New combustion engine design/technology. Very interesting...

 

Looks pretty cool!

Would like to see some real torq and hp numbers on it.

 

And you just thought the apex seals in a rotary engine were a problem...

 

Deffinatly a neat engine but it looks to me like there is way to much going on in there, with all those little gears in there it looks delicate

 

Hardly a new concept but their approach is different hence a patent at all. Obital of Oz had an engine that works the same way only it had one, not 2 crankshafts and a LOT less rotating mass. In their prototypes the engines were extremely small in size but made tons of power.....all of it dirty, just like this one is going to be. An emissions nightmare is all these folks have "invented". Orbital was looking for a small package for the marine industry. They made it and it was small, made tons of power, but in the end, reliability was short and just not worth the effort. I wouldn't suggest investing any nickels in this company.

 

^ They are claiming the opposite...

Because there are no intake or exhaust valves, the combustion chamber can be designed for optimum combustion efficiency. Direct fuel injection in the center of the cylinder chamber and spark ignition in the center of the piston also insures a clean exhaust (for diesel it allows for optimum piston configuration).

 

Sorta reminds me of the Wankel Rotary that Mazda used to tout.

It was supposed to change the engine world also.

Only time will tell, but all those rotating masses have to have some sort of gyroscopic effect going on, eh?

 

'Bout time they started using ceramic cylinders.

 

I didnt read the whole things, just watched the videos. Where does it get clean air from? Not understanding the intake and exhaust design.

 

That thing has got sound pretty strange when it runs. Probably pops like a wine bottle every time it fires.

Looks like it just gulps air when the piston isn't in the cylinder. Problem there is the air it is gulping is the exhaust that was just spit out. Someone said it earlier, probably pretty dirty.

 

Lots of WW1 aircraft used 'rotary' engines, just not the same principle as these newer ones.

The cylinders rotated around the crankshaft with the propeller.

Radial engines won out cuz of the gyroscopic effect of large rotating masses.

I notice the 'flywheels' (alltho they don't call them that) rotate in opposing directions like propellers on twin engine aircraft so maybe most of the effect cancels itself out??

But in the end, it's an internal combustion engine which uses fuel, so I don't think it's gonna solve the energy problem.

 

Well compared to a standard piston-engine (they claim 13% efficiency, but I believe 18% is a better number), they are claiming 45% efficiency, so you would get more work out of the same amount of fuel vs our engine. To me the site is just trying to find some investors.

 

^ Bet your right too.
