PAUT ENGINE -
Prototype 2 is performed as an engine with two-sided pistons, positioned at 90° to each other, in combination with PAUT two-stroke cycles (fig 1). Such construction provides an engine containing less assembling parts, having smaller mass to power and overall-dimensions to power ratios, which are the presumptions for a successful product to be accomplished and for low cost production/exploitation to be expected. Smaller mass, compared to the prior art engines, derives from the fact that PAUT engine contains considerably less assembling parts lacking elements such as: rods, camshafts, camshaft's driving parts, some valves, large heads.
The very construction of the two-sided piston (fig 3) has more advantages. Contact area between two-sided piston and cylinder is considerably larger compared to prior art pistons. Hence, specific pressures are lower and since the two-sided piston is lubricated under the pressure, the friction is considerably smaller, the more so as we know that normal force Fn in the engine center equals zero (fig 2a).
All these results with less wear of the piston and the cylinder. Such a two-sided piston has considerably smaller mass compared to the prior art assembly it replaces, consisting of two pistons with their prison-shafts and two belonging rods, resulting in lessening of linear motion inertial forces.
This construction has still more advantages as compared
to prior art engines such as:
- better controlled cooling of cylinders not being adjoined to each other
- smaller friction inside the engine due to less moving parts
- increasing the capacity of this engine, though considerably, results in overall dimensions to increase only slightly
- gravity center is posted lower (it is in the engine center)
- better forces configuration in the very engine, while negative forces and torques nullify each other completely (fig 2b)
- it is possible to dismount pistons and cylinders without entire dismounting of the engine
- no special tools nor machines were used to produce this engine
- there is less noise due to the design of the two-sided piston
- though the cycle is of two-strokes, the lubrication is performed as if it was four-strokes
The objections on this construction should be as follows:
- due to the compressed construction , the starter should be mounted on the gear box, but with some endeavour it is possible to mount it on the very engine
- the force on the output journal of the crankshaft (fig 2a) is twice compared to the one at prior art engines, but this problem becomes negligible with a proper design of the journal and of the operating shaft bearings
- there is no oil sump at this engine, hence an additional oil-pump is needed
- since it is a two-stroke cycle engine, the engine cylinders are submited to higher mechanical and thermical load comparing to four-strike cycle
Prototype 2 - characteristics (technical data):
• Two-stroke engine
• Engine-block measurments with heads mounted 500mm x 440mm x 440mm
• Engine two-sided piston diameter 100 mm

• Capacity 7000 cm3

Very interesting concept and nice animation. I wish it will be manufactured and tested to prove its advantages.
Congrats to all inventors and their inventions. All mankind needs people like you guys. Modern life is full of great and useful inventions. Depends on us to use them well. This motor is astounding....Congrats again!!!!
Put the journals at the center of rotation, put the parallel cylinders going opposite directions. This will simplify the engine further and reduce vibration.

It substitutes for using connecting rods. The pistons are connected right to the crank. The crank throws themselves make the motion that conrods usually make.
Due to the lack of connecting rods I believe this would be a high friction motor. Lateral movement and all. Beautiful concept.

It's a 2 stroke.. changing plugs is normal on anything burning petroleum gasoline, no oil changes. Oh might need an air filter once in awhile.
Nice concept. Needs major crankshaft counterbalancing and the middle of the crankshaft needs support. The center of gravity of the crankshaft rotates around the axis of rotation of the crankshaft which would cause major vibrations. The Paut cycle is similar to the split Scuderi cycle and will have transfer losses between the compression and combustion cylinders. Would be interesting to see in a standard 4 cycle config with proper counterbalancing, cams, and valve train.
I actually designed an almost identical engine to this, but I couldn't get passed the cam movement on the crank. It never occurred to me to make the crank ends eccentric. Good job. Its nice to see this become successful. I hope you can perfect it and get it on the market, in whatever way you can. This design is not only more compact and lighter, with less moving parts, it seems it will have more potential power, because of one combustion per revolution for each two-piston chamber in the four-stroke version. The conventional four-stroke has only one combustion per two revolutions of each cylindar. Although there are the same amount of combustion strokes per revolution of the crank, the shared lobe per each two-cylinders is what sets this apart. also, the horizontal and vertical movement of the one rod per two cylinders is also a plus. Allowing for higher RPMs, because there is no sideways centrifugal forces putting a 360 deg strain on the piston rods. A back-and-forth motion seems much more efficient. Bravo !
Looks very promising! More efficient movement without extra parts.
The piston-rod-less engine principle is known since 1920's. In Soviet Union known as Balandine's engine. It has been built a large number of prototypes during 40's and 50's (see ОМ-127РН aviation engine, for ex.), and got few followers in modern time. The major drawback of the design was a requirement for highly accurate synchronization of the "left" and the "right" sides of the crankshaft == precision machining was required implying high manufacturing cost. Low manufacturing tolerances resulted in excessive wear, fully diminishing the advantages of the type. Another disadvantage is low output torque. The engine in animation will not turn in practice, the crankshaft will be immediately jammed due to misalignment as there is no synchronization implemented at all.

I really like this compact design, but I see bearing issues coming into play. This design does not have enough reinforcement of crank shaft centering as it relies only on the pistons and crank end eccentrics to enforce crank shaft center line location, without any dedicated main bearings for the crankshaft. Adding main crank bearings to the design is going to make the things substantially larger, but it would still be very interesting.
Thumbs up just for stairway to heaven. Nice version
What a wonderful design! I think its ingenuity lies in the fact that there is one larger set of pistons on one side and two smaller ones on the other. The difference in mass on each set is fairly well-balanced due to the offset in the crankshaft revolution (the semi-concentric "sliding" motion of the crankshaft.) The external balancing is achieved by the counterweight on the flywheel. PS: I love the choice of background music! "Stairway to Heaven" in a languid bossa nova style! Very elegant!
Not sold on the engine configuration, but this is the best presentation/explanation of an idea I’ve seen in years.
So it is part radial and part boxer ? What fuel can this use ? Diesel- Gasoline ? What is the limit for down size ? I like it, the construction is marvelous. I guess this would be a heavy piece in motorbike frame but that depend on power to mass. BMW and Harley engines are heavy too.
it's like boxer and inline engine together
What a great concept. compact size, less moving parts, simple and innovative.
I think the concept of ofsetting the crank such that the sections holding the pistons go straight up and down while the wobbly ends transmit power is amazing - eliminates connecting rods
it is good concept... it wants most powerful camshaft ... keep trying to develop this ...
The large counter weight on the flywheel will go someway to reducing vibration but the crankshaft would fail under any sort of load. An offset counter weight on the crankshaft would be a better option and also a center bearing point would create more reliability with only minimal length gains to the unit.
Fantastic animation. Rest in peace it’s designer. I can see vibration and wear possibilities, however I like the supercharging effect and as a concept would produce interesting results if it were ever built. I’ll watch this space.
As the German car manufacturers are going to dominate the EV market soon, this engeneering marvel is ready to go straight away to the museum....
It is a beautiful design. I have often thought that another cylinder that adds compression was a innovative idea, however I gave up on the idea due to the frictional/weight gain without the power gain. There is the weight of the slave piston, the friction from it's rings, the weight of the cylinder and head. It just makes more sense to me to use those cylinders to produce combustion power, not be parasitic.

except in the case of a two stroke , mind you, a non reciprocating supercharger would create less vibration for scavenge air..check out the evolution of the dkw laudepump 2 stroke bikes from the 30's.. same concept basically, this design just re arranges the crank shaft, and goes '"big bang" stlye, as per the nsr race bikes of the 90's.. these motors gave a wider power pulse that did't destroy the rear tire or break the contact patch as abruptly as a cross plane crank did.. though through electronics they managed to mitigate the tire eating effects of the motors, as well as tire tech caught up, and the smoothness of the cross plane got better drive mid and out of the corners, (See Mick Doohan).. yamaha has managed to perfect the power characteristics of the M1 gp bike, giving Rossi a dominant package, and we can see him drive off the corners harder than his rivals, flat planes make crap low end tourque too, but excel in high revs, the 427, in the gt40, and the 302 coyote are flat planes, n rev to like 8000, at the cost of being peaky n not very flexible..
How does he figure the forces balance themselves out? This is an extremely unstable motor and a horrible design that would never work. It's gravity is not centered at all. The crankshaft isn't even in the center of the motor, it's not only offset, but it's eccentric offset with the same vector as the piston direction. There is no counter-balancing force in this motor. The crankshaft in a normal motor has counter-weights on the back that transmit the force exactly equal to that of of the piston and rod. This motor lacks that. Even in horizontally opposed motors you have to counter-balance the pistons.

The crankshaft IS central. The long eccentric shaft that runs through the whole engine is just a guide for the pistons. The ends of this shaft are seated in the holes on the end disks, which is where the power transfers through. Honestly this design would be much better if it had gears to encourage rotation of the eccentric shaft.
If it still runs on oil, we dont need it. Respect for the invention!

All of your replies are that this engine is a two cycle engine. they are right. no valves needed in 2 cycle engines. every time the piston compresses the fuel/gas mixture, it ignites. twice as many times as in a 4 cycle engine. These engines have a wide power band and work at much higher RPMs than 4 cycle engines.
Love this concept ! I see an electronically controlled valve-timing 4 stroke in the future of this.

A very unique mechanism to substitute for a Scotch yoke with rigidly paired pistons, impressive! High wear probable at the pin-in-slot orbiting mechanism, thin pin contact patch, with sliding blocks better. The many critiques of balance expressed here have merit. The 2 opposed piston pairs moving in concert with each other, in both intersecting planes, rather than the damping effect of opposed reciprocation.

Quite true split-cycle engines are not something new, but heavy pistons are not mandatory with the right materials. Most of the piston's volume could be made of aluminium with carbon, steel or other incursions where needed. The biggest issue is the 2-stroke cycle, but I don't see anything preventing this design to work in 4-stroke. Second big issue is the simple fact combining the compressor and the engine pistons in the same block means there's no compressed air cooling and it even heats up, which will prevent it to work with a gasoline-type cycle.
Very interesting, love the compactness and the long dwell times at TDC and BDC. My main concerns would be vibration control with both vertical and both horizontal pistons firing in unison. Also identifying harmonics within the crankshaft as all loadings along the shaft would be transferred laterally to the pistons and change through each degree of rotation. I am sure that can be calculated but it would need someone a lot smarter than I am.
It looks very balanced, rigged design and space saver. Brave, an idea out of the box!

I like the idea of the engine compressing its own air. I also believe this could be balanced with a slightly different crankshaft. It would produce a lot of vibration. As far as compressing the intake charge though. ...the compressor piston needs to be substantially larger than the one used for combustion in order to truly be effective. They could also be very lightweight because no combustion would be occuring in those cylinders. There is a reason turbos are so popular. Its an extremely efficient way to get forced induction with very few drawbacks.
But can I boost it with a turbo?

Right now, electric cars are iCE still needs to exist and be made more efficient as long as we’ve not perfected electric. Oh, aircraft will always need to have non-electric engines, because of power storage density and the fact most aircraft weight is in fuel, and batteries will always weigh the same (or close: perhaps something can be measured for difference when discharged) at the end of the trip, while liquid fuel is burned and flight becomes more energy-efficient as the fuel weight is removed.

It's a two stroke engine. That's not very good. Also, from your diagrams, it looks like that compressor isn't doing anything. The volume of the cylinder and that of the compressor are the same, so it's just like natural aspiration, only worse cause you have to compress the air just to return it to normal pressure. Needs a redesign. But it would be an interesting layout idea for a normal V8 engine.

***** To continue your thought... The lack of main journals to absorb the force needed to convert reciprocating motion to rotary motion would lead to crankshaft bending even if the end mechanisms do manage to sync up the circular end motions of the crank. The assumption seems to be an infinitely rigid crank. Probably requires at least 2 more main journals (probably 3) and then they would have that circular-ish motion to contend with as well and add (again, at least) 40 mm to the block assembly length. Oh, and each of those 4 bearings looks to be rather complex (expensive). Capacity is also miscalculated. Only the displacement of pistons in working cylinders should be considered and with 691 cc per cylinder that amounts to almost 2.8 liters total for the engine (which is still a fairly large 2 stroke engine).

The revolutionary part is the crankshaft design that eliminates the piston rods.
Reinvenção da roda! Qual é a inovação desse projeto, além da disposição dos cilindros?
The first thought that sprung to my mind was VIBRATION... Good Lord Vibration... Take a look at the "Revolver Engine" WHY it is not in worldwide production is simply a result of Big Oil Design suppression. I was impressed by it and it was certified for AERO USE ALREADY....back in the 70's ! NO SMALL FEAT !!
There is a lot to like about this engine design. IF it proves out to be actually functional and operational, it would be a real gem. There will be breathing issues because the piston does not linger at the bottom of the stroke due to the elimination of the column effect due to not having a connecting rod. I would love to see this thing prove out and implemented.
This exact same engine has already been designed and actually built by a guy in California in the late 1990's, except it wasn't 16 cylinders, but only 4. Just google the words "Trammel Engine" or "Trammel Motor" and you will see the build page. It is a very good idea.
fantastic ! Well done !
Thanks for good music. This is old idea of russian Balandin Engine since 1940s.
I agree with putting the support in the middle. Looks like you would need to add to the length to throw counter balance into the crank anyway (maybe scallop out the journal you'll be moving or adding to the middle of the engine). get the diameter way down on that's actually exiting the block or you'll leak oil like a sive in no time. Just move the seals from the journal to the the actual output shaft on the rear and do something similar on the front. if you want to charge it I'd do turbo or put some gearing on the front end for a centrifugal compressor. You have no valve train in there yet and this thing is asking for a radial inlet and exhaust. by the time you do that you won't be able to air cool it even in an aircraft..... at least not well. Very neat concept, I'd consider just going with a boxer configuration though so you have less plains of vibration to deal with and to give you the room to do all the other items listed above. That and if you wanted to put this in a car it would maintenance easier (think about how many angles you've got to walk through to get to all the spark plugs.
thats is a great engine it looks so harmonious .

Very elegant design, at first I couldn't wrap my mind around this design, but now that I get it a few things come to mind, 1 it seems like a low rpm high torque engine and it would probably require a larger that usual flywheel to be able to idle, 2 having no support on the crankshaft other than the front and back reduces friction but increases load on those two point, in fact the tremendous amount of stress in the rearmost bearing of the crankshaft will probably make the bearing fail often, 3 been some kind of breed between a 2 stroke and a 4 stroke it has the worse of the two types, it's truly a 2 stroke with added intake valves that create more friction and it doesn't not have the airflow properties of a 2 stroke, therefore I requires some kind of supercharger or and air pump like the one in the video, 4 vibration shouldn't be a problem. It is a really nice project but other than being a good hobby I fail to see and advantage over common V8's
That long crank shaft, without journals in the middle only at the ends in the block, will have torsion affect from centrifugal force and reciprocating motion of the parts attached to shaft. I would have add the middle point journal the same eccentric unite as is at ends in the block. Still give you a lot of credit for creativity, and thank you for keeping America innovative .

Another fascinating engine concept.
An engine that I will adorn the name of an X8, has the same size as a V4. Seems pretty revolutionary to me. Double the power in the same space.
Beautiful !!!!!
I've heard of a cross bolt crank, but hell that's a cross bolt engine!
Great concept quick question how does oil travel through the system is there oil reservoir that's somewhere else and coolant as well?
Ingenious!
really revolutionary idea
brandan: This engine seems to have a very large amount of reciprocating mass in the pattern on the circle shown at 0:20. Is there any way to offset half the cylinders 180 degrees, or does the engine require a large counterweight? (the one on the flywheel seems inadequate)
This is amazing 👏👏👏
seems like a great idea, except i wouldn't put holes into the piston's top surface even though the bolts are gonna go in there. Remember, its gonna build up carbon and rust too if there is too much ethanol in the fuel. You're gonna be more worried about even having access to the top of the bolts rather than trying to break the bolt loose. Since the individual cylinder walls are removable, put 4 bolts total per piston on the side of it. Make the piston insert eachother like male-female cables. You go enough room and metal to make it work well. Another thing, how exactly are you gonna machine down the crankcase? If you do it out of cast, its not gonna work very well tolerance wise.
Bravo! Samo tako dalje!
Looks great. Please put one in something.
Absolutly genius!
Am I correct in thinking you get a combustion on every 1/4 turn of the crank?
I love the X8 concept. Would love to see what it puts out in terms of torque and hp
Worth watching just for the soundtrack.
