SPRINGLESS Valve Control
Thank
you for taking a look at our innovative engine. A single cylinder working prototype
exists. Its patented cycle works well with either a spring managed valve including
a simple means of variable valve timing by non-cyclical adjustment of the valve
retrieval spring, as shown in the www.limtechnology.com
web site, or may work even better with a Pneumodromic valve, as explained above.In
our SCDi
engines,
exhaust leaves via the ports around the girth of the cylinder. Air for
combustion and incidental cooling is admitted through the patented valves,
spring or Pneumodromic, at the top of the cylinder.Cylinder pressure is
ample to keep the valves closed during compression and combustion; Pressure
in the input manifold is greater than that of the cylinder only when the
exhaust ports are exposed, allowing exhaust to escape; the valves are
opened by air pressure, which is always accumulating in the input manifold
when the valves are closed. Physical work leading to this concept began
in 1999; two US patents have been issued, and more applied for. International
patents are pending, nearly everywhere. Existing prototypes and tests
confirm the feasibility of both our original valve designs and the SCDi
engine.

Although, in the animation, we show a mechanical system for timing valve retrieval, we plan to experiment with an electronically managed electro-magnetic system so that a micro-processor could manage the valve timing with great precision.
