"Your both right and your both wrong.
F1 tech is my domain haha, F1 engines DO use Hydraulic or Pnumatic (depending on the team) to close valves (a few years ago they did both) Under the hybrid era, Valves must be mechanically opened, but there pneumatically closed, so they can be closed faster and harder than a cam would allow, whats the point of all that boost and energy recovery when it all leaks by valves closing as is traditional with a normal cam shaft.
F1 get the best of both worlds, each system has its advantages and disadvantges.
If you do a bit of fishing online you can find photos of F1 engine camshafts, and you aint ever seen lobe profiles like it
On another note i saw a comment about laser ignition this is bollox, and a tech that will never make it, HCCI or Hermerogeneous Charge Compression and Ignition is a spark less way of ignighting fuel, sticking with F1, Merceidies and Ferrari and Honda all use HCCI at some level now mercedies is obviously the best it operates much better, if you listen to a MERC of the throttle in breaking zones and listen carefull you can hear the engines switching from SPARK to HCCI and vice versa, its even more apparant on the HONDA listen to that fucker of throttle sounds like the days of the blown diffusers HCCI is way superior to any other kind of ignition but its only recently the technology has been around that it can be done, for more than 40years HCCI has been on some form of bench.
For those who dont know HCCI is exactly the way Diesel Engines ignite or detonate there fuel, without a spark, just cold fuel into a red hot pocket of air and KABOOM, well petrol and other fuels can be ignighted this way aswell, only its not so simple.
These 2 together pneumatic valves and HCCI is estimated to be between 5 and 25% more efficent all around, more power less fuel, less nocking, less risk of detonation, relativly low cylinder pressures, lower stress on engine components in particular to the piston, where detonation no longer hppens over the pistons center to push down, but burns way more unitform pressing the WHOLE surface of the piston down.
I have no doubt the trolls will soon be here to abuse me so come and get it, ill see if i can find the photos for yall of the cam profiles, and the link to the HCCI information for you all"
