The cylinder kinda looks like a piston from a bigger engine :D

[@adenayoano4652]

it think so. man😂

[@dainyzas225544]

how did you do the ignition? I eman to get a spark

[@Astopanto]

Ciao, ottimo lavoro... Volevo chiederti se potevi fare un video dove spieghi come hai fatto, come l'hai costruito e soprattutto il montaggio... Grazie...

[@Sun-e]

I love engines

[@danielmichalski94]

Nice thumper, bro! :D Wery well made... It sounds like a engine from chopper motorcycle :3

[@BigFiveJack]

I'm sure you're very satisfied that it runs so very well!

Sempre interessante e amatoriale Costruzione !!!!

[@kiranyonzon2537]

can u make avideo of inside mechanism... parts at the top?? please

[@marteloficina]

Nice engine! But you build this engine based in another engine or you build this alone whitout any plans?

[@robert1352]

Well done!!

[@mikeandrews4901]

I didn't think it would run very long giving the slop in the rod bearing. Impressive!

[@gwheyduke]

Sounds good !

[@AncapistanVan]

Wow and it even has variable valve timing :P Excellent work very impressive

[@paolofedrighini7363]

0°:Piston at TDP; intake vale opens=begin intake stroke---70°:Intake valve closes=end gas mix intake-- -90°: Piston at BDP=end intake stroke& begin compression stroke. 180°:Piston at TDP=end compression stroke; spark (o r fraction earlier)---250°:exhaust valve opens=begin exhaust stroke---355°:exhaust valve closes---360° (=0°): process repeats

[@Alexie3333]

So you have a intake duration of 180 degrees. and for the exhaust 110. Could you explain why the exhaust have a shorter duration? The duration 0f 180 degrees for the intake looks fair, because better volumetric eff. in lower rpm. At the moment I'm building a 1 cil. But are looking for intake and exhaust duration of 200-220 degrees. For aiming rpm target 2500-3000 rpm

[@Alexie3333]

Does the cams have bowl or straight flanks?

[@sahibbhullar9838]

Good made bro i like it so much

[@AungAung-ow5sx]

Great work. I am building model 4 stroke engine. But it doesn't run yet. Can you tell me compression ratio of your engine.

[@edwinnoheamayavega2237]

Me encanta tu invento 👍 te felicito por tu intelijencia

[@rconger24]

Awesome!

[@moisesdjovey1640]

Intersante pequeño pero con estilo propio, saludos y gracias.

[@Tasaconga]

Podrás explicar como funciona el sistema de alimentación. Gracias

[@LeonardoPTomaz]

Pelo que eu entendo , o cabeçote é oco e dividido em duas partes , a da adimição e da exaustão.as válvulas têm o formato de pregos . Quando o pistão desce a válvula abre-se e como o pistão está descendo a pressão na Câmara de exploração diminui e faz com que o combustível entra. Quando o pistão começa a subir a válvula de admissão se fecha o pistão sobe comprime o combustível e logo após o pistão ultrapassar seu ponto mais alto a vela de ignição produza uma faísca que queima a mistura provocando o alimento de gases que empurra o pistão para baixo. Após a Queima o pistão desce e começa a subir novamente , é quando a válvula de escape se abre e o pistão empurra a mistura para fora da câmara da camara. Note que o motor realiza seu ciclo completo em 4 tempos o que dá nome do motor . Para que você consiga sincronizar o tempo das válvulas você deve fazer com que. O eixo que sai da árvore de manivelas tenha metade do tamanho do eixo que movimenta as válvulas ou seja: para cada2 giros do eixo motriz o eixo que comanda as válvulas girar apenas uma vez pois as válvulas de admissão e exaustão têm que abrir e fechar uma vez para cada dois giros do eixo motor . Espero ter ajudado esse é meu conhecimento que tenho , geralmente eu conserto motos não como trabalho mas sim como hobi

[@shinigami1315]

It's beautiful 😢

[@henkjekel4081]

how do you get that sound, I dont hear this great sound with other 4 stroke homemade engines on youtube?

[@Boris_1421]

No muffler

[@harshdeepprince8684]

where from we can buy this?

[@merich4940]

I dig it!

[@djzatka]

How you made this ?

Nice information about a engine

niiiiiiice!!!👏👏👏

[@user-yi8if2il4l]

How many teeth of gear timing?

[@mariorossi2892]

Ottimo lavoro. Volevo sapere quale è stata la difficoltà maggiore nella realizzazione del motore e soprattutto come hai realizzato l'accoppiamento pistone cilindro. Qual'è la cilindrata di questo motore? Grazie e ancora complimenti

[@paolofedrighini7363]

grazie, la maggiore difficoltà sta proprio nel realizzare l'accoppiamento pistone (aluminio) - cilindro (ghisa). Prima fai il cilindro e fai una super lappatura poi realizzi il pistone. Nel mio caso come fascia elastica ho utilizzato un'OR per alte temperature (è arancione, lo si trova ovunque), viene commercializzato come Viton. Funziona meglio che una fascia elastica in ghisa (abbastanza difficile da realizzare). Fai conto che il mese scorso ho tenuto acceso il motore per 3 ore consecutive. Smontato e verificato l'accoppiamento.. ancora perfetto. Il pistone ha un diametro di 25mm e una corsa di 24mm, Al minimo sta sui 600 rpm al massimo 3500. Tra il disegno cad e la realizzazione, avendo poco tempo a disposizione, è passato circa un'anno. La soddisfazione che si prova al primo avvio ripaga il tempo trascorso per questo "semplice motore". Ora mi sto dedicando al disegno di un V4 sempre 4 tempi. Ciao

[@warmerthread983officialcha9]

Molto bello

[@nakkimonssi9762]

is the cylinder and head Just one piece?

[@theeoddments960]

How does someone do this?

[@eugene251]

so beautifull engine,it is like a futuristic home generator

[@camb9696]

is the head a piston?

[@yasons9531]

how you maked this have you plan can you send me a plan

[@harshdeepprince8684]

how we can make this or

[@kevingooley6189]

Niece work.

[@ALLENWERK]

Very nice build! Which one of Jan's plans did you use? Thanks!

[@paolofedrighini7363]

otto four-stroke engine , ciao

[@marvinulrich1072]

Pretty nice

[@shubhamsinghgour6659]

How u make this

[@driveitbreakitfixit7496]

How much teeth on each gear for the timing? And awesome engine!

[@dawsonwood7870]

the actual amount of teeth is insignificant, its only the ratio that counts. Its a four stroke engine, so intake compression power exhaust. intake is piston going from tdc to bdc (tdc is top dead center and bdc is bottom dead center) and then compression is piston going up to tdc again. So thats one revolution for two of the four strokes. then power is when combustion forces the piston down, going from tdc to bdc, and exhaust is from bdc to tdc. now keep in mind thats two revolutions of the crankshaft, while the valves only opened once. (each).Thus the camshaft needs to rotate at half the speed of the crankshaft to achieve opening the valves once per two engine rotations. So you would need to have the gear on the camshaft have twice the teeth than the one on the crankshaft. if you're off by one tooth, it would pull itself out of time after a couple rotations, and if its an interference motor, could suffer catastrophically. So in short, Half the amount of teeth on crankshaft than on camshaft.

[@driveitbreakitfixit7496]

Dawson Wood I know that but what's the ratio

[@dawsonwood7870]

2-1. every one tooth on the crankshaft would have to have two on the cam. hope this helps. so if you had 15 on the crank you would need 30 on the cam

[@robinhooodvsyou]

I love it.

[@paolofedrighini7363]

thanks

[@endtasid]

very nice. congrats. what about cooling and oiling the engine? how do you do it?

[@carmelofarrugia5855]

oil is added to the fuel for lubrication of piston & cylinder . cooling can easily be done with a copper pipe coiled on the cylinder head with water dripping. mind you this is for demonstration purpose which means it's meant to run for a short time. A very good engine I've started mine with a 30mm diameter piston ,

[@endtasid]

very well done.

[@dontjudgeme2736]

carmelo farrugia wouldn't that make it a two stroke

[@arumuttumurali6925]

Could u share the plan to me i would like to do

[@GarikDonagafonovich]

kzbin.info/www/bejne/jZXHq3aDpJiFhs0

[@trb.a]

Super acest motor.

[@Tasaconga]

Excelente. Can you explain how work the fuel system..? Thancks

[@gediegengegonnt31]

As far as i understood the air is beeing sucked in by the cylinder through the blue tube, which forces the air to flow through the petrol, which causes bubbles and more petrol gases. These fumes or petrol air gases are then sucked into the cylinder through the transparent tubing.

[@Tasaconga]

@@gediegengegonnt31 Thanks... Excelent..!

[@Tasaconga]

@@gediegengegonnt31 Excelent

[@TheMasterizzatore]

Ciao, ottimo lavoro. Ma l'albero a camme l'hai fatto te oppure è recuperato da qualche motore?

[@paolofedrighini7363]

Anche quello fatto da me.. disegnato in cad e realizzato con la mia cnc. Una delle parti più semplici. Inoltre le due cam non sono uguali: quella di scarico mantiene la valvola aperta per più tempo. Ciaoo

[@marioaureli7301]

molto bello

[@Skoda130]

But how is it cooled?

[@MyJigarpatel]

Nice engine.

[@LCMNUNES1962]

MUITO LEGAL ESSE MOTOR, BRASIL OK.

[@vinhpham9241]

The engine very nice. What's the type ignition system ? Hall sensor or breaker point ignition. Thanks you 🏎🏎👍

[@paolofedrighini7363]

Hall sensor. Rcexl ignition CDI for CM6 spark plug

[@vinhpham9241]

Thanks!

[@captainprototype187]

Is the piston sucking up the fuel inside a chamber? Combustion chamber, I think. Or carburator.... Never tinkered with an engine, unfortunately. Never had the chance.

[@DarkorbitKing100]

Never too late to start

[@jeepwrangled79]

What's the gear ratio on the cam?

[@paolofedrighini7363]

crankshaft to camshaft gear ratio is 2:1

[@musanaveedmusa3805]

nice

[@GoingtoHecq]

this thing sounds like a jackhammer, complete with clattering metal.

[@valentinemarnane4687]

did you make it or buy a kit ?
