Koenigsegg have Introduced a Camshaft-less Engine!

  • Koenigsegg’s sister company, Freevalve, has come out with a technology that removes the traditional CAM drive.
  • They have replaced the Cam mechanism with electro pneumatic actuators.
  • The advantages are humongous. Weight savings and infinte variable valve timing possibilities are more than enough for this being a seller.
  • The cam-less engine from FreeValve is major step towards Innovative valve control system .
  • The tech will roll onto the stage in the 1.6-liter turbocharged engine in a specially modified Qoros 3 hatchback. According to FreeValve, the powerplant produces 230 horsepower (172 kilowatts) and 236 pound-feet (320 Newton-meters) of torque.
  • The figures reportedly equate to 47 percent more power, 45 percent more torque, and 15 percent better fuel economy than the same powerplant with a conventional valvetrain.
  • The reason we have a four-valve cylinder head instead of a two-valve is so it can breathe freely on high rpm for more power, but that’s counteracting your efforts at low rpm, because you get less speed through bigger ports and less turbulence and poorer distribution.
  • This move closer to mass production of FreeValve technology is also a first baby step towards the promise of important reductions in CO2 emissions.
  • An engine with it would have infinitely variable valve timing, including being able to completely shut them for cylinder deactivation. The system also means that the engine doesn’t need any traditional timing gear and can even do away with part like the throttle body, wastegate, and direct injection systems.
  • The changes free up a claimed 44 pounds (20 kilograms) off a powerplant and make it smaller by removing so many components.
