The Elio Engine

[Kuda]

Well, maybe.
It would eliminate the camshaft and associated parts including the 2 step lifter (which I'm not thrilled about) and decrease the overall size and weight. I would also allow a 4 cyl version to fit relatively easy (for you torque heads out there)

The (truly) variable timing would increase MPG up to 30%. a 90-95 MPG Elio would be an even easier sell.

Granted, this technology should wait until initial production in 201X.

I did tweet the 'Camless' tech. ) to
IAV , makes way to much sense
for the elio motor but those pesky
patents do get in the way...

Has Paul said anything about the possibility of the engine being manufactured and made separate from the car? I recall some months back where all sorts of applications were suggested, from mini-delivery vans to boat engines to lightweight aircraft engines.

Yes, there is another company that has been given the rights to manufacture the engine, I don't recall their name at the moment, but I sure someone else will

That sounds right

This technology will work it's way down to the echono boxes, the same way the automated manual transmission has. Once the cost of development is paid for by the high dollar players.

Not sure if posted yet. Too lazy to search.

Free Valve camless head. Eliminates cam shaft and timing belt and allows valve optimization for all modes

additional information. I really like this idea!

Nice find. I've seen valve-free designs as well. One had a cam that looked like it had balls instead of lobes but the balls had slots in the right places to allow in air or fuel. It wasn't as flexible as the Koenig but still pretty cool.

I think you'll see camless engines hit the mainstream for diesels first. It's just the RPM range they have to operate in is more limited as opposed to a gasoline. At this point, the main issue with most ICE's has been efficiency. The efficiency numbers get better but by baby steps. Direct injection has pretty much been the efficiency gainer for engines as of recent and mixing that with a low pressure turbo ends up being the best you can get right now. That's why it's getting harder and harder to find engines that are not direct injection plus normally aspirated. They just can't get the numbers (fuel consumption and performance). Most of this technology has been driven by the Europeans and Japan because they have a much more aggressive requirement over the next 10 years when it comes to efficiency and emissions as compared to the US.

I like that the cam-less version that Koenig uses has pneumatically controlled valves instead of electronically controlled valves that I've seen elsewhere. Of course, they still have an electronic solenoid to control the air flow.

Question: Are they planning on an interference motor or are they looking at non-interference designs? If it is an interference engine, well, I've had a couple of solenoids go out on me which caused power issues but if a valve actuator dies while the valve is extended or fires really late, the piston will eat a valve and THAT isn't just a cheap solenoid swap!

Off subject, but here's the worst alt-fuel setup I've ever seen...

Yup... that's pretty bad. LOL
