Abstract

The internal combustion motor assembly has a hot air motor coupled to the exhaust, powered by the hot exhaust gas. The motor converts the exhaust heat into mechanical energy, to increase the power output from the motor. The two motors can be coupled together without a mechanical clutch, with a controlled mechanical clutch or gearing between their drive shafts, or by a non-contact transmission between their drive shafts.

Description

Das hier angemeldete Prinzip beruht auf dem Umstand, dass marktübliche Verbrennungsmotoren bei einem Einsatz von 100% Energie - so z. B. in Form von Dieselkraftstoffen, Benzinen oder Gasen - nur etwa 30% bis 40% herkömmlich verwertbarer Energie abgeben. Damit ist das Verhältnis zwischen zugeführter Energie und genutzter Energie, also der Wirkungsgrad solcher Motoren, als noch immer dürftig zu bezeichnen. The principle registered here is based on the fact that it is customary in the market Internal combustion engines using 100% energy - such as B. in the form of diesel fuels, Petrol or gases - only about 30% to 40% of conventionally usable energy submit. So that is the relationship between supplied energy and used energy, so the efficiency of such engines can still be described as poor.

Die hier angestrebte technische Lösung nutzt die Tatsache, dass ca. 60% bis 70% der dem Motor zugeführten Energie in Form von Wärme verloren gehen. Daran ist der Abgaswärmeverlust mit etwa 30% beteiligt. The technical solution sought here uses the fact that approx. 60% to 70% of the energy supplied to the motor is lost in the form of heat. That's the one Exhaust heat loss involved with about 30%.

Dieser Abgaswärmeverlust beinhaltet gleichzeitig ein Optimierungspotential das, entsprechend des hier beschriebenen Prinzips eingesetzt, den Wirkungsgrad von Verbrennungsmotoren um 8% bis 10% anhebt, wobei die Abgaswärme des Verbrennungsmotors direkt einem Heissluftmotor zugeführt wird und dieser seine durch die Abgaswärme gewonnene mechanische Energie dem Verbrennungsmotor zuführt so dass Insgesamt eine um die oben genannte Größenordnung höhere Energie von diesen so gekoppelten Motoren abgegeben werden kann. This exhaust gas heat loss also contains an optimization potential that used according to the principle described here, the efficiency of Internal combustion engines increases by 8% to 10%, the exhaust heat of the Combustion engine is fed directly to a hot air engine and this through the Mechanical energy gained from exhaust gas heat is fed to the internal combustion engine so that All in all a higher energy of the order of the above coupled motors can be delivered.

Da der Heissluftmotor ausschließlich durch Abgaswärmezufuhr betrieben wird treten keine zusätzlichen Emissionen auf. Fehlende explosionsartige Vorgänge im Heissluftmotor gewährleisten wenig Lärm und Erschütterungen und erlauben in kompakter Bauweise die direkte Übertragung der gewonnenen Energie auf den Verbrennungsmotor. Since the hot-air engine is operated exclusively by supplying exhaust gas heat, none occur additional emissions. Missing explosive processes in the hot air motor ensure little noise and vibrations and allow the in a compact design direct transfer of the energy obtained to the internal combustion engine.

Die Zuführung der durch Abgaswärme des Verbrennungsmotors über den Heissluftmotor gewonnene Energie an den Verbrennungsmotor geschieht mittels Kopplungsverfahren und kann form- oder kraftschlüssig erfolgen, wobei natürlich auch beim Heissluftmotor Energieverluste auftreten die für die eigentliche Nutzung verloren gehen. The supply of the exhaust gas heat from the internal combustion engine via the hot air engine Energy gained to the internal combustion engine is done by means of coupling processes and can be positive or non-positive, and of course also with the hot air motor Energy losses occur that are lost for the actual use.

Insgesamt jedoch kommt es durch die Kopplung und Ergänzung beider Motorsysteme zu einer Wirkungsgradsteigerung, die nach Abzug der Energieverluste und Zugrundelegung des realen Wirkungsgrades eine Leistungsverbesserung von 8%-10% bedeutet. Overall, however, the coupling and expansion of both motor systems is required an increase in efficiency, after deducting the energy losses and using the real efficiency means a performance improvement of 8% -10%.
