Cam-Less engine link to story.
Here is something for all you super tech engine guys. I did not know this was coming. Maybe you did. Something else to go wacky with vacuum leaks (IMG:style_emoticons/default/blink.gif) |

They've been working on it for a few years. I remember they had a test mule based on a Saab motor back then.
I love the idea of no need for direct injection while still improving performance and mpg (no more carbon buildup issues or need to run a catch can). Kudus to the Chinese manufacturer for funding a real production engine. Hope they don't 'take' the tech like some of their other industries do. Watch the koenigsegg series on the /Drive channel on YouTube...amazing things going on there! |

Here is a link to info at R&T, for those of us who want to avoid a fox site. (IMG:style_emoticons/default/bye1.gif)

Neat concept, now lets see if that circuit board with connectors can handle all the heat cycles and oil....and yea...air leaks.

B&W/MAN in Denmark were working on this for marine diesel engines,hydraulic actuation was there setup never heard of an end result but they had an engine on a test bed for a long time and it ran fine years ago, but I did wonder what would happen if it stopped and the oil supply shutdown,tech wouldn't tell me cause it was very secret @ the time. |

It's been on the way for a long time now. If Konigsegg really has the bugs ironed out enough for a production engine, that would be very cool.

Apparently, the pneumatic actuation is incredibly noisy compared to mechanically operated valves. I haven't reviewed the new tech described here, I assume they've figured out a way to get round the problem. It would be a gigantic leap forward if it could be made to work quietly, reliably, and efficiently. |

I was in a tech school probably 6 years ago where a friend was teaching advanced secondary BMW mechanics. He showed me a cylinder head that had solenoids over the valves in place of the cam. I seem to recall it was some sort of prototype.

I thought this was already a reality in F1 with the solenoid valves? Or this: Rotary valves |

They've been using pneumatic return springs for years. http://www.formula1-dictionary.net/pneumat..._actuation.html https://www.reddit.com/r/formula1/comments/...nary_camshafts/ Info in the 2nd URL is 2 years old, but I think the rules are still the same. |
