New Piston Engine Design - Scuderi puts another twist on the Otto cycle
http://www.scuderigroup.com/technolo...echnology.html
really interesting idea. the ability to get supercharged performance without the extra equipment is really cool.
Hopefully this design will take off in the future if its really better. More power, better economy and efficency, whats not to like for the bonger crowd ?

That's pretty neat, basically splitting the cycles from one piston to two...but it would take much more space. From what I'm getting, at the end of it all it is like a supercharging effect, but without the need for catalytic converters because it burns so cleanly.

Studies showed engine efficiency increases from 33% to almost 40%
that is promises to far exceed current efficiency levels.is expected to deliver a quantum leap in performance, efficiency and environmental impact.

I think the quantum leap is in the reduction in emissions. 80% is a huge reduction. If they can get this out of the shed I think it would be revolutionary. Just look at variable-valve timing, when 15-20 years ago, people were like,"What's this V-tech thing?" We'll just have to wait and see.

That's a very interesting concept. Definitely outside the box. I like it but then again I like alot of experimental ideas that are different regardless of if they have potential or not.

it seems able to work in theory, but its still using the energy from the crank to compress the air/fuel mixture. now if the power stroke piston was able to move once for every double stroke of the non-combustion piston(maybe a seperate mini crank), then maybe double compression could occur, but remember double air does need more fuel.

Cool design and nice idea. I see the efficiencey benifits. Correct me if im wrong but for every one cylinder's job in a convertional engine, there must be 2 in this new design to complete the comustion process. so to get the power of a v6 you must have 12 cylinders? I may be just looking into this wrong but wont that just add tons of weight and unneeded complexity.

If you look at it, the plug fires every cycle like a 2 stroke although it isn't a 2 stroke. The other 2 cycles from a 4 cycle are taking place in the adjacent cylinder.

Looks to me like there would not be any additional complexity to this design aside from differences in the functions of the two cylinders. Instead of each cylinder having to complete all 4 parts of the cycle: intake, compression, combustion, and exhaust, one cyclinder does intake and compression each cycle, and one cylinder does combustion and exhaust. The only issue I could see with such a design is the intake/compression cylinder would have very little wear while the other cylinder would have significantly more wear due to the increase in number of combustions it has to withstand.
I think the idea is great because it allows for specialization in the cylinders: ie like how an assembly line is more effient because each person has only one or two tasks to complete rather than having to do all the different tasks, some of which he may not be suited for.

To me this seems like a gasoline powered version of a diesel engine. But thats just my opinion.
But I guess we will have to wait and see if they actually can put this idea into a production model. IF it does, then who gets the right to use this new and innovative idea?

It's got no valve overlap between intake and exhaust. Alot of progression in engine technology seems to be inching towards this trend. Some of the newer prototype next generation piston engines that use no cams and have infinitely variable valve timing and lift are also using no overlap although only at no to low loads. We'll see these no overlap engine hit production within a few years. When we could expect to see this new type of engine hit the market is anyones guess. We see alot of neat ideas al the time but never see any of them go any farther than the webpages they are shown off on.

What doesn't make sense to me when you look at it from the side view is that the RH piston is higher in the compression stroke when the center chamber opens and releases the compressed air from the LH cylinder and then the RH fires. IF the RH cyl is under higher pressure the air wouldn't leave the crossover tube. It's a neat idea I guess but I don't see it working as anything but a cartoon.
