When you think that air can be compressed and liquified, than a tank can hold large volume and reserve for long distance funny trips in the garden. Really cool !
Thanks it’s been in the making for quite some time. I originally built that some 10 years ago probably by now over the years looking back finding better ways to do the same thing I did things I want to make it better thanks for checking in. I’ll be posting more things soon.
This is so awesome. Compressed air doesnt hold too much energy though, perhaps a regulated system to decompose peroxide for a steady pressure supply? It'd be closer to a steam engine at that point.
Sweet! Nothing wrong with any of this, so long as you bear in mind the inherent inefficiency of compressing the air in the first place. If you have hydro or wind or even a natural gas well, then you're all set.
FYI look at the steam tripple expanson engine..three times the engine uses one original input, each one reduces the out put for the next piston, after the last third piston cycles the output..good effort..
thanks for your thoughts, and I am sure in some applications it might be worth the complications and extra parts, but it just doesn't fit into my simple air engine.
Awesome! This runs pretty smooth and I love the way it sounds. Congrats. So close to 1000 subscribers too, can't wait to see that milestone as well. Keep it going, thanks for sharing your project.
I love seeing you pulling your buddy around on the tractor.. with the low gear ratio you have an opportunity to show off the torque by pulling heavy objects and climbing steep hills. I found when I added the use of a transmission on my second prototype it multiplied the top speed more than four times. So I would suggest looking into putting some changeable gears. I agree that you need larger cylinders, but it's lower pressure that will get you where you want to go. Higher pressure is just blowing out your exhaust and the efficiency of energy conversion goes with it.. do the math a 1" piston at 150 psi is going to push about the same as a 3" at 20 psi.. if you calculate potential expansion in the cylinder, using advanced intake cuttoff, you will find its not hard to use 100% of 20 psi for force, leaving nothing to waste.. it's at about half the stroke.. your timing advancements over 150 psi would have to be at nearly the top of the stroke to use the force effectively.. stop wasting your time by ignoring my advice.. let's show the world this can be done
@thedubwhisperer2157 at 15 psi my efficiency of expansion to mechanical force is roughly 100%, so subtract the resistance of two double action cylinders and a rotary sequence valve, and there's your answer. I just wish I had the luxury of time and funds to continue my research right now, because I am ready to begin producing air powered bikes and am moving on to developing liquid nitrogen transportation. The cost of living combined with projects like replacing my roof has me financially overwhelmed and it might take a bit for me to be able to catch up.
Happy to see you still working on your Engine. We got hit hard in the County here in Upper east Tennessee by that tropical storm. Lives,homes,roads,Etc. Still saying weeks for power,phone,Etc. to get to some people here. The first week we were cut off due to trees and washed out roads. Have you thought about using a three cylinder engine and adapt it to run on Air ? Or use those pistons out of an oil less Air compressor has they are fairly cheap on ebay / amazon. ? As always I liked and shared. All my very best.
Years ago, I started with a crankshaft, but I found that it uses twice as much air because the piston moves twice as far as any of the designs that I’ve used so I basically have to make everything. In my six cylinder engine, the pistons are free floating. They only move up and down when Air is turned on otherwise the engine just free wheels. I feel for all the places that have been hit by these horrible storms, and looks like the future is gonna continue having them. Thanks again for your comments
Very cool design. It would seem that a slightly longer stroke and possibly steam would be benificial for more power. Steam would give more expansion than air.
Thanks for the comment, and yes steam would work but not practical on my small homemade vehicle, boiler, fire box , something to burn and water - now I just need an air tank,
next step is to change the gear ratio, you might have enough power and rpm to go 3 times faster . think of a car in first gear , you can get the rpm up to 5k but only going 25 miles per hour but the motor has enough power to bring the car to 80 or 90 it just needs a different gear . i wouldnt change the pistons or any thing else untill you gear it to the point where it doesnt have enough power to push in that gear
I hear you and agree with one gear it has to do all, Flat ground, downhill and most of all back up the hill. I will be doing much more trial drives to be sure I can get max out of it. This winter I think I will do some modifications on it to get the valve system on top instead of under the bottom plate. It is not timed the best right now, it's hard to get to them where they are now. For now, I need to work with my design to get a safe flow/pressure regulator working before I can do more with my main engine, the 6 Cylinder for the VW.
Thanks for checking in, and if it’s the six cylinder you’re talking about, there are two metal plates internally that are basically flywheel. If by chance it’s the three cylinder, there is the oval ring that rotates as a fly wheel, so there’s no need for any additional five wheels. I haven’t really had a chance to test with the six cylinder, the first time I put it in there was problems with the seals in the valves, which I have taken care of by going to all metal internal parts. Before I can do anything further with either engine, I need to develop a pressure flow regulator to control the air pressure and flow to the engine.
I subbed because i think you deserve to be over 1k subs. Like a power washer nozzle increases the pressure forcing through a smaller orafice. Can you use that line of thinking to increase the pressure applied with the same psi in tank.
Thanks for the suggestion. I believe it does increase the pressure per square inch, but it is a much small area coming through the orifice, but once it is through it expands to the volume of my cylinder and has much less force. I am basing my design on how many cubic inches of compressed air I have, the Nr of Cylinders, the Square Inches in each Cylinder, and the number of engine revolutions to tire revolutions. There are a lot of complicated formulas that can be used, but it still comes down to how much compressed air I can carry and how far it will take me.
I think that's one of the secrets to along and healthy life.Keep the mind working.
When you think that air can be compressed and liquified, than a tank can hold large volume and reserve for long distance funny trips in the garden. Really cool !
That’s the coolest engine I’ve seen in quite a while !

Awesome stuff keep it up!
that is a great achievement that it is balanced and machined the way you designed it i respect you highly and thanks for sharing..
Great to see somebody go from a prototype to a working model. So many videos are concept only or only take you so far. Nice work
Sorry to say it’s still a prototype, even though it ran, there’s still things that need to be changed
Thanks for your response though
Cool engine congrats
Very cool!! Me and my dad used to talk about making one of these. Pretty cool to actually see one.
FYI look at the steam tripple expanson engine..three times the engine uses one original input, each one reduces the out put for the next piston, after the last third piston cycles the output..good effort..

WOW that is the coolest engine allmost sounds like a Harley Davidson idling.🤠
Awesome! This runs pretty smooth and I love the way it sounds. Congrats. So close to 1000 subscribers too, can't wait to see that milestone as well. Keep it going, thanks for sharing your project.
Thank you very much!
Awesome job
I hope I'm as sharp as you when I get time to do the things I want to do.
If you’re determined, that is I think the best way to hopefully be that way!
Keeping your mind busy and don’t give up
Don’t wait. Do things now. The future will not look like you think it will.
A year of research can save a day at the library.

"blowing out your exhaust and the efficiency of energy conversion goes with it..."
What is your current peak efficiency of conversion?
@thedubwhisperer2157 at 15 psi my efficiency of expansion to mechanical force is roughly 100%, so subtract the resistance of two double action cylinders and a rotary sequence valve, and there's your answer.

That can be something looked at later right now. I’m just trying to design and develop the mechanics of it.

Thanks again for your comments
I think you recorded major Steps for the day on your watch. 😂
I know safety is last, but you should shield yourself from the exposed engine sitting behind you. They call it a head ache rack for a reason.
Very cool design. It would seem that a slightly longer stroke and possibly steam would be benificial for more power. Steam would give more expansion than air.
Thanks for the comment, and yes steam would work but not practical on my small homemade vehicle, boiler, fire box , something to burn and water - now I just need an air tank,
Do my timing with photo interrupters,plenty of adjustment ,instant operation and no balance problems!
The sound reminds me of the FORD Model T
It’s a bit louder than it sounds in the video
next step is to change the gear ratio, you might have enough power and rpm to go 3 times faster . think of a car in first gear , you can get the rpm up to 5k but only going 25 miles per hour but the motor has enough power to bring the car to 80 or 90 it just needs a different gear . i wouldnt change the pistons or any thing else untill you gear it to the point where it doesnt have enough power to push in that gear

That engine in a lightweight T-Molding type chassis with motorcycle wheels has to reach 80 km or exceed speed
Thanks for responding, but I’m not quite sure what you’re saying in this comment?
Any chance a flywheel would help improve it?
Thanks for checking in, and if it’s the six cylinder you’re talking about, there are two metal plates internally that are basically flywheel. If by chance it’s the three cylinder, there is the oval ring that rotates as a fly wheel, so there’s no need for any additional five wheels.

Before I can do anything further with either engine, I need to develop a pressure flow regulator to control the air pressure and flow to the engine.
Is there a practical application for this or is this just something you are playing with?
Looks like a play toy at this stage. Compressed air has been around a long time! Very little unplowed ground left!
1000K
Thats nifty
I subbed because i think you deserve to be over 1k subs.
Like a power washer nozzle increases the pressure forcing through a smaller orafice. Can you use that line of thinking to increase the pressure applied with the same psi in tank.

You are waisting your time, calling it a six cylinder" engine shows that your ideas about mechanics are wrong from the het go
