@@AJTalks Time. Even at a lowly 7000 rpm that's 58 times per second per valve. Distance. Cam lobes have ramps for a reason. You can not expect performance or reliability from an on/off linear motion. So now more time is required. Resolution. Camshafts are designed in .25 degree increments. Whilst this system wouldn't require that level of resolution you should be able to see how distance over time with performance and reliability is a problem that has not been overcome.
I think when the Freevalve technology become viable, it will revolutionize the automotive industry, since with that tech the companies can achieve numbers that with current technology is impossible, like over 50% thermal efficiency numbers, ultra low fuel consumption, very high rpms, very high compression ratio, higher turbocharger pressure, etc. And is a engine that can change its character with just the press of a button, so in the Eco mode the engine would be extremely fuel efficient, while in sport mode the engine would be extremely powerful. It's amazing! This tech would open so many possibilities that I can think about them all the day!😆

Can't wait to see the cost and maintenance bills. Also the pros they bought are vs a normal non vvt vvl or vc engines the last one of those stored being made 2006ish.
Valeo's electromagnetic valve control system is simpler and more reliable than any other, but the reason for not investing in the solution is the old co2 lie.
"All action has an equal and opposite reaction" - Sir Issac Newton. I other words; Electronic servos that have to fight springs have only transferred friction from the camshaft to the alternator and the larger heavier battery that they require.
You can change pressure with rpm to help lower that but the real issue is seal life and cost. They can't make them last a season in racing with unlimited budgets and no material out of budget. Now take your avrage Karen geting a oil change ever 10-20k miles
let's say 6000rpm = 1ms needed for open/close operation. magnetic field saturation after electricity for solenoid is turned on is not instantaneous and probably requires more time than 1 ms.
@@Dalehogg89 How many car engines do you know of that can run at 10000 rpm? And how high does the average driver go? Id say most driver rarely go over 4k
I first saw this in 1980,but back then they used 2 solenoids per valve so valve springs where very weak, just enough strength to keep the valves closed when all power is off. Much better system with much better control, it was bulky and expensive, roll forwards 44 years and the technology is a fair bit cheaper
I want to use this onmy Pulse Jet Engines.Just match it to the pipe length.140hz on my RC 10kg thrust PJ.No more reed valve fails & more thrust.Then I can build 30 in a cluster & go drag racing.
Free Valve should just be pneumatic ran of a supercharger creating a vacuum in the exhaust manifold of the active valve to evacuate the burnt gases and create a partial vacuum for the inlet valve was opened. As it is off a low pressure Supercharger it would not need to be large, heavy or powerful! It is not as if it was forcing induction. Just purely waste removal.
I dont believe in such technologie , it is very less durable and to me as more electronic parts the more bad a engine will be to failures , so NO NO , not for me
Had this similar idea 20 years ago. Nice to see someone implementing it.

@@jdoe9518 What limitations are there on solenoids? They have quick working time and can be water cooled.

Except that there are already engines without Throttle bodies using variable timing and lift making this just unwanted complication
@@mydroidid and they use another intermediary shaft + a motor "phasing" it and all the valvetrain which is a "unwanted complication"
@@mydroididyou can squeeze out more efficiency with It though
😂
You must not know much about engines if you believe this is revolutionary or would make engines 50% more thermally efficient
Hilarious how this guy pronounces pneumatic. Love it.

This technology eliminates so many moving parts and friction .

probably the electronic parts have to be replaced every two rides

Saying "ICE engine" is like saying "ATM machine".
PIN number.
Correct me if I’m wrong - but I have a memory of reading that Mercedes had electric valves on a V12 -? This was around 2005 as I remember it.
Not electric valves. Just VVT.
Lets move onto the durability , reliablety 😂
Why use air and not a big electric solenoid?

@@royroye1643 at 10k rpm your valves open and close every 12 seconds. not sure where you get 1ms
@Ckcdillpickle every 12ms at 10000rpm. That's 1000X faster than your comment dude

Where is this "technology" today if it is so great? It works great in a cad program only. Not in the real world.

Opposite piston engine already achieve 50 percent plus thermal efficiently. Free valve is just gloryfy pneumatic with stupid price tag

Add capacitors to each valve don't be a dinkray
I have not much faith in this system unless you do this. And I AM A MANDRILL
Things move way too fast !!!!!
