New water cooled Hale rotary engine 

I invented this engine 47 years ago. I am glad to see someone made it. I give full credit to the builder of this engine, very nicely done. Thomas, Henniker NH

This is a beauty Jerry! Thanks for sharing, I've been watching your other videos and reading the comments to understand it better.

Jerry, It was awesome getting to meet you this weekend! Love the premise and ability to think outside the box but stay in the carton. I also admire your ability to keep your bearing while idiots argue about your nomenclature. You are all class and excellence. It was truly a pleasure. Rodney H. from Millennium Technologies.

Very ingenious design! I hope to see it is used in real cars, motorcycles and airplanes someday.

hey Mr Hale! i always return to this video, and i will love to know how you are doing and how is the engine going :) we kinda miss you ad ur engine and i see it has gotten quite popular, hope you and you family are ok and doing well i'll love to have some updates.

Would love to see something like this with a little more oomph on ultralights. Sounds fantastic!

This would work great for a drone project I have. For long range, real time inventory of large livestock.

That is a thing of beauty well done love seeing clever people do there thing

Wow, 1 hp per lb! That is a great power to weight ratio.

You are simply genius sir. Dont know what to say. M speechless.

That looks like a powerfully small package. I think if love that in a motorcycle.

love this design, so compact.

looks and sounds BEAUTIFUL!

Very neat design, well done

I have always loved unusual and one-of-a-kind engines and engine concepts. And after finding, researching and reading about hundreds if not thousands of engine designs out there, I continue to return here. The design seems like it could be capable of an extremely wide RPM range as well as very high power output per pound. Especially if turbocharged. It would make a really cool engine for use in vehicles were weight and power are primary concern. Nearly as simple as a turbojet engine with less specialized components meaning it should be less costly and more fuel efficient to build and operate. Moving parts should have extremely long TBO and nearly impossible to break. Catastrophic failure should be nearly impossible. I personally envision this used for a motorjet type engine where the engine is buried inside a nacelle with a compressor in the front and a jet combustion chamber behind. Kind of a more efficient version of the Tsu-11 Japanese Motorjet engine.

Great design Mr. Hale...simple,. elegant, light and compact, very few parts and most parts in higher numbers.. Only one difficult formed part per four cylinders and it is small. That can be made with powder sintering followed by elektro polishing. Ideal for mass production and quick assembly. With very little changes in the design it could even be made into a small efficient compressor or an air or steam driven motor. My congratulations to you Sir!

very interesting. that blue-white smoke is a concern for emissions compliance, though, among other factors.

I really want something like this for my Back Back Blower.

I bet a 300 lb engine of yours would make 300 hp.good work sir

cant wait to see another video!!! also, ever thinked of using Electronic fuel injection? what about Turbocharging, is this engine suitable? love the engine man! great work!!

Great looking engine. Well done.

Baik!! Greetings from Malaysia 🇲🇾

would love to see the inside of this engine.

Congratulations well done.

This hale rotary sounds more pleasant to my ears compare to common engines of the same displacement.

Beautiful build. One possible problem is that all of the high temperatures are concentrated in one area almost continually. I hope you have allowed for thermal stresses in the block.

I checked out your channel hoping to see some fabrication of this. Your just teasing us at this point. We Want To See This Being Made!! 😳

Excellent Engine.10/8/2022yr

When is the next one going to be ready?

Has this moved forward?with production. Any kind of he rating?

Amazing concept, Ty for the upload. any idea what kind of torque numbers are you getting?

How rugged are rotary engines of this type? I am looking for a replacement for diesel power.

looks like a Hale of a engine!

will u plz share the plans

I love this engine design. Do you think the tech could be used to construct a diesel engine? I understand that it uses a short stroke to bore ratio, but I also understand that the stroke to bore ratio has little to do with compression ratio. The power to weight ratio seems excellent! Would love to see how much turbocharging could be handled. Seems like a very robust and well balanced design.

good job please show us the internal component parts

You built this engine? If so, had you been born 130 years ago, there would be a huge company bearing your name today. Well done. With the water jacket and mufflers, I thought it might be quieter.

Impressive work. One point though, isn't this just a variation of the Fairchild-Caminez Cam Engine?

Are you still developing this? Any new developments or builds? This seems like it would be capable if considerably high RPM and torque. Also seems it would handle forced induction well. As long as the seals hold. Does it burn oil? Sorry for so many questions.

Hi, awesome project! Do you have any info on the torque curve as well as fuel consumption?

Very Nice. How much onenthese

Liked your injane

I see it makes quite a lot of smoke. Does it need oil injection, like a two-stroke?

Nice! But why the expansion chamber exhaust on 4 stroke? Getting even with noisy neighbors? Good work Jerry.

A couple questions: I notice the stroke is very short, but the pinch area is small, so I wondering the compression ratio? Also, I watched your animation and for a single spark plug it looks like you are getting 4 ignition cycles per revolution. With this double plug engine are you getting 8 ignitions per revolution, or is there a rev reduction, or increase of some sort? As with a Wankel, the output shaft gets 3 revs per rotor rotation, or one rev per ignition.

Experimental aircraft are dying for this engine. Currently only a few alternate powered planes are out there, and I personally think that taking a 50 or better year old design and putting it in your experimental aircraft is counter to the spirit. Course I would also want to stay in the sky after I got there...

Very nice work, congratulations. Why does one side smoke and the other do not?

Good day Mr. Hale. Reading down through your comments, you say you don't see this as an aircraft engine, and I for one don't blame you for not wanting to go through the expense and time of getting it certified. There is however a real market out there in the ultralight / experimental classes that do not require a certified engine. My first thought after seeing this was that just scaled up a little, say 30 -50 hp range would find quite the welcoming in the FAR 103 (US Ultralight) arena as weight to HP is always right out there in front. With the strict weight restrictions placed by the FAA on part 103 Ultralights, (254 lbs empty weight for the powered aircraft), an engine with anything approaching a 1:1 weight to HP ratio would be a godsend. The only thing I could see that would be needed is the addition of a redrive, or maybe planetary gear reduction, 1.8:1 or there abouts? Oh, and a quick and rather accurate way of determining the HP would be to use what they call a wood bar dyno. A video of one being used on a 1/2 VW motor can be seen here - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-qCtuykIMi3I.html and there is a thread about it on an ultralight forum here - www.eaglersnest.com/forum/index.php?topic=281.msg1487#msg1487. I also have a spreadsheet that will tell you the length and cross section of the bars for the range you want to test and and tell you the HP/torch from your readings. Send me a privet male here with your email address and I'll send it to you. (works in excel or Lebre / Open Office) Looking forward to seeing more tests and development on this motor. What a great job you have done so far, and I sure hope you keep up the work. This one has real potential. I would love to get my hands on one peeking out @ ~ 45 HP. /45-55 lbs.

Impressive . I want one for my Car !!!! Can mutipul housings be added like mazdas rotary !!!!

WOW! This is an awesome piece of machinery. Do you need any technical assistance to quantify the details like efficiency, HP, torque, stresses, wear rates, etc.? I invented something very similar 30 years ago, but never got to build a running model. And I need a 1HP/pound engine to power my Gyrocopter.

How many HP @ 75%

May be one carb is running rich ?? Or one not getting Ny fuel??? Notice exhaust !!!

Genius

Looks great😃 How much power ?

I'm impressed, not many get to running stage of development. A year old now, what's happened recently, and hours on it now, teardowns?

I don't really understand how you got pulse overlap when the spark plugs are in the same position for both banks?

Bad Ass 👍👍👍

wow wow and wow

the only problem in this desgin the Friction wear between cylunder head and hole gate of rotor cylunder and another problem the lubrication

fuck yeah, dude, now make a big one with some displacement!! I'll take one with 100hp for my motorcycle!!

Waiting for table to fly away

Mr. Hale, Nice work! I can think of a number of late WWI and between the wars aircraft that would look great with that radiator sticking up and a fake engine top end sticking up out of the cowl.

⚙️👍

do you're neighbors still talk to u? lol

true Genus, how much retail

How clean is the emission?

How long did it take to build?

this desgin is better than rotary engine because they is no camshaft no poppet valve no connected rod. more small compact volume . its will be good for aeroplane or Helicopter or motorcycle please contain your inventor

only smoke from one pipe??

Mr. Hale, Hello! how is your engine? what about its resource?

Wow! That is an amazing engine. Seems like it has a lot more than 15 hp. If I may add a comment based on my petroleum experience; gasoline is the mule of all fuels. Why not use Jet fuel (kerosene/diesel) or even better, methanol? You can run these fuels at much higher compression. Just a thought, and you probably already have an answer. PS. I put all my fuel research on line if you want to check it out: theriseandstallofthepistonengine.weebly.com There's a whole chapter on it. We will be going off of gasoline soon; I stake my reputation on it. Cheers!

Call me if you need some dyno time. I'd be honored to help you.

spark plugs must rotate with piston to avoid smoke . it will be better if you rotate the spark plugs with rotor the combustion will be good without any Unburned fuel

please see this desgin ( hybrid piston / rotary engine ) copy this link and put it in youtube another idea same like your desgin with no poppet valve no camshaft no crankshaft with rotary piston

Theres no such thing as a 4 stroke rotary.
