New greenhouse gas restrictions on medium- and heavy-duty trucks are pushing change into the marketplace. The regs offer truck makers more compliance flexibility than the diesel-exhaust rules did, and makers like Ford who take a "choice" approach -- offering customers most of the major choices to satisfy emissions regs -- are spreading alternate-fuel and drive train technologies throughout their lineups. Ford offers everything from compressed natural gas (CNG) and liquefied natural gas (LNG) to hybrids, plug-in hybrids and battery-only electric vehicles. "The Ford full line of trucks (Transit Connect, F-Series and E-Series) all offer some type of an alternative fuel option," says Len Deluca, director, Ford Commercial Trucks. "By the second quarter of next year, all of the trucks will offer the CNG/LPG option." Vocational trucks will need to take a much different approach than over-the-road tractors. "In the vocational world, there are not a lot of things we can do with aerodynamics," says Bob Mann, Navistar. Instead, much of the focus will revolve around certain truck accessories. "Today, a lot of those are basically driven off the engine. We are going to be looking at other ways to [drive them]." Navistar is developing LNG and CNG vehicles, and is among leaders in the move to hybrid technology in utility trucks, where the engine can be turned off and the body operated with stored electrical energy. And Mack Truck says the trucking industry is moving toward smaller engines overall. Mack reports that for the first time, 13-liter engines have become the No. 1 choice of U.S. Class 8 truck customers. "We're seeing a shift in the market to less than 15-liter engines as customers increasingly focus on operational efficiency," says Kevin Flaherty, senior vice president – U.S. and Canada.

wait till you start getting EGR, DPD and SCR comming in.. its killed most of the american engined trucks in Australia
we have a 2007 International 7300 quad dump truck with a cummins ism motor in it. have had to replace the egr valve 5 times already :Banghead, mind you that the truck has only 225k miles on it. we are also on the second turbo, soon to be the third...new emissions = junk. egr delete kit will be put on this winter
Wow, that sounds like a disaster. What do International and Cummins say about it?
international won't do a dam thing about it..cummins did warranty the first 2 egr valves but they stopped there. a mechanic at cummins told us personally to buy the egr delete kit..they will not put it on however lol
What reason did they give you for the parts failures?
We've had our international at the dealer for EGR repairs 5 times in the last year. (All under warranty) The dealer is 135 miles away and this is starting to get old.
Do they have EGR cooler problems or just EGR valves?
The valve
only reason they gave us is that they are junk..literally that is what the owner of the dealership told us. they know it too, but there is nothing they can do about it. "national" international won't let them put the delete kits on, but they are for sale. figure that out!! have heard from that dealership that other guys with the same motor have had the same exact problems..new emissions B.S. = junk!
a few years ago caltrans had a fmc sweeper lng fueled it got passed around to differnt areas was a real dog ,,mostly on hook from tow truck . it couldn't run a full day on a tank of fuel and when it would run out of fuel it was dead in the water .becuase you can,t run out with a 5 gallon can and get it going ,it has to sit over night to slowly refill tanks..but becuse clean air was more important than money every sort of new idea was a good idea to leaders
Agreed, but i would rather deal with the egr problems than have to deal with DPF fluid.
yes i agree with you on that! i have heard that they have already found a way to bypass those on the new pickups, something about just being able to fill them with water? have only heard bits and pieces. don't know anyone that has one. if this is true, it won't be too long that the big trucks will have something figured out to bypass
I have not heard of anyone doing that, wouldn't surprise me though. :{)
cat has ther problems to
I've heard that you can run distilled water in them and it will run fine but the o2 sensor will flag a fault code, if you get caught doing it down here there big fines
