Congress adopts fuel economy standards for heavy trucks
http://www.etrucker.com/apps/news/article.asp?id=65347
It will be a few years before this takes effect. However I see a problem. For example, if we're allowed to carry 90,000 lbs within the future, our fuel mileage will go down, but our ton-mile per gallon used will go up. Our trucks will actually be more efficient. What's needed is BSFC standards. BSFC is how much fuel it takes to make one horsepower for one hour. This is very standard stuff, and the lower number(less fuel) is better. Since horsepower requirements vary so much, this is the way to go. I'd have no problem with congress adopting BSFC specific CAFE standards. I do have a problem with them adopting across the board MPG standards. It just plain doesn't make sense. Should peterbilt be punished for their 389? |

Same truck almost.
I think the free market should decide if one wants to drive an aero truck or not. But that's just my opinion. I think whatever truck they choose, the engine should be more efficient then current engines. |
I would like to see greater fuel efficient engines. They are really needed. I would still prefer to have the market dictate more fuel efficient engines rather than a government mandate.
|
I agree GMAN, unfortunately there isn't any of that. Well we have seen some, for example CAT losing a huge share of the market to cummins.
The problem is nobody puts out cold hard #'s. If they did, I could tell you without a doubt which engine is more efficient. I think the government should mandate that, forcing the OEM engine makers to put out BSFC numbers. They should also have a "minimum efficiency" and slowly work it up over the years. |
It would be much better of all engine manufacturers used the same benchmarks to report their performance. The government mandates less pollutants from engines which reduces efficiency and now wants to raise mpg. I think they need to concentrate on one thing at a time. With higher fuel prices I think it would be more in the national interest to increase fuel efficiency rather than reducing pollutants. Carriers and owner operators would clamor to any reliable engine that would enhance fuel efficiency as long as performance wasn't impacted. The main problem is increased government interference in the form of greater regulations which increase our operating costs.

GMAN, you and I are in full agreement.
Standardized testing of all heavy truck engines, stand-alone, no truck. This will eliminate variables. "engine dyno" if you will. Detroits new engine is interesting, with the turbocompounding and elimination of the variable geometry turbo. |
We may see a thinning of the pack in the next few years. Market share is bound to change. Paccar, Navastar and Mercedes all have engines they will market in the next several years. Navastar and Mercedes are already in the market. Paccar should be in the fray shortly. This could further erode market share for the three major engine manufacturers. I would expect some form of standardized testing and analysis to come into play with all of these new competitors. In fact, a standardized method of analysis would need to be established to make sure all manufacturers were in compliance.
|
It's actually called BSFC. It's a measure of efficiency.
It's the amount of fuel in lbs, to make one horsepower for one hour. From there, you can calculate "thermal efficiency" if you want. Since we know the amount of BTU's in a gallon of fuel, and we know how much horsepower the engine is making. BTU's and horsepower are directly related. |
point bounce?
how did this double post? |
According to the EPA aerodynamics will produce the biggest gains in fuel economy (peter-whatever :arrow: ).
They acknowledge that engine efficiency would be the most expensive way to proceed as they are already (cost return per improvement/investment) as efficent as research permits. Aerodynamics, they claim, (I agree 100%) is the most cost-effective way to go and they're even helping trucking companies aquire the neccessary aerodynamic improvements with government loans for companies that can't garner the cash for such improvements. I'll look for the information and links to back-up the above. I store so much information that I end up not finding it when I need it. Because of national security I think the SUPER HOGS should be eliminated or at least penalized (like smokers, super cig taxes) ther're as efficient/effective as unions. Who in their right mind would CONTINUE hauling products in fuel hogs? The consumer ends up paying for this inefficient fuel hogs via higher prices (as with unions). Let's show the world 'our smarts!' |

http://www1.eere.energy.gov/vehicles...ngs/index.html A lot of good articles in 2006. Also read up on HCCI, variable compression, different turbo designs, etc.. Improvements in engine efficiency can be done, but it has to be done from a "top down" approach. I cannot improve the efficiency of my engine, but I can improve aerodynamics. There needs to be more pressure on engine builders. Economy of scale would also improve. Quote:

Five to 20 years down the road the manufactures will keep obtaining better results. BUT right here right now aerodynamics will produce the FASTEST solution at the LEAST cost. Argue with the EPA, these are not MY findings. IF the efficiencies between engins is so great why doesn't it show in the fuel mileage? Because if it showed in fuel milage truckers would flock to that particular engine. Quote:
The gov. once was trying to pressure GM into designing safer cars. How did GM respond? They SAID *WE* are the gov. so we'll do whatever WE WANT. Didn't you read "Unsafe at any speed?" Quote:

Frankley I wouldn't care if the most aero truck on the road only got 3MPG. Truckers would just have to charge more and people would have to pay more and companys would have to pay people more but, everthing would still be in ballence. Oh and Mandilon if you hate Pete's so much why do you have that avator? |
This really seems like an area where new government regulations that tell the OEMs what to build are not needed.
Now having standards so you can compare apples to apples with different engines would be a good thing. Perhaps have a series of standard tests with for different hauling scenarios, just as the EPA has city and highway mileage for cars. Drivetrains could be rated for pulling a Van/reefer, tanker, doubles, Flatbed/stepdeck/double drop, etc etc etc. The vast majority of purchasing decisions made in the class 8 market are driven by hard nosed business realities derived from data. The UPSs, Con-Ways and Schneiders want the most value from their drivetrains when they buy equipment. Fuel use is already a HUGE factor in spec'ing and purchasing a new truck. Look at how Freightliner and International are duking it out in the pages of Transport Topics with their mileage claims for the Cascadia and ProStar. This is not like the market for SUVs, Pickups & Cars where many people let their ego and perceived needs dictate their purchasing decision. Something like 90% of 4X4 vehicles will never leave the pavement. |
People seem all too willing for the government to jump in and solve all of their problems. Market forces work if left alone. If one manufacturer could find a way to significantly increase fuel mileage, then the others would either follow or lose market share. I see no reason why we should not have trucks that get 10 or more mpg today. I think the technology is here, it is a matter of will and consumer demand.

Mandilon already said its because its a "flag", depsite being able to go on google and lookup a pic of a flag and using it instead.
What he also doesn't care about is spec'ing a T2000 for heavy haul is a lot harder than a W900 or 379. If we all pulled vans or whatever, aero might be the no brainer. I'm a terrorist because I don't have a fairing on the top of my cab and pull a van 8) However, to someone educated, they'd know it would be busted into a million fiberglass pieces by now with all the neighborhoods I go in :lol: |

Second point on this statement is if you keep giving the government more power, they'll eventually come after something you enjoy. It's easy to say to tax or ban something you don't enjoy, but one day it might be something you like, then what? Less government, not more. |
Muslims have been have been fighting over there forever. Christian wars, etc... Oil is their leverage right now. I agree, if no oil, they'd find somthing else.
Still, besides political reasons, fuel efficiency would be beter for the environment and the polar ice caps 8) |

I understand what GMAN and others are saying regarding the market dictating the changes rather than the government, but I have to side with added regulations. I'm sure like the HOS rules the "how" will be argued to infinity.
Our industry is very competitive, and has very small profit margins. Even if an "improved" truck were made available I doubt the impact it would have. Fleets will be replaced as is cost effective, and not before then. The new benefits will be phased in over a period of time (example...07 engines). APU's have been around for years, and have always offered a profitable alternative to idling with the main difference being the rate of return. The only reason they are being adopted lately is because of the high price of fuel. I make this point to illustrate that if the government had mandated their use years ago we would already be benefiting from improved fuel efficiency without having to wait for the market to help make this change. BanditsCousin, et al--Depending on when people want to define the beginning of Islam there have only been Muslims for 1,397 years which is hardly forever. By "over there".......do you mean in Michigan? Or maybe you meant throughout the US, Canada, Indonesia, China, Africa, Europe, etc? Timothy McVeigh blew up a building, and Kahane's followers tried to blow up a girl’s school all without the help of oil financing or converting to Islam. And as far as people fighting I dare you to find a nation in modern times to have done so more than the US. |
Quantitative, the US may have done more, but they have been fighting over Israel for a time longer than the birt of this nation. We're infidels to them.

Is this an owner operator thread? I swear I see company drivers in fuel-hogs too? I dunno, seems like "Everything Truck Driver Related".

If you notice the advertising from Central Refrigerated has reflected the change in fuel prices. They used to advertise heavily on the enjoyment of driving straight nose trucks. Now their advertisements show aerodynamic Volvo's, and other more fuel efficient vehicles. The companies are changing as well.
I am currently working in the largest Muslim nation in the world, and it is not "over there." Despite some of the poorest people living in tin shacks subject to flooding, and without running water they are cleaner than many of our fellow drivers who have access to showers at truck stops. The level of bigotry, racism, ignorance, or stupidity shown by a few of our profession reflects poorly upon the rest of us. I look forward to driving again in a month despite this. Sorry, and this will be my last comment on this subject. All future posts will be solely on topic. See you all on the road soon. |
