Smallest v12 engine?

Post by Skynyrd »

Hand made compressed air v12 engine.

Man I'd love to have the time and the craftmanship this spanish dude has to build his own mini v12. Beautiful work.

Kuddos to him :thumbup:

Beautiful. I wish I had the skills, time and kit to do that.

Can someone please tell me what the "enfriador de agua dulce" is?


Is that an old clip? it is a pushrod engine and would have saved much work to have made it an hc. Is it a copy of an actual motor maybe?

It's the water cooler. I'm not sure, watching the video, what it cools or how it works though.

The v12 in the video is for a scaled ship model so it is probably a copy of an actual naval engine. Don't know too much about the industry to be sure though.

Well its a compressed air engine. It says on the video description that it was made for educational purposes and the decision to use compressed air is to make it cleaner but being naval I guess the real engine would be diesel yes.

I'm in awe of the man's skill.

I've love to see it mounted on something and making it move!

Very hard to say this, without sounding like I'm knocking the blokes engineering skill, but an engine that runs on compressed air isn't a technical masterpiece (while it definitely is a machining work of art.) Doing my degree we had to machine a single cylinder compressed air engine, the measure of its design being the minimum psi that was required to keep it idling/not stalling.

A [very] long time ago one of the many Clarkson's programs contained a piece on someone who built a scale model Ferrari.
He spent some stupendously long time making it. Gonna Google it.

Never mind the machine tools, I'd love the spare time to do it, and the fact my wife wouldn't leave me :)

These model-makers have such engineering understanding, machining skills, good eyesight and unshaky hands! Fantastic model.
Off topic: the smallest full-size GP V12 engine I can think of was the 1964-5 Ferrari flat-12. Even more incredible was the 1949-54 BRM V16 of 1.5-litres.

8O Did they use thimbles for pistons?

Not really, the stroke was 47.8mm so the diameter of the the pistons was just under 50mm

in the early 60s honda made race bikes with 4 stroke 4 valve per cylinder 50cc twins such as the RC115

I was obviously employing a bit over hyperbole there. :)
But still you got to admit that 50mm (~2") is a mighty small piston in a car.

I bet that thing revved like hell.

Looks like 12 cylinders isn't enough, here are two videos, one about a W-18 and the other 16 cylinders in 4 banks.

That is gorgeous, sloth - the commitment this guy put towards building the car is unbelievable! Great find!

This is the kind of thing I'd love to be good at doing. Unfortunately, I definitely couldn't be bothered with spending the countless hours practising and learning to get this good.

Pretty cool.

In a not really very related note, I saw a Merline V12 engine at the Imperial War Museum in London last week. It wasn't small but my god it looked fantastic. This engine, amongst other uses, was the one that powered the Spitfire.

speaking of engines in museums there is a brm v16, cut away so you can see the size of the pistons, in the GP collection at Donington.
