Mini Stirling Engine - MAX RPM (Blow-Up Attempt #1)

In this episode, I push this little mini Stirling engine to the extreme and run it as fast as it can possibly go by applying as much heat as possible to the hot side of the engine.
After achieving a whopping 4,000 RPM, I then proceeded to dismantle and take apart the entire engine so we can look at the parts and how it's built and how it's made.
I was very impressed with the build quality and the overall functionality of this mini engine, I haven't seen anything better than this mini Stirling engine for the price.

Horsepower is just the engine torque multiplied by the rotational speed, then divided by a constant.

The reason Stirling engines are not in our cars today is because they invented the internal combustion engine. Which had faster startup and better throttle response.

On the other hand some military submarines use these engines , and they are said to be much quieter than a nuclear powered. sub. Only down side is they would need more frequent refueling compared to the nuclear fuels rods lasting many years. But would be much safer with out all the radiation.

I, and a couple other folks, have wondered about power output. It's real easy to get some results with the built-in dyno. Just wire up that belt-drive "motor" with a proper-sized resistor and measure the current. Volts, Amps, Watts!...use an electric model plane Wattmeter that reads out all three. One horsepower equals 745 Watts...use Watts for bigger-looking numbers! One could even set up another brushed motor running off that onboard generator with a fan to move air through an air/water intercooler that would pull heat off the "cold side" of the motor and make for a higher temperature differential. Make sure that the water in the intercooler thermo-siphons like a Ford Model T cooling system so no pump is needed...put the intercooler higher than the heat source with no dips in the lines. Use model plane silicone fuel line for water lines to intercooler. I like the liquid Nitrogen idea also. You could do "dyno runs" stock, stock with intercooling, and stock with nitrogen cooling. THEN you could do runs stock with MAPP gas. Mapp gas with intercooling, and finally MAPP gas with Nitrogen cooling. Maybe reverse the order of the MAPP gas runs so that the damage to hot side happens on the last run. (stock) For stock runs, just pinch off water flow to intercooler. Compare Wattage on all runs for a full test set!

[@BlueFangbluser]

Me: I wonder how heat powers those pistons How this engine actually works is it turns heat into rotation Me: thanks!

[@useless54868]

The engine works by a temperature difference on either side of the bottom piston. When the temperature on one side heats up it increases pressure on that side. It then has nowhere to go, and it pushes the piston backward. The flywheel stores that energy (kind of like a kenetic battery), and it transfers some to the top piston that pushes cooler air back down (the glass cylinder on top is at room temperature). Since this cooler air is forced back into the chamber on the cool side the difference in temperature is maintained. The flywheel also pushes the bottom piston back, and the hot air (on the hot side) forces it back down the tube to the flywheel. The top speed is reached when the two forces start to equal it out (The flywheel cannot store anymore extra energy). That covers the heat portion. Now for the mechanical side of things where the energy is turned into rotational. The piston has a rod attached to to bottom of it on a swivel. That rod connects to a round wheel near the outer edge on another swivel point (think crank on a boat trailer). As the rod pushes (strait force) this causes an imbalance of forces on either side of this wheel, so the rod pushes that side of the wheel. The bottom side of the wheel is still part of it so it moves in the opposite direction as the force is equalized (distributed equally across the wheel). This creates a turning motion A.K.A rotation. This is oversimplified, but I hope it helps.

You can get more power and RPM out of it by using a can of freezer spray on the other cylinder and piston at the same time as using the blow torch on the hot cylinder and piston. The bigger the temperature difference between the two is the key. Thats assuming the freezer spray is not flamable. Love the videos

[@Meatball2022]

The model is a real work of art. Side note - one of the reasons this type of engine didn’t make it is difficulty in controlling speed and throttle. Takes a while to get going. Not good for a car. Maybe more suitable for a home generator or similar. It’s kind of like a flywheel in that regard.

With the extremely rapid reciprocation of the piston, and the additional friction heat that likely created, I'm not at all surprised that it deformed. I am still surprised that the cylinder didn't, however... Regardless, I found this educational, and highly entertaining.

[@WarpedYT]

Yes same here! I am also surprised! Seems like it's made with the same material too!. Probably has something to do with the hot gas flow path through the cylinder, pulling the heat away from the cylinder around the piston and into the heatsink oh, that's my guess.

[@HasnainKhan-qn2nf]

I really don’t understand how the heck this engine works

[@Not_creativeexe]

iWantSomeBuns 69 hot air expands and pushes the piston down and you the cold air pulls the top piston down and it’s just a cycle back and forth until there’s no hot air on the hot piston

[@DFX2KX]

basically: Air on the hot side (where the candle/torch is) wants to expand, so it does so, pushing the main piston down. that main piston isn't quite as big as the cylinder, so some air slip around. That air is pulled up into that second cylinder to cool off (the one on the top), once this cooled air is pushed back down, it moves back past the piston to the hot side, rinse and repeat. There's a 90 degree delay built into the engine to give the air some time to move. The colder the cold side gets, the more air it can pull in and cool, and the more air will be able to go back and expand in the hot side. Therefore, the greater the difference in temperature, the greater the RPM.

[@nashvilleoutlaw]

Stirling engines give me all kinds of ideas on how to make them work more efficient and in a car. There are all kinds of modern technology that could be used like ceramic coatings to insulate hot and cold sides even metal gaskets themselves could be coated. Metallurgy has improved so you could run a thin low tension gapless piston ring now. Stirlings are more suited for constant RPM so in a vehicle it would probably be best to maintain RPM to drive something like a generator for an electric motor. It needs to be powered by something so why not the exhaust of a little 5hp engine that could power accessories like the alternator, powersteering, waterpump, air compressor to charge the crank case. If you made the top of a Stirling into an old style catalytic converter (new style is a blow through) it would hold the exhaust heat on the Stirling head. Or possibly make it a flat pancake converter that goes around the base of the heated head so heat would rise into an insulated chamber and trapped to heat the upper cylinder. I need to stop thinking....
