  Mechanism  

The mechanism (see the diagrams below) comprises a housing (red) with a chamber (red) containing a rotor (blue) which has a number of vanes (green) extending in a radial direction toward the wall of the chamber, which separate the chamber into a number of compartments, where each of the compartments is meant to carry out at least one of the following functions:

1. The intake and/or compression of the gas needed for combustion;
2. Igniting the fuel;
3. Delivering the power;
4. Exhausting the combustion gases,

where the first pair of vanes have a rotating attachment to a first rotation shaft, and where a second pair of vanes has a rotating attachment to a second rotation shaft, these rotation shafts being installed in the chamber excentrically.

Below is a brief description of the various phases of the working cycle, with an interval of 60-Degrees of rotor rotation:

  0-Degrees:  

1. Combustion occurs on 1-Side of the rotor.

  60-Degrees:  

1. Power is delivered (area in dark red hatching);
2. Exhaust gases from a previous combustion are expelled (area in light red hatching);
3. Fresh air is drawn in and the compression begins (area in dark blue hatching).

  120-Degrees:  

1. Power is still being delivered (area in dark red hatching);
2. Exhaust gases from a previous combustion are still being expelled (area in light red hatching);
3. Fresh air is drawn in (area in light blue hatching);
4. Fresh air is compressed (area in dark blue hatching).

  180-Degrees:  

1. Combustion occurs on the other side of the rotor.

  240-Degrees:  

1. Power is delivered (area in dark red hatching);
2. Exhaust gases from a previous combustion are expelled (area in light red hatching);
3. Fresh air is drawn in (area in light blue hatching).

  300-Degrees:  

1. Power is still being delivered (area in dark red hatching);
2. Exhaust gases from a previous combustion are still being expelled (area in light red hatching);
3. Fresh air is drawn in (area in light blue hatching);
4. Fresh air is compressed (area in dark blue hatching).

  360-Degrees = 0-Degrees:  

1. The rotor is back in its starting position.

  Mechanical losses  

The JRS-Engine has been simple from its basic concept and comprises few parts. It does not required additional components for, for example, gas exchange (no inlet and outlet valves and associated secondary systems), etc. In addition there is no need to develop very complex (secondary) systems, such as, for example:

1. Electromagnetic valve control,
2. Variable compression ratio,
3. Variable expansion factor,
4. Valvetronic,
5. HCCI,
6. Downsizing,
7. Etc.

This is because the basic concept for the JRS-Engine is closer to the theoretical ideal. In addition, it has simpler secondary systems:

1. Air cooling, so no radiator and water pump, etc.
2. A simple and light exhaust system (the exhaust port opens at atmospheric pressure, no damper is required).

The components of the JRS-Engine are light also and suffer almost no acceleration or retardation (at a constant engine speed). This results in low internal forces and vibrations.

Durable coatings with a low coefficient of friction are used. In addition, the concept lends itself admirably to the use of gas for lubrication and controlled sealing.
