Development of a more efficient and reliable axial engine?

Sorry couldn't get the editor to work. can someone embed?
 
Just saw this on fb. pretty cool stuff. Less spark plugs with same output as a v6. Wonder how durable this type of motor is.

yeah I was wondering how the wear on the cam and the whole rotating piece would be in the long run. Similar to like an how apex seals on a rotary blow under more power.
 
Very cool. I really wonder how it will hold up over time.

How is it lubricated though?
 
How quick does it go through headgaskets? I feel like it's a cool concept, but the center rotating thing is just going to go wrong.
 
Pretty cool, heres another new technology being developed by Koenigsesggisgesggisgigs with a camless engine. I could listen to this guy talk about everything, there's a great series on their development of the Agera R also
 
Axial engines aren't anything new, and I don't think they will be a thing of the future because of the difficulties involved with sealing a head and block that slide against eachother. Axial pumps however are used pretty frequently in a number things though, so I guess some form of success has come from this concept of engine.

I think that's a cool technology but what happens when the electric motor that drives the valve burns out? IDK I feel like it is dangerous to rely on electricity to control the valve timing of a high performance motor. Obviously they are an innovative company (there's an awesome piece about how they make their carbon fiber wheels) but feel this type of technology is risky. I'm sure I'm wrong.

There isn't a motor, the valves are opened by a pneumatic system which is controlled by solenoids, and then closed by spring pressure like any other engine. It's kind of similar to electronic fuel injection. If the solenoids failed, the valves being under spring pressure should just close which wouldn't be the end of the world on an engine with multiple valves; the engine computer could likely compensate by closing other valves and then enter some form of limp mode.

Currently, any kind of combustion engine that is considered an interference engine (valves and piston move into the same space, but not at the same time) would be far more likely to have major damage done in the event of a snapped timing belt or chain. So really, if that cam-less engine could default to valves closed in a failure it would be far better off than most modern engines.
