As a licensed Electrical Engineer I approve this video!! Well done sir, most people don't know how much knowledge and skill it takes to construct something like that. Congratulations!
@@dgphi Technically impossible. The only thing that sorta makes it a 4 stroke is it has four "pistons". It isn't using fuel, so every stroke is a power stroke. This would actually be a one stroke engine. The only force pushing the "piston" down is the magnet drawing in another one. The powerstroke pulls the "piston" in versus a fuel engine where the power pushes a piston down.
I designed one of these over 20 yrs ago. Called it the Pulse engine just using magnetic pulses to move pistons that turn a crankshaft. I'm glad its finally been done and sad I wasn't able to get the idea to catch on
Something he did that is very important: When he drilled the first hole in this video, notice that the drill bit did not turn. Only the brass piece turned, with drill bit remaining still. That is the best way to ensure the hole is drilled perfectly in the center. As long as the drill bit doesn't wobble, the hole will be in the center every time. Great video. Very cool design.
i think it is to complex and expensive in comparison to EM, a lot more moving parts, much larger in size for same power and it needs lubricaton for moving parts wich adds additional complexity, and also you would put giant magnets in metal cars... maybe not so good idea....
Amazing build! Just one correction: stroke is not a zylinder(piston). You had built 1 piston then 4 piston engines. Both of your engines are 2 stroke. A stroke is one complete linear move of a piston
The Practical Engineer yes sir. Two stroke would be more often found on dirt bikes (sound real raspy) and four strokes in more street vehicles. Four strokes go down and up twice to complete one full combustion sequence. While two stroke do it in to. Exhaust gassed leave slightly after combustion occurred, and early on the compression stroke, mixed air would flow in.
You should have made some conclusions. About how efficient the motor is. Measure the power. Compare efficiency to a brushed engine. And try to find a way to make it more efficient.
Nice shop and build. Greater complexity adds greater "wow factor" ..consider a few modifications for your next build. Use "shorter" length journals and PRESS the journals into the crank counterweights (correctly timed) and PRESS the crank end shafts into the outer counterweights, ..this will shorten and stiffen the crankshaft. Cut a flywheel for the back of the crank with four small holes, then press in four small Neodymium disc magnets (correctly timed). Make a timing plate with an alignment pin to the center of the flywheel and attach to the wooden base. Cut a circular/rotatable mount that indexes on the pin, the mount will hold four Hall effect sensors (adjust the timing of the mount and lock with a screw) ..the Hall sensors will trigger the FET's and coils.
Wow! Amazing video and i can see the amount of time and effort you’ve put in building that solenoid engine and also in editing the video! Loved it! Keep up the great work!💯
@@Thepracticalengineer More precise tolerances and actual press fit instead of lock tite fit would have helped you. Or the actual best would have been machining a one piece crank shaft.
@@Steve211Ucdhihifvshi what are all the things that make it less efficient than a motor (having a similar power draw)? I'm making a reciprocating saw inspired by this video. So any ideas would be appreciated.
Like your directing style and that you show f-ups! I am subbed. Cool project too btw - I'm kind of fascinated by electro-magnetics and you inspire me to do some messing about with them. Cheers. What kind of mechanical power does that engine produce?
Mr. Practical engineer. If you could design and engine that would be a V-twin same size as a Harley that would affix to the existing transmissions inside of frame of the motorcycle it would be wonderful...!
Simply Amazing. I studied 4 years to be a machinist myself. I appreciate all the work you've done. Do you have any idea of the horsepower rating put out to that engine design versus conventional electric motors. I would love to know the answer. Thanks
What a cool crankshaft. Will the Conrod’s wear out quickly? I know it’s small but just wondered if you need to lube it or make mag shell bearings which it looks like you have the ability to easily do. I love little projects like this. I just don’t have the tooling.
Firstly, I have had a very similar machine in my mind for years and years but I've never had the resources available to make one myself, so thank you for the work and video. Secondly, it seems you are using DC as a power source, and using physical movement to create the timed switching of the applied power. Which is a pretty neat idea. I wonder, though, why you wouldn't drive the system with AC. Then you could use some capacitors to offset the timing. Then in theory you could adjust the freq of the AC source and change the engine's output rotation speed. Thirdly, I feel like you you could generate stronger forward movement on your solenoid if you made the piston driven by electromagnetism coupled with a strong neodymium magnet on the base (think speaker coils). Loved the vid, I'll subscribe to see this develop further. It would be cool to see a E-V8 engine. If tuned efficiently I wonder how it compares to the conventional electrical motor. In theory such an engine should be able to produce gob loads more torque at super low RPMs.
Nice work i suggest you put this engine in a flying aircraft or helicopter then use a circuit with arduino to control speed .that would make it cooler i doubt this engine power would be able to handle the lifting of aircraft body
@@ezza88ster yes I agree it is a magnetic field MOVING in a coil at a RIGHT angle..but, the way its setup is a solenoid (coil that gets energized to create magnetic field to push or pull the ferrite/permeable core in and out..if you tried to make it in reverse with the core as a magnet going in and out of the coil then yes, you might generate a smidge of power..then again where is the rotation coming from to push/move the magnet core in and out of the solenoid? So if you wanted to make it a generator, you could with great losses because you'd have to drive it externally. Whether it be a drill or good old hand power. Either way its a fun thought but not practical. Cheers
Maybe people will be more comfortable driving an 8 cylinder Silinoid electric engine???? Just an idea, you might want to consider making a full-scale engine version of this and see if it works. :)

As someone without a high-school education, I can honestly say it doesn't take much.
Very well done however this wouldn't represent a four stroke engine, rather a (2 stroke) four cylinder engine. Thanks for the video.
Thanks for the heads up. I realized the same after recording
It would be interesting to modify it to be 4 stroke and see how well it runs.
@@daspedal2730 the title says it
theBenski27 he calls it a 4 stroke in the first 15 seconds of the video.

Darnit.
Even the most impractical ideas have allready been made into reality before I came to them.
Impracticality is endless
Could you actually power a car with a scaled up solenoid engine?
In some way yes. But I don't think it will be very powerful or efficient
Yeh not very powerful
yea sure you can. It would be just for fun though as its not efficent.
You could make a aci fi looking hypercar though with a v12 solenoid engine.
The Practical Engineer what do you think about trying? Do you think with testing and research that you could make an effective solenoid engine?
i think it is to complex and expensive in comparison to EM, a lot more moving parts, much larger in size for same power and it needs lubricaton for moving parts wich adds additional complexity, and also you would put giant magnets in metal cars... maybe not so good idea....

How am i gonna measure that
By measuring the RPM, the torque, the power consumption, maintenance, and the cost either in the long or short term
Inefficient as hell :D
Well, what you saw at the end was a motor running at 0% efficiency.
You do that lazyass lol

The next logical step would be to make a working solenoid radial engine
lol
Its on my list
Yes we have them .it's called electric motor Lol
Or a W18.

Cool. The same mechanism some of the door bells and school bells used

BRILLIANT, BIG ROUND OF CLAWS FOR YOU AND FOR YOUR PROJECT👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
It looks and sounds great but the alignment just wasn't there, so many wiggling parts which increase your friction and affect the inertia :(
nope, it was hard to get the crankshaft all perfectly aligned this way

I mean technically it’s an electric engine that sounds... good?!
LOL yeah if I ever get an electric car I want one that makes vroom vroom noises xD
Its cool but, apart from making a noise its no where near as efficient or powerful as an electric motor.
@@Steve211Ucdhihifvshi Efficiency wasn't the point though.
And has shitty efficiency as a consequence. There is a reason why it is not done this way.

If you wrap two stands around the solenoid core you get same number of windings with less resistance

Waarom zou je 4 lineaire motors bouwen om 1 as te laten draaien?
Omdat het mega tof is!

if you wanted a flywheel for mass why did you drill out a bunch of holes, reducing it's mass?

Electrical motors don't need the inefficient design that is necessary with petrol engines.
When you consider the waste of producing that power and distributing it, the picture changes drastically
Fantastic to watch, nice video!
I haven’t seen anyone with so many tools before
holy shit dude. I learned how to make an offset cam today! awesome.
That engine is so cool!!!
Please build a tool you can use to hold and reposition things you are sawing so you don't saw your fingers off. :)
Nice work i suggest you put this engine in a flying aircraft or helicopter then use a circuit with arduino to control speed .that would make it cooler i doubt this engine power would be able to handle the lifting of aircraft body
It's a heavy thing though
The copper wire alone is almost 500 gram
...or you use an electric motor and all the “cylinders” are poles with no pistons needed!
that's boring!
Someone probably mentioned this, but what about running it backwards as a generator? Great video btw.
Rethink your sentence and repost..hint "solenoid"
The rod would have to be a permanent magnet I think.
@@ezza88ster I see your line of thinking, however..what pushes/pulls the now-permanent magnetic rod?

YOU SHOULD MAKE A CROSS PLANE VERSION !
Are not magnetic cores more powerful and efficient ??
I dont understand why he uses the 4 transistors. Wouldnt it run with only the 4 mechanical switches?
Maybe people will be more comfortable driving an 8 cylinder Silinoid electric engine???? Just an idea, you might want to consider making a full-scale engine version of this and see if it works. :)
Can you do this large scale? How much power will this give you?
Ok so next question, what is the theoretical maximum amount of solenoids you could add before you stop getting an increase in performance
very good project
A 4 Jaw chuck and machining the crankshaft in one piece would be better.
You should use a live center :)
Amazing work broo
What is power of the engine, did you measure?
I didn't see you counting turns so I'm curious to know if you calculated the amount of flux for each coil, or just generalized.
Can I get a print out of how to make one please
Should try to do this to scale on a v8 gas engine to convert to electric?
Just WOW man! Amazing!
Thanks!
When the time comes that I have to get an EV, I want this guy to build the motor.
Keep in mind, a real electric engine have one moving part
You really want an EV with all the cons from a fossil car, such as moving parts that wears down, frequent service intervals, and oil changes?
What's the speed at which it's rotating ???
Great job 👍
what does the sliding contact do?!!
is this power full than a motor?
Awesome video
Try powering something with this
Excellent upgrade on the one cylinder (solenoid) engine. Now I want to see a V8 version.
Also have you got any way of measuring the torque produced?
I did not measure the torque. But it is not a whole lot
where can i get the circuit diagram for the engine
01:06 very emotional moment
has rod knock, needa get that engine rebuilt
Very cool video!
Can u make it full size?
is this method efficient?
I wonder if this would be a good generator? Or maybe a very overcomplicated electric motor?
I doubt that this could create electricity, as there are no moving magnets.
How do u get the timing right tho?
I wish I had learnt this at school.
WHAT IF YOU ADD A MAGNET GENERATOR?
Best Engine!
How efficient is this related to the normal EV engine car?
far less
but it looks like it was fun to build 😊
Can bigger version of this run a three whelled kart????
I haven't managed yet to make it more powerful in this scale
