Brief Description of THE DOT (CHI Phase)

Innovative Transmission Mechanism (DOT: Distributive Oscillating Transmission) that 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

The aforementioned interconnection is achieved via Planetary Systems with some Non-Circular Gears which have almost the same mechanical efficiency as the Standard ones

This 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 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, the aforementioned 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 of THE DOT (CHI Phase)

Innovative Interconnecting Transmission Mechanism performing Any Desired Kinematic Cycle

Innovative Internal Combustion Engine performing an almost Ideal Thermodynamic Cycle

Innovative Stirling Engine with High Thermal Efficiency and the most possible Simplicity

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 longer or 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
