i have one ambicious project of engine.
it's simple, but it's hard to do. i hope have money and everything works. finger crossed !!!

i promise you'll be seeing these soon , GM already tried to steal the design from the guys who originally designed it. an since they patented it so well that now GM, ford an chrysler are already talking with the designers to put some of these into their production cars... there just waiting to see who they sell to first (gotta sell to the highest bidder) plus they already had this engine running (its went over a million miles an no major problems) but they are leaning more towards diesel
i dont understand ...( 3 months ago by fmftrx300ex)
i dont understand where the efficience comes from? it just seems like it would creat more heat and drag and rotating mass, thus less proformance? anyone explain?
Just to set the ...( 3 months ago by engineguy32)
Just to set the record straight...
1) Nobody has tried to steal this design, although Scuderi wishes they would. Willful patent infringement = triple damages.
2) The engine has been built (e.g., someone posted a video of one youtube). But, it has not yet been put in a car. It will be running on the dyno at SwRI relatively soon.
3) You are correct that there is actual interest from major OEMs.
4) You are correct that the engine is likely to be better utilized in diesel applications.
If by "worse" you ...( 3 months ago by engineguy32)
If by "worse" you mean less efficient, then right on.
Rotaries do have advantages, such as their compact size. If I remember correctly the RX-7 had a 1.3 liter engine producing something like 300bhp.
Saw the design on ...( 3 months ago by shinejunkie73)
Saw the design on the Engine Expo. It seems as if the firing after top dead center eliminates the issue of compressing the gas twice. I guess that if they can make this thing run as they promise at a 30% reduction in fuel we might see them in cars someday..... Heat issue seems to be solved as the engineer told me. The only extraordinary about it is that they need to use synthetic lubricates and air actuated valves.

i guess i phrased it incorrectly , they "WANTED" the design but after finding out they couldn't since they had it patented it so well.
also I know the engine has been built , ive seen it myself.
the blue cyliner ...( 2 months ago by qwwqqe)
the blue cyliner acts like a compressor, then the power cylider acts like that of a two stroke engine.. so my question is.. would all those valves be controlled by means of a cam?
i dont know if this really is efficient in power-to-weight ratio..
This seems to be a ...( 2 months ago by Moknabt)
This seems to be a remake of an old design, with the air tank added. Theoretically it might be of some use though. The liquid makes more whirlpools as passes through, which humbles injection power slightly, but migth yield better results in vaporization, decreasing the fuel consumption. But various calculations should be made to see if the energie gained by beter vaporization compensates for the energy lost in the increased friction. Plus timing will be more crucial than in the Otto engines...

The basic design ...( 2 months ago by LifesVoyager)
The basic design dates back to the 1930s - I have rebuilt a 2 stroke version myself.
The regenerative part is interesting but dubious.
Pretty graphics - now build one and prove it works. Money where your mouth is.
The basic design is ...( 1 month ago by engineguy32)
The basic design is a split-cycle engine that fires after TDC. Why don't YOU put your money where your mouth is and show us such a design from the 1930s.

that seems odd that only the big 3 american automakers are trying to 'steal' this. It just sounds like a lot of speculation to me. the thing about this engine is- its 2cylinders doing 2 strokes each 2x2=4 this is the same as 1 cylinder doing 4 strokes 1x4=4. that fact that it is double the parts and transfering fluids around, there is no way it is as efficient as a 4stroke or diesel for that matter. just because they have a patent doesnt mean they have a great product.

you are saying the prius is equivalent to a 3.6L six? the prius is slow as hell even with ultra light weight aluminum engine and other parts. I can pull a very long lever and produce more torque than that with my pinky finger it doesnt mean a thing.

the engine doesnt do what it says it can do. if it could there would be proof, not just hype by the 'inventor'. if anyone says otherwise, be prepared to back it up

its not how many strokes , its how it burns the fuel.

This is not a bad ...( 1 month ago by warmingtone)
This is not a bad design, it uses a lot of the time the engine isn't being worked to store the compression in air that can be used to move the cylinders. No outrageous claims really, it is an engine and compressor. Would be complex to get the timing and controls, but at least they didn't claim "over-unity" or anything silly!
It is similar to the older opposing cylinder engine used in ships and trains way back, but for the added compressor and storage which is significant. Thanks.
Exactly. Prior ...( 3 weeks ago by engineguy32)
Exactly. Prior split-cycle designs did not fire after TDC (or far enough after TDC) to realize the projected gains. The air-hybrid feature is completely new in a split-cycle arrangement.
