hey guy's, don't know if anyones seen this yet, but this guy's building some seriously amazing engines. Their currently going into production in other country's, and he started building them in his garage at home.
He claims they never need an oil change because they only have 2 moving parts. Check out that valve system
Check out some of the video for interviews etc.

Putting lube shops outta business in the future

 

I think we're all thinking the same two things...

1) can I get one for a honda?
2) how the ---- am I gonna turbo that ******?

 

seems like a decent idea, but using un-lubricated bearings is excessive - why use exotic materials when they arn't really needed? i guess it's for bragging rights.
i recall reading about a company making flat-4 engines whose crank looked like a pair of rotors from an RX-7, rotating in opposite directions. the pistons of opposite cylinders were tied directly together by the connecting rod - it's just a solid beam. the beam/pistons would ride on a pair of rollers around the perimeter of the two crank rotors. the result was the same reciprocating motion you get in todays engines, but it doesn't have to fight the side to side forces created by a typical crankshaft/connecting rod combo. it's like having the ultimate rod/stroke ratio.

 

old news, technology came out around 2000

 

those engines not going to work

 

They do work, but I think the only real benefit is you nolonger have reciprocating valves that can interfere with the piston

 

they might have the engine of the future but they've go the website of the late 1980's

 

Why the ---- would you bump a 5 year old thread?

 

because earlier the old posts were at the top and he probably didnt realize
