    How can a famed automotive nation responsible for creating iconic brands like Saab and Volvo possibly add to the industry? Well, one company plans to produce a radical new engine.

    Swedish company FreeValve AB is re-working the internal combustion engine by removing crucial parts, claiming fuel savings of near 20 per cent.

    The FreeValve concept, also known as fully variable valve actuation, offers independent control of the intake and exhaust valves – doing away completely with the camshaft, hence the term ‘camless’.

    The company’s innovative design, placing electronic connectors between the rails and actuators, mean the system is able to ‘decide’ what air/fuel mixture is needed in response to driving conditions.

    Valves are opened by hydraulic-pneumatic actuators and closed by spring or compressed air. This system is controlled with advanced sensors to control timing and lift – allowing the controller to know the valve position to within 1/10 of a millimeter in real time.

    FreeValve have already tested this technology on the road with results showing a verified fuel consumption reduction of 12 – 17 per cent compared with traditional direct injection and variable cams – significant performance improvements have also been achieved.

    Although you may not have heard the name FreeValve before, you could be more familiar with their Chief Executive Officer, Christian von Koenigsegg – founder of the Swedish supercar maker Koenigsegg. FreeValve are a subsidiary to the exotic car maker and the success of their development program could see the technology make its way into the supercar market.

    In April this year, FreeValve AB also announced a partnership with Qoros Autos, a Chinese car maker. The partnership opens another avenue for the company to take their working concept and transfer technology to a production application for passenger vehicles.

    Christen von Koenigsegg stating; “We believe that one day in the very near future, the arrival of FreeValve PHEA technology will represent as big a transition, or bigger, than the move from carburetors to direct injection.”

    It remains to be seen if technology like FreeValve can save the internal combustion engine from the surging wave of electric technology filling the automotive sector. Regardless, innovation is still ongoing, even Mercedes-Benz has announced new petrol engines.

    It will be interesting to see if camless engines make their way to the showroom floors of New Zealand.

    I’m thinking new motorcycle technologies here too. It used to be that bike makers led technology and licenced it to car makers: the Yamaha/Toyota tech foir instance. Nowdays it seems the car industry is leading the bike industry. I’m imagining a 500cc twin cylinder turbo bike motor with both these technologies making 150hp with torque like a 1200 vee twin and weighing around 150kg (dreaming?)

    This is halfway there, and from Suzuki no less.
