Check this out. A Chinese carmaker, Qoros, has joined Koenigsegg in showing a camless engine. Instead of the traditional camshaft controlling the engine’s valves, the QamFree motor uses electro-hydraulic-pneumatic actuators. This supposedly adds power while improving fuel economy by 12 to 17 percent.
Rather than continuing to use this technology, which Koenigsegg likens to “playing a piano with a both hands tied to the opposite ends of a broomstick,” the QamFree engine allows far greater control over the engine’s intake and exhaust valves thanks to electro-hydraulic-pneumatic actuators.
Unfortunately this concept cam-free engine doesn’t have a release date.
