Thermodynamics

  PV-Diagram  

The internal combustion engine can be described thermodynamically. The PV-Diagram describes the Otto-engine and the JRS-Engine:

PV-Diagram

  Otto-engine  

The PV-Diagram distinguishes 3-cycle processes, namely:

  1. Theoretical process (BLUE, points: 20, 21, 24, 25 (surface-A)).
  2. Actual process (GREEN, points: 2, 3, 4, 5, 6, 7, 8, 9 (surface-B)).
  3. Pump-loss process (GREEN, points: 1, 2, 10 (surface-C)).

  JRS-Engine  

The PV-Diagram distinguishes 3-cycle processes, namely:

  1. Theoretical process (BLUE, points: 20, 22, 23, 18 (surface-A)).
  2. Actual process (RED, points: 12, 13, 14, 15, 16, 17, 18 (surface-B)).
  3. Pump-loss process (RED, points: 11, 12, 19 (surface-C)).

  Thermodynamic losses  

Optimal use is made of the power stroke (exhaust gases leave via the exhaust port under atmospheric pressure).

MAATREGEL 01

The fuel is injected directly into a large number of minuscule spherical combustion chambers making a very high compression ratio possible and the fuel auto-ignites.

Maatregel-02

Because of the large number of minuscule spherical combustion chambers, the heat supply and discharge occurs at an almost constant volume. In addition there are no short-circuit losses and an optimal mixture (homogeneous atomization λ = 1) is available at any time.

Maatregel-04

Thermal loss is limited by insulating the minuscule spherical combustion cores (hot-spots) with the help of surrounding air, thermal insulation of the engine and minimum internal turbulence.

Maatregel-07

In addition, the intake chamber does not come into contact with hot combustion gases, and in contrast to the rest of the engine, the chamber is not insulated but cooled. Consequently, the inlet gases remain cool and as a result of this the volumetric energy efficiency remains good and negative work is avoided.

Maatregel-08

The leakage losses are also kept to a minimum. As a result of this, the thermodynamic losses are minimal.

Pump losses are avoided because the output power control is not by choking the gases in the inlet duct but by varying the number of combustion chambers that are/are not directly injected.

Maatregel-13

In addition to this, there is an uninterrupted inflow and outflow (no valves, optimal duct shape, etc.) This comes close to achieving the theoretical ideal (inflow and outflow of gases at atmospheric pressure).

Maatregel-14

From the description above you can deduce that the concept is very likely to have minimal thermodynamic losses.
