A camless or free-valve piston engine is an engine that has poppet valves operated by means of electromagnetic, hydraulic, or pneumatic [1] actuators instead of conventional cams. Actuators can be used to both open and close valves, or to open valves closed by springs or other means.

Feb 16, 2016 · The idea of a camless engine has been around forever and the big issue has always been finding an actuator system that is at least as reliable as cams, and reasonably simple.

Jan 28, 2025 · While most car engines have a camshaft, there are some cars with a camless engine. But what does this mean, and what benefits does this configuration offer?

Jan 14, 2016 · In theory, a camless engine can run on any combination of its cylinders, with conventional or the more efficient Atkinson and forced-induction Miller cycles (thanks to their relatively bigger...

Jul 1, 2020 · A camless engine is an engine employing poppet valves operated using electromagnetic, hydraulic, or pneumatic actuators instead of conventional cams. Further, actuators are used to both open and close valves, or to …

Oct 24, 2016 · In this episode of Engineering Explained, we get a deep-dive explanation of how Koenigsegg’s FreeValve camshaft-free engine works, as well as a look into its various benefits. This is the absolute bleeding edge of engine technology, and it could one day trickle down into the cars we drive every day.

Feb 26, 2014 · Why not go a little coo coo bananas and think of something bonkers? Something like compressed air. The Freevalve engine gets rid of the camshaft and the throttle body, replacing it with pneumatic...

Jun 24, 2023 · A camless engine is a type of internal combustion engine that uses electronic actuators to control the valves, rather than the traditional camshaft. These engines are called ME engines or Mechanical Electronic engines.

Oct 19, 2016 · By getting rid of camshaft and the throttle body, Koenigsegg says you get better power, torque, efficiency, fuel economy, and emissions. It's an engine that can run on multiple fuels, run as a...

Camless refers to a system or engine that eliminates the need for a mechanical connection between the camshaft and valve mechanism, instead using exhaust gas pressure or other means to actuate the valves.
