Here's How Koenigsegg's Fascinating Camless 'Freevalve' Engine Works
This interesting video has surfaced explaining in more detail how the innovative Freevalve engines work. It gives the car full individual control of each intake and exhaust valve, allowing individual timings to increase performance or minimise fuel consumption
This is not a new video, but it appears to have been picked up by MotorAuthority yesterday and is now doing the rounds. It’s a fascinating watch that we haven’t shared before, so here you go!

When you look at the lengths people have gone to and the variety of Variable Cam Timing (VANOS/VTEC) systems that have been used it is no surprise that this was the ultimate end goal.
My only concern with this type of valve is that by being dependent of an electrical system, if any sensor fails or voltage drops below ability to function the valve there isn’t a failsafe for interference. I’m sure someone will figure it out but for now I’ll stick with oil pressure driven variable timeing thank you very much.
Nissan had VVEL first
Here is a great video from the guys over at /Drive where the man himself and an employee explains how it works. https://www.youtube.com/watch?v=Bch5B23_pu0
Looks to me like Formula 1 tech, F1 uses pneumatic valves since the 90’s to achieve 20k rpms.
Sorry this is off topic but I need assistance from a Moderator if possible. Here’s an awesome car picture as recompense for my unwelcome intrusion
can someone explain the difference between this and bmw’s valvetronic to me? I remember someone saying that valvetronic is something sounding very similar
i always Wonderd why we never used solenoids in the head
dope!
No gearbox in a car then this?!?! Maybe Mr. Koenigsegg is from the future like Dr. Wells (thawne) in The Flash?!?!
Next thing I want to see squashed, now that timing belts are gone and cars will last longer without needing major surgery: alternator belts and such.
Let’s make cars more reliable, so that we can drive around in rallies and whatever for years upon years without problem. 24 hour endurance races without a single engine failure? Fascinating.
Make races more fair… Less DNFs by mechanical malfunctions.
