V8 Solenoid Engine

[@MichaelTheRead]

One of my favorite facts about life is that no matter what it's made out of, a V8 will always sound badass if you can get its parts spinning fast and steadily enough.

[@golferchin76]

Seriously man, if I was an elementary school kid and see this in a science fair I would have been blown away by the awesomeness ! Even as an adult this puts a smile on my face, great work.

[@produKtNZ]

I quite love your ingenius method for controlling the engine speed via contacts on a cam shaft. A very elegantly simple solution :)

[@HuntosDee]

I noticed that too but my knowledge of mechanics isn't great so I don't fully understand it. Would you mind explaining how this works when you have the spare time?

[@davidrobert2007]

David Hunt Above the camshaft you will see eight copper wire prongs, when these prongs receive electric current from the camshaft, the relevant solenoid switches on. Moving the copper prongs closer to the camshaft results in a longer duration of electrical contact, and therefore a longer magnetic pulse from each solenoid, and of course more RPM. I have a couple of single cylinder engines on my channel that use this principle if you want to see in more detail. I hope this helps.

[@HuntosDee]

Wow, that's genius! You explained exactly the part I didn't understand. Thanks!

[@VinnyMartello]

An electromagnetic V8. Now I've seen it all. Great work!

[@VinnyMartello]

@@scottcrawford7674 It's a great question. But this adds a lot of moving parts that a regular DC motor wouldn't otherwise have. In a daily driver situation you would most likely see reduced efficiently. It's entirely possible to make it work. But it would not be practical.

[@ggnutsc]

That is pretty cool!!! The cam operated firing for the solenoids is very similar to the older diesel engines with mechanical injection timing. You could use an encoder on the crankshaft to detect crankshaft position and a computer control to electronically fire the solenoids and it would be similar the newer style engine controls. Obviously without the valve train. Two thumbs up from a great build!!!

[@quadrunner2124]

One part of me thinks this thing is a beautiful work of art, and I'm thankful to see it. The other realizes that the builder obviously has the resources to utilize his time for something truly useful. Balance is key to a good life.

[@murilovsilva]

I would buy an electric car if its engine was like this one.

[@pokrec]

Such an engine would consume much more energy than normal electrical engine. Piston engines in case of internal combustion are necessity if we have to maximize the efficiency in automotive applications, but in case of electric motors, the rotary types are almost perfect and have primitive construction in comparison with solenoid / piston engines. If you lack the sound of V8 engine, you can always get come audio system to emit this sound for you via car stereo system. The more primitively constructed engine - the less maintenance and lower the price of purchase and later service. This is a nice toy, but I have never heard of anyone, who used a solenoid engine to any serious work (of, course, there are linear engines, but used in a very specific application, where the linera motion is expected and there is no need to convert the reciprocal motion to rotary motion. Such a conversion is always troublesome.

[@thesantiso]

Amazing, that size, solenoid and still sounds like a V8. Nothing beats that sound dude

[@davidrobert2007]

Ah, I thought so - It runs on straight 15v dc but when it's running the action of the cam lobes hitting the copper prongs provides pulses of current to switch the solenoids, the closer I move the prongs to the camshaft the longer the duty cycle, so it is effectively mechanical pwm, although the duty cycle cannot exceed 50% as the solenoids can only pull and not push. Hope this helps and thanks for your interest :)

[@cmwehrmann1]

I love cars. I love working on cars. Cars and anything engine driven are basically my life.

[@mspenrice]

In an alternate timeline, where we invented neither internal combustion nor rotor-based electric motors...

[@davidrobert2007]

The copper camshaft is energised full time and when a prong touches a cam lobe it switches a relay which then switches a solenoid. The closer the prongs are to the camshaft the longer the duration of electrical contact per revolution. Each solenoid has its own relay, prong and cam lobe. Hope this helps.

[@davidblalock9945]

I built and am patenting a hybrid version of this type of engine. I call it a hybrid because when It runs on electricity the solenoids also function as air compressor; when acting as an expansion motor they also act as a linear alternator. The end result is a system that very efficiently switches back in forth between running on air and electricity while still providing mechanical work to power the car.

Yes, they are capacitors, they each have a series resistor and their purpose is to help absorb the back emf (high voltage spikes) coming from the solenoid coils. Without them you get arcing across the relay contacts.

[@punkinhaidmartin]

davidrobert2007 Dude, that thing would be grea for a kids toy tractor. That sound is perfect. Would it help the efficiency if your coils had a neodymium magnet to pull on?

[@flyurway]

I would think since it's technically a 1 stroke engine it should develop decent torque. When considering efficiency, doesn't that have a considerable effect on the equation? In response to Mark's comment, I would think it would be simple to develop a control chip that would allow a variation of this just for the use in toys too. I don't know, seems there's a practical use for this somewhere.

[@punkinhaidmartin]

Andork Kuomo it would be interesting to see what a radial kind of merlin version would do.

[@davidrobert2007]

Hi, these engines produce very little torque, I haven't placed this one under load, but I did build a v12 variant and have a video of that running a small generator, if that may be of interest to you? Regenerative braking would be possible but fairly pointless, as these engines are extremely inefficient when compared to a conventional rotary electric motor. Thanks for commenting.

[@TheSmileyFacedPizza]

MrPollyBlitzKrieg Electricity is far cheaper than gasoline per megajoule of potential energy, and motors do a much better job turning that potential energy into kinetic energy, which makes the price difference even bigger. If you drive 30+ miles to work and 30+ miles back, then mod your car to hold more batteries. It's pretty easy to do, and it would be reversible and discreet if you're smart about it. Or use a hybrid so you can use gasoline when you need the extra range.

[@HDFoxra]

Probably already been said/asked but.... what exactly is 'powering' that 'engine'?? cause... if i remember correctly, for something to be an engine comparable to that of a gasoline/diesel engine... it has to be supplying its own power to achieve movement.. If this is really just feeding electricity into the solenoids via a battery or something, then it isn't really an engine but just an ordinary motor.

[@joehastings1]

OMG are you serious

[@HDFoxra]

Yes. This essentially is just an 'electric motor'. not an 'engine' of any type. It resembles an engine yes, but mechanically/technologically, its just an electric motor. nothing 'engine' about it in the general, everyday sense/meaning of the word. don't get me wrong, its a really nice motor and looks really cool, and alot of intricate stuff is involved with it. I was just merely curious if it supplied its own source of power for continued operation like a typical combustible engine does, or if it is simply ran off of a battery. Having it 'start' by a battery, then sustaining itself by turning the mechanical energy back into electricity via a generator of sorts, would make this much more interesting and 'cool' to present to people. Then you could just have a capacitor or two set up to store the electricity produced from the mechanical actions, and use that stored electricity to continue operating the solenoids. I dont mean as a perpetual machine or anything, just that it'd make for a fun challenge to attempt.

[@davidrobert2007]

The Oxford English Dictionary defines the word "engine" as: "A machine with moving parts that converts power into motion"

[@ionbg7]

i read basically all the comments i dont see any that are really as high priority as the questions; How much wattage(Y) is being used to give how much torque (X) = Z What is the weight of the engine/motor relative to Z vs an engine of the same weight. Well id guess that a typcal motor half the size could easily out power it, But im willing to bet a normal AC or DC motor would consume Much more power per hp/torque, I have a feeling these style of motors could prove much more efficient. The fact that you threw this together and made a WORKING prototype is amazing man!

[@davidrobert2007]

Hi, I haven't measured the power consumption, but it is fair to say that a standard dc rotary motor is way more efficient than a solenoid engine, simply because of the increased friction and limitations of reciprocating parts, as you say. The v8 here is more of a novelty, I built it for fun, but you never know, one day someone might come along and find a way to make it feasible. I'm sure every Prius owner would want this.
