The ultimate hybrid engine..this is a must read

[Guest Anonymous]

I may be behind. Everyone may already know about this, but for everyone else who doesnt you must visit this site www.oxtwo.com/ Carrol Shelby is backing this new engine (among many other greats) I found this by accident while looking for engine stuff for my 78 280z v8. Imagine the power of a v8, almost zero emissions, immediate power, 140 lb engine, and no bigger than half a keg of beer. This is just incredible reading. I think it would benefit everyone here to read this. How about some feedback. Thanks. Kevin the highpsiguy@aol.com

There was another place that had a new head design -- it was cam-less. Or, rather, the cams and the valves were one and the same. The cam shafts were actually a couple inches in diameter, and instead of pushing on valve stems, they actually had openings going right through them. One 'cam' would do the intake, having openings at each cylinder that would rotate into the correct position at the appropriate time in the firing cycle. Of course there would be a separate such 'cam' for the exhaust. These 'cam's rode on some special ceramic bearings that needed no oil.. so.. the benefits:

No valves, no pushrods, no rockers, NO OIL IN THE HEAD, less oil needed for the engine, capability of huge intake and exhaust openings, so potentially gobs more power.

Overall this is supposed to be MUCH more efficient than current setups.

All of this new technology doesn't replace your existing engine; it just replaces the heads and intake.

One of the writeups on their site said they took a mustang or something and basically doubled the horsepower (or something like that. It was amazing, whatever it was.)

 

I wish I could remember the name of the company.. I know they were mentioned here a few months ago... Anyone remember?

 

Apparently they're not only planning on selling complete engines, but they're going to do conversion kits for existing motors... which I guess include their special rotary / camless heads and intake..? I wrote to them asking if they had a kit for a sbc350, but they said not yet. Very cool stuff though! I can't wait to see this stuff in action. Hope they can get this stuff to market.

Coates Engineering was the name of the company that was developing rotary valves. There is a thread on them titled "Rotary Valves" in the High tech forum.

 

I really hope to see stuff like this come into the industry soon... Its pretty amazing that engines still use 115 year old technolgy! (well, not quite, but close)

 

Also the OX2 engine was discussed in the high-tech forum, under the title "A new type of 8 cyl engine...". But if you have something to add, please add away!

There is another company working on this technology,, they have been testing at pikes peak. Called simply "Camless technology" I think thier method is computer controled solonoid operated valves. They started primarily with deisel engines, and morphed into high performance applications. This isnt a head and intake upgrade, I believe it is a completely redesigned engine format. But dont quote me on that, I am lookin for more info . Tony

OK: It is Intrenational who is building this engine and I was wrong, it is computer controlled , hydrolicly operated valves. this is supposed to make for an almost 0 emissions engine and along with the "green deisel tecnology" become the powerplant of the future. Hummmmmm we will see. Tony

Cool looking hybrid engine, this looks very much like a engine I saw of all places in a model airplane magazine. It was a rotary design similar to the OX engine but in scale model size (and was commercially available for model airplanes), this could have been a early design of this group, not sure.

As far as camless designs, years (and years) ago I believe MIT was playing with a chevy that used solenoids above each valve and controlled the whole thing by computer (crank triggered). While the longetivity of solenoids might be questionable, consider the implecations. Variable cam timing (and I'm not talking just a wee bit like the manufacturers like Honda and the rest have pursued but total control over valve operation, from stock to race cam all done up in a map with the fuel injection and timing following suit...). Some questioned Hot Rodding in the 21st century, hey, its just getting good!
