Koenigsegg Cam-Less Engine
The cam-less engine from FreeValve, a sister corporation of Koenigsegg, will prove that the technology works by driving onto the stage during Qoros’ presentation at the Guangzhou Motor Show in November 2016. It’ll be a major step towards the innovative valve-control system actually going into production.
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.
“This move closer to mass production of FreeValve technology is also a first baby step towards the promise of important reductions in CO2 emissions,” said FreeValve Chairman Christian von Koenigsegg.
The video below offers a brief explanation of how the tech works. Rather than conventional rockers and camshafts, there are pneumatic-hydraulic-electronic actuators controlling the valves. FreeValve claims the results are revolutionary. 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.
Before the cam-less engine can actually go on sale, there’s still more testing to do. Qoros and FreeValve will now start evaluating it in fleets of vehicles, and they’ll be edging closer to actually putting an engine with this tech on sale.
FreeValve has been working on its cam-less engine since 2000. In 2012, the company even reportedly developed a prototype version using Koenigsegg’s biturbo V8. The company also displayed a concept of the system with Qoros at Auto China earlier this year.
