4 cylinder engine animation

[sputnik225]

I can see the power band!

[paulhunter123]

how does the camshaft rotate at half crank speed?

[codene]

@paulhunter123: the chain sprocket on the crankshaft is half the size (has half the number of teeth and is half the diameter) of the chain sprocket on the camshaft. Thus, for every two complete rotations of the crankshaft the camshaft turns only one rotation.

[tiyochupantio]

4 stroke cycle is 1. in take 2. compression 3.power 4. exhouse.... hahahahhahaha

[tiyochupantio]

all both exause and intake manifold hahhahahahaha

[billseyenyou]

It is hell to service

[pacog92]

what is the difference between this and a parallel engine???

[andregomesnf]

I'm glad I'm getting Mechanical Engineering degree =D

[abigailgeli]

must be better if you did a roller chain for long run

[TheLuke2reeve]

nice never seen a timing chain in the middle first for me i like it

[FireworksDude311]

ok just one question?

are we seeing the intake cam/valves or exhaust cam/valves. I am not able to determine witch strokes we on on at what time. I know it is a 16 valve DOHC, but witch side are we seeing from the front, intake or exhaust?

[timorbit]

@FireworksDude311 You are still able to determine which strokes it is on by the information given. If the valves are open and the cylinder is going down, that's obviously the intake stroke. Valves closed, cylinder coming up = compression. Valves closed, cylinder going down = combustion. Valves open, cylinder going up = exhaust. From this you can follow the pattern. The cams in front are the intake cams (you can see the rear cams one stroke ahead of the front ones, from the exhaust cycle).

[rubberbandman03]

everyone stfu and study the video, the inlet valves are opening at the same time and exhaust are opening at the same time if u look carefully u can see the next set of valves are behind the first set,LOOOKK

[rubberbandman03]

ITS INTAKE COMPRESSION COMBUSTION and EXHAUST

[rubberbandman03]

not every cylinder gets 4 valves, some only have two one for intake and one for exhaust, read buddy

[marq101]

Very common on older motorcycle engines

[legomaniacman]

I never seen a center cam chain on an engine, must be hell to service

[Bamchucknorris]

lol they need to split the block in half to oil the cam chain lol

[archetype891]

@Bamchucknorris or maybe japanese motorcycle engines lube the chain with their own oil

[Bamchucknorris]

@archetype891 or maybe the design is terrible because the chain is right between cylinder's, exposing it to alot more heat and if it breaks, good luck servicing it!

[archetype891]

@Bamchucknorris or maybe the chain is cooled by the oil and japanese 4 cylinder engines are some of the most reliable engines ever made

[Bamchucknorris]

@archetype891 or maybe you should shut the fuck up and stop throwing out opinions

[archetype891]

@Bamchucknorris aww red nekkuh upset :( much darkness in your heart

[Bamchucknorris]

@archetype891 not really, I dont live in southern north america. And i approve of all motors, but (opinion time warning) a chain between the cylinder is a stupid fucking idea.

[GerwinPlanet]

@Bamchucknorris Ofcourse it is. Maybe you should apply for a job at Honda and tell them! It will be a revelation to them.

[master777999]

@legomaniacman A lot of old Japanese 4 cylinder motorcycle engines had a center cam chain like this

[VidsYouMustSee]

@legomaniacman lol

[Blazen8gsx]

@legomaniacman it's on motorcycles

[thugkilla1212]

every cylinder gets 4 valves im 12 and i no all dis go learn sumthing!

[RifledBarrel]

your asses are 16 valve you dumb-wipes

[evo7lika]

It is 16 valve.

[727Dexter]

this is false!! the valve are not syncron

[enjoiDrum96]

not that great animation i am 13 years old and i no that this is wrong

[chabbalato]

fantastic.... lets hope no one would ever need to change a timing chain on this thing

[LaFamilia4live]

It is a 16 valve

[Isus666999]

Maybe it's a 16 valve XD

[manmari333]

thats cool

[JPMADDOG1]

wrong both valves dont drop at the same time, the inlet comes down lets an air fuel mixture in and the valve closes the plug fires the engine makes a compression stroke the exhaust valve opens.

[2Redrider1]

intake-compression-power-exhau­st, not intake-compression-exhaust

[jlljhfe]

lol, look carefully and u can see that it actually has two cam shafts, the animation is right, just a bit confusing tho is u dont look carefully

[Lordcampi30]

very shit video i think,all wrong :P

[Totenhosen17]

Actually, its a 16 valve, so your wrong twice, once about the video, and once about what you just said

Its intake compression power exhaust, not intake power compression exhaust.

[krenogin]

It is a 16 valve. Its just 2 dimensional, you can see both sets of lifters, the intake, then the exhaust right after.

[Totenhosen17]

That's what i just said.

[shaikhdishgan1]

tou have to use 8 v so pepole understand outo ci.

[fendt818turbo]

this isnt wrong, its a 16v, 2 inlet and 2 outlet valves per piston~! i tink

[loplanic89]

Its true

[vegitarean44]

whats that thing in the middle like a belt?

[conorjackman]

timing chain

[vegitarean44]

oh so does that thing connect to the speed meter?

[alex1234201]

Connects to the camshaft gear so the valves open at the precise moment with the pistons.

[Lordcampi30]

lol thats bad.the valves open at same time lol

[maverickjess]

very nice..

[nustangchristian]

looks like a ricer engine

[rogelead]

this is wrong

[black200sxser]

WHERE IS THE V TEC

[myanka1]

hmm hmm...the inlet and outlet valves are openin up together ..and thats not right...

[bpoteat]

No, there are 4 valves per cylinder two for intake and two for exhaust, so two are always two opening together either close or far. Study it more closely.

[roycehellion]

yup what do ya know, i missed it at first too, but your right its correct.

[drradicalcris]

that's wrong:)

[vicecity000000000]

changing that cam chain would be a bitch

[alphacat626]

true, plus on the right side of the engine he has the teeth that he could attach a timing chain to.

[Appledude500]

and how do i know when cam-shaft is in place? does this system got marks on cogwheels?

[LISYANDY]

Este video no muestra bien el funcionamiento de el ñarbol de lebas, ya que las valvulas de admición y expulción (en este video) se abren al mismo tiempo, y eso implica que la mezcla aire combustible no se podría comprimir, y la expoción sería en vano. El funcionamiento de las valvulas de admición y expulción se abren en distinto memento.

[vasconogueira]

É um motor de 16 válvulas(twin cam), repara que abrem duas válvulas a frente e depois duas a atrás.

[rjscott2007]

dont they call that  dual cam? cause it needs two cam shafts to operate all 4 valves

[XELA2T]

@rjscott2007

officially this is called a DOHC -Double Overhead Camshaft -engine. Those with a single overhead camshaft are usually named OHC engines.

[justinmcburney]

yeah its right 2 intake valves and 2 exaust valves but because its the side view you cant see the other 2

[Th3Gr33k]

Do a Vee twin they are the best :D

[jayguy173]

hes right the intake and exaust valves open sepratly

[legonoitall]

no it has to inlet valves and 2 exuasht valves look closely as the overlap in the animation.

[gwilouk]

This video is stupid, the valves open at the same time. They open seperatly

[codene]

This is a 4-valve-per-cylinder engine. Note that the view is from the rear, and yes - the two intake valves open at the same time. If you observe closely, you'll notice that the two exhaust valves open at the same time as well, albeit at a different time from the intakes, of course.

[gwilouk]

I thought that might be that way, however, as an illustration seen from the front it is a bit useless and confusing to someone who never saw an engine.. Sorry to say!

[codene]

Yes, I've thought of that as well. I'm currently working on a 3-D animation that will be easier to understand. Thanks for your input.

[Schublade45]

16 valve engine.

[BarPlayList]

@gwilouk

look more closely, its a 16v so there are two inlet valves and two exhaust valves!!!

[celraysoda]

I know that a 79 Kawasaki KZ650 has the chain.

[Fingerf1]

Hi. Do engines with the chain inside (between the cylinders) really exist?

[codene]

Yes - many motorcycles use this configuration. (See your personal messages for more info.)

[v12revolver]

no i dont think so, i belive its just a simple v wit a small camshaft and a lobe with 2 lumps for intake and 2 for exhause stage

[666host]

@codene

And how can you change the chain? you can ,,disconnect" the chain? or you must ,,unscramble" the engine? thanks

[DJCocknCream]

@codene chain inside the engine nooooooo at front be clever and one question where is the oil ? in my opinion you give it a serious consideration with your layout of the engine.

[SebNormandy]

Old suz gsxr and 1200 bandit have chain at this place

[adv512]

the chain is connected to the crankshaft and it turns the cam up above the cylinder's altho its usualy on the front of the engine witch gives the term SOHC or DOHC (singleduel over head cam)
