Description
Die Erfindung betrifft eine Verbrennungskraftmaschine mit innerer Verbrennung, bei der durch verschiedene technische Maßnahmen thermische Verluste verringert werden.The The invention relates to an internal combustion engine, in the case of thermal losses due to various technical measures be reduced.
Stand der Technik ist, dass bei Verbrennungskraftmotoren mit innerer Verbrennung, also in der Regel bei Otto-, Diesel- oder Rotationskolbenmotoren (z. B. Wankelmotor), ein großer Teil der eingesetzten Energie durch das Abgas oder das Kühlsystem in die Umgebungsluft gelangt und nicht in mechanische Energie umgesetzt wird. Es wird versucht mittels Turbolader, die im Abgas gespeicherte Energie, in den Motor zurückzuführen. Das funktioniert nur zum Teil, denn unterschiedlichste Verluste führen dazu, dass nur ein geringer Prozentsatz zurückgeführt werden kann.was standing the technique is that in internal combustion engines with internal combustion, So usually in gasoline, diesel or rotary piston engines (eg Wankel engine), a big one Part of the energy used by the exhaust gas or the cooling system gets into the ambient air and not converted into mechanical energy becomes. It is tried by means of turbocharger, the stored in the exhaust Energy, due to the engine. The works only partially, because different losses lead to that only a small percentage can be reduced.
Die ins Kühlsystem eingebrachte Energie wird in aller Regel maximal zur Erwärmung des Fahrzeuginnenraumes genutzt (im Winter).The into the cooling system introduced energy is usually maximum for heating the Vehicle interior used (in winter).
Strahlungsverluste des Motors und des Abgasstranges müssen sogar mit technischen Maßnahmen von der Karosserie abgeschirmt werden.radiation losses of the engine and the exhaust line must even with technical activities be shielded from the body.
Wir sind also vom Idealfall, einem Motor, bzw. Abgasstrang ohne nennenswerte Wärmeverluste noch sehr weit entfernt.We are therefore of the ideal case, an engine, or exhaust system without significant heat loss still very far away.
Der Erfindung liegt die Aufgabe zu Grunde, diese Wärmeverluste durch verschiedene technische Maßnahmen zu minimieren.Of the Invention is the object of this heat losses through various technical measures to minimize.
Begriffsdefinition:Definition of terms:
Im folgenden werden Kompressions-, Expansions- und Brennraum definiert als „mit Brenngasen beaufschlagter Raum" (immer kursiv geschrieben). Beim Hubkolbenmotor wird dieser Raum durch die Zylinderwände, den Zylinderkopf und durch die Oberseite des Kolbens eingeschlossen und begrenzt. Beim Rotationskolbenmotor wird dieser Raum durch die Innenflächen des den Rotationskolben umgebenden Gehäuses gebildet, also durch die Kammervolumina, auch durch die Kammer, in der Frischgas verdichtet wird.in the following are defined compression, expansion and combustion chamber as with Fuel gas charged space "(always written in italics). When Hubkolbenmotor this space is through the Cylinder walls, enclosed the cylinder head and through the top of the piston and limited. In the rotary engine, this space is through the inner surfaces of the housing surrounding the rotary piston, that is, through the chamber volumes, also through the chamber, in which fresh gas is compressed.
Ferner wird im folgenden das den mit Brenngasen beaufschlagten Raum umgebende und durch die Außenfläche des Motors eingeschlossene Volumen „Umgebungsraum" (immer kursiv) genannt.Further In the following, it will be the surrounding space occupied by fuel gases and through the outer surface of the Motors enclosed volume called "environment space" (always italics).
Die den mit Brenngasen beaufschlagten Raum umgebende Wand/Oberfläche wird ganz oder teilweise mit einer Schicht ausgestattet, die es ermöglicht den Durchlass von Strahlungsenergie zu verändern (z. B. photoelektrisch, durch Schichten mit Flüssigkristallen, ähnlich der Gläser in automatisch abblendenden Schweißhelmen).The becomes the wall / surface surrounding fuel gas completely or partially equipped with a layer that allows the Passage of radiant energy (e.g., photoelectrically, by layers of liquid crystals, similar to the glasses in automatically dimming welding helmets).
Die Wand zwischen dem mit Brenngasen beaufschlagten Raum und dem Umgebungsraum wird ganz oder teilweise transparent ausgebildet und mit eben genannter Schicht ausgestattet.The Wall between the space occupied by fuel gases and the surrounding space is formed completely or partially transparent and just mentioned Layer equipped.
Zwischen dem mit Brenngasen beaufschlagten Raum und dem Umgebungsraum erfolgt eine gesteuerte/geregelte Energieübertragung. Das heißt, Wärmeenergie gelangt durch eine Wand mit steuerbarer Energiedurchlässigkeit vom mit Brenngasen beaufschlagten Raum in den Umgebungsraum und umgekehrt (je nach Temperaturgefälle).Between takes place the acted upon with fuel gases space and the surrounding space a controlled / regulated energy transfer. That is, heat energy passes through a wall with controllable energy transmission from the charged with fuel gases space in the surrounding space and vice versa (depending on temperature gradient).
Der Umgebungsraum ist mit einem Material hoher Wärmeleitfähigkeit und hoher Wärmespeicherkapazität gefüllt.Of the Environmental space is filled with a material of high thermal conductivity and high heat storage capacity.
Die den Umgebungsraum umgebenden Wände können isoliert ausgebildet werden, damit der Motor nach außen möglichst wenig Wärme abgibt.The surrounding the surrounding space walls can be formed isolated, so that the engine to the outside as possible little heat emits.
Die eben aufgezählten Lösungen dienen dazu, eine Verbrennungskraftmaschine zu bauen, die trotz geringer Wärmeabgabe nach außen (aus dem Umgebungsraum in den Motorraum oder das Motorumfeld) einen ausgeglichenen Wärmehaushalt aufweist. Die mit Brenngasen in Kontakt stehenden Flächen können gezielt, insbesondere an kritischen Stellen, gekühlt oder beheizt werden. Die im Abgas enthaltene Wärmeenergie wird teilweise in den Kompressions- und Expansionsraum oder die Arbeitskammer zurückgeleitet, ohne dabei den Wirkungsgrad durch Erwärmen der Ansaugluft oder des Kraftstoff-Luft-Gemisches zu verringern. Die Luft/das Gemisch wird also erst nach Eintritt in den Kompressionsraum mit Wärme beaufschlagt, somit werden der Liefergrad (Füllgrad) und die Temperatur des Gemisches vor der Verbrennung nicht negativ beeinflusst.The just listed solutions serve to build an internal combustion engine that despite low heat emission outward (from the ambient space in the engine compartment or the engine environment) a has balanced heat balance. The surfaces in contact with fuel gases can be targeted, in particular at critical points, cooled or heated. The heat energy contained in the exhaust gas is partially in the compression and expansion space or the working chamber returned, without affecting the efficiency by heating the intake air or the Reduce fuel-air mixture. The air / mixture becomes So only after entering the compression chamber with heat applied, thus the degree of delivery (degree of filling) and the temperature of the mixture before combustion is not negative affected.
