In contrast to the 2.0 TDI fron VW this engine runns like a petrol engine! It sounds very quiet and the torque does not fall until 4800 rpm! And the best thing is the fuel consuption: 5.8l per 100km
Have this engine in my Laguna GT and have to say it is absolutley fantastic. The torque is just phenominal. I appreciate a lot of the engine has come from Nissan but even so - Very satisfied with my Laguna DCI GT
The Packard V-24 engines that were used in WWII PT boats were also inherently balanced. They were really just two V-12 blocks joined together end to end. An old WWII Navy vet I once knew served on a PT boat that made night attacks on Japanese cargo ships docked in Tokyo Bay near the end of the war. He said his boat would do 50 knots at full throttle with a full load of torpedoes, then run up to 65 knots after their torpedoes were fired and they were hauling ass out of Tokyo Bay.
they use 2 pumps. in located in the fuel deposit. the other one is mounted to engine is generated a pressure between 1800 and 2100 bar. that's a very high pressure, with such pressure it's possible to cut your fingers and anything else. the high pressure pump on a common rail is a piece of art.
the torque comes from the longer stroke necessary to make the high compression possible. The ultra high compression creates alot of heat that ignites the fuel.
@boilingpoint2 Common rails dont use injection pumps, just a supply pump to pressurize the rail. The high pressure atomizes the fuel better for a cleaner burn.
BRILLIANT explanation. I was wondering at that too. At first, I thought this was a vid explaining some of the details unrealistically just so you get the point. I was thinking, "no way the injectors would spray like that per stroke." Is there a power performance drop or gain by using this system?
more valves means the engine can breath better which reduces internal resistance in the engine .. or something. One thing I have thought though it that with more valves, theres more springs to compress which does take energy away from the engine.
high pressured fuel system - before the injectors stable high pressure delivered equaly to all injectores wich provide a much more effective fuel jet/spray... which is more easyly burned and able to disctribut it self move evenly inside the combustion chamber
gilessmokey (1 hour ago) cant tel exaclty too... i supose the "piezo" is related to the highvoltage peaks that run through that coil inside the injector that makes it open and spray the combustion chamber... meaning the high voltage actuates a little mechanical movement, enough to open the injector and allow the fuel to go where it is suposed to go.
why aren't the intake valves actuated from one camshaft and the exhaust valves from the another? you would have a single row for intake and a single row for exhaust valves with that way of valve actuation, and the air would distribute more evenly via the both valves
@barixkhan Whow...just thinking after reading your explanation of a Canadian engineer named Gerald Bull who experimented with a new type of artillery, it was a very long barrel with multiple charges spread throughout the length of the barrel, to propel the shell faster with multiple explosion following the shell's path inside the barrel....
@boilingpoint2 Needs to be compressed with air. The process of compressing a liquid/air mixture heats it to the point of combustion for diesel engines since the
In this engine, the intake/exhaust valves are not on either side of the engine...the intake and ehaust alternates on the length of the engine, IEIEIEIE.
deffo a gain, as your introducing more frequent pushes against the piston, instead of one massive push and then leaving the force and eventual inertia to provide the power. In reality, what you want to achieve is the piston being forced down for its entire stroke, instead of one bag and then motionless travel down. Marine Diesel engines (21kbhp+) are (God Willing) going to be designed with this in mind.
Well, not being into Marine machines, I don't know what the basis of comparison is. Are you saying they're already in excess of 21kbhp, and with this procedure they'll have even MORE power? And thank you so much for your detailed response!! That makes so much sense. Is there any hope of gasoline engines doing the same thing?
grnjiant (1 hour ago) ah!!... there is also a little spark that ingnites from the tip of the injector to the top of the piston, not seen in this vid... to replace the lack of that ultra high compression see the "common rail" video
These modern engines in principal without going into too much detail are full of great ideas...but in reality are over complex. The gains in going down this design road are minimal and the unreliability issues are fiancially crippling on these vehicles' owners. Its time these manufacturers came back down to earth with their designs and may be they will begin selling cars again. The only sensible feature was the syncronous chain and gear.
hi! update your-self "friend"!! MR9 engine as 15.1 comp & example... 1.6 honda engine has 90 mm stroke... and 9.2 compression older diesel engines (20 15 years ago) had arround 32:1 compression then TDi came... drop compression to 20's presently with low anti-friction aditives oils API SM and "strict" emissions they are already 15, with tha added fact of the complicated injection systems besides due to stroke, compression is due to piston and combustion chamber size as in gas engine .
Less balanced? Do your homework. Flat engines are naturally balanced. The only other naturally balanced engines are straight six, V12 and Rotary engines.
i am in a trance, science and art, athough in a few years time when i come to change the glow plugs on one of these engines, they will be covered in shite like all the rest.
oh! yes indeed... also details to consider to those designs. uhm ...so... about the marine engines they take lots of damage with the salt environment... i supose. So, the reliability is restored with a less agressive mechanical design.
ahhaa indeed now i see .. where the fokin torque comes from... that 2 sprays after TDC.. mofos i really dont lyke the the timming chains rubbing plastic though
I was hypnotized enjoying the vid when suddenly the EGR system showed up......damn!!!

This is Brilliant,..ive been trying to explain to my son just how an engine works and with this vid its made easy,...thanks for a great vid.

@boilingpoint2 Common rails dont use injection pumps, just a supply pump to pressurize the rail. The high pressure atomizes the fuel better for a cleaner burn.
Pretty impressive. It gives people that don't really understand what goes on under the bonnet of their car a bit of an idea!

65 knots, Thats some serious power. I always love reading shit like that.
Thanks
It's a Nissan chaindrive and hy- valve adj. in X trail DCI 2007-2012
more valves means the engine can breath better which reduces internal resistance in the engine .. or something. One thing I have thought though it that with more valves, theres more springs to compress which does take energy away from the engine.
fucking awesome the best engine animation ive seen on here to date

This video is amazing, but I can not undestand how the particulate filter exactly works. Are the particulates "burn out" periodically? tnx
why aren't the intake valves actuated from one camshaft and the exhaust valves from the another? you would have a single row for intake and a single row for exhaust valves with that way of valve actuation, and the air would distribute more evenly via the both valves
I wish nissan/infiniti would offer this engine as an option for the cars that now have QR25DE or the VQ37VHR engines.

don't question a producer that's make a wide varaity of engines, including engines that could go over 20.000 rpm used in F1
: )
@HD2512DK Renault and Nissan made a joint venture in 1999.
What software is used to make this? Very nice looking engine. I really like the improvements in diesel tech.
In this engine, the intake/exhaust valves are not on either side of the engine...the intake and ehaust alternates on the length of the engine, IEIEIEIE.
this is a very nice illu
thanks dude
does the variable nozzles on the turbo replace the wastegate?
do you know how much force it would take to 'stretch' the metal in a timing chain ?
amazing demonstration!

i've never seen such a video... great indeed :)
I liked your video.Can you give me control system diagram M9R engine, please?and pinout sensors?I needed for my course project. thank you very much!

What is the name of the song??? Also, where can I see a HD version of this!!!???
Can we have a HIRES version please?

what is new in this motor????
cool watching my new engin in Nissan x Trail:)
Renault Forever !!!
I wish nissan would do this for the 3.5 (now 3.7) VQ35DE
@moptim You should write to Renault and tell them to fix it...
variable swirl is coming soon!!
incredible
nice vid.
it swirls the fuel for more efficient combustion
cummins is also gonna use high pressure rail
Nice, thank you man ;)
very impressive

tks
Great !!!
eventually the built up particles get burned off from the high exhaust temps
good vid
this is nice!
man everything was great but when i saw multiple point injectiong i jizzed!
WOW nice!
if you watch the injection you can see it fires 3 time this is to make the motor quite. very cool cgi
Wow Awesome!!!!!
yes
they should of made this a flat four instead of a in line four.
Muito bom!
This is like porn for a mechanic.
why?
@al3xbV 21 people have prius
google images: high pressure pump audi v6 tdi, you'll see a 3 cyl radial pump
Chain drive and hydraulic valves = Nissan but nice video
WOOOW

@sqhschief Anyone know?
Nic nowego.
10 lat za Niemcami 15 za Japończykami.
Renault działa jak Microsoft 80% środków na reklamę 20% na produkt i stąd takie fajne filmiki ;)
u right..my renault 19's 1.7 liter distribution belt broke...not cheep to fix..i'll scrap the car
i am in a trance, science and art, athough in a few years time when i come to change the glow plugs on one of these engines, they will be covered in shite like all the rest.
Acest motor îl am pe Nissan x-Trail 2012

@naturalyshocked :D just wondering!
diesel the future is here...............
Valla la mierda!!! k tal makinon csm!!! cada vez mejores.. =)
ok giless thanks...
for now, i dont need a-cure-i-see LOL i see only what the basic change is.
Would be better if it was a 2 stroke =D
@ellebal1111 hahah sounds like a plan
fucking EGR!!!
The Germans had a variable hydraulic turbo 50 yrs ago.
ahhaa indeed
now i see .. where the fokin torque comes from... that 2 sprays after TDC.. mofos
i really dont lyke the the timming chains rubbing plastic though
scrap
Muito bom!
