New US Heavy Vehicle Emission Requirements

[AWD Chaser]

http://www.autoblog.com/2011/08/09/f...nnounced-will/

If you're not sure why today's announcement from the Obama Administration about the first-ever fuel economy standards for heavy-duty trucks and buses is important, read this.

Okay, now that we're all on the same page, let's take a look at the new standards. These aren't specific MPG targets like passenger vehicles have. Instead, different vehicle categories have different improvement targets. The headline numbers from the EPA are that the new standards will save $50 billion in fuel costs and around 530 million barrels of oil over the life of new trucks built between 2014 and 2018.

To put that in perspective, the U.S. uses around 19 million barrels of oil a day, so we'll be saving just under a month's worth of the entire country's appetite for oil from heavy-duty trucks built during these four years.

As for the standards themselves, semi trucks are required to achieve a 20-percent reduction in fuel consumption and greenhouse gasses by 2018, heavy-duty pickup trucks and vans a 15-percent reduction, and vocational vehicles (buses, garbage trucks, etc.) a 10-percent reduction. The improvements will come from mostly off-the-shelf technologies, and a second phase dealing with trucks built after 2018 will require the use of more advanced tech and save even more fuel.

Similar to the passenger car and light truck standards that were proposed the other day, initial response to the heavy-duty truck standards has been universally popular. This shouldn't be a surprise, since the administration worked with "truck and engine manufacturers, fleet owners, the State of California, environmental groups and other stakeholders" to develop the standards. The Heavy Duty Fuel Efficiency Leadership Group, for example, endorsed the rules

Will this ever come here and how would it affect us?

Volvo is up to Euro 5 as is Scania ( I think)..... Seppo Trucks have always been about 15yrs behind in technology.

And we don't call them Trucks if they weigh less than 4 tonne either

[Lukeyson]

american trucks are just crazy as, probaby about time they try to make some standards.
Love the big F trucks, Tanner Foust in a F450 doing circle work, and pulling some train and carriage on this weeks Top Gear USA was comical

We have a little IZUZU at work and it has some fancy thing where it re-burns all the trapped soot (?)... from the engine. Reading how if the light comes on made me laugh, as you have to pull over for 15mins and not park on dry grass!! as it burns hotter to kill off the nasties...
Hmm yes i can see delivery drivers waiting patiently for 15mins on the side of the road....

Cant remember what its called, only briefly read the handbook.

DPF - Diesel particulate filter

http://en.wikipedia.org/wiki/Diesel_particulate_filter

A diesel particulate filter, sometimes called a DPF, is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Wall-flow diesel particulate filters usually remove 85% or more of the soot, and can at times (heavily loaded condition) attain soot removal efficiencies of close to 100%. A diesel-powered vehicle equipped with a functioning filter will emit no visible smoke from its exhaust pipe.

That be it!!! lol

Yes when the filter clogs you have to stop the truck and wait 15mins as it burns off the soot.

I believe that the CFA/RFS are having trouble with these Isuzus, when they go into the burn off mode they can start grass fires if they are in long grass or scrub.

Good thing that there's a bunch of Fireman around then

Ha yes the drivers manual warns NOT to park over dry grass when its burning off the soot, however this shouldnt really happen a lot unless it idles all day?

[aussie muscle]

they had a garbage truck on the show on discovery science where they cut up stuff to show how it works. All garbage trucks in san francisco city all run the particulate filters (and it can crush a car in it's skip!)

Unofficial Details Leak out About Next-Gen Ford and GM Pickup Powertrains

Horsepower matters but mileage is the mandate.

by Paul A. Eisenstein on Jul.29, 2011

Ford's F-150 EcoBoost engine shows there's a lot of room to improve fuel economy without sacrificing performance and payload.

The pickup market, though barely half the size of its one-time peak, is still a viable – and profitable – force in the U.S. automotive market. So, expect to see Detroit makers, in particular, do everything they can to retain the segment’s viability – though that won’t be easy, especially in light of today’s announcement outlining tough new mileage standards set to reach more than 50 miles per gallon by 2025.

Next-generation full-size pickup trucks from Ford and General Motors will have to balance towing and hauling capability with unprecedented frugality to meet the tough new Corporate Average Fuel Economy standards.

Your High-Mileage News Source!

That has some folks worrying it may be too much of a challenge to pull off, at least not without sacrificing the functionality American truck buyers expect. But don’t plan on holding onto your big rig ad infinitum. As we’ve begun seeing with such innovations as the turbo-powered EcoBoost V6 on the 2011 Ford F-150, there are some promising ways to reach mileage never seen before.

Here’s the latest information from our insider sources about the engines that will help Ford and GM, in particular, accomplish this feat.

Ford is said to be working on two all-new six-cylinder engines under a program codenamed “Nano.”

The Nano mills are expected to continue Ford’s efforts to shrink engine displacement while using turbocharging to boost power levels and return superior mileage. They are said to have displacements of approximately 2.6 or 2.7 liters and 3.0 liters and are expected to find their way into the next-gen Mustang as well as the F-150. Other Ford vehicles are likely to host these engines, as well.

The 3.0-liter V-6 is said to have a power target of approximately 300 to 315 horsepower, almost the same as today’s entry-level naturally aspirated 305-hp, 3.7-liter V-6. Instead of twin turbos, the Nano engines are expected to use so-called dual-stage turbocharging, where two different-sized turbos work independently or in tandem. One turbo is used at low speeds for drivability and fuel economy, while the second turbo spools up at high speeds to deliver extra power.

GM is expected to offer four significantly updated or new gasoline engines for the 2014 Chevrolet Silverado and GMC Sierra, in addition to the workhorse 6.6-liter Duramax diesel V-8. All of the new gas engines will feature direct injection.

Heavy-duty trucks are said to receive an exclusive 6.2-liter V-8. Currently, a 6.2-liter V-8 is only available for the 2007-12 Silverado and Sierra 1500 half-tons. Light- and heavy-duty models would share a 6.0-liter V-8 that’s currently only available for 2007-2012 Silverado and Sierra HD pickups. In early planning for both large displacement V-8s, supercharging was considered as an option (similar to the 2009 Chevrolet Silverado ZR2 concept truck) for maximum power while maintaining fuel efficiency. However, supercharging has been dropped from consideration for now.

GM’s next-gen half-tons are also expected to continue offering a V-8 with 5.3 liters of displacement and a turbocharged six-cylinder engine that can compete head-to-head with Ford’s 3.5-liter EcoBoost V-6. Six-speed transmissions are expected to be the standard gearbox for all engines.

Don’t think Ford and GM are alone in racing to find high-mileage solutions. We expect to see some intriguing technology emerge from Chrysler’s Ram brand, possibly taking advantage of some technology derived by its European partner Fiat.

As for the imports? Toyota’s Bob Carter confirms to TheDetroitBureau.com that, “We’re in the truck business to stay,” with a next-generation Tundra absolutely in the cards. And considering Toyota’s focus on fuel economy that could mean some interesting solutions.

(For more on Toyota’s future full-size truck plans, Click Here.)

Nissan’s product czar Larry Dominique advises that a next-gen Titan is also in development. Powertrain? To be determined. Dominique notes that “We’ve been able to achieve a lot better mileage than anyone thought possible just a decade ago,” thanks to such breakthroughs as direct injection, twin-turbocharging, six, seven and eight-speed gearboxes and other once unforeseen technology.

He admits he’s nervous about finding what it will take to reach the 2025 truck target of 54.5 mpg, as are Nissan’s competitors, but it’s clear that with so much riding on the results the changes we’ve outlined here will likely be just the beginning.

Pickup =! Truck

However, fuel efficiency goals for Heavy Trucks can only be a good thing.

In Australia, we are at Euro5 for Emissions, Europe goes to Euro6 very soon...

We have no efficiency mandates, nor does Europe, from memory.

Hate to be a nerdy nit picker, but we are at ADR80/03. To Comply with this a vehicle can be compliant with Euro-5 or US EPA-07 (there is an equivalent Japanese standard which escapes me.)

There is no real difference between these emission levels, but the idea of getting the yanks to adhere to Euro standard and vice versa is way to hard.

ADR80/04 - Euro6 - US EPA-10 are all mandated for heavy vehicles here in 2014.

Passenger cars just went to Euro4 last year.

As for efficiency, your average Semi uses fuel at the of a quarter of a Prius per tonne moved.

Stop stealing my job! Hahah.

About time...the manufacturers over there got away for far too long making unneccisarily massive trucks that masqueraded as "passenger cars" and didn't have to meet any passenger safety, fuel economy, or emissions controls, wasting oil and getting 10mpg at best. They were massive status symbols, nothing more. If you've ever seen a H2 Hummer up close, get inside and have a look...it's not without good reason some magazines laughingly called them "a reverse of Dr Whos' Tardis"...in other words, much less space on the inside than the outside size would suggest should be in there...

If Australia and Japan can produce quite large vehicles that still get reasonably good economy, then it's about time the Yanks realised a world exists outside thier shores and came into line with the rest of us...

[GASWAGON]

Anyone realise the benefits of Ecoboost tech and even our new EcoLPi yet????
Non believers need to re think and take a look at what's happening NOW around the world...it will be hard but it has to be done ...by law....
Besides the U.S use way way way too much oil as they have for decades!
