Devize Engines 4 Cylinder Axial Barrel Engine - Operating Principles - Walkaround - Tuned By Shane T 

Brilliant, all the best inventions are created this way, effort driven dedication!

Thats awesome. Its great that people can still do cool projects like this. 🤘🏾🤘🏾

This is amazing! Thank you for taking the time to educate us on this badass design. I can't wait to see more.

I went to school for HVAC back in the 70's and the GM a/c compressor had a "swash wobble plate" design and this looks like it derived and expands on that idea.

What a crazy piece of engineering!

I underwent RAF jet pilot training in the 1970s. During the technical ground school we were shown how the high pressure fuel pump on the Viper engine worked, which was surprisingly similar to the principle of this engine. An angled, rotary swash plate pushed and pulled a series of pistons, arranged concentrically around its shaft, up and down their bores. The pistons drew in low pressure jet fuel and expelled it at high pressure. As a keen motorcyclist and an amateur mechanic I desperately wanted to get hold of a spare pump and try to convert it to an engine for a small bike. The problem would have been lubrication, I would have mixed 2 stroke oil in the fuel.

That is insane. Beautiful!

Very cool project. Going to be an uphill battle for a while on that one.

This Is literally BRILLIANT!!

I thought I saw something about this engine design a few years ago, but either way, it's super cool seeing it getting close-er to actually running👍

Unreal! Love it.

Super cool video.

Thats cool, almost like 2 axial ac compressors stuck to each other

Are you aware of Smokey's Adiabatic engines? Quite Novel, powerful, efficient, omni fuel. DCP Rep took a K model with Smokey's v twin (75 cu in), drained the tank and filled it with low grade regular, put it in 3rd gear and leapt on the interstate trying to make it ping. It grunted and moved. FLM and GM had their own bottom end models tested the same. Smokey made the V twin, inline 3, and a V4 that produced over 350 HP and needed no cooling system, in fact you could put your hand on the exhaust header at full power. The heat was kept in the engine. Reality is about someone's profit margin...

I'm surprised you didn't reference the huge amount of research done by Detroit and Commer that this design has benefitted from. Most of the technology on this is well-established so it's definitely not an invention regardless of whether anything's patentable - the opposed piston approach was refined commercialized by Commer and Napier mid-last century, the blower/airbox/liner approach General Motors refined and produced (in massive numbers for most of last century), and the swash plate is quite common in hydraulic engineering. So really credit should have been given to those. Regardless, I'll be looking forward to seeing the performance numbers on this, along with efficiency stats and maintenance discoveries.

Wonderbar !

Awesome of you to show the behind the scenes of how difficult it is to deal with some of these engines from the engine management side. Do you plan on releasing a video going slightly more in depth of all the changes from a standard build you had to make, or is that out of scope/trade secret?

This reminds me of an engine the Roots Group made in the UK before Chrysler bought Roots and had almost everything destroyed. Only a few engines survived. I think they were naturally aspirated. Not twin charged like this one. But they were still pretty powerful and very torquey

Iam happy that this is allready build....

Very interesting

You could hear the frustration on fixing the code logic for the deactivation lol.

this engine is the engine of the future.

A simple 10 second animation of the inner workings would’ve done more to explain this engine than the 13 minutes 53 seconds of the time that was spent. Very cool engine though.

Bud, I consider myself to be a fairly sharp fella…….. but that thing is bananas

The idea of distance from the crank center being separate to stroke has some interesting torque advantages, as does tdc dwell for possible lean petrol hcci?

Fun project Shane! Question regarding the flapper valve and its use to deactivate cylinders. Looks like a repurposed electronic exhaust cut out is being used. Can you expand on how that will function? The valve isn't fully sealed, or is it? Love to be there to lend a hand! Will be subscribing for sure!

So a swash plate design for the crankshaft a bit like a hydrostatic transmission or high pressure pump similar to a lot of pressure washers

Reminiscent of the DynaCam engine. It worked, but it wasn't scalable.

I see you visited the ATA Chapters 71 through 80 section of Home Depot for some components on this prototype 😉

Thanks for the update. Why a hydraulic starter? For variable speed?

No mention of reed valves, is the fuel mixture not routed or controlled the same as traditional two strokes ? Some great projects you get to be a part of Shane, thank you for sharing what you can on here 👍

I had a very similar design I drew up in 2007-2008, but I had a spinning plate that was flat on the cylinder side and slightly conical on the other, connected to the center shaft on the top of the cylinders with a semicircular slot for intake/exhaust rather than valves, then a turbine compressor like a jet engine on the front with a gearbox connected to the center shaft that would blow fresh air and push exhaust out around the outside of the engine. I’d intended it to be an idea for an aircraft engine…

I've been following this engine design since about 2007 and have yet to see it running what gives

The cams don't turn "back and forth" (as mentioned @1:14); they rotate continuously, which is the point of these complex schemes to eliminate reciprocating motion.

Seems internal friction is probably the reason these type aren't more popular. I'm thinking swash plate type deal like many AC compressors. The wear, heat and friction just have it gobbling itself apart from the rip.

This looks like a cam version of a Commer TS3 from the '50s

It would be happiest at a semi-constant speed and high rpm? When you say compression, what's static compression? Will it run without turbo's and blowers??

Very interesting design. I hope the development continues. One question why the supercharger blow to the turbos? It's more common the turbos blow to the supercharger. Like the two stroke Detroit diesels

Looks like a variation on the Dukes design . A PROVEN fragile design .

Great accomplishment but what incentive do manufacturers have to adopt it?

So is this essentially a piston port two stroke? Will this be able to handle modern emissions standards and if so how are they overcoming The inherent tendency to blow unburned fuel out the exhaust on a piston port two strobe?

Please could you build the same concept but with an axial opposing piston ... Six cylinder, 12 pistons with a swash plate. Thanks

The choice of hydraulic starter really has me wondering about all the internal resistance I suspect plagues this design. With so many other options. Air, electric I can only think the power demand on starter mandates a pump and starter of this type. Please explain if I'm missing something. Built that entire motor but can't figure how to get 220 to it and fire it. I'd be robbing 120 from two separate circuits and hearing it run. As a machinist I can appreciate the fab and engineering involved but I know there have been hundreds of thousands of brilliant engineers over the decades and there are very legitimate reasons why wankle, rotary and this type motor aren't in heavy use today. I can think outside often but the realist in me says LS swap whenever you want very extreme, low cost, HP. Good luck and I would love to hear if I'm all wrong about this. It's interesting and I do wish success if it's not just a gimmick to draw non mechanical minded investors and then a couple guys drop everything and walk away with all the cash. Seems to be how those so called educated types operate these days. Zero integrity, looking over their shoulder but living big off others hard earned money.

I remember seeing a barrel type engine being developed by a gentleman from Mississippi about 15 years ago. He raised a fair amount of money and leased at space at the Stennis Space Central on the Gulf Coast. I was part of the initial round of fund raising. I have not heard much about that particular project since that time. I did not invest. Could this be the same technology?

Really cool concept, but I cannot understand why the trubo would be downstream from the supercharger 🤔. You have a positive displacement blower so I don’t understand the reason for the turbos. If you want added boost from the turbos it seems like they should feed into the blower

This dude is speaking my language

What about piston lubrication ?

With the swashplate, isn't it essentially the same as a sterling engine?

Looks like a simple setup, what could go wrong?

having the form of a sine curve. "a sinusoidal waveform" 2. ANATOMY relating to or involving a sinusoid. "hepatic sinusoidal thrombosis"

Yeah I need an exploded cartoon sort of do I can't picture the inside of this

swashplate engine? How does he manage the friction of the plate?

Seems similar to the Alfaro engine from 1938, I'm very interested in cam-plate engines like this. I'm wondering why there seems to be not much information available on this company Devize Engines? Do you work for them? It is obviously quite far along in development to have a working prototype, but I can't find any external information on the company.

To anyone who’s wondering why this engine looks familiar, they basically just enlarged a rotary ac compressor and turned it into an engine

interesting

Gentlemen start

Why has no one mentioned the issue of mechanical advantage here? With a swash plate being used to transfer reciprocal motion of pistons into axial motion surely the torque output would be terrible, with massive loads on the swash plate. This is why they work so well in pumps as everyone else has mentioned, I can’t see this backwards application producing any sort of useful output

You know...looking at this design you dont really need pistons or rods. If you took the two counter rotating planes, and used that as the combustion chamber. Like a sideways twisted Rotary engines contracting and expanding combustion chamber! Ooof! Oh my, after a bit of thought, you could adapt meshed counterrotating helical halves, (opposing meshed rotating spirals) Yikes, this coffee is strong today!

At least it’s not complicated with multiple different systems relying on each other so it functions 😂 I see gm or ford loving this nightmare of a setup!

You need a support bearing on the crank shaft pulley or you'll see a rapid fatigue failure on the crank shaft. Where you're pointing at it you're saying the supercharger is two speed.

Very impressive build, but at 1hp per pound, what's the advantage? A small block Chevy can easily do that and more.

Why would you feed the turbos with the super charger you’d get way more power feeding the super charger with the turbos?

Is this for an aircraft ? a boat ?

Thats quite an old design. One of the biggest problems is the sliding friction on the squash plates.....

Why call it a "pseudo" intake manifold @5:20? It is simply an intake manifold (consisting of a ring plenum plus elbow runners).

So what do these power?

10:50 good ear

Works just like an AC compressor. Basically.

Does it run?

Whats thé power can you get ..size engine . Weight !!!

"Sometimes it's better to not be so complicated". Amen Brother!!! Exploration is the Human endeavor. What if? But "we" can't be satisfied with what is. We think what was missed? (The Father won't let us dream what we cannot do). :-) I built a 4 axis high performance simulator. 5' vert, 4' linear(axial), 50+ deg and 40- deg pitch, and 360 deg rotation, all in one second. What a ride! Far from cheap, anyone want one? (Got vids)

But does it run ?? Basically it is like a oppose piston 2-stroke diesel but with questionable design.

I like the idea of people working on new tech and ICE, now this system seems to complicated to be reliable. Make it more simple or my favorite saying "keep it simple stupid". Keep up the work just make it a lot more simple so it can be cheep to make.

How is the fuel efficiency??

Check out Cummins ACE engines!

So it works like an AC compressor.

Y'all took apart a car's A/C compressor and thought 'we could make an engine like that.' Also, those things are called swash plates.

Why not using an elektric starter... it works as 2stroke?

It's a swash plate hydraulic pump in reverse.

It looks cool in the idea sounds cool. But a four-cylinder with only two working sometimes. The other two not. I'm not convinced. it seems like you could do some of four or all of four. That is my two cents. Nice job so far though

1:12 Back and forth

Why a hydraulic starter?

your boost is going to be compound boosted.............

yea but is it fast?

Swash-Plate Axial IC engines incur huge tribological/lubrication problems. This is avoided by using the Z-axis, wobble-plate design which employs fully articulated rolling-element/she'll bearing joints. Why did you choose such a problematic design?

It’s just a version of a hydraulic motor with a swash plate.

1:15 no Back forth

Well,,that left me completely not understanding how it works,,or it advantages,,

It will suck oil past the rings when the intake is closed off on cyl. two and four.

its not what you would call compact?

So it's an opposed piston duke engine? 4-cyl kinda lame, tho.

The "unique" feature of customising the port-timing by designing the cam-profile characteristic has already been done decades ago in the K-cycle axial engine.

Axiel piston array.. no like you say

Electric starter would have been so much cheaper and easier
