I love all the possibility's.
'Engineering Explained' tackles Koenigsegg's camless engine

Very cool cam less video

Impressive. But until they increase their animation budget, they're still going to need to use cams for their videos.

LOL

I forgot the other video.

Interesting, they moved from pneumatic to electromagnetic, and that solenoid wire is a very reasonable size. I hope this is the solution we've been waiting for.

47% more torque
45% more horsepower
15% better fuel economy
35% less emissions

The part I'd like to see explained is using it for a compressed air pump for regeneration. That sounds like an end run around the Scuderi patent.

No pumping loses. When the Chinese actuators are on eBay, it will be possible to 3D print a VW 1600cc boxer head with a 4-valve hemi combustion chambers and a compressed air hybrid system. It would rev to 15,000rpm.

47% more torque is rather dishonest. They just turned the boost pressure up to get that.

A typical NA street engine with 1 cam profile produces something like 75Nm/L at 1500rpm, and around 100Nm/L in the midrange. With a big cam, you can get 120-130Nm/L at high speed, but that's it.

Ideal valve timing can get you maybe around 90Nm/L at low speed rather than 70-80, the same 120-130 at high speed, and maybe 110 in the midrange if the intake runners are tuned to work best there. The torque increase is more like maybe 3-5% peak, and 10-20% in "torque dip" regions. The torque increase over something with multiple cam profiles will be much smaller.

If these are commercialized and have reasonable power consumption that would be a dream come true. More power, more efficiency, less weight.

He also said in the video at on that redesigned cylinder head he was running 12:1 compression instead of the original 9:1, which would make substantially more torque as well... On an earlier video, he mentioned retrofitting a Saab 9-5, and gaining 20%, which sounds more reasonable... It sounds great, having a continuously variable valve opening profile...
