Legacy Engine Assembly and Combustion Animation

[mrriteubthejudge]

entertaining but inposible to lubricate the gears and keep hot combustion from melting any kind of seal that would try and seperate engine lubricant from combustion

[AhmadAboulFarag]

I like the work but the design's idea has gone astray from the main goal, this engine exerts the combustion of the three chambers all together which leads to the point of

No.1 inertia;

No.2 Friction between excessive components which could easily be eliminated in a standard rotary engine.

I like the design thought but I think adding more components to an engine will only make it worse...

[AhmadAboulFarag]

@AhmadAboulFarag I'm sorry obviously I don't know what I'm talking about I miss understood the idea because I'm an idiot and failed to watch till the end, great idea on maximizing the power of 3 combustion chambers times three combustions per stroke.....I'm deeply sorry.

[reven92]

i believe in this, just work on it :) great minds we need

[superjoker6]

2 problems: cooling & sealing.. the power would be tremendous but not long lasting.. good work anyway ; )

[jonathanstensberg]

sealing would be an issue as the little rotors' wings separate from one surface and contact the next

[betobates]

i just look at it and ill be fun to put on the edge of the shape on the y border a wall that sticks out just in the midle of the xplotion to get like more power but this is just someone that doesnt know anything that its talking about so nice engine

[ReceptorMusic]

anyone see a bio hazard symbol lol

[d15bson]

fail

[hamsterhamz]

Would prolly produce lots of power but just too much can go wrong

[Sparviero17]

Bella ideazione, andrebbe anticipata la fase di scarico ed eliminata la sincrona esplosione del combustibile sui tre cilindri e, coordinata in tre singole fasi; questo, consentirebbe di avere una fase detonante distribuita di 90° e più uniforme.

Se l'esplosione avviene in sincrono e contemporanea, non consente al volano di assolvere alle fasi di compressione e, il propulsore si trova ad essere squilibrato.

[ecoaxial]

wow awesome concept. 3 combustion in a same time in 1 rotor.If this concept is success,the engine with two rotor will raise power equal to V12 or might be V16.

i see that there is a position which intake and exhaust port, opened at the same time. (It's remind me to 2 stroke engine).So,we must rotating the engine in high speed rotation.

another problem is, how we add some lubrication and make sure that the three-pointed star is not expanded by heat. if it's expand the engine will be stopped

[CaviMike]

This motor doesn't have any vacuum, how would it take in air? It appears it would need some type of forced induction. Also a very very fast start cycle like a turbo-prop. Probably would need a separate engine just to spin it fast enough to get it to fire.

[FliegenCockatiel]

Interesting concept, but it would really be far too complicated. That has so many moving parts, all for not that much displacement. I could see how it could have very low vibration, with no recip parts, that's the only benefit.

KISS -Keep It Simple Stupid (no offence!)

[G0dF0ther]

if the "pistons" heated up wound they jam?

[DonHoraldo]

1:06 wouldn't the fuel on the blue side be heated further. for that matter how dose the fuel get to the red side?

[sabriath]

@DonHoraldo magic? lol

[mavixp]

-mazda rx7 motors use a "similar" but much simpler principle and have a lot of abrasion/burning oil/seal problem

-your exhaust cycle seem to keep a lot of residual gas

[DragonFlyback256]

This is rather a two-stroke engine, not four-stroke.

[DragonFlyback256]

Further problem is that, it won't run clear without any type of air charging. No separate exhaust and suction chambers, they open into each. Between exhaust and suction strokes, odd type of chambers form, with suction and exhaust ports opening into each others. I really see this as the best candidate with 9 combustion during a single revolution, with a rather simple geometry and low number of moving parts (7), but the lack of separate exhaust and suction chambers is another big problem.

[DragonFlyback256]

I really like the gearing system of this, plus that, there are 9 explosions during a single revolution. IMHO the biggest problem of this is sealing each chambers apart. That one seems to be a serious problem with this. Once the sealing problem is eliminated this engine will have high power to weight ratio.

[Einimas]

this need to have two cambers like the rotary to eliminate vibration

[red33410]

Your tolerances are going to need to be too close to handle all the vibration your getting from the ignition.

This thing would be a nightmare to build, let alone, test.  Sure, it looks neat, but good luck!

[johnbell58]

Nice design, i hope it works well, but like so many of these innovative engines, they work in principle but in practice they are hard to seal

But i like the gears

[QuantumCarl]

This engine terrifies me.

[4x4le]

I think it would need a pretty heavy flywheel. Notice all of the compression is done @ the same time while there really is no exhaust to push the engine forward in order for it to compress. It would have to trouble @ higher rpms keeping itself going but I could see this engine having idle problems.

Also, what I like about it is it appears to photodetenate not needing spark plugs. Gas probably wouldnt like that though and since all firing happens at the same time there would be lots of pressure.

[AaronDC8402]

This engine runs on diesel fuel. No spark plugs needed.

[4x4le]

Yea, i figured it did this with no plugs. I guess the main problems I see with it remain the same. All of the compression is being done with nothing pushing it besides a flywheel which will need to be large. It will make a hell of a put put put put noise as the 3 combustion chambers fire at the same time. The rotating parts will have to be made heaver than what would be effecient too in order to not shier off. It will also be very important that the air fuel ratio in each chamber is

[4x4le]

identical other wise the fuel could ignite at different points in time causing power losses. The parts having to be as heavy as they need be will mean a low revving engine, which as I have mentioned this engine looks prone to low speed problems since nothing is pushing the engine in order to compress the mixture.

Im not a hater, I think its really neat! I just dont think it will work as the designer imagines.

[DragonFlyback256]

4x4le: It has already not one but two flywheels at each side if you look closely. they are holding the gears and rotons.

[sickpuppy318]

Yeah, that looks like really clean combustion to me, much better than a direct injection piston engine. Right?

This guy obviously never heard of flame propogation.

What starts combustion exactly?

VOLUME vs. SURFACE AREA ASSHOLES!!!!

[Sonicku]

clever but to many moving parts plus how is the middle gears soppuse to keep cool? whit a propper coolant system the engines life would be really short ..less that even piston engines

[SMGslimg00dy]

This is pretty clever, it would work with cooling jackets around the housing like the standard mazda rotary engine.  As for any seals, you would need 18 seals, which in that heat would go out quickly. If you could come up a way to add cooling jackets around the housing and not have apex seals, it would work.

[criticaboutvids]

i looks like it would work

[euandykes]

There's going to be a lot of friction in this motor, the exhaust gasses look to be mixing with the intake gasses. Piston style engines are still the most efficient kinds of combustion engine.

[hoodedwonder]

great idea, you should run it on compressed air instead of fuel. to keep the temperatures down

[324Ben]

The engine prototype would work,but sealing and cooling the tips would be a problem;plus , the pointed tips would lead to localized heating,which would damage the tips,and lead to variabilities in the chamber volume.

[mototrails]

It would be nice to have for show and tell would like to have it on a GO-Cart

[Mooseboy240]

Lots of moving parts to be lubricated...not practical or fuel efficient.

[pzpepsi]

the lubrication wouldnt be hard. as for fuel effficient... it wouldn't be, 3 combustions in one cycle would create massive tq and hp, but the heat it would produce might be too much

[testacorsa150]

I think so too, but pretty clever design.

The three highest points in the " cylinder" will never last, i think.

[cairun]

very nice concpet!

[sebairaf3]

very very good, what is very bad is that termic engines don't have future :(

[adamslurch71]

Actually this has less moving parts then a modern piston engine. My main problem with it is when it starts to heat like all engines it will heat unevenly so what happens when the trilobal "pistons" expand from the heat of combustion before the "cylinder walls" do?

[aa1patrol]

to many moving parts means lots to go wrong. this will be a very heavy rotating mass, slow to accelerate and decelerate. plus there are lots of sharp corners that will overheat and ignite mixture before the spark plug does. when designing don't forget "KISS" keep it stupid simple.

[Herrmanator8]

That is such and awesome engine!! way too cool. love it over the wankel.
