No it’s just a four stroke triple with pneumatic valves and no camshaft
Simples, like you Al

[Alan H]

But it's how the pneumatic actuators are controlled and the options of control with AI.
Much like you Paul.

But it’s still uses valve’s which makes it a four stroke
Oh I don’t have any form of intelligence, artificial or otherwise

[Alan H]

Never thought of rotary valves then Paul?
Or intelligence then?
Try it, even fish have some, which makes them hard to catch so anglers call it sport.......
Better to go shooting and work out shot speed against bird flight speed and 'lead' so you actually shoot the gits.
Worms can't do that with fish when they've a hook up their arse.

[PaulD738]

Rotary or disc valves aren’t located in the cylinder head which would make it a four stroke

[750ynot]

Could be called a 5 stroke due to the miller cycle

But certainly not a 2 stroke Alan

I just googled it, interesting read the both of them.

Bet that sounds

[Alan H]

Their designation, not mine. As is your link.
But using turbo(s) to clear residuals out of the cylinder does make it possible to run with a firing sequence every rotation on lower power requirements.
