Race Pistons - How are they manufactured?

[3RBRoach]

Anyone else come here looking for Solidworks tutorials and get totally sidetracked for the last hour?

[douchechillum]

Do Germans ever have fun?

[keebordcowboy]

your granny is checking on the piston quality...hehehehe

[dayvedchow]

G-CODES :D

[carlitoselunico1]

isint that the guy from the pink panther?!!

[boucivicsir]

this guy i s so ready for movember!!!

[LongRangeBullet]

OH GOD, HE TOUCHED IT AT THE END. IT'S TAINTED!

[toob247]

i want a job starring at sexy pistons all day :)

[xXxDANMANxXx]

Fucking quality, no brainer though, germans do it til they get it right it's basically in their blood.

[top1street]

germans are the best

[dogytalk]

press 5, he has an orgasm

[bufbarnaby]

I love how the British say...Al-you-minium ; )

[xcessivecc]

This is where they build the Terminators... Don't be fooled, the German guy is one of them.

[4ivIV]

You noticed he mentioned a CMM machine. That stands for co-ordinate measuring machine. In America, the American Society for Non-destructive Testing (ASNT) issues the standards for training. I would guess there is a German equivalent group. It appeared they were doing fluorescent penetrant testing (FPI) testing. I would imagine they do eddy current and ultrasonic testing, too, as these can determine cracks below the surface.

[MANIAC187KILLA]

why does this guy wigle win he talks

[loko95ftp]

that is sick!

[lamestnicknameever]

Only the trained human eye can check finished product?

Did it go through crack testing? Did you mill it? Its finished...

What sort of training do you need? Highschool diploma?

Yeah german dude way more annoying then british voice.

[bommobiel]

wow that german guy... talking about stereotypes!

[rockitman150]

Valve springs on a race engine vir the modal ? maybe it will bounce and brake HeHe.

[akchronic79]

must be one hell of a salary..!

[ajofscott]

You guys can have all of the pistons...all I want are those CNC machines!

[eeretz]

all that washing and drying, to take the pistons with the bare hands with no gloves! LOL... oh premium gas please...

[alexoprel]

ugly face, he could be a cop

[warracer03]

@alexoprel but he's more than 10X times smarter than you are...

[alexoprel]

@warracer03  who said i was smart? if i was smart i wouldnt spend my time on fucking youtube. wise-ass.

[TheJonnypatton]

Did the narrator make anyone else think "Cashier number 6, to your collection point please"?

[SGSUPERMAN105]

The voice over is the same as some of the videos at my school. Kinda funny.

[bobodd5]

dogshit

[JGMagoo]

Quenched with WHAT?????

[kyleisreallycool]

@JGMagoo with horse semen

[captainwre]

FUCK YOU AND THE HORSE YOU RODE IN ON COMMERCIALS!!!!!

[lolbewbz]

Whats your job?

Oh I'm a racing piston inspector.

[mushere2k9]

@lolbewbz its just such a cool sounding job init LOL

[ooSPIYDAoo]

Boring and uneducative video,

no insight into piston manufacture at all... 

just a bit of advertising blurb...

[nigel0o0o]

German technology ftw.

[rustlerboi1052]

OMG calculus like no other @ 0:41

[naturalyshocked]

i wouldn't buy a piston if it wans't made by Mahle.

[ZXLNT]

Alu MI NUM not Al U MI NI UM... 4 syllables

[Chrisco247]

@ZXLNT actually it is spelt aluminium...so it is 5 sylables

[Chrisco247]

@ZXLNT actually it is spelt aluminium...so it is 5 syllables

[cllcn888]

@Chrisco247 both acceptable

[thekkl]

@Chrisco247 Humphrey Davy, the chemist who first isolated Aluminum electrolytically named it Aluminum, not Aluminium. The pronounciation currently accepted in the UK only got started thanks to Aluminum sounding classically different from other metals of the time. Thus Aluminum, the American way of spelling it, is actually correct.

[theundeadx]

@thekkl most people in the WORLD use the word aluminium, who cares how american spell it. both pronounciation accepted by IUPAC (aluminium favoured) and came from britain anyway, nothing to do with america.. and you spell his name wrong there, its Sir Humphry Davy..

[thekkl]

@theundeadx Just because more people do it one way doesn't make that way correct. Also, I never said anything about Humphry Davy coming from the US or Britain because it doesn't matter where he's from because the way he decided it's spelled IS the way currently accepted in the USA.

[njdevil281]

Aluminum came from planet earth you dumb fuck. It is an element not a British invention.

[theundeadx]

@njdevil281 yes, i know. we are talking about aluminium pronounciation, not where it came from..

[Printercupmouse]

@thekkl Yeah but Americans can't exactly give the world English lessons when they spell some things wrong anyway.



[thekkl]

@Printercupmouse If someone is right then they can be right regardless of the nation they are from.

[Printercupmouse]

@thekkl But it's not right, it's completely wrong. And only Americans do it. So in this case people are wrong because of the nation they come from.

[williaxim]

@ZXLNT  it is Al U MI NI UM

[seapeddler]

How can the customer be sure he does not receive a piston contaminated with semen.

[nbaalltheway]

all that for something small

[marek0086]

300 degrees C??

I thought max combustion chamber temp would be alot higher than that!

[jak4cars]

@marek0086

at the end of the video i started wondering the same thing, and a quick chech revealed that it is, much hotter

[marek0086]

@jak4cars~ so what is gasoline combustion temp??

[jak4cars]

@marek0086

i'm more awake now, it actually varies. flame from burning petrol is 471°-560°C but i think it can go to over 1000°C depending on air fuel ratio

[gman68137]

@marek0086 It also depends on compression, too.

[copperlocks1]

MAHLE !!!...wizards of aluminiun alloys

[marek0086]

@copperlocks1~NO!.... I'M the Wizard of aluminium alloys!

Muhahahahaha!!

[Thetruthishere11]

aluminum? We use that for beer cans. progress.

[lolPantsProductions]

Engines amaze me...

[NBSV1]

At first I didn't think it looked like an F1 piston since it was to big. Then after the final milling it looked more right. The failure on the normally is due to cracking from the high rpm and extreme heat from combustion. But they've been figuring it out pretty quickly and getting the temps down so they last longer. Now if only they'd go back to v12's.

[StefanR0]

@NBSV1 Sure it is a F1 piston! F1 engines have an enormous bore compared to the stroke (in fact the piston diameter is close to twice as big as the stroke!). This is needed for decreasing the piston's speed dramatically means for getting super high engine rpms. Another point is to get a very low circle crankshaft which increases the rpm also a lot. Take a figure skater doing pirouettes for example. Same thing when the leg is in and out.

[spiritcrusher923]

micrometers.. shit

[MoToMaN256]

we dewwelop and produce engine components

[NASTYTHEBOY]

very kool, i bet they cost an arm ang a leg, i woulndt sel my shit chea if it caost me that much work to make it :p

[serchmarc]

wow again

[BoZo325]

Is the german guy a gay???

[jamesandrew2000]

@BoZo325 His english is most likely as good as yours, hillbilly.

[monkeyboy85]

love stuff like this, makes you appreciate the hard work behind certain objects.

[gmarte12]

how much?

i was thinking of buying 4 for my kia

[Spadadiforza]

2:44 CMM inspection frequency is why you pay top dollar for certain production line of pistons.

[Spadadiforza]

0:49 performing FEA with a 3D cad system.

[bigjonnyjon]

cosworth make good pistons

[hairyshitter]

4 million explosion/combustions doesn't sound like much, did the guy make a mistake in the figures.

[KarriKoivusalo]

@hairyshitter

Not really. 4 million strokes on a formula one engine (from which the piston was from) equals to about 7,4 hours at FIA-regulated red line, considering the average RPM it would be more like 10 -12 hours. Since practice, qualifications and the actual heat per race equals to about 4 hours and the engine has to last two and with all the tune-in procedures needed, it does sound about right.

[hairyshitter]

Thanks for clearing that up, I suppose at the rpms F1/FIA run the pistons at they would wear very quickly due to extreme amounts of friction generated heat, these pistons would probably last forever in a standard road car.

[tathjones]

have they got a big enough ruby on their CMM? precision my arse

[Liist]

Background at 0:41

Looks an awful lot like my current classes :(

[DjRaveKing]

What people wouldnt show you .

Yes , Engineering Porno

[Sephirius]

Interesting, the model engine is a crossplane crank.

[behahve1]

Awesome. Engineering Pornography.

[defenderization]

The blue dye is called Engineers Blue. But it seems to have been mixed with Phosphorus to help glow in the dark.

[Chromatix]

its Fluoroscene, its been used for crack testing for 50 years, its different to blue

[defenderization]

You sound like you know more than me on the subject. somehow I did'nt think it would be Phosphorus.

[Chromatix]

our family has been in the business of building powerstations and more importantly turbines since the late 60's, its used for testing steam turbine blades too, no worries man!

[defenderization]

I just remember using something simular in metal shop on a YTS scheme a long time ago.

[tuca999]

...hahaha...da hört man den schwabe richtig raus..cooles video...

[Herooftheday64]

That model engine is soooo cool.

[Turbotrip]

Pistons without skirts???

[NobleLumpkin]

Lighter I guess.

[nickcars100]

less friction against the cylinder walls.....and yess that litttle bit is enough to give alot of power

[666williy666]

mite be to clear the rod as well i thingk

[lexichronicle]

but yea, that's about the cleanest workshop i've seen in a while. and mikron centres, nice...

[jonathan102]

the narrating voice is bloody annoying

[bobscanfly]

@jonathan102 he's probably the best English speaker of his country

[bob333336]

@bobscanfly You're ignorant if you truly believe that.

[Denime]

The narrators' voice is less annoying in 720p.

[Thesterness]

@jonathan102

He sounds like he's an Ossi.

[mashhead1000]

and slightly cheesy..:)

[topski100]

interesting, informative
