Each unit of these locos has a Kharkov 10-cylinder (opposed) two-stroke 10D100 engine that produces 2206kw (2920bhp) at 850rpm. Cabbed units weigh 138t (the uncabbed slightly less) producing 86000lbs of tractive effort. They have no silencers, hence the volume and the nickname 'Rolling Earthquakes'. The Kharkov two-stroke engine is said to be a copy of the Fairbanks-Morse units in US. Although unsuccessful in the US, they seem to have worked well in Russia and most of it's surrounding countries.
Making those engines work aren't they. If I had to guess, either the engines are not very well maintained, or are being worked at the upper end of their ability for prolonged periods.
I'll say that they have a problem when making the mix (Air and diesel) and they are adding more diesel than Air, but yeah what you said, that Happens because of the Lack of maintenance (basically Look how dirty are the Wagons, that reveals an absolute Lack of maintenance)
Well, consider each car about 65 tons (oil tanks and freezers) and do not forget the track is quite sloped and with sharp curves - there two beasts must work on full throttle to pull this train up the hill. It is the same in the States, there usually are three to six locos operating interstate cargo trains as well.
Видео ОТЛИЧНОЕ!!! ПОБОЛЬШЕ БЫ ТАКИХ!!! ТЕПЛОВОЗ МОЩЬ,ОНИ ДЛЯ ТОГО И СОЗДАНЫ ТЯГАТЬ СВЕРХТЯЖЕЛЫЕ ГРУЗЫ НА ДАЛЬНИЯ РАССТОЯНИЯ ТАМ, ГДЕ ДРУГИМ ЭТО НЕ ПОД СИЛУ И НЕТ ВОЗМОЖНОСТИ!!!
This smoke is probably not all due to poor injector maintenance. In tunnels oxygen gets depleted quickly and this results in partial burning of fuel. Hence the smoke. This problem was encountered in the USA, too. The response in the age of steam was the cab-forward locomotive type, which at least allowed the crew to get the first and best of the air. Then came the "tunnel-motor" diesels, which picked up the more oxygenated air at rail level instead of the hot air at the top of the tunnel. Russia sucks, Houston Railfan? Take a look at some old Southern Pacific photographs.
John Hine Your explanation is wrong though. It takes a hell of a lot of oxygen deficiency to partially burn fuel - indeed, modern engines recirculate a large amount of exhaust gas into the air intake to reduce emissions. It also doesn't explain the fact that they are still smoking like a bitch when it is drawing all the clean air in the world after it has left the tunnel. So yeah, your explanation is incorrect. The smoke is from a variety of reasons. It's an opposing piston 2 stroke engine, so it'll be burning more oil than a 4 stroke, power is being applied to accelerate the train, but the engine revs are still fairly low so the turbos aren't forcing enough air in to the cylinder to efficiently burn the fuel without producing soot, and the injection timing could be a bit retarded (by design), which would explain the flames you see out of some examples. All in all, it's not the best or most efficient of engines.
Maybe you can read my reply to "Pingas the Fourth", in which I mention turbo lag. Yes, sure, the engineer wants more power, gives more fuel into the engine and it takes the exhaust-driven turbocharger a little while to catch up. Add the tunnel factor, which must be significant since Southern Pacific went to a lot of trouble to deal with it. Then there is the possibility of sloppy injectors. Finally, maybe a 2-stroke, as you say, is always going to produce more smoke than a 4-stroke. So I agree with your "variety of reasons". By the way, a lot of Russian locos are now being re-engined by GE, so these more modern power units will produce less smoke. *****
Try looking at other videos of the same model locomotive. There are probably some good examples clearly displayed on the right side of the (full view) page. They do throw a lot of smoke, even with no tunnels involved. And it _may_ not be because of poor maintenance (although that likely contributes), but due to the fact that these locos are probably decades old, based on even older designs, they _were not designed_ to minimize pollution (which is not an easy task)...because Russia just doesn't f--king care about it the way we in the Western world do.
1984 i visit sibiria in my hollidays, Novosibirsk, Abakan /Sajan Schuschenskoje, Irkutzk, Bratzk, with airplane. I do not see this Diselloko. The hydroelectric power station (Sajan Schuschenskoje) was to make with Elektrolokos. excuse my bad english
@florinlifticariu . Unfortunately nope. Old tunnels build in the soviet times didn't have any air conditioning. Passing such tunnels is a hard job indeed. Train engineers just close the windows in the cab, however there's plenty of smoke in the cab. Thus they try to pass such tunnels on a high speed. But even this doesn't help because most of the diesel-powered trains are actually freight trains which move slowly. Moreover some of the tunnels are longer than 1 km. So it's a hard job.
Definetly a diesel, each section of the loco pumps out something around 3000 hp (these videos made me do some searching on the web). By the way, steam loco would make a 'choo-choo' sound I think :)
What a formidable consist! I wonder what could be done to clean up the exhaust gases: Not so good from an enthusiasts viewpoint but the engineering challenge is there!
no, those long cars carried soviet strategic rocket forces ICBMs. that's right, nuclear weapons-tipped intercontinental ballistic missiles. one per car. the top of the car was hinged on one side, and it would open up. the missile launcher inside the car would raise the "business end" (top) of the missile for vertical launch. the windowed crew cars were for the crews and armed soldiers who protected, maintained, operated and (potentially) fired the missiles. more coming....
OK, Pingas, I get what you are saying. I was just talking about tunnels. Of course, you will see diesels smoking in locations where there is no tunnel. A cloud of smoke during initial acceleration is probably due to turbo lag - i.e. the motor gets extra fuel which is not burnt fully until the turbocharger gets up to its proper speed. Then the extra oxygen catches up with the increased fuel supply. In that case the smoke should disappear quickly. However, if smoke persists for a considerable time / distance then probably the explanation is just defective injectors.
The first cars of train were freezers accompanied by machineroomcars. (That cars with windows and doors which are used for operating the freezers) Than there were platform car with three 20 feet containers, a gondola car and the rest were oil tankers.
hell yeah! finest russian power around 18000 horses storming that hill with some really heavy load, considering the russian fuel quality.. i think were near to crude in this case ;)), seems those locos are very healty. and stop arguing about the pollution, sure, for the moment it look hard, but i think hauling that freight on trucks and roads would be much harder for enviroment..enjoy that beautiful train :) keep those trains in service, please :D greetings the shrimp
My bet is that those locos are extremly used. Just look the color of the smoke. It's gray, not black. If a diesel engine is making grey smoke, means that, there is not enough pressure in the cyllinder to make the diesel oil to ignite itself.
2 takt dieselmotoren roken altijd zoveel bij volle belasting. In de usa was deze dieselmotor in vrachtwagens zeer populair maar naar ik meen inmiddels verboden. In Europa alleen viertakt deze roken veel minder.
Fairbanks Morse 2 stroke opposed piston diesels always smoked. check out company called achates which has reworked this style of engine. amazing stuff that will change engines in the future.
The climate collapse is caused by greenhouse gasses, and what you see in this video is not greenhouse gasses. The smoke you see is unburnt fuel (coal, soot). It looks nasty but will fall to the ground since it is heavy particles. Yes, it will pollute the ground around the railroad but not the climate. Hope you feel better now. Railroads are better than any other mode of transport anyhow!
They definitely got engineer in them too with radiotransmiotter, so they can communicate with the head engines. Only thing I wonder- how the hell the engineers ever sit in those, not getting suffocated with so much deisel exhaust!?
Former Soviet/Russian missile train. Carried ICBMs, roofs unhinged for firing. Missile crews rode in cars with windows. Trains were disguised as "refrigerator cars". You can find proof of this on Google.
@KapteinOpel Russian Diesel locomotives from Former USSR are old, rusted, damaged and unstable. It smoke so hard that operators need gas masks, also pollute environment
I wonder, they all seem to smoke like this, if u notice every loco on the train does; I suppose they could all be worn out, but I suspect that the russians just set the fuelling like that to get the power figures they wanted, just a guess. These r 2 stroke opposed piston engines.
Un treno composto in gran parte di carri frigorifero e cisterne, su rampa in curva di forte pendenza...le macchine devono lavorare al massimo per salire...ovvio che fumano come vaporiere.
