Did you all know that the most powerful diesel engine used for land hauling is a v style engine used in locomotives. So much for that inline theory. imp: I see yalls jaws dropping rotfl
Since i know its going to get posted anyway........ THE most powerful diesel in the world: 5,608,312 ft/lbs of torque So much for your V theory :stir: :stir: :stir:
haha ya seriously inline motors rock! so im gonna have to call those guys and have them build me something for my truck :stir:
It's a generator engine, doesn't have to work hard so thats probably why a V engine works in that application. oke: Trains are giant hybrids.
New to the site but this inline is better im not really buying it. It depends on the application. The Navy uses 2 3618 V18 333Lt Kitty to propel the HSV-2. So it does depend on the application. http://www.chinfo.navy.mil/navpalib/factfile/ships/ship-hsv.html
locomotives use electricity to power the wheels true. and the diesel engines are running a generator and SCR ,thefore, the diesels work even harder because there is engergy loss from mechanical to electrical back to mechanical. Diesels turning the elecric motors prodce a crapload more torque that is required to get those loads moving, and that my friend is the undisputable truth opcorn:
yeah inline motor do rock, but v style motors rock just as hard, well maybe just a little harder better get to calling the guys rotfl
Um....the reason why locamotives are hybrids is because it is MORE efficient to use electric motors than hooking a big fat engine to the wheels. In theory, the electricity that is produced through a much smaller engine and generator contains more energy than a gallon of diesel in a giant engine trying to move the train.
Actually, that's not quite correct. Diesel to Electric is used because of the low rpm torque characteristics of electricity. Basically, an electric engine puts out N ft/lbs of torque even at 0 rpms, which is used to get the train moving from a stop without slipping the wheels. To use diesel mechanical would require HUGE gear reduction, many speed transmissions and would still go through clutches. Or a hydro coupler which would generate lots of waste heat and other problem. Electric drive just comes out much easier, cheaper, and more efficient in that application than any direct IC mechanical drive.
Yes, but the title says "Most powerful diesel engine period......." All i was doing was stirring the pot, nothing more.
Hey Joez, i didnt mean anything negative by it. btw, can you imagine how big the hood of a pickup would have to be to fit that engine
I think this thing is stupid because this has no real point... if they wanted to build there v moter in an inline version it would have just as much power maby more
Exactly. A perfect example of this is haul trucks used in large scale open pit mining. Virtually all of the big trucks (240-400 ton models) are diesel electric with Cat being the exception, although that is changing soon. Diesel/electric drive is just a more efficient way of doing things when you get to a scale that large.
Low Bid! They could have used the 3608 (in line 8 cyclinder engines) at 3500hp, two per shaft. The last ship I did regulatory oversite on was the Nathaniel Palmer, an Ice Breaking capable Artic Research Vessel. The builder and the charterer wanted reliability of the InLine engine and the capability of doing maintenance on the engines without loosing time on missions. The Charterer was the National Science Foundation. The ship has been in service now since the early 90's. http://www.researchvessels.org/country/USA/Palmer/ Don't see how this has to do with Brand Wars? So getting back to that subject, the little 5.9 cummins may soon get an overhaul putting out 6.7 with 325hp and 850ftlbs of juice. (Bigger Crank and deeper pan?) To be seen, we hear, in the the Dodge 4500 and 5500 Trucks which currently are still serving time in Mexico. Next year they say. Dave
Most powerful diesel First of all locomotives are usually 3,4,5, maybe 6 tied together, Am I right? they are also diesel electric which means the diesel hp is being converted to electric torque. And as I said before. You want to talk land hauling, look at the K Dubb's, Petes and freightliners with a STRAIT 6!
As a rule of thumb, railroads use a 1 to 1 ratio. 1 HP per 1000 trailing tons. So if your train is 15,000 tons you would need 15,000 HP. Most locomotives have around 4000 HP each, so you would need 4 in this application. This is why you see a mutiple engine consist.
For the normal person. The locomotives use induction elec. motor. These have a neat characteristic of producing infinite torque at 0 rpms but that torque drop off exponentially as it starts to turn. This makes them perfect for starting loads that weight a few million pounds
