Gegenstand der Erfindung ist eine Kraftmaschinenanlage, welche aus einer Wärmekraftmaschine, in welcher die Gase nur durch Expansion wirken, mit einer von ihr unabhängig arbeitenden Explosionsmaschine kleineren Hubvolumens besteht, in welcher letzteren während eines Kolbenhubes der ersteren mehrere Ladungen und Zündungen stattfinden und welche ihre nach jeder ZündungThe subject matter of the invention is an engine system, which consists of a heat engine, in which the gases act only through expansion, with a smaller explosion machine that works independently of it Stroke volume exists, in which the latter during a piston stroke of the former several charges and ignitions take place and which one theirs after each ignition

ίο entstehenden Verbrennungsgase durch einen gesteuerten Verbindungskanal unmittelbar an die Wärmekraftmaschine abgibt, um in dieser allein oder nach Vereinigung mit etwa in ihr vorhandenen anderen Expansionsgasen Arbeit zu leisten. Diese letzteren können brennbare Gasluftgemische oder auch Dampi, Heißluft, Druckluft u. dgl. sein. Es können in die Wärmekraftmaschine auch flüssige Brennstoffe eingespritzt werden, die durch Berührung mit den Brenngasen der Explosionskraftmaschine entzündet werden.ίο resulting combustion gases through a controlled connection channel gives off directly to the heat engine in order to be in this alone or after combination with any other expansion gases present in it To do work. These latter can be flammable gas-air mixtures or also Dampi, Be hot air, compressed air and the like. It can also be liquid in the heat engine Fuels are injected through contact with the combustion gases of the explosion engine be ignited.

,Durch diese Art der Umsetzung' einer hohen Drehgeschwindigkeit in eine niedere wird das Drehmoment auf die Kurbel der Wärmekraftmaschine sehr günstig beeinflußt, und zwar um so günstiger, je größer das Umsetzungsverhältnis ist, so daß schließlich Wirkungen erzielt werden können, die denen eines Volldruckes beinahe gleichkommen."By this type of implementation" a high speed of rotation into a low one the torque on the crank of the heat engine is influenced very favorably, and the more favorable the greater the conversion ratio, so that ultimately Effects can be achieved that are almost equal to those of a full print.

Es ist zwar bereits bekannt, die Verbrennungsgase einer Explosionsmaschine in einem Sammelbehälter aufzuspeichern und mittels derselben eine zweite Maschine zu treiben.Although it is already known, the combustion gases of an explosion machine in one To store collecting containers and to drive a second machine by means of the same.

Da bei einer solchen Maschine alle Gasteilchen eine gewisse Zeit im Behälter verbleiben, so entsteht ein Wärmeverlust und damit auch ein starker Druckabfall der Gase.Since in such a machine all gas particles remain in the container for a certain time, this results in a loss of heat and thus a strong pressure drop in the gases.

Der Erfindung gemäß werden diese thermischen Verluste dadurch beseitigt, daß bei normalem Betrieb die Verbrennungsgase auf dem Wege von ihrer Erzeugungsstätte zur Wärmekraftmaschine keinen Aufenthalt erleiden. Nur für die Ingangsetzung der Wärmekraftmaschine, beim Betrieb von Bremsen, Signalen usw., kann ein ausschaltbarer Ausgleichsbehälter eingefügt werden.According to the invention, these thermal losses are eliminated in that at normal operation the combustion gases on the way from their place of production to Heat engine do not suffer a stay. Only for starting the heat engine, when operating the brakes, Signals etc., a switchable expansion tank can be inserted.

Sinngemäß wird als direkter Weg auch das bezeichnet, wenn etwa ein Sammelbehälter eingeschaltet werden sollte, der nur einer so beschränkten Anzahl von Ladungen Platz gewährt, daß die eintretenden Abgase im wesentlichen glatt durch ihn gehen, so daß im Sammelbehälter eine Aufenthaltsdauer nicht entsteht, sondern der Sammelbehälter der Hauptsache nach in Wirklichkeit einen mehr oder minder direkten Durchgang be-, deutet.This is also referred to as a direct route, for example when a collection container should be switched on, which can only accommodate such a limited number of charges allows the incoming exhaust gases to pass through it essentially smoothly, so that a length of stay does not arise in the collecting container, but the collecting container the main thing in reality is a more or less direct passage, indicates.

Wenn die Explosionsmaschine im Zweitakt arbeitet, kann der Übertritt der heißen Gase in die Wärmekraftmaschine in bekannter Weise durch eine Pumpe unterstützt werden, um eine Verschlechterung des Zündgemisches durch zurückbleibende Verbrennungsgase zu verhindern. Bei im Sechstakt arbeitenden Maschinen ist zwar die Pumpe schon in den Arbeitsphasen der Explosionsmaschine selbstIf the explosion machine works in two-stroke, the passage of the hot gases be supported in the heat engine in a known manner by a pump, to a deterioration of the ignition mixture by remaining combustion gases impede. In the case of machines working in six-stroke cycles, the pump is already in the Work phases of the explosion machine itself

Claims

given. However, it is also recommended for them as well as for those who work in four-stroke cycles Machines to switch on a pump to the ignition chamber of the explosion machine at the Definitely pure intake of new gas-air mixture.

In the drawing, an embodiment is illustrated in which the heat engine has two cylinders and with which the ignition of the gas-air mixture in the Explosion cylinder takes place in that the piston takes the gas-air mixture up to self-ignition condensed.

Fig. Ι represents a longitudinal section along the line I-II-III-IV of FIG. 2 and this itself a cross-section.

The piston b sucks in fresh gas-air mixture through the valve c into the cylinder α of the explosion machine and compresses it until it spontaneously ignites. The burning gases pass through the opening valve d and the Kanaiy which can be sealed off by the three-way valve e into the channel g of the control box h and from this in the position shown of the control piston i through the control cylinder k and the opening Z into the cylinder m of the heat engine, where they propel the piston η forward. Since the explosion machine makes so many revolutions compared to the heat engine that several ignitions of the former occur on one piston stroke of the latter, the combustion gases produced by repeated charges and ignitions must flow into the cylinder m until the piston η has reached its lowest position . When the piston η is in reverse, the control piston i removes the connection between the channel g and the cylinder in and the combustion gases

are driven out of the latter through openings I and 0. During this exhaust period, the expansion gases of the explosion machine enter the second cylinder p, namely, from the channel g into the control cylinder q and from there through the opening r. When the combustion gases are exhausted from cylinder p, which takes place through openings r and 0 , the game repeats itself again.

The control of the heat engine can be regulated in such a way that on a piston stroke the latter, any number of ignitions of the explosion machine are omitted.

The heat engine can also have only one cylinder, so that the combustion gases act on both sides of the piston. However, instead of one or two cylinders, several can be arranged so that the combustion gases are divided. The explosion machine can also work in such a way that it only emits its combustion gases to the heat engine on the return path of piston b, that is to say during its exhaust stroke.

The three-way valve e has the purpose of being able to shut off the heat engine from the explosion machine if necessary, with the exhaust gases being fed through the. Step 5 into the open air.

PateNT-AνSPRUcη:

Power plant, consisting of a heat engine and an as Gas generator serving explosion engine, characterized in that it is independent of the heat engine working, im. Stroke volume smaller explosion machine during one Piston stroke of the former causes several charges and ignitions and the combustion gases produced after each ignition through a controlled connection channel directly to the heat engine gives off in order to be in this alone or after association with any existing in it other expansion gases to do work.
