3D Engine Displacement Video - English units

[GMulheir1]

brilliant video! 

[rd0769]

I didn't got how bore dia (3.75/2)^2 becomes (3.516)^2.any conversion? like inches to m ? or what?

[bandicoot000]

@rd0769 Good catch! The square should actually be removed from the number... 3.516 is (3.75/2)^2. I'll try to fix it.

[tiagonestiago]

I will use it in my class, and will tell you how it was. I think it is great work, but I would prefer the term "cylinder displacement" than "piston displacement". Thank you for the video!

o sry ^^ my bad inglish i thaught TORQUE ^^ sry

[unclewilly2]

how is the formula for NM ???

[nemanume]

Please tell me the name of the program ...

I teach engine technology in the UK, i wanted to use this for a class, but could you make a metric version?

[bandicoot000]

@RedReggub Thanks for reminding me, I made a metric version at the same time I made this one. I just uploaded it, so it should be live shortly.

152.4 in³ = 2,497cm³ or a 2.5L engine

4 cylinders in one motor,,,

why 2 up and 2 down,,,

not good idea,,,

better use 4 different cylinders positions height like 1, 1/4, 1/2, 3/4

[btownmxer]

@bestamerica Its called companion cylinders. While the number one piston is at tdc on the compression stroke its companion cylinder which just happens to be cylinder number four on this design is on tdc also but it is in overlap. Most american engine designs are like this. If you take the firing order say its 1,3,4,2 you stack it to find companions

13

42

one and four being companions and three and two being companions firing 180 degrees apart.

Thank you sooo much for this video.  This helps out a lot

[revhard05]

ar you going to build the head and valve train?

[wecametobelieve]

did you use solidworks for the modeling? what video software did you use to build the video?

[2jzgtejza80]

I'm using the catia nad solidworks...but solid is better 4 me..and coast much less than catia...

[bandicoot000]

I used Autodesk Inventor for the modeling and Inventor Studio for the rendering.

[Finky101]

where did you get the exact dimensions for the engine??..i want to model one on inventor aswell but don't know where to get all the dimensions..

thx

[tarrizzzzzzzzz]

hey its cool, but an engine has never more than one cylinder at the top/bottom at the time... yours number 1 and 4/2 and 3 are parallel

[TransAmLuvr]

tarizzz......wrong! While #1 & #4 cylinder may be on compression or exhaust stroke, (both TDC), #2 & #3 would be on the intake or combustion stroke, (both BDC). The sequence: Intake, compression, combustion, exhaust. 4 cycles, hence the name.

[racingisfun]

ur wrong...

[heftycat]

i agree - any 4 cyl that ive ever worked on doesn't work like this either... for longevity and balance purposes to the shaft... ive always known them to be 1324 sequence... alternating exhaust/intake strokes... again, for balance on the shaft. Or else you exert more moments of stress than is neccesary in the middle of the shaft's span... You can find animations of a bugatti w16 where the scene above doesn't seem to occur. That's 16 cyl man. I've never seen them like this is all I'm adding.

it's 'To Zanarkand' from the FFX soundtrack.

[brendonv101]

Piston only had 2 rings when it should have 3. Not good enough :(.

[theriontom]

Exactly 4 rings must have...2 compression rings and 2 oil rings.

[wikkidwonka]

nah, 3 is correct. 2 compression rings, 1 oil ring.

[theriontom]

My Honda Integra TR have 4 rings...

[wecametobelieve]

my chevy 350 has the same 3 rings the designer of this illustration shows. this is an excellent demo

[31okskoolmuscle31]

thats a nasty stroke for a 4 cylinder!!!!

[OLTCITKA]

Great video and really informative!Thank you!!! ;)

[cursevirus]

very nice. gives us good hard information

[peaweasel]

Very nice and informative!

[cupmike]

So thats what that stroke thing means

[JTC90]

Thats a huge displacement for a 4 cylinder

[usbcd360]

154.2 cubic inches is about 2.5L, which is reasonable for an I4.

[Niller3253]

yep, Porsche has made both 2.5 and 3.0 litre 4 bangers. (2.5 in the 944 and 3.0 in the 968)

[theriontom]

3.0 I4 is too bad...2.5 is limit for I4. 3.0 can be 6

[laputadetuhernana]

exelente
