@KPAracing Not quite. If I remember correctly, the lab that was filming this (if this is the same one) had a bearing failure (which is what you hear up until the connecting rod finally let go) and you see the end result. The engine "picking up" was from internal resistance catastrophically building up as time passed. Most of these things control at a speed/torque relationship, so however their control was set up, would generally increase throttle to compensate for the lost load output.

[@BigLisaFan]

The parts flying out of this engine were of the finest quality.

[@invicta1313]

Actually, I think this was probably a development mule, which is why they were filming it. I would imagine that the entire point of the test was to frag the engine to see what broke.

[@psychopitt1982]

Richard Rowe yea I believe so as well. Almost like they dropped a over loaded amount of torque on the motor to see what would fail first And how

[@stollifa]

Would be nice to have a look inside this engine, to see what is left there. Looks like a burned piston caused a connection rod to break, then vavles break and finally something got stuck with with the crankshaft throwing it entirely out of the engine. This is a massive malfunction and showes what forces rage inside a machine like that. Awsome!

[@mustie1]

I can fix it

Yes

Where most small engines would've swelled the crank bearings and seized up. A big diesel is like a horse! It'll quite literally run itself to death.

[@wayouttherewi]

Great video! Rarely do you get to see the bottom end coming apart like that, since the engines are usually installed...

[@BeastandBird]

Could be an oil pressure indicator.

[@nos4me]

Probably loading the engine up

[@quillmaurer6563]

Come to think of it, probably part of the dynamometer load system, as the engine loads up, starts to bog down, at that moment. Seems like it was revved up no load prior to that, then this engaged the load and boost ramped up.

I love the flat line sound after it blows up lol

When parts and pieces start falling out of the engine let up on the throttle.

[@uwus74]

Very good question...! I am not sure about the answer but consider: This is not a failure - it´s a test. In the full video you seee a firefighter entering the test cell directly after it chrashes. A possible answer: Engine is runnig at a high load poin, than at sec.: 24 a valve (you see it next to the air filter) shuts the complete exhaust. Even though the pressure after the turbo rises, but the turbine wheel still produces enough pressure to get fresh air into the cylinder and enable combust

Hey, a sweet girlfriend did that while we were dating in H.S. to my company-supplied pickup truck as we were going about 25mph down the street. Stalled the engine, scared me (thinking "I'm dead") and worse. 50 years later we still keep in touch!

[@kolsen6330]

My favorite was the girlfriend telling me that the oil light came on when she left work. Can you look at it? After driving at 70 for the 40 miles or so home.

[@dylanmurre123456789]

its called a run away. diesels dont need spark. just compression. so once oil starts gettin passed the rings the engine just keeps goin till it blows up, or you stop the air flow by stuffing something in the intake.

[@PhrostyPhoenix]

All very much like my first marriage. Nice n smooth, purring along then Bam! Cough! Puking oil and other juices everywhere in a plume of smoke. Dub in some cussing and it would be pretty close.

[@Ajswindowshelper]

yes if you watch very closely around 0:31 you can watch the rod fly out of the oil pan (the rods control the valves which let the air and fuel mixture into the piston and the exhaust out ).

@BeeEmmW Yeah true man, that makes sense!! Either way, I still think this was an intentional failure to see how the block might stand up... I dont know :/

[@FonZ4590]

This is a case of overrevving when the enginebrake failed and it revved up to its breaking point, Imagine you driving 180 mph in 5th gear and then put it in 1st gear and then without the engine brake protecting your engine, it will rev craaaaazy high

[@eatmuscleshitimport]

that must be one hell of a truck to go 180 mph in 5th gear

[@jaroslavuradnik7552]

when you put it from 5th to 1st gear your enine explode.

[@SpencerHHO]

No it won't you'll get compression lockup and the wheels will essentially lock up and you will crash, this will still probably blow your engine up but you have absolutely no idea what you're talking about.

[@sivalley]

@danwat1234 What you saw was the brake arm being pressed against the tail-shaft. This is a destructive load test. What you see happen is the crankshaft twisting itself in two before breaking the oil pan to bits. Based on what I can see in the video, that engine was putting out at least 700bhp at close to 9k RPM based on the pitch of the engine.

[@robhuiting1041]

This engine is a perfect example of humanity.... driving itself to the END

[@T_Eighteen]

yes but the pressure will keep building up because the pressure going into the cylinder is actually far grater than pressure going out. yes the burnt gases will escape through the intake but it will just re-enter again with the fuel with it.

[@TheSuckerOfTheWorld]

Wow that diesel sounded as if it was turning 5,000 plus rpms. Insane for a diesel.

[@JustinSolaGratia]

Kinda wish I could see the RPMs as well as the pressure of a few things while watching this..

[@Arthafer]

Very nice ! I nearly finished my engineer Bachelor and i can say that somehow one Piston or one bearing of the engine doesnt get lubricated enough, and u can hear the engine ream at 0:25 an after some time the bearings get to hot and it explodes :) But olso could be something other, but this happens most of the time

[@ThePaulv12]

Spoken like a true engineer with no field experience.

[@LaTerata]

In your first post you said INTO the PISTON, and in your second you said cylinder. Number 2 is correct. And I never got on you about the valves because you were right on. Your first engine sounds like the one in the video :-)

[@mikeshotrodshop]

It looks like a MAN TGX V8 engine. (it is a diesel). They are made in Germany. Seems to have had a dyno-failure which released the load and underwent an over speed.

[@dougslittlediesel]

I love it as it shuttered to stop. Priceless !!!

[@marijanabrezic8854]

+dougslittlediesel i don't know why it gave a rough shaking after the engine block was filled with holes and emptied from oil

[@fedealosgolpes]

I think is been properly explained already but yes is very likely been the case that a conn-rod bering seized (first squeaking) and may be they meant to continue the test or may be they were not looking?, weird but once the bearing seized to the crank shaft what happens is the rod cut of, and then the crankshaft keeps on turning of course with the part of the rod welded to that journal and brakes the block around loosing oil but also unbalancing the crankshaft very fast and surely #2

[@shizzle5150]

I heard of 2 stroke Detroits running away like this. Apparently even cutting the fuel is not enough to shut them down as they will start pulling oil from the crank case and burn that too. Only way to shut down a runaway Detroit is a co2 fire extinguisher to the intake. At least that's what I was told by a guy that seemed to be a pretty knowledgeable mechanic.

[@jcglessner]

@ youngdones anything can be fixed... looked to me like something cut loose in the top end and caused at least two rods to blow out of the oil pan. I'd be really surprised if the crank isn't junk too. So short answer is yes, but I'd say it's time to start with a new motor

[@cirian75]

me too, they must had heard it failing, You can hear the bearing failure start at 18s

[@sivalley]

@danwat1234 Destructive metalurgy testing, they wanted to simulate worst case scenario for determining mode of failure of the weakest component, in this case the crankshaft could not hold back the immense downforce put on it by the traveling piston near the back end of the engine. The closest real world analogy would be going from 100mph to 0 in 3 seconds or less without disengaging the driveline while at full throttle.

[@SRT480]

i can agree with that, unfortuneately none of my vehicles had small blocks

[@asshatnowhere159]

yes it seems it is a v8, I think someone else said that it was a marine engine, if so then i would expect it to be quite big. i would guess way over 5-6 liters.

[@smpstech]

@DSLCUMMINS MTU 8V 396. It's a marine diesel.

[@JordonVW]

it'll be fine! could probably do with a new air filter though, bits if metal and oil are on the old one, after that it should be good as new ;-)

[@dburns8381]

I LOVE watching these $20k to $40k engines grenade.

[@argh1989]

Yes, it's a test but we don't know if the engines destruction was part of the plan. I don't think it was supposed to happen but surely they have to consider things like that to happen. And as I said in another comment intake pressure is limited by a bypass valve, wastegate or blow off valves, it cannot increase endlessly.

[@Bakjeknapper]

Awesome, broken connecting rods banging the molten pistons, crackshaft keeps spinning till end... what a pain.. Thanks.

[@i_dodge_trees]

@JohnxWaynexGacy it's a diesel, it ran away it sounds like meaning it ran off it's own oil somehow due to a failed ring, headgasket. anyway motor oil gets into the combustion chamber and because it's a compression fired engine, well you can't just turn off compression...

[@pgani]

A shine to the cylinders and as good as new.

[@geeknproud321]

Small blocks are insanely easy and cheap to work on.

[@ditchjumpa]

I think that lever that moves is the torque arm of the dyno head. Could be wrong though. Highly doubt it's the 'governor'.

[@flecur08]

look over the back of the engine. There is a lever or some shit that goes down when the engine starts to make noise. Might be a bubble in a float gauge. Possibly oil pressure?

[@kalanike]

@Lnx805 That was a Mercedes-Benz OM441LA V6 Diesel Engine

[@howsey182]

Its the timing, its all over the place........ So is the cam, valves, con rods, pistons, followers and the rockers! Apart from that it flew threw its MOT!!

[@fedealosgolpes]

#2 in this case causing other rod braking making more bit and pieces blow around, not a veri nice thing to do with an engine though, I guess it was a test of braking point? extrem load ? but it could happen in normal duty if oil pump fails or bad assembling or a very cold engine reved up to quickly

[@pipoveyron]

@vidmanproductions where were you ten years ago. honda engines now is considered to be the most reliable.

[@theLonewhitewolf13]

Really you guys are talking an engine retarder caused this fail. #5 or #6 main bearing was installed incorrectly. I do not know what the valve near the air cleaner does as it falls right at 24 seconds as the sound of the engine changes. Could be oil pressure I don't know. This engine was freshly rebuilt and thrown on a dyno and the engine was warming up before you put full load to test torque and hp. Very first part of the engine to go was the crank at #5 piston on the right side of the block. And with engine retarders like jake brakes they can put out no more then the max brake horse power than max horse power. If it was a an engine retarder failure it would be near the head and or gear train. At the top of the head or front gear train.

[@deathgrind1]

Hahaha they shrug off the fatal engine jerking and "ride that sucker out" for a full 6 or 7 seconds after! Nice driving bro!

[@marcb8934]

Can’t wait to see an engine on here at maximum boosted revs and it survives 90,000 bhp and screams so loud it shatters glass due to the sound level and the dyno blows up a top rpm

[@jogrobler]

@BeeEmmW What I think happened here was that they were stress testing the engine by inducing abnormal forces on the crankshaft. I'm really no expert, but the sound that follows, and the noticeable movement of the engine makes me think they applied stress to the crankshaft, therefore overworking the engine causing it to blow. Could be wrong though??

[@peppersdog1]

i worked in engine testing years ago i was standing next to a cosworth engine at full power 7000 rpm when the cardon shaft to the brake let go...it hit every wall in the test cell but i was lucky,dangerous job

[@jtho53]

[@fredcruegger9734]

never use a four stroke in racing or high energy applications. as well as the engine oil needs to be replaced with gear oil, which would lower the wear.

[@Tugboatpb]

Love the cinder blocks

[@CarterKoontz0906]

Its a Detroit. You can tell by the color of the block. Mercedes is silver/grey

[@invicta1313]

@BlueAlchemist Could have been the piston rings, especially if this is footage from an oil test where they ran the engine until the oil failed and it blew up. Honestly, that's what I suspect; it coulda been running for a week before it blew as far as we know. Interesting you'd say that about the crank -- that shrieking right before it blew sounded to me like a crank grinding against the block with no bearings between them. No bearings + seizing pistons = crankshaft go bye bye.

[@dodge69874]

Jeus, that was horrible. Is that oil pouring out the bottom at the end? By the size of the exhaust, I think it might be a diesel engine.

[@MrByootox]

Well.. thats why these engines are tested in the room, better there than in a vehicle

[@SRT480]

i guess it comes to experience. the mine i worked at use Komatsu 1000hp engines to power their haul trucks and they never went wrong. same with the German engines they had in a few of the smaller 100 ton trucks. on the other end the Detroits with double super chargers where always down, but to be fair they where twice as old. but power wise detroit decimates all

[@chrismcadooak47]

may need a new set of mains and rod bearings

If you see in the back it looks like they shut some kind of exhaust valve to create massive back pressure. Looks like it was some kind of test..you can hear the noise as you see that valve move down.

What was the problem? Sounds like the lubrication stopped and the piston abrades...

from what I know this was actually a really old Chevy engine. either way, I'm not gonna point any fingers at any company, this is most likely an assembly error by a third party and not the company that made the engine.
