The “camless” engine is developed by Koenigsegg sister company FreeValve and is now close to production. Qoros, Chinese car brand, tried to conquer Europe’s market before but Europe wasn’t ready for them.
The brand is doing just fine in China using a 1.6 turbo, which has been developed by Germans a couple of years ago, but they want more. Koenigsegg’s Freevalve technology produces 47 percent more torque, 45 percent more power; it uses 15 percent less fuel and has 35 percent fewer emissions from an engine that’s lighter, smaller and cheaper to manufacture. A Chinese car is to be the first to get it.
The camless engine, which Qoros has labeled Qamfree, relies on pneumatic valve actuators to open an engine’s valves instead of a camshaft. Air pressure or springs then close those pneumatic actuators. This results in more precise and customizable control over valve duration and lift, on both the intake and exhaust sides.
According to the developers, the benefits are increased power and torque but when combined with downsized engines, you also get a reduced fuel consumption. The engine now don’t need parts like the throttle body, cam drive, camshaft, timing gear and cover, pre-catalytic converter systems direct injection systems and wastegate, to help in reducing the size, weight, and complexity.
The prototype is based on the automaker’s 3 compact hatchback and features a turbocharged 1.6-liter camless engine that allegedly to delivers 230 horsepower and 236 pound-feet of torque.
The Qoros 3 prototype features the first driveable version of FreeValve’s camless engine that has been designed with mass production in mind. FreeValve and Qoros plan to start testing a fleet of prototypes before moving to production. Unfortunately, no timeline has been given for when we might see this production model.
