Ben, there's a ton of good content on this site... what are you talking about! Support people like The Practical Engineer, there are so many others too.
Even with a component fastened down, a sharp drill bit can ‘grab’ . We were always taught to back off the drill cutting edges. We did drill many brass components in a manufacturing company and it worked well.
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....
Use neodymium magnets as the pistons. Make the magnets slide on nylon rings either end of the magnets to minimize friction as they slide in and out of the coil pack. Use both push and pull cycles on each cylinder (invert polarity to push the magnet back down). A better winding design will give a stronger magnetic field when charged. The engine layout (inline 4, V-4, Radial 4 etc) doesn't matter at all if the crankshaft is right.
I love this guy. He ain't afraid to poke a little fun at himself. Broken bits, unexpected collisions. Leaves them in to give us a bit of a chuckle while we watch a very interesting build. Great stuff!
There is a video called "electric motor secrets" I believe you can really appreciate. In the video the presenter mentions the potential of a solenoid engine has been overlooked and presents qualities that aren't found in most electric motors.
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.

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.
I like how he shows everything in extreme detail and takes time to explain each process. With the exception of the quick snapshot of the wiring on the bottom side where he was installing transistors.
When I was in the navy I worked in the machine shop of a submarine tender. We had a crankshaft lathe for making crankshafts from scratch out of a solid piece of forged steel as well as a crank grinding lathe. I was one of the lucky ones to be trained on that equipment. We also had a cam grinding machine with hundreds of patterns.
IT would be interesting to measure the power output of the engine and perhaps work on an improved variant. I feel that making more precise switches would help a lot in terms of speed and stability.
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.
Great vids. Great projects. The ideas are the hardest bit. Note:- Center drills are commonly used in engineering, center pops are not used to position the drill. Get some center drills, no 1 is too small, no 2 or 3 will suit you.
Not saying that you're wrong but it's entirely possible to be very good at one thing (designing and building things from metal) and bad at another (vocabulary). I've personally worked for someone with a PhD who didn't know how to change a light bulb.
V4 is the cyclinder arrangement/orientation - one could have flat-4 as in the VolksWagen Variant 1600 from the '70s where the pistons were diametrically opposed.
Robert Lawrence yes. Obviously not an actual firing event, that’s why I put it in quotes, but for the sake of balance, you’ll want to have opposing solenoids “firing” so there is, in fact, and order that should be used.
I have been a machinist for over 50 years. A tip when drilling brass and copper is to grind a zero degree rake on the cutting edge of the drill. It won't grab then. just take the sharp edge off it. It may take a little longer, but, you won't break drills and it won't grab the material.
You must be joking but if you are not, no that is not the electrical motors they put on teslas. This type of electric motor is used in no car, afaik is not used anywhere, is just a proof of concept (to show that you can make a piston based electric motor) but afaik is very inefficient and not powerful enough, compared to normal (no pistons only a shaft) DC/AC electric motors and piston based combustion engines.
If the rods were to be magnetic, the timing on each contact had to be pretty precise to avoid the magnets dragging and subtracting from the momentum. But, it would work, and this could be converted into a generator, just like most DC motors can.
Sterby jr. the rods are not magnets. They are simply metal rods, that become affected by the electromagnetic force created by the coil when the power is turned on. The force created is much stronger than a permanent magnet. But a magnet passing through the coil will induce a current to flow in the copper wire.
Thank you for building this. I had the same idea in the late 80s. I of coarse had no tools and no skill so it never got done. I love being able to see it actual could have worked.
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

I've thought about this idea myself but lack the tools to make it happen. My idea was to make pistons of permanent magnets on the tops and electromagnets attracting and repelling the magnets to make the drive. You could enclose the chambers like a real piston to provide some compression and spring for the return motion after the pull.
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.

You could have variable "valve" timing by using non-offset flywheels for the contacts, and instead covering a portion of the contact with masking tape. Then you could experiment with different timings.

Basically he aligned the crankshaft farthest reach of the rod and offset it by little clockwise as timing where the coil will turn on to pull the rod.

Two stroke engines have one power stroke for every two. This electrical four piston motor is a single stroke affair since there is a power stroke on every stroke. The electromagnetic field, I believe pushes and pulls that rod as it switches polarity.
@@vripiatbuzoi9188 at 14:25 it sounds to me like he means it's an on/off contact, not a reversal of polarity.
@@gimmeanicecream9228 Then what brings the piston back? I see no spring and when he was testing the coil without it being tied to the crank shaft it was going back and forth on its own.
@@vripiatbuzoi9188 I don't think I was paying attention to that part at the first viewing!
It does seem to 'bounce' when he flicks the switch on and off, but centres itself when he holds the switch closed. It doesn't show what happens when he lets go of the switch after it has centred?
This isnt a pencil sharpener?!
Why am I even here?
Lol it would make a great science class pencil sharpener!!
You could have variable "valve" timing by using non-offset flywheels for the contacts, and instead covering a portion of the contact with masking tape. Then you could experiment with different timings.
All of your tools sound sick.
