Keith Browning Posted September 17, 2008 Share Posted September 17, 2008 With all that I have been reading in the last year I almost want to work on/for them. It is a new truck that could save nearly one thousand gallons of fuel a year. The new DuraStar Hybrid truck was unveiled this morning at West Michigan International Trucks in Wyoming. It is a diesel-electric hybrid.The DuraStar is manufactured by Navistar International. They say it offers a 30-to-60 percent fuel savings over traditional commercial trucks. Don Alles of the Eaton Corporation says, "This truck has a standard medium-duty chassis that can be used in a variety applications. One of the most exciting is in the utility and municipalities where a bucket truck might be operating at a repair site and operating almost entirely on electric power at that time. The savings there could be substantial." The DuraStar Hybrid is the first truck of it's kind to use this diesel-electric technology Quote Link to comment Share on other sites More sharing options...
SteveS Posted September 18, 2008 Share Posted September 18, 2008 Interesting. So it is a Hybrid like passenger vehicles where there is a battery pack and electric motor that helps propel it down the road AND it can connect to the grid when working stationary? Or just that when stationary it can be connected to the grid and then not need to run the engine for PTO? Quote Link to comment Share on other sites More sharing options...
Mekanik Posted September 19, 2008 Share Posted September 19, 2008 Sounds pretty cool. I wonder which IH engine they are using. Quote Link to comment Share on other sites More sharing options...

Bruce Amacker Posted September 19, 2008 Share Posted September 19, 2008 With all that I have been reading in the last year I almost want to work on/for them. I'm sure you would be very welcome there. IH has a true objective of doing what it takes to make the customer happy. They have FSE's and guys that have the ability very quickly to authorize out-of-warranty repairs for things that went wrong that shouldn't have. They also do not have a one-repair policy for warranty claims like FMC has. Their Uptime Programs are also a true example of how they handle redesigned parts, and they are installed at no cost to the customer. On the VT365 (6.0) this can equate to several thousand dollars of new rockers, sensors, EGR, turbo cleaning, reprogramming, and etc. to cover things that weren't quite right when they left the factory. I have seen them bend over backward numerous times to do the right thing. I tease Anthony regularly about adding CP PSD repairs to the menu at his/our local IH dealer. I feel it would add a half million dollars of annual gross to his benefit, and he thinks he would be lynched by his fellow co-workers. /forums/images/%%GRAEMLIN_URL%%/laugh.gif He does still work there part time along with almost full time with me. While I don't claim to be an expert on hybrid trucks, I believe Freightliner is using the same Eaton hybrid drive system. It's really not that new as we do training for Florida Power and Light, and they've had prototype hybrids several years now. FPL has told us that when they break Eaton sends guys (engineers, probably) to diag and fix them. It says in this link that they have 3 with 5 on order, but I believe that is very old info as I think they have more than a handful in their fleet at this time with the eventual fleet size of 600 hybrids. I've seen them, but was not able to get pictures of the hybrid drive in their fleet. Here's some shots I took at the Louisville Truck Show this year, the trans looks like their medium duty AutoShift with the motor/generator in the forward area: /forums/images/%%GRAEMLIN_URL%%/coffee.gif Quote Link to comment Share on other sites More sharing options...
BustedKnucklez Posted September 30, 2008 Share Posted September 30, 2008 Don't modern locomotives run on diesel-electric power? /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif Quote Link to comment Share on other sites More sharing options...
eastendpowerstroke Posted October 1, 2008 Share Posted October 1, 2008 Don't modern locomotives run on diesel-electric power? /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif "In 1917, GE produced an experimental Diesel-electric locomotive using Lemp's control design, the first known to be built in the United States." WIKIPEDIA Yeah so it's not really "modern Locomotive" technology it's been around for many years why nobody has used it for other modes of transportation I don't know /forums/images/%%GRAEMLIN_URL%%/shrug.gif Quote Link to comment Share on other sites More sharing options...

Those were basically diesel hybrids. Quote Link to comment Share on other sites More sharing options...
Fredsvt Posted October 2, 2008 Share Posted October 2, 2008 The big difference between a d-e loco and a truck hybrid is that the big diesel in the loco runs wheel motors, not through a transmission. And there is no battery pack, it's pretty much direct from the electric generator to the wheels. Then on decel they send the energy produced by the wheel motors when in dynamic braking to a huge resistor grid on the top of the loco and it's dissipated by the huge fans on the roof. Here's a question, why aren't they using either in-wheel motors or something similar in hybrid cars/trucks? Quote Link to comment Share on other sites More sharing options...
