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!

Personally I think this is the best innovation that could be done to an internal combustion engine. Engineers are trying to get rid of camshafts for decades, because they limit engine’s performance so much…even with variable timing and lift. This looks brilliantly simple compared to the existing variable timing and lift products. Needless to say it can be controlled with better accuracy at any rpm.
Can’t wait to see all manufacturers adopt the system!

not to forget that you do not need a throttle body anymore. No more loses in air intake!

Imagine this used in a rally where how much fuel you consumed was factored in.

I wish you realised how dangerous it is to have no mechanical connection between pistons and valves… you could very easily make them coincide in space and time, and we all know what that leads to. Admittedly here in case of a fault the valve would just not open, but it still feels a bit like playing with a naked ass in front of a hard c*ck…

Only if the design is so that the pistons and valves can clash. Perhaps it’s a valid safety measure to make sure it doesn’t. There are quite a few engines where it’s actually impossible.

It’s amazing how something controlled and monitored by computers is called “FREEVALVE”.

Slavevalve would fit it better 😂

This makes me proud of being a swedish petrolhead. :)

First not convinced … then studied it a bit more .. yeah this is the future. Super.

Dear Santa, i’ve been dreaming about this for years! No more timing belt as well! Please bring us universal camless conversion kits and megasquirt 4 with individual valve control!!

One crankshaft sensor malfunction and all that beaufiful tech gets crunched by the pistons. :D

Where the pistons kick the valve’s ass outta exaust

Not if the valve gets neatly pushed up by the piston. That failure mechanism should be designed out if the valves are electro actuated.

well unless the sensor is going to give wrong but also correct values (which isn’t very likely to happen). It wil go into safe mode in which the engine probably will not run/ stop running. Anyway it isn’t going to be pretty with today’s engines either (ie. all the vvt). No crankshaftsensor no gogo
