  A serious demonstration of machine competence, in Spanish ....I think.

That is indeed in Spanish. It is not stated what country Jesus Wilder lives in: most likely Spain, Argentina or Mexico.

There was no radiator, and I did not see how lubrication would be effected.

This is a masterpiece, anyway.

   What is an "Enfriador de agua dulce"?

      I want to say "sweet water cooler " but that makes no sense really.



       Bombas refrigeration seems to be coolant pump or coolant compressor.

        Colorectores de admission and coloctores de escape look like the intake and the exaust manifold.

       It has no water jacket , so I think those little pumps are for lubricant.

        It has no electrical system , and I see no smoke nor steam so I think he is making it run with compressed air. Compressed air motors do not require much cooling , especially at this scale.

      What a little jewel it is!

       For little more effort he could have made a full size engine and thrown it in a car.

       At the end is the card saying that he spent more than a thousand hours working on it?

[Xavier_Onassis]

No, the [pumps are for coolant, namely agua dulce, which is what water without salt is called. It did have a cooling system, but when it was running, I did not see how it worked.

    That makes more sense , but there isn't a radiator and I did not see a water jacket so there is still a mystery about where that cooling water circulates.

    I am pretty sure he is spinning it with compressed air , making it a motor , but not an engine.

[Xavier_Onassis]

It might well be that is is spinning with compressed air. I see no carburetor, fuel injector system or fuel coming from anywhere. There are no spark plugs and no Diesel pump. So it does not need a cooling system as there is no combustion going on. Just a bit of water seems to be needed to cool it from any friction caused.

So I think you are right.
