Electronic valve actuators
Electronic valve actuators
(OP)
We want to build a prototype engine for development purposes while providing maximum control over intake and exhaust valve timing. It would seem that electronic intake and exhaust valve actuators would provide maximum flexbility.
We are looking for suppliers of actuators and electronic controls for intake and exhaust valves, preferrably as a complete kit. However, we woul settle for the electonic control module and electronic actuators, and integrate the system from there.
We be grateful for any leads you may provide or other advice.

Thank you.
I'll contact FEV to see where they stand.
I'm gathering from your replies that electronically controlled valves might still be primarily in the realm of R&D. For a prototype we could consider a technology in it's latter stages of development, but would seek an alternative approach rather than lumber our project with a early-stage technology.
Our application is relatively low speed 300-1000 rpm and stationary, so we might be able to live with a few bug.
Will keep looking for a while and see what we turn up.

Tom

Googling electronic valve timing got some hits like

A Prof/engineering student project here

Wiki has some variable valve timing material here

Interesting topic.
RE: Electronic valve actuators
Excellent links! They provide lots of great info to follow up on.
Looks simple enough. We might well try it in our prototype. The benefits of EVT seem worth pursuing. Our engine cycle could significantly benefit from this technology.
My colleague is a EE, so I'll turn over the electronic valve timing and engine controls to him. ;)
Thank you,
Tom

One company that tried & failed to develop such a system was AURA. Here's a link:

Thanks for the link.
Our primary focus is engine development and, if it's not too difficult to implement EVT on the test stand, we'd prefer to have full control over valve timing instead of grinding a bunch of cams. And while were at it, if we like what we see with EVT, maybe we proceed with that approach instead of cams. Efficiency is a top priority in our project.
Best regards,
Tom

Valeo is working to adapt the Renault Formula 1 derived Electromagnetic Valve Actuation technology for commercial application. Perhaps you can source the needed hardware through them.

I'm sensing it may be worthwhile to dabble with EVT as it appears to be a quickly emerging technology and we'll be that much further along to implement it having monkeyed with it a bit.

I was told that SAGEM worked with Renault to develop that system for F1 application, during one of my visits to Pontoise in late 98. I saw some physical hardware while I was there, and it looked amazingly like the pictures they have now released ot the public. I was only told of the F1 link up. I don't know if it ever made it into a race engine, or was killed off during development. I suspect that it was originally started a a research project for F1, but as engine RPM kept advancing in the 90's, it probably became obsolete before it was raced, if it ever was raced.

Then there's the weight of the system- wouldn't multiple solenoids outweigh a conventional system ??
