i have great ideas all the time but let me know what you think of this--the valves use push rods WHY with the tec we have now i think the push rods and timeing belts--chains ect are a thing of the past--WE HAVE SERVO MOTORS,yes very small and powerfull servos -brushless servos- wireless servos--all we need is a transmiter on the crank and a reciver in the wireless servo--there thats it--WHAT YOU THINK

 

 

Not a bad idea... Less moving parts, cam chain tensioner problem solved, less weight, more precise control, and easily tunable via computer. Not sure why nobody has tried it yet...

 

Wonders how they would react in such heat?

 

I thought of this long ago, and thought about how many times those servos would have to work, on fails, and you could drop a valve into a piston, but if you could get a servo that wouldn't fail after millions of cycles you would be on to something.

 

+ 67wizard What you been smokin????????

 

Formula 1 engines use actuators on their valves. I believe they are pneumatic, and those engines turn 10,000+ rpms. Of course, the only have to last for one race before the engine is torn down.

 

Why not a Solid State Electric switch controlling a Fast acting Electric Acuator? Change lift and duration of your valves with your computer.

 

Someone (Saab, I think) has been experimenting with a cam-less engine for quite some time. The thinking is that with a simple software change you can have either a fire-breathing performance motor or a mild-mannered economy motor. The cost is, of course, astronomical.

 

Lots of possibilities. Solenoid/servo operated valves that don't need springs. Valves that are entirely outside the combustion cylinder so they eliminate the possibility of valve/piston contact. Rotary valves, etc. All it takes is a good idea, time & money.
