Abstract

The steam engine supplies vaporising energy to water under high pressure. The vaporising energy is composed of remaining energy of the steam engine and that of an extra electric heating. The latter is automatically generated by the engine. The heated water is injected through valves (7) located in covers (8) of an empty sealed chamber (10) to generate steam pressure in the chamber. The remaining steam is removed from the cylinder (11) through an auxiliary valves (9) in the covers (8). Electric energy is generated by coils (12) in the cylinder due to resulting motion of permanent magnets (14) on the piston (13). Energy is generated in the middle and at the ends of the cylinder (11) and distributed. ADVANTAGE - Efficient energy conversion system.

Description

Aus dem Zweitakt- und dem Freikolbenmotor ist der Zweitakt- Freiflug-Dampfmotor entwickelt. Seine erhebliche Restenergie (1) wird im Wärmetauscher (2) und Kondensator (3) vom Dampf zum Wasser (5) zurückgeführt. Die Pumpe (4) bringt das Wasser (5) auf einen höheren Druck, als im Verdichterraum (10) erforderlich ist. Damit kann im Vorwärmer (6) vor dem Einspritzventil (7) die Verdampfungsenergie dem Wasser (5) zugeführt werden. In den Zylinderdeckeln (8) befinden sich die Einspritzventile (7) und die Spülventile (9). Diese und die Dampfaustrittsschlitze in der Zylinderwand (11) sind für den Energieumlauf erforderlich. Die Spülventile (9) ermöglichen einen drucklosen Verdichterraum (10). Der Zylinder (11) ist aus Keramik, so dotiert, daß die auf dem Kolben (13) befindlichen Dauermagneten (14) den Kolben (13) in der Schwebe halten. Im Zylinder (11) befinden sich die Wicklungen (12), getrennt in Leistungs- und Heizungsenergie. Hier wird die elektrische Energie erzeugt.The two-stroke free-flight steam engine was developed from the two-stroke and the free-piston engine. Its considerable residual energy ( 1 ) is returned from the steam to the water ( 5 ) in the heat exchanger ( 2 ) and condenser ( 3 ). The pump ( 4 ) brings the water ( 5 ) to a higher pressure than is required in the compressor chamber ( 10 ). This allows the evaporation energy to be supplied to the water ( 5 ) in the preheater ( 6 ) upstream of the injection valve ( 7 ). In the cylinder covers (8) are the injection valves (7) and the purge valves (9). These and the steam outlet slots in the cylinder wall ( 11 ) are required for the energy circulation. The flushing valves ( 9 ) enable an unpressurized compressor chamber ( 10 ). The cylinder (11) is doped ceramic so that the permanent magnet (14) located on the piston (13) hold the piston (13) in the balance. The windings ( 12 ) are located in the cylinder ( 11 ), separated into power and heating energy. This is where the electrical energy is generated.

An den Zylinderdeckeln (8) und den Kolbenböden des Freikolbens (13) sorgen Dauermagneten dafür, daß der Aufprall des Freikolbens (13) auf die Zylinderdeckel (8) verhindert wird. Die auf dem Freikolben (13) ringförmig angeordneten Dauermagneten (14) sind auch für die Stromerzeugung erforderlich, die aus den ruhenden Wicklungen (12) problemlos abgeleitet werden kann. Permanent magnets on the cylinder covers ( 8 ) and the piston heads of the free piston ( 13 ) ensure that the free piston ( 13 ) does not collide with the cylinder cover ( 8 ). The permanent magnets ( 14 ) arranged in a ring on the free piston ( 13 ) are also required for the generation of electricity, which can be easily derived from the stationary windings ( 12 ).

Leistungpower

In Fig. 2 ist die Kraft durch Leistungsdiagramme mit 25% und 45% dargestellt. Die Dampftafel gibt v′/dcm³ und v′′/m³ an. Für den Dampfmotor sind v′/cm³ und v′′/dcm³ angenommen. Da beide im Verhältnis 1/1000 stehen, werden 1 cm³ Wasser zu 0,1 dcm³ Dampf bei einem Druck von 15 bar. Somit 2,5 und 4,5 cm³ Wasser, zu 25 und 45% Dampf, bei einem Hubvolumen von 1 dcm³ des Dampfmotors.In Fig. 2, the force is represented by performance diagrams with 25% and 45%. The steam table indicates v ′ / dcm³ and v ′ ′ / m³. V ′ / cm³ and v ′ ′ / dcm³ are assumed for the steam engine. Since the ratio is 1/1000, 1 cm³ water becomes 0.1 dcm³ steam at a pressure of 15 bar. So 2.5 and 4.5 cm³ of water, 25 and 45% steam, with a stroke volume of 1 dcm³ of the steam engine.

Auf Blatt (3) sind in zwei Beispielen aus diesen Diagrammen die Abläufe der Energieumwandlung dargestellt.On sheet (3) are two examples from these diagrams the processes of energy conversion are shown.

Hierbei sind die erforderlichen Energien für den Enddruck (vd), durch die daraus entstandenen Pi, mit den im Vorwärmer (Pv) zugeführten Energien ins Verhältnis gebracht. Die Vorwärmeenergie (Pv) wird dadurch in Kw ausgedrückt.Here are the energies required for the final pressure (vd), through the resulting pi, with those in the preheater (Pv) energies brought into relation. The Preheat energy (Pv) is expressed in Kw.

Die zur Verfügung stehende Überschußenergie (Pe) wird damit:The available excess energy (P e ) is:

Pe = (Pi-Pv) × µi × µm = KwP e = (Pi-Pv) × µ i × µ m = Kw
