How It's Made Engine Pistons

[daniel0771]

robots do all of the work yet we still pay a shit ton of money for them.

[evets433]

@daniel0771 Some One still has to be paid to programm the machines, which is all done on cam now )CAM=Computer Aided Machining, and before that they need to be designed, then there is the initial cost of the machines, the running cost of the machines, the cost of the billets of metal , tooling for the machines, testing and the list goes on :D

[daniel0771]

@evets433 you and your logical answers!!!!!!!!

[olive1913]

"even up to 6k rpm" my 2 stroke gets up to 15k :D

[brainiac409]

all that fancy machine work & the guy takes out his pocket knife to it!!

CrikeyMang ,thank you :)

[kawibbyrule]

are these wiseco pistons? i know they use fordge pistons

[flymanryan]

how F@@KING EXCITING



[GeorgiaGeorgia8D]

forged pistons are where its at

[ACHEESEDANISH00]

@GeorgiaGeorgia8D correction billet pistons with ceramic coatings on the skirts are where its at... that is if you have 2500 bucks just for pistons!

gini ternyata cara bikin piston cckckckckc

[bassdownlow007]

@undeadkillers thank you for replying :)

[bassdownlow007]

can anyone tell me which is the best material to be used to make piston and why? Thanks :)

[undeadkillers]

@bassdownlow007 Well if you want the pistons to be rediculously strong then steel is the best option. If you're looking at low weight (low weight = less mass that has to move up and down thousands of times per a minute) and still strong then an aluminum alloy is the best option. If you want something in between in terms of being cheap and realiable then iron is the way. It's highly variable upon what YOU want the engine to do.

[CrikeyMang]

@bassdownlow007 Aluminum pistons is the way to go. Strong, lightweight, and affordable. Going any other route as far as material-wise you would just end up spending more. I guess I cant even remember the last time I seen a piston that wasnt aluminum. Hope that helps. :)

My dick is ready for Ups and Downs too! xD

[Neflyte300zx]

can someone explain if there are any diference in power from a small diameter piston than a piston with twice or more times the diameter?

[Kilohercas]

@Neflyte300zx

more Nm (torque)

power will be grater, but smaller size can do more rpm with same amount of fuel.

in short, you win just Nm

[marek0086]

@Kilohercas~ Thats absolute rubbish. U dont know what you're talking about!

[faziljaved]

@Neflyte300zx if we consider two pistons of the same cc cylinder, one is bigger in dia and other is smaller in dia, then the bigger dia piston is likely to produce higher rpms cuz the crank also has small dia and this setup will likely to produce more horse power. on the other hand the piston with smaller dia will have longer stroke results in more torque but lesser rpms and horse power. it all depends what kind of engine it is for. different engines require different kind of pistons.

[mikeb1444]

@Neflyte300zx

For one, a larger piston isn't going to be able to take high RPM abuse. One thing you do get though is more effective pressure on the piston, which gives you more torque. It's actually a very complicated question. Rod length and crank stroke have a lot to do with it.

[yourmistress007]

@Neflyte300zx Just increasing the diameter is the piston increases the size of the combustion chamber, which means you need more air and fuel and thus you get a bigger bang. If you want to increase the rpm you would increase the bore to stroke ratio. For example, a conventional production engine will have a bore to stroke ratio of around 1, or normally with a slightly longer stroke. An F1 or motogp engine has a ratio of 2 or more. If you increase the stroke length, torque increases

[CrikeyMang]

@yourmistress007 I think you slightly mis-worded a portion or I read it wrong. Slight correction. Increasing boresize does not increase the size of the combustion chamber. It increases swept volume allowing more air/fuel to be compressed therefore increasing the compression ratio & torque ever so slightly. I think thats what you meant to say. Everything else was spot on. Cheers! :D

[Niggagonnadie]

@Neflyte300zx bigger piston bigger boom more power

[desein7]

@Neflyte300zx Smaller piston engines can reach higher roatations per minutes Bigger means more Nm or torque

[TheDarwiniser]

@Neflyte300zx

a bigger piston means more weight to move, which in turn means it must rev slower or it will break something.

this is called piston speed.

power is determined by torque and rpm, so it follows if you have really high power you must have high torque and/or high revs.

a larger diameter piston will give more surface area and volume for a bigger fuel charge, this works best as lower revs with high torque giving similar power to a smaller piston revving much faster.

[JonEldred]

@Neflyte300zx Anytime you increase bore (piston width) you increase displacement of the engine. With increased displacement comes a larger air/fuel mixture. Both power and torque usually are increased with more displacement. A longer stroke effectively gives you more lower rpm power, because the piston has been given more leverage and therefor a mechanical advantage. A larger bore will tend to increase the peak of the powerband further in the rpm range...

[JonEldred]

@JonEldred A smaller piston will lower displacement and for the most part, lower power. A smaller piston does usually weigh less and this will allow the engine to rev higher (more power, not more nm / ft/lbs). Higher revving can be achieved with a smaller stroke as the piston won't have to travel as far in a single revolution and place less stress on the rods and crank.

[moh97gt]

@Neflyte300zx think of it as it is a sailboat - if the sail is big or small in the same boat weight with the same wind speed ,but the stroke length also effect the power and the stroke & bore ratio wither it is oversquared or undersquared engine for the same CC , for the undersquared it get high torque at low rpm and for the oversquared you get low torque at low rpm but the acceleration is better

[itachiitachi1946]

nice video..BUT id like to see and learn how those machines/robots that convert the metal and all that stuff r made.step by step a long lasting video explaining it from zero point to full complete.that would be nice

[datzfast]

9000 diffrent ones? well that must be all the dirrerent ones in the world.

[z0ne276]

@datzfast every engine type need a special sized piston, if you rebore a cylinder you need a bigger piston.

[Arabhacks]

It depends on the size of the engine.

A large ship engine might only do 800 RPM.

Small model engines may do 30 thousand RPM.

Larger big truck engines may redline at 5 thousand.

[Kilohercas]

well, not lot of people use high rpm while driving, so that's normal

i never used more than 5000rmp on diesel engine so far... :)

[iToasterman]

@Kilohercas rmp....?

[BlueRice]

@Kilohercas i drive a civic, i use higher rpm for the lack of torque. the rpm rev much faster than engine with bigger piston. so it balance out.

[skinlicious43]

@Kilohercas You shouldn't need to use more than that on standard diesel engines. It's quite common for smaller petrol engines (i.e. 4 cylinder) to rev to 9000rpm or more.

[Tecnogas69]

3:38 6000 times per minute ? Ridiculous, even a diesel engine can move up to 7000 per minute...

[cyberbadger]

@Tecnogas69 My 2010 Volkswagen TDI (Turbo Diesel) redlines at 5000 RPM. Arabhacks is right - it depends on the size of the engine, cylinder diameter, and stroke length. Nascar gasoline engines have a very small stroke, but they run at 20,000 RPM. Big ship diesel engines may run at 700 or so RPM.

[xXturbo86Xx]

@cyberbadger Nascar? 20k rpm? NO. that would be F1 engines not nascar engines

[cyberbadger]

@xXturbo86Xx I stand corrected - it's the F1 engines that get near that RPM.

[EthansRidealongs]

@cyberbadger dude, a nascar engine dosnt even come anywhere near close to 20k rpms, when we dyno the engines we only get it up to 8,000 rpms the highest they get is around is maybe 9500 if the driver is pushing it, but if they keep it that way, The engine gives out and they lose the race because of a DNF. Oh BTW Im a Graduate of Nascar Technical Institute in Mooresville, NC.. so im not pulling this all out of my ass.

[cyberbadger]

@EthansRidealongs Like xXturbo86Xx pointed out - I stand corrected - it's the F1 engines that get near that RPM.

[cyberbadger]

@cyberbadger I stand corrected by xXturbo86Xx and EthansRidealongs - It's the Formula One engines that get near 20,000RPM - Not Nascar.

[cyberbadger]

@cyberbadger However the point is engine RPM depends on the engine size and configuration. Cylinder diameter (bore) and stroke length (How far the piston moves from the very bottom to the very top of it's travel) plays a huge part in it's operating revolution per minute rate (RPM). This may vary between a few hundreds of times a minutes to tens of thousands of times a minute.
