Check out the "FreeValve"

That's cool!

I've always wondered when someone would incorporate electric selenoids that were strong enough,
and lasted long enough to be used for actuating/controlling valves in an internal combustion engine.

Cat has been working that for diesel over 10 yrs ago.

Block with no head and electric actuated valves to go with the electric injector.

I can think of 32 reasons why I wouldn't want it!

Formula one has been doing this for a while.

Camless engines are already on the market, the dodge/fiat 1.4L multiair has no intake camshaft but does have exhaust.

Hi Guys

A Sottish guy called Dugald Clerk invented The camless engine (https://en.wikipedia.org/wiki/Two-stroke_engine) in 1881 about the same time as the gunfight at the O.K Corral

They've already got their WIKI entry:

Camless development

Camless engines are not without their problems though.
Common problems include high power consumption, accuracy at high speed, temperature sensitivity, weight and packaging issues, high noise, high cost,
and unsafe operation in case of electrical problems.

Camless valve trains have long been investigated by several companies, including Renault, BMW, Fiat, Valeo, General Motors, Ricardo, Lotus Engineering, Ford, Gongda, and Koenigsegg's subsidiary FreeValve.
Camless systems are commercially available, although not yet in production road vehicle engines.

In the spring of 2015 Christian von Koenigsegg told reporters that the technology pursued by his company is "getting ready for fruition", but said nothing specific about the time-table.
