  1. rick bradner Says:

    cam-less engine?
    Didn’t Renault use similar tech on their F1 engines years ago? Pneumatically actuated me thinks…

  2. Kit Gerhart Says:

    I’m pretty sure F1 engines still use camshafts, but use pneumatic valve “springs,” rather than wire springs.

  3. Buzzerd Says:

    There sure are a lot of ideas on how to make the internal combustion engine better or more efficient yet almost none of them have made it to any kind of mass production.

  4. Albemarle Says:

    It’s all about the control you have over piston location & speed (Nissan variable stroke), combined direct and port injection and now camshaft free valves. Sure hope the car computer doesn’t need a reboot. It could mean a totally destroyed engine.

    On another topic, I wonder how Multimatic handles the heat issue of offroad vehicles. I understand F1 might have 2 inches of travel, but offroad can have over 12″. That’s a lot of friction heat to dissipate in a teeny tiny shock. Interesting to know how.

  5. Kit Gerhart Says:

    There are a number of techniques used to make IC engines more efficient, but in small increments. GDI, by most accounts, is worth about 3%. Atkinson Cycle tuning increases efficiency a few per cent, but works best for hybrids, because of the weak low rpm power. Then, there are small displacement turbos, that can give better mpg when driven gently, but little or no improvement, when driven normally.

    Just the basics of port injection with closed-loop control, made a bigger difference in power, emissions, and efficiency, than about anything that has come along since then. That, along with along with many-speed transmissions with tall top gears, have made today’s cars very efficient. The fleet average mpg keeps improving, in spite of the fleet becoming increasingly obese.

  6. Ziggy Says:

    I absolutely LOVE the concept of camless engines, the tuning possibilities are endless and sure to provide more power, torque, and fuel efficiency from the same displacement engine. I wish them the best and hope to see it on everyday vehicles in my lifetime. Too cool!

  7. Kit Gerhart Says:

    Camless engines would be cool, but they need to be very reliable. A software crash could cause a major valve/piston crash, like a broken timing belt on certain Honda, Ford and other engines.

  8. Bo Says:

    Your comment is on why BMW and Baidu are no longer working together is incorrect. The real reason is that BMW is joining forces with Mobileye and will be using cameras as primary sensor, given mobileye’s expertise in artificial intelligence, sensing and driving policy. Baidu uses a much more expensive sensor with less room to improve – lidar. The reason why companies that use lidar such as google and Baidu will eventually fail is because that lidar does not have the information density as cameras. In level 5 autonomy, the car needs to understand people’ s facial exporession and eye movement to estimate intent, lidar will never be able to do that. The reason people use lidar now is because it is easier to work with and you don’t need any expertise in image analysis. Mobileye will come out of this chaos as the eventual victor.

  9. Bo Says:

    BMW will be using Mobileye algorithms on an Intel chip and a Mobileye chip, along with Mobileye REM and driving policy algorithms. Baidu, Google are too far behind and of course will be abandoned by automakers.
