minature V12 gasoline IC engine
« on: September 07, 2021, 09:47:32 AM »
Hello everyone,

I am from China and would like to introduce my mini V12 engine. it runs on gasoline. the dimension is L 200mm x W 110mm x H 150mm. it has a capacity of 49cc and delivers up to 8hp. it doesn't have a prototype. It is fabricated using CNC. Roughly speaking, it is 1/8 scale. I put a video on youtube: <a href="https://www.youtube.com/watch?v=inWZpHkyowQ" target="_blank">http://www.youtube.com/watch?v=inWZpHkyowQ</a>

Wow!  Very nice!
So was this a kit of some kind? Or did you design and build each part?

I am plagued by emails from a Chinese company called Stirlingkit. They try to sell me various model i/c engine kits similar to this.
Is this one of their products?
Do you know that company?

Hi Kim,

Thanks for asking. This is OHV type. I designed it and made it.

Hi Trevorc,

I heard of this company, but don't deal with them. This product is mine, and newly rolled out.

breadf, Nice engine.

Do you have any photos of the parts actually being machined by yourself ?

Hi Mike,

this unit is made by 3D printing and CNC fabrication. i just designed it and outsourced the fabrication. If i could successfully bing it to mass production, i'll only use CNC fabrication.

Hello Rhett / breadf,

Thank you, Now I understand.

You have made an excellent design, a V12 is not an easy engine.

It is good that you can outsource the 3D printing and CNC machining, if you cannot do all the machine work yourself. It is quicker but more expensive than doing it yourself.

Do you have plans to bring the V12 engine into mass production? Do you have an indication of the cost of the V12 engine, as a kit of parts. Also, an indication of the cost of a fully assembled engine?

Do you have a selling agent?

It looks to be a beautifully designed and well manufactured engine, so it could become a popular kit for model engine builders.

Regards

Mike

Hi Mike,

Thanks for reply. Yes we hope to bring this into mass production. We are gathering orders. If we could have 30pcs totally, then we can start the production. Agent is a good idea, but at present we don't have oversea agent. We just rolled it out and few people know it yet. I hope more people could see my video and this post.

Regarding the pricing, could you leave your email? I'll reply from there. Thanks.

Have a good time,

Rhett

That's some excellent work  :ThumbsUp:  :ThumbsUp: Is the carburettor a commercial unit?
Best regards

Hello Roger,

I'm pretty certain it is a copy of a Walbro WY series , rotary barrel, diaphragm carburetor. Which specific model no, I cannot tell, as there are a number of different choke diameters in the WY series.

I have a WYK-33 fitted to my Honda GX32 tank engine and also to one of my Bristol Mercury engines. I think they are one of the best diaphragm carbs available. They run straight out of the box and I have never needed to touch the two factory set adjustment screws. The rotary barrel rotates and lifts when the throttle is opened, this lifts the needle to give more fuel as the revs increase. It does that rather well. I would recommend a WYK for any engine over about 20/ 25cc. They are dirt cheap on e-bay

Seriously, a fantastic job.  Well done!
