@KnightKadir , 787b rotary wankel engine produced round 600Nm of tourqe, the same engine won the La mans race, they know what are they doing better than you and me...
Idea and visual explanation exellent.But its pitty the commercial matter till now rotary engine not popular in market.Try to catch the market.best wishes.
that is one Noisey engine for sure! The rotor is bearly rotary. This engine falls somewhere in the middle of a wankle and piston. Notice the abrupt change of vector direction, of the rotor. There was a reason why the Wankle has a figure-eight shaped chamber.
i dont mean to sound stupid but where is the combustion taking place? is this like a two stroke? because all i see is induction on the downwards rotation... then exhaust on the upwards one... hmmm im confused!
this dont seem like it would be very good cause the rotors if you'd like to call them are just going from top to bottom top to botton and theres no room after the ignition
This one fires in two very different places. from the 13B. It is a bit more complex but looks to be something more like a reciprocating pistol engine than the Pseudo Turbine that defines the Wankel-type rotary. The result should be smoother operation over a Pistol with better F/econ and reliability over a Wankel.
A rotary engine with valves... Well that kind of gets rid of the major thing rotary engines had going for them. Its going from the 3 combustion cycles per rotation on a Wankel design to two. Interesting none the less.
Actually, a rotary engine has one combustion cycle per revolution, per apex. That means that a 13B will fire twice per rev (or once for each apex), with each ignition event occuring @180 deg intervals.
The main thing that rotaries have going for them is that they are the only engines that can run on a 2 stroke cycle efficiently.
You are quite right on one thing; a single rotor fires once for every revolution of the shaft (only one face of the rotor fires per shaft rotation, it takes 3 shaft rotations for all 3 rotor faces to fire).While a rotary engine can both work as a two stroke or a four stroke engine, all the current rotary engine works as four stroke. A two stroke rotary engine usually have spark plugs on both sides of the housing and would fire 6 times per rotor rotation, but no company is currently making those.
Not at all, stroke refers to the cycle of an engine.Four stroke refers to Intake, compression,combustion and exhaust cycle. So, it doesn't matter if it's a rotary ,reciprocating,nutating,wobbling, or even a turbine engine.
Many people make the mistake of thinking that strokes refers to the Ups and Downs motion,that's wrong. Remember,there are also 3 stroke, 5 stroke, 6 stroke ,brayton cycle reciprocating engines. You don't need to take my word for it, just go grab any engineering thermodynamics book or just do online technical search for engine cycle/stroke.
Since each stroke of the piston is a phase in a powered cycle, stroke does refer to piston travel. Equivically though, a rotary does complete all 4 phases independently, just like a 4 stroke - therefore, you are correct in stating that it does work on the 4 stroke principle...
Sorry, I got a little confused when I noticed that it fired on every revolution. I ignored the fact that there are four quadrants in the apex housing.
Take some time to think about it. It is a very good concept. It will not have vibration problems. It uses the same seal design as the proven wankel. Power to weight will be excellent due to double firing system. Excellent!
despite the potential flaws, this is a work of art and a high level of visualization. Good job! Now, an ordinary rotary does not attempt to occupy any corners. Thhis was/is probably a tradeoff between volumetric efficiency and vibration. Compression could easily be changed with a divet inthe rotor. As with the newer wankels, the ports could be side mounted and sufficient clearance used with apex seals and traditional lubrication system. This one's double firing makes for smoother compact power.
Waste of time. Besides anything else it has the same probs as the existing wankel. Poor fuel economy and it would burn it's own lube oil so emissions would be an issue.
i think the problem is whether or not the cylinders will work right. i mean the way it ends stuck up in that corner... the vibration will fuck the whole thing up... besides the compression ratio seems awfully high, maybe too much stress on that "crank"?
indeed. plus, the way the rotor awkwardly presses against the walls would wear the whole piston down, causing it to lose compression drastically.i dont see how you can efficiently oil that that system. it would wipe oil into the combustion chamber, if you can call it that. there is no way to dip the moving parts in fresh, cool oil, which is highly necessary for these high friction conditions.
Hmmm...Interesting...Looks a lot like a Wankel engine but with no need for seals on the corners of the rotors...I dont like the way two sides of the rotor stop up against the cylinder walls...Thats sure to be clunky and cause vibration IMO.
a rotary rod like piston rod must be necessary for higher tork of rotary engine. i think mazda should see it

counter rotation... no that is not an additional failure feature

This may sound tard but I have a few questions:
1). Where is the spark plug? Is this a diesel engine or does it run on olive oil ? :P
2). As per you illustration, during the compression phase the intake valve seems to be open, how does it trap/compress the air?
3). In which phase are you igniting the fuel and getting the power from the engine?
4). MOST IMPORTANT!!! could you please use english to explain the parts and phases/cycle?

I like it. Very clever! Good variation of wankel. I hope it uses less pieces and consumate less oil.
Good work! I hope the best!

Actually, 2 and four stroke priciples only apply to recipricating engines. I made a mistake there!
