specialty equipment, he farms that out, but anything he can do himself, he does, and he is a perfectionist.

About air resistance, there isn't much velocity off the line - just rapid acceleration, and by the time air resistance could become an issue, the front end is down. The wheelies don't really last that long. It is impressive to see that car leap out of the box as the front end starts to come back down.

Honda S2000?

I drive my 4Runner all the time, just because I love it (on and off-road). 330Hp and 4100 lbs equates to about 16 city and 21 hwy though

Still, it's a CHOICE. I could have bought a Honda Civic if I wanted (and I still may, in addition to what I have now that is), but I view my SUV as a functional toy more than anything. I go off-roading, I camp, I don't have to worry about the roads being plowed

I would have bought a Hummer H1 with a Turbo-Diesel , but they're so darn expensive, plus maintinence can be viscious when you break something. It would be awesome to have a HUGE SUV like that and run it off of home-made Bio-Diesel. Maybe someday...

It's interesting to see, it seems like the "new" muscle car movement is occurring in diesel trucks... Smokin' tires, big torque, man it's fun! My friend has a Dodge Ram 2500 with a 24V Cummins, it puts down over 1000ft-lbs of torque! It only gets 17mpg, but it ALSO gets 17mpg towing a 10,000lb trailer.

The gel isn't really an issue except while going through the filter. Many diesels have heated filter housings so once the thing is warmed up it is a non-issue. If you burn what is known as #1 diesel which is much thinner or a mixture of #1 and #2 cold weather for diesels isn't an issue. Some of the early diesels were started on gasoline and switched over to diesel when running. Where I live it is not at all uncommon for diesels to start at 20 to 30 below zero F without warming the block first.

 

[ShawnD]

That's pretty damn good. How does it have so much torque? Is that just because it's a diesel?

 

[cactus429]

As every ignorant American once said.

I have a Firebird, it is 3.0L and runs with gasoline, as every muscle car does .

Pontiac NEVER produced a Firebird with a 3.0L. The only engines that come close are a 102hp 2.8L and a 140hp 3.1L. And if equipped with either of those engines, the car weighs 3,300lbs. <---- NOT LIGHT.

That's silly that it requires 5L of engine displacement just to make 150HP. My little Honda Civic, through the magic of computers, can generate 140HP with only 1.8L displacement.

Apples to apples, my friend. Not apples to watermelons. That 150hp V8 also probably had a compression ratio in the neighborhood of 8:1 and has 2 valves per cylinder. Your honda is upwards of 11:1 with 4 valves per cylinder. It's not the computer that determines an engine's HP. It's advancements in quality of fuel in the past 30 years. Higher octanes allowing the widespread use of higher compression engines. Your civic also has NO TORQUE... Look at your torque specs... embarrassing. The first V8's in the 1900's had 30-60hp and 1 barrel carbs. Ferrari makes 500hp from 4.0L... THAT'S the beauty of compression and technology.

The major reason is that our diesel fuel is not nearly as refined and clean as the diesel fuels available in europe. Most of those cars would not run too well over here. So the question becomes "Why isn't our diesel fuel better?" Smells like big oil politics to me.

Diesel fuel in the UK is about 1 pound per liter... That's 3.7 pounds per gallon. 3.7 pounds in USD is about $7.40. We pay $2.50-3.50/gallon for our diesel. It's better fuel, and they pay a lot more for it too.

Back to the topic at hand; we don't have diesels in Canada because they're impossible to start when it's -40C outside. A cold diesel engine requires something heating the engine.

Any modern diesel vehicle (direct injection) with a healthy motor and good glow plugs will fire at any temperature with proper fuel treatment... just like a gasoline engine.

My current car has 240 hp from a 2.0L engine, strapped into a 2,700 lb. chassis. It gets about 28-30 mpg on the highway. I still try not to drive it much.

Show me one NON TURBO production car that has a 2.0L engine and 240hp. The honda S2000 makes 240hp from a 2.2L engine. Not a 2.0L engine. That power also comes in at a staggering 7,800rpm. Take one look at the torque on the s2000 and try not to wet yourself.

- Power: 240 HP @ 7,800 rpm; 162 ft lb @ 6,500 rpm

HP is a myth. Japanese cars above all should be rated in torque so we can see how weak they are. By the way, try driving your s2000 to 7,800 rpm all the time and let's see how long your engine lasts.

Here is my buddy's car launching off the line. You see, Steve keeps his oil pan real clean and he likes to show it off. And yes, is is a 340 Duster with a stock displacement motor.

http://www.dragracecentral.com/drcphoto.asp?ID=122866

Very cool car. Stock displacement, but not stock compression. I'll bet you 100 bucks he's running 13:1 compression or higher. I'll also bet he's got over 50 grand into that car too. Anybody can take any car... polish it, caress it, love it, spend 50g on it and turn it into something fast. The wheelie really is not that impressive to me. I can take a 1986 ford ranger, drop a 5.0L engine from a Lincoln into it with a manual transmission and pop wheelies. A wheelie is nothing more than a visual spectacle of not being able to put power down correctly. There's a reason the big boys use 4wd (Lambo and other supercars of the like)

My friend has a Dodge Ram 2500 with a 24V Cummins, it puts down over 1000ft-lbs of torque! It only gets 17mpg, but it ALSO gets 17mpg towing a 10,000lb trailer.

Interesting... I have the same truck. A 2005 24V. To make 1,000 ft lbs out of the Cummins requires a immensely fat wallet... to do it right anyway. My truck makes 800ft lbs, and I get nowhere near 17mpg. In fact, if I drive it "spiritedly" I'll get 9mpg. I only get above 15mpg while NOT towing and babying the pedal ALL the time (not something I'm prepared to do when I have 800ft lbs under the pedal). While towing a 10,000 lb trailer, I'd be surprised if you got any more than 10mpg. Your buddy has been feeding you a little dose of BULL**** it sounds like.
