Worlds Smallest Running Engine

Somebody has too much time on their hands.

He should rename it smallest petroleum fuel based engine.

 

Very cool.



Here's a guy that took 15 years to hand make a complete, fully functional, 1:3 replica of a Ferrari 312 PB. Amazing.

Out of curiosity. Anybody know the horsepower rating for these engines ?

I know it's miniscule. But it seems it would be much higher than the other engines of comparable size.

 

These are nothing new. There are several vids on youtube thats been out for a few year's. The german's are known most for making them.

 

2 to 8 hp.I know some of the big port engines I use in nitro r/c cars have around 3 hp.

 

This one absolutely blew me away:

Made a model of the Naper Deltic engine, which was a 18-cyl, valveless, opposing-piston, 2-stroke Diesel and originally designed for marine and locomotive applications.

I've looked at the animations available and I still don't understand how it works. There must have been a roomful of guys with great big throbbing brains to figure that one out!!

 

You will understand it in the near future.

Here's a clue....it's a 2 cycle engine, and uses port induction. Just like the 2 stroke engines of old.

They'll be coming into mass production within the next couple of years. These engines are modular in design, and can be modified to "turn off/on and disengage" cylinders to improve fuel economy, as needed.

There was a recent article in Popular Mechanics regarding the full scale version of this engine. And it's practical uses.

 

I love these desktop engines. I think I'm going to try to do one myself one day.
