I will never understand how you can add exhaust gases back into the combustion Chambers and get a more efficient combustion burn oxygen is what supports combustion ,burned,used up exhaust gases will tend to stop the clean oxygen rich fuel cycle,from acheiving a more complete burn of the fuel!,Wouldn't a more oxygen rich environment promote a more effiecent burn useing up the fuel and thereby not creating as much pollutants! I've noticed that on several new cat and Cummins engines that fuel milage is way down from engines made say as of 1994 my new peterbuilt truck only gets about 3to4 mpg on a 503 cid engine rated at 330 HP. My old truck had an 855 cid engine rated at 350 HP and got 9 mpg and much more torque ,.So how can I burn two times as much fuel and get better cleaner exhaust???? Please somebody explain this to me???
The objective is to reduce pollutants. In perfect conditions an engine (or any combustion of petrol, diesel and the like) should only result in water and carbon dioxide, which is a greenhouse gas but not a pollutant. In practice, combustion is messy and a lot of other stuff comes out: soot, particulate, nitrogen oxides... Forcing part of the exhaust to go back will break down these pollutants and achieve a more ideal combustion. Burning spent fuel absorbs energy, thus decreasing efficiency and increasing fuel consumption. The amount of oxygen will always be more than enough in a diesel engine. In a petrol engine, you can control a variable geometry turbine via software to ensure an oxygen rich combustion
MTU builds wonderful engines. Too bad they have to choke them with EGR and DPF's. That DPF housing looks like it takes up about 1/3 the space that the engine takes up, and requires the burning of more fuel to regenerate. Older engines without the alphabet soup of emissions systems are more efficient.
An excellent video;explicit,clear and well thought through!Thank you to MTU-whoever or whatever that might be!
Great technology and efficiency, the future looks bright for the internal combustion engine.
Great video! It is good to know that our beloved diesel has a future in the emissions-controlled world.
5 BAR?! That's impressive!
I like bars!
I helped on this project
it's a good engine
i am going to my next job MTU... engine i am very exited to work this engine and this video is great
Twin Stage turbocharged, intercooled, and DOHC 4v heads. From someone in the car world: cool!
+Josh Moss Looks more like single cam in block pushrod four valve, which is even cooler.
Josh Moss not any over head camshaft
nice video easy understanding
great pool of knowledge
Very good video
good video and explanation
Good video, and good engine. :)
Good job !
Good
Motoren Turbinen Union is situated in Friedrichshafen Lake Konstanz Germany in case of anyone wanting to get a Job there.
Great!

good vidio
Que buen vídeo
So these things have two separate turbos? Interesting
my fevrerate railways
perfect
EGR ruined diesel engine outputs and make maintenance costs go out the roof.
Diesel Engine EGR?
Wow!
5 bar??? wow....
Don`t think you can find a better Diesel engine! German engineering once again!
Rudolf would be so proud what his engine has become
Would fit in my Honda?

It's a big issue with locomotive engines since they can't use Adblue unlike on-road engines or marine engines.
The difference of Diesel.
thats it
This is what VW needs to start selling diesel again.. lol
