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!

Hmm interesting

the future is here, and it kinda scares me

hear xD

Just another thing to go wrong…

People back in the 80’s said the exact same thing about EFI. Now it’s been in almost every vehicle for the last 20 years and has even been improved with Direct Injection. With Koenigsegg backing this kinda tech I wouldn’t expect it to be made terribly either. Christian von Koenigsegg said himself in a past video that they’ve been running it reliably for years in a test mule Saab.

But what about when you overheat the engine, the rail heats up, the gasket or circuit board cracks and you get oil in the electronics? Not sure how I feel about it, but I’m curious to see what they do with the idea.

Someone doing one of the most sophisticated cars on the market would probably have come up with a solution and proper materials choice.. probably.

well the problem is in your question. If the engine overheats you already have a problem.

Repost! Used the search feature… That’s one reason you created it for!

Yes. But I think it is in CT’s interest to post stuff like this. Anyway, this so damn awesome.

i was wondering when will someone replace gears with electronics.
this looks good but if electronics fail, there goes the engine

Not necessarily. The engine will simply run in fail safe mode allowing it to run on other 3 cylinders.

whata time to be alive

WEVE LANDED ON THE MOON!

they have been using a similar system on commercial diesel ship engines. it operates off fuel pressure from the boosters, or hydraulic pressure from a system driven by the crankshaft. this technology has been around a very long time.
