Good insight and description of the inside of a turbocharged Diesel engine.
I wonder what it costs to do an EGR delete on that thing
Just change the camshaft and it will work
Modification
About tree fitty
That is so good bat the time is short
Gon' put one of these things in me car
Boosted Doge hope it would fit in my honda ye
ah, got a Honda too
Will it fit on a dodge?
You'd have better luck putting your car in the engine!
Might as well just be driving an engine
Wait, you make train engines too?
Locomotive builders buy the MTU engines as prime movers.
Rolls-Royce build a lot of things. Luxury cars, jet engines, the whole 9 yards.
@@AishiMTA They don't make cars. They just licensed their brand name and logos to BMW.
@Valoro85 Rolls Royce have made locomotive engines for years even before they bought MTU, firstly producing rugid and reliable engines like the C6, C8, and DV8 from the late 40s onwards following development of diesel engines during WW2, for use in industrial locomotives, and then buying the locomotive company Sentinel in the late 50s
Great video. Thanks.
Wow this is completely understand for understanding A engine all together.
Similar to GE Tier 4 Locomotive prime mover engines
pretty sweet little animation.
I Hope This engine will fit on my Mountainbike
is that large part at the end the train version of describing a Catalytic converter?
Best video ever thankyou for this video
Cadillac's MASSIVE V16!!
Like the MTU logo with a little bit of Network Southeast style in it.
A twin-turbo train? Pretty cool! Does it make that "PSSSHHHT" wastegate noise? 😂
No
High combustion temperatures increase NOx emmisions. The introduction of exhaust gas that is depleted of oxygen reduces combustion temperatures and hence NOx emissions. Exhaust gas recirculation is inefficient and increases complexity, reduces reliability but reduces NOx also. The exhaust gas is at a higher pressure than inlet air, because the exhaust valves opens slightly early so the exhaust gas "jets" out of the cylinder. This is known as "blow down". As inlet pressures increase, recirculation of exhaust gas presents a challenge, and EGR turbos are being considered. Perhaps hybrid gas turbine/flywheel/ battery combinations will replace the medium speed engine in future, but it's years are numbered in locomotive use. In a few years we will be hovering around in personal solar powered drones made in china, and trains will hover on magnetic field cushions powered by wind turbines. Out little children will have 3 way catalytic converters inserted up thier arse holes at birth, to cleanse thier farts. Despite increasing human population, The robots will make everything and no one will work, leading to boredom, depression, drug addiction and massive increases in gun crime. As the gulf between rich and poor widens, civil war will rage. Any advances made in cleaning the exhaust gases of diesel engines will be offset by all the toxic gun smoke.
*Slowly stands and claps*
That is too much of pessimism. But the AH insert is a brilliant idea.
Then Judge Dredd will appear and say "i knew u were gonna say that"
could not have said it better....
Are they twin turbocharged on the 20V’s
High speed engine 👏👏👏👏
cool
Can you please explain how it is advantageous to introduce burnt gases back into the piston? My understanding is that the inflow needs to flow into a slight vacuum and if you are using spent gases are you not encountering above ambient pressures?
Not so, about inlet manifold absolute pressure being below atmospheric. Narration said it was boosted up to 5 bar (~72 psig) by turbocharger. Vid showed the exhaust gases entering manifold at that elevated pressure. So forget any vacuum there. And gases do NOT enter piston, rather- chamber.
Fred Hollands no vacuum at all except possibly when the engine is starting. The air entering the cylinders is at high pressure under normal operating conditions. Exhuast is reintroduced in small amounts to control the peak combustion temperature. Exhaust is inert and by mixing an inert gas into the cylinder the inert gas absorbs some of the heat lowering the peak combustion temperature. This is done purely to reduce the formation of nitrogen oxides which causes smog. It has little benefit to the engine, reducing efficiency, power output and negatively affecting reliability as the recirculated gas often clogs diesel engines.
The use of gas from exhaust to limit the heat in the cylinder? Why? Is that not a backward step in the tecknicale knowledge?
Read previous comment. Exhaust gas recirc is used in many engines to lower PEAK COMBUSTION TEMP, to reduce output of oxides of nitrogen, and thus acid rain. Not a "backwards step" at all, if you think about it.
Yes it certainly is! They deliberately contaminant the charge air with exhaust to reduce the amount of oxygen in the cylinder and to lower the combustion temperature, car engines now achieve similar results with Miller cycle variable compression cylinders, by altering the closing time of the inlet valves effective compression pressure can be controlled.
Super 🔥🔥🔥🔥🔥❤️❤️❤️❤️
Now gut that huge muffler and reroute the exhaust recirculation pipes up and out. Might as well throw on a nice chrome tip to. Now you have a nice engine.
Some high schooler with a shit box Honda is gonna try and figure out how to put one of the turbo chargers in his car
Does it fit in my Civic ?
Rolls-Royce owns MTU?
Is that a spark plug inside the cylinder???
If yes, how can it be used in a diesel engine??
good question
It’s not. That’s an injector.
No, that's a fuel nozzle.
R/R is the only mark of e x c e l l e n c e !
Smh. Now trains are going to be breaking down as much as semi trucks do. ☹
Hahaha
rr or mtu?
So, here's my question
.
.
.
.
.
.
Will this fit in my Honda?
bro? Yes... Just remove the sits and it'll probaly fit
Nah
@phxxr650r
Are you?
Imagine doing the injectors on that
Could i swap this into my miata
That clutch has to be like invincible because rotational mass and it's a train the clutch would theoretically be deleted instantly
Diesel-electric engines don't have clutches. Read up on them.
So I noticed that you have used a 4 stroke engine in this video and your Industry standard for the 4000 series is a 2 stroke engine. Also the video is misleading. The 4000 series has an EGR valve that sends exhaust gas into the combustion air charge by introducing it BEFORE the cooler and not after it like in the video. This causes severe soot build up on the cooler that is a fin and tube cooler as fine as a radiator. Once that happens, the air charge is reduced and you end up with high exhaust temps in a very short time requiring entire cooler breakdown and cleaning at least every 6 months...
You said it. ERG and DPF are one giant scam.
wow MTU
👍👍👍👍👍
hold on, matey is saying that they don't have particulate filters as of 2017!
What the hell, he talks about it and specifically says they will have these technologies in the future
Boggles the mind
A properly tuned diesel does not need a particulate filter, a slightly lean mixture helps with that. Particulate filters just make you burn more fuel, to burn off the products of burning too much fuel for a given power output.... Ugh.

wow V-16 a motor...
that is lot and heavy weight
Whait, why does this looks so similar to the mtu video. Is mtu owned by rolls Royce
Yes
Don't know what RR had to do with that?? Looked like MTUs own work...
David Hutton Rolls-Royce has fully owned MTU since 2014. Besides that, I don't think MTU has their own TH-cam channel.
My brain 🧠 Hurts 🤯
Why?
Vanessa Del Rio could pull a Freight Train!
I love you guys but the animation is a bit off!! Peak cylinder pressure should be achieved 15-20 after TDC🤣😘🏴☠️
Dear rolls Can we get the Merlin back The Lancaster MkV that flies over my house needs a baby spitfire to escort her
Stupid Brits, still living in the past ...lol
And the reason why you type in English
I could also type in German and French !
But then no one would reply........
And your point is ????
Please explain the sounds heard on this video. The music has nothing to do with subject matter! It's OBNOXIOUS !! WTF?
Good Tutt 80's porn
“In future engines”. It’s a bit bloody late now !
What has this video about MTU got to do with Rolls Royce?
fins59 it's Rolls Royce's now
Thanks for the info, if the video mentioned it I missed it.
Its a part of rolls royce
What, no AdBlue? You can't clean a diesel exhaust no matter how many times you reburn it. The soot just turns to cinders and the fineness of the particulates increases. All good carcinogenic stuff, RR is chasing phantoms.
so nice
Maybe good for tractor pulling... Metered tractor pulling.... .M.T.U.
This is a German technology and engineering ,MTU is German .. This has nothing to do with Rolls Royce..
barracuda7018 It's British now and has everything to do with RR as a full owner of the brand.
Believe it's called business and such.
these engines are german MTU designs but Rolls Royce acquired MTU and owns their portfolio now.
80386 Correct.
To be exact , in August 2011 , Tognum (former MTU-Owner) was acquired by Daimler and RollsRoyce. They hold 96% of the shares. Till 2006 MTU was 100% Daimler .(Sold to Tognum at that date , 2006)
MTU is the former Maybach Motoren Werke. As you know , the modern Maybach cars were build by Mercedes.
Stefan Richter interesting facts no doubts. I would say, working in this line, that this is pretty common. Car business aside which for the larger luxury brands is just a side business, this is a common development.
Today in the marine line if you like to stay competitive you must be able to offer a large range of products.
I’m thinking about Caterpillar got MaK. Caterpillar being a high speed engine most acquired MaK being a medium speed engine. High speed for generators and medium speed for propulsion although exceptions can be found.
Wartsilla get Woodward’s I believe and other smaller companies to stay competitive .
Rolls Royce having medium speed engines, thrusters, design, propulsion etc get MTU which offer high speed engines to their range.
Aren’t most trains electric now ?
edgar pierre nope
This is 2 stroke
It's a diesel why is it showing a spark plug igniting?
Zergling diesel engines have much higher compression ratios than petrol engines ,therefore combustion occurs spontaneosly.
It’s not a spark plug. It’s an injector.
Thomas Strickland I guess the animation didn't do it much Justus
Peter Laustra combustion doesn’t occur spontaneously in a diesel. Diesel is a lot more stable than gasoline. Diesel has to be hot and compressed to ignite. Whereas gasoline is more volatile and could explode at anytime. Please do a little more research.
Zergling the whole animation wasn’t produced very well. So there was no justice to be had. Lol! However for a guy like me that knows everything there is to know about Diesel engines. I’ve got your back.
Exhaust gas going back into the engine will clog valves & lower efficiency & performance ultimately polluting the environment.
It’s about time manufacturers stand up to government & protect its customers & the environment
Not quite as quiet of a phantom
Did an adult review this video prior to release?
You're running 15 psi? Bruh...I'm running 75psi.
@Dante lol. What about trains in nyc?
What's this gotta do with RR? Fell asleep watching it.
It’s not turbin, ITS TURBINE!!! SAY IT FUCKING RIGHT!!!
Switzerland doesn't need these. Their railway network is 100% electrified and all passenger trains are electric
Yea. Clean. Right. Clean my ass.
Better we develop better green power generators with those efficient engines of yours. Leave the automotives to run on electricity as they are less polluting and much easily maintainable. Maybe you should now focus on that next. Hope to see railways fully running on solar energy pretty soon, at least in tropical and sub-tropical zones.
what about the fuel economy ?? :-)
Trains have been hybrid electric for more than 50 years. The engine is only used to run a generator. Trains are driven by electric motors. Diesel is and always will be more fuel efficient. Diesels are the most efficient as they make more torque and it takes less engine RPM’s to get the job done whereas as gas engine works twice as hard.
0:12 "There's no way around diesel engines." Ever heard of an electric train?
Its all about reducing pollution, where does the electricity come from?
My point was that there are alternatives to diesel engines, not that diesel engines pollute.
Electric still has a long way to go, trains not so much since the overhead lines are there giving constant power, I also rarely see electric freight trains? or none at all in the UK, USA. I don't know if the massive weight is a limiting factor to the electric motor.
Peter Smyth the diesel trains are electric/diesel Its like a hybrid
Matt JT there are electric freight trains in the U.K., and there are also massive electric freight trains in Australia, the reason why electric freight isn't as common is because of the costs of building overhead wires and maintaining them, as freight trains sometimes have to cover massive distances, you can only have electric freight trains if the length of the line that the train will have to go is electrified, there's also electric freight in Germany, America also has electric locomotives, whether they use them for freight or not I'm not too sure
Wtf is 5 bar?
cccp3 ...so...5bar =70psi. Thanks. Irks me when manuals only list bar, I have to use conversion calculator.
Planes cars motorcycles and trains
I think it is ship engine 🤔
The title litterally says train engine dumbass
They do put these in ferries, just without the EGR.
I wonder , what if railways hire Dodge to make their Diesel engines 😂
I can see a train stopping to do a parked regen. 😝😝😝
Not clear, far too flowery, needs a simpler more straightfoward explanation - surprised RR put their name on this .....!
Any plans to make a battery-driven long range locomotive that is actually clean?
With all the research and development going into this diesel engine it could have gone a long way towards developing a long-term solution that is truly clean and economical
Mark Small do a little research. They have been hybrid for more than 50 years. Technology is just getting better. The engine is only used to power an electric generator to produce energy for the electric motors that drive it. Most trains can go several hundred miles on less fuel than it takes to fill your SUV.
Battery-powered locomotives are just a colossally stupid idea.
Pantographs are a much better solution for longer routes, with Diesel being best for shunting and local hauling. But maybe most importantly, pantographs actually EXIST, and they DO SOMETHING, while the unicorn technology batteries that would be needed for a battery-powered locomotive simply DON'T exist.
Clean engines?
löl
TOM PIPPS FOAM- BATON ROUGE LOUISIANA USA HI HELLO &
How a train engine work? Pretty much the same way as any other diesel engine 🤨
Great CG... terrible VO.
This is also great but nothing is compared to the BNSF engine
This is awful timing between explanation and animation, not to mention that so much info is skipped, good luck if you want to take something from this video...
Stefan Supra yeah, I got lost halfway through.
fuck emissions, give me more power.
Brag as much as they want trying to make this sound somehow modern and high tech, but at the end of the day, it's just a fucking internal combustion engine... Plain obsolete shit.
100% of trains are powered by electric motors. Diesel engines are only used to produce the electricity. They are more fuel efficient than the truck you drive. I can assure you of that.
That’s not what you were saying. Where are these overhead power lines that you speak of? They sure as heck aren’t here in America. I would hate seeing that crap all over the place anyway. Train technology is coming, I would suspect the maglev systems will be the ones that win. Safer a lot faster, and no ugly power lines. The boxer engine is one of the least efficient engines. However they sound cool and they are very reliable. At least the old ones anyway.
That1TechDude they will eventually however it’s going to take a while. You have to think about what it’s going to take to change a whole infrastructure like that. The last time the train infrastructure was messed with is when Vanderbilt and others created the train system. Other than modernization of it nothing has been done. The fed is going to have to come up with a lot of money to get this done. So when this goes down I guess you could say. It better be a damn good plan.
The internal combustion engine is in no way "obsolete shit", in fact there are plenty of applications in which they will always remain the most practical way to provide power. You're committing an _appeal to novelty_ fallacy here.
