Unique 2-stroke model engine: 2-stroke combustion process on both sides of a single graphite piston in a glass cylinder. Design Jan Ridders; The Netherlands
This is pure genius. If you put a magnet on the opposite side of the flywheel and surround it with a copper coil it would be able to generate electricity. Smooth it out with diodes and you would have a DC power supply. Of course a dc motor on the flywheel side would also generate electricity. Thanks @Jan Ridders I will try do build a machine based on your design. If you don't mind.
I built a shuttle piston steam engine with a shuttle sleeve valve back in 1983 as an apprentice piece (which the damned college kept as a demonstrator!!). It had articulated conrods with adjustment screws for fine tuning the stroke for maximum torque. It was self starting and had a speed range of 40 to 80 RPM with a lot of torque, possibly enough to power a bicycle or skate board (in my mind at the time if I'd been allowed to keep it). I did enjoy making it at the time. Possibly a 4 stroke shuttle piston version of this 2 stroke shuttle piston motor could be built using the same shuttle sleeve valve principle either driven off of the flywheel (how I designed my steam engine) or actuated by distributer slider action.

The channel “Project farm" did a video comparing the difference in fuel consumption between vaporized and carbureted gas and the conclusion was that there is no difference. Both runs on the engine ended roughly the same time with the same amount of fuel.
Mr. Ridders, I would love to see you make a small piston air pump that would run off the crankshaft to feed the engine the proper fuel mix needed to make the engine run on its own, I love this engine, would love to build a multi cylinder version of this myself one day! you never fail to inspire me!
I tried to make such a air pump but that is not that easy in this case because the pum must be rather big or it must have very high speed to deliver the required amount of air.
Jan Ridders I was thinking last night, what If you had a larger fuel tank that you could pressurize with compressed air before starting the engine then have a pump to try and maintain the tank pressure? but yes you do raise an interesting point, I do wonder how much power it would take away from the engine?
Jan Ridders I'm a bit late to the conversation, but you could always capture that power from the exhaust phase with a turbo charger... It might be an interesting project to machine as well. Otherwise there are always brand new 1.8l Audi turbos for roughly 100$ online. Either way it shouldn't take any power from the crank so long as it can produce more air pressure than the fish pump.
Good job Jan. It would be neat to see if you could replace the aquarium pump with a small mechanical driven pump and then it would be self sustaining. It would need to be able to pump fuel vapors. Also might need to be spun up faster than hand starting to get the vapors moving but once it was running it might keep going. That is if the motor has enough extra power to spin the pump??? Very neat the way it is. Cheers Willy
When it starts firing, first cylinder fires compressing the gases on the other side. That side ignites and compresses the other side and so on. Just like a regular 2-stroke but the compression stroke is done not by momentum but by ignition on the opposite side.
Well, Mr Ridders did a similar design, but it was a one-cylinder model, compression was achieved by a weight pushing the piston down. So I think it might be possible with an explosion instead of the weight as well. Of course it looks much much nicer with a flywheel and also runs much more nicely for shure.
It sounds like an old fashion hit and miss engine. The spark flash (ignition) at either end of the glass cylinder seems erratic . My guess is that it is caused by uneven charges of the air/fuel mixture. It would seem that the glass cylinder used for the fuel tank (evaporation) and the tubing used for air intake would not have sufficient control of the A/F mixture without some sort of pressurized metering devise which would assure a load of 15 to1 air to fuel ration to the combustion chambers at either end of the glass cylinder being used as the crankcase ?? Poor A/F mixture to a conventional four stroke engine is often the cause of rough idle and loss of power at higher RPM. Clever and simple devise, great video.
I didnot consider to make a 4-stroke version of this because making a distribution system for both cylinder sides with intake and exhaust valves would be very complex. This engine runs for 15 to 20 minutes on one tank filling. Friendly greetings from Holland, Jan Ridders
So... Can this thing be considered as a 1 stroke engine? Because on a 4 stroke a combustion occur every 2 revolution (4 stroke of the piston), on a 2 stroke a combustion occur every 1 revolution (2 stroke of the piston) while this has combustion occuring at every half a revolution (every 1 stroke of the piston has combustion)
It would be nice to see a small load placed on these small engines. Something like a fan, or a alternator with a volt meter. Also, how much load it would take to stall the engine. Great work by the way!!
Just some advice but tell me what you think! so i counted 2 magnets to power a coil for spark but if you played around with 4 magnets you can keep them in set of 2 on both sides of the flywheel so that you can remove the distributor arm and have more of a solid state sparking system, if you want i can email you a very simple diagram that shows you how you can use 1 coil for both cycles or 2 coils for the individual cycle but pro's and con's 1 coil would be nice for overall size and might look a bit nicer than 2 coil's con's of just one coil is that it will work twice as hard. either way, by removing the arm you can get better response time and might be able to attach a pneumatic piston to it that can fill a small air tank to supply air for the carburetor the only reason for the tank is that you can control the pressure of the tank to get a better flow of air to the carby which will give you more control over rpm
as a side note, the "air pump" can be designed the same way your engine works with a single stroke so you can use 4 valves , 2 on each side of the air chamber so that as it pushes air into the tank it also fills the opposite side of the air chamber. that way you don't have to make a chunky piston because you half the piston size while getting the same result as you would from a chunky one

That's really cute like a double acting steam engine design used in a 2 stroke ICE I love it when people find new ways for old technology.

That’s brilliant. I bet it runs for hours using the vaporising carb method!
The channel “Project farm" did a video comparing the difference in fuel consumption between vaporized and carbureted gas and the conclusion was that there is no difference.
Both runs on the engine ended roughly the same time with the same amount of fuel.
Fantastic Jan! Another working example of inventiveness!

I'm so curious on how the valve timing works. Amazing engine, and looks like very efficient too.

Sounds great.Could listen all day
Beautifully done! Maybe add an arm so you can advance the timing?
Yes that's the function of the air pump here.

it looks working at very low RPM and power
Jan Ridders your puppy 2 stroke is for sale??
Thanks for your positive reaction and compliment.
Greetings from Holland,
Jan Ridders
Do you have the plans for this? I’m fascinated and winter is coming in Wisconsin would be a great downstairs project thanks and hi from Wisconsin
Would you consider selling this? Or at least the plans/part list? I have access to the equipment to make this.
Can you make a video on how you made that piston
So... Can this thing be considered as a 1 stroke engine? Because on a 4 stroke a combustion occur every 2 revolution (4 stroke of the piston), on a 2 stroke a combustion occur every 1 revolution (2 stroke of the piston) while this has combustion occuring at every half a revolution (every 1 stroke of the piston has combustion)

Great work by the way!!
Not much i presume , id imagine it could barely power a sewing maching
very good ... put similar flywheel òn other side so both strokes will be balance and efficiency will increases..... all the best
This should make for a powerful engine!
I love your projects, I wish I could make something like that
Sehr interessantes Teil. Verkaufst Du eigentlich auch?
Very nice engine - similar to a double-acting steam engine.
Would it work without the flywheel as well?
Best Wishes!
Greetings from Canada. Great work!
would love to see how you built that piston.
Its a graphite piston glued on brass rod i think
Just some advice but tell me what you think! so i counted 2 magnets to power a coil for spark but if you played around with 4 magnets you can keep them in set of 2 on both sides of the flywheel so that you can remove the distributor arm and have more of a solid state sparking system, if you want i can email you a very simple diagram that shows you how you can use 1 coil for both cycles or 2 coils for the individual cycle but pro's and con's 1 coil would be nice for overall size and might look a bit nicer than 2 coil's con's of just one coil is that it will work twice as hard. either way, by removing the arm you can get better response time and might be able to attach a pneumatic piston to it that can fill a small air tank to supply air for the carburetor the only reason for the tank is that you can control the pressure of the tank to get a better flow of air to the carby which will give you more control over rpm

Dutch are true engineers
Someone said they were run of the MILL!
What kind of glass did you use dor the combustion chamber?
Thanks for posting, Fantastic, even your drawing are superb. Which programme you use for the animation? Thanks again.
Alfred.
This has to have amazing power density, considering it has two power strokes per revolution... That's the same as a L4 4 stroke!
Wonderful! Please more videos
How do you provide oil with such a clean carburator?
Hallo Jan,
Gratulation, wieder ist Dir eine schöne Maschine gelungen. Der Motor erinnert mich ein wenig an den Lenoir Motor. Bedenken habe ich für das Kabel des Zündverteilers, das geht doch sicher Kontaktlos und erhöht den Wirkungsgrad.

A steam engine-esque design.
This would technically be considered a 1-stroke engine.
Amazing creative innovative .consider hho as a fuel source!
had you considered making a four stroke version of this? also how long does it run on a single tank of fuel?
How much power it has? I have theory in my mind about ornitoptheris from dune with moving wings power by this engine
amazing simple design ! Please try running on propane or butane or hydrogen !!!
Where can I purchase one of these
Clever design! :D
Jan Ridders bonjour,magnifique réalisation! en quoi est fait la chemise piston ?car je voudrais faire ce moteur.

That would be "one stroke" ?
I'm not sure, but it maybe it could be considered a "double acting 2 stroke"
@@oshkiv4684 nice but not a two stroke mixture works on both sides of piston and transfered via ports
Friction would be almost non existent with a glass cylinder. Also fuel by its nature is a lubricant and also disperses heat to some extent.
lovely genius
Very iteresting well done! Thanks for posting.
How would u do throttle.?
What are those piston made of?
wow
heb je hem nog?
Wouldn't that be a singe stroke or 1-stroke since it fires every stroke?
Johndeere 100 Not really, watch the slowed down segment, still a 2-stroke.
+Carson Sylvander how? It fires every time the piston makes a stroke thus a single stroke
silly question, where the air/fuel mixture comes from?
Another winner.
how intake valve get closed?
ДВС двойного действия!
Великолепно!
Excelent...very good..
How would that work?
I'll be ! Thats awsome 🙂👍
Uitstekend!
Isn't this single stroke engine?
Now make a V12 like this.
I fully support this genius idea.
We need to interest people in engineering
Just pressurize the fuel tank from the exhaust! We R/C fly Boys do it all the time to feed our nitro or gas engines !
Mike MacDonald why ?
@@tonywright8294 Depends on the carby! -- one type likes it the other doesnt need it but it helps!
how to make
За счёт чего у него продувка?
Алексей Комаров я тоже не понял в чем секрет продувки
amaazing!
Wow.
sounds great
Hey wat voor soort brandstof die ze gebruiken voor deze motor groet Andreas
Thod it was normal gasoline. Most of the time he oils the engines before every run. And the pistons of graphite if im correct don't need lubrication.
Muito lindo!
does no one realise this is a a 1 stroke engine?
Easy to convert into an electric generator.
1 stroke
Nicht schlecht...
Wrangkel Engine... must be copied how vapore gasoline burn... so exhaust not make pipe burning....
now do it 4 stroke
Make generator
Dont look very powerfall,.
i see ...the bouncing one
My first concept ws withou fly wheel indeed and it worked more or less but the behavor of the engine was very wild. See the concerning page on my web site "ridders dot nu"
