Synison Laboratory has developed an innovative transmission mechanism known as the Distributive Oscillating Transmission (DOT) that interconnects multiple coaxially rotating elements, optimizing mechanical efficiency for various applications, including advanced internal combustion and hybrid engines. The technology allows for programmable angular velocities and can perform complex thermodynamic cycles with high efficiency. The laboratory seeks licensing, technical cooperation, and manufacturing partners in relevant industries to commercialize the mechanism and its applications.

Title:
Transmission Mechanism interconnecting in the most effective way a number of coaxially rotating Elements with a Shaft, and
Advanced Internal Combustion Engine, Hybrid Engine and Stirling Engine as its major Applications
Abstract:
A Hellenic (Greek) Laboratory, highly specialized in Pure Mechanical Systems, has developed an Innovative Transmission Mechanism
with many significant Applications and is looking for license agreement and/or technical cooperation agreement and/or Partners involved in
the production of the Mechanism and/or its Applications.
This Transmission Mechanism (DOT: Distributive Oscillating Transmission) interconnects, in the most effective way, a plurality of
Elements with a main Shaft, said Elements and Shaft rotating coaxially around a common axis with different but completely programmable
angular velocities.
This interconnection is achieved via planetary systems with some non-circular gears which have almost the same mechanical efficiency as
the standard ones.
The aforementioned Transmission Mechanism can perform literally any desired Cycle, Thermodynamic or not, even one with odd
number of asymmetrical strokes, with the greatest possible degree of mechanical efficiency in both directions.
One major application of this Transmission Mechanism is an Advanced Internal Combustion Engine (THE: Toroidal Hermetic Engine) with
Three Rotating Toroidal Pistons, performing in the simplest possible way an almost Ideal Thermodynamic Cycle:
- Intake (of pure air-fuel mixture or mixed with exhaust gas, if necessary),
- Compression (up to any desired Compression Ratio),
- Combustion (Isochoric, for any desired Period, almost exactly or exactly, if necessary),
- Expansion (for any desired Period, with Volume, continuously, up to any desired multiple of Intake Volume),
- Exhaust (down to any desired Volume, even zero Volume, if necessary),
- MetaStathmeusis (with/without cooling/cleaning procedure, for any desired Period, or even zero Period, if necessary).
From another point of view, this Internal Combustion Engine could be the main and the most adaptive Platform for a Compact Hybrid
Engine.
Other applications are Hydraulic Pumps or Motors, Pneumatic Pumps or Motors, Refrigeration Machines, Stirling Engines and Electric
Generators or Motors.
Main Innovative Aspects, concerning the Mechanism and its Applications, are:
- Innovative interconnecting Transmission Mechanism performing any desired Kinematic Cycle,
- Innovative Internal Combustion Engine performing an almost ideal Thermodynamic Cycle,
- Innovative Stirling Engine of high Thermal Efficiency.
Following a specific Research Strategy, more than Twenty substantial Parameters (some of them with a number of discrete values greater
than two) have been investigated, therefore more than Two Millions of discrete Structural Combinations have been virtually tested one by
one.
Among these Structural Combinations there are configurations without peripheral slot, or with shorter or even of zero length cantilever of the
body of the Pistons, or with a ratio of working volume to total toroidal volume much greater than the one that appears in this Proposal.
Although the configuration of this Proposal has performed very well in all the aforementioned virtual tests, there are other configurations
perhaps much more promising from a practical point of view and the exhaustive investigation of the commercial potential of all
these could be the subject of another Project.
There are already Two International Patent Applications (WO/2007/125373 & WO/2009/040588) with excellent Search Reports and Pending
Patents.
Significant Advantages, concerning the Mechanism and its Applications, are:
- Maximum Mechanical Efficiency (deviation of degree of efficiency of non-circular gears from the one of standard gears less than 0.1%),
- Maximum Robustness (all bodies are freely supported at both ends and all toothings are or can be strictly planar),
- Maximum Compactness (ratio of working volume to total toroidal volume up to nine to ten - not for the Engines of the Application Examples
of both International Applications),
- Achievement of any desired Progressiveness,
- Capability of Stop-and-Start Operation,
- Capability of Very Slow Output without an additional Reduction Unit,
- Achievement of excellent Sealing,
- Capability of Isochoric Combustion,
- Capability of Isobaric Combustion.
