Abstract

The set for the charge air and that for the exhaust utilisation are coupled to the engine power take-off. To the combustion chamber crank drive (1) are coupled one or two piston crank drives (2, 3). In case of two piston crank drives, one sucks fresh air and expels it twice, while the other one twice expands and expels the exhaust during the engine cycle. In the case of one piston crank drive sucks and expels fresh air out and once expands and expels the exhaust during the engine cycle. The coupling duct from charger to combustion chamber contains a charge air buffer and coder (10). The duct from combustion chamber to exhaust processor comprises a thermally insulated exhaust overflow duct (14) and a buffer (15).

Description

Die bessere Ausnutzung des Heiz- und Brennwertes des Kraftstoffes ist gleichzeitig mit der Verbesserung des Wirkungsgrades, d. h. der Aufladung, der Verbrennung selbst, der Verbrennungsgüte und der Abgasverwertung und schließlich die Reduzierung aller Reibungsverluste.The better use of the heating and calorific value of the fuel is at the same time as the improvement efficiency, d. H. the charging, the combustion itself, the combustion quality and the Exhaust gas recycling and finally the reduction of all friction losses.

Bekannte Verfahren, die dies verfolgen, sind Verbundverfahren, die den Turbolader, den Verbrennungsmotor und die Abgasturbine miteinander auf einen Abtriebsstrang kuppeln. In der deutschen Zeitschrift MTZ, Jahrgang 21, Heft 1, Januar 1960, Seite 8, sind mit einem derartigen Verfahren für hochaufgeladene Viertakt-Dieselmotoren erhöhte Wirkungsgrade nachgewiesen. Die Ladung stellt sich so besser bedarfsgerecht ein und vor allem das aufgestaute Abgas wird wie Treibgas in nachgeschalteten Turbinen je nach Anfall verwendet.Known methods that pursue this are composite methods that the turbocharger, the internal combustion engine and couple the exhaust gas turbine to one another on a drive train. In the German magazine MTZ, Volume 21, Issue 1, January 1960, page 8, are using such a method for highly charged Four-stroke diesel engines demonstrated increased efficiency. The cargo turns out better as required, and above all the pent-up exhaust gas becomes like propellant gas in downstream turbines used after seizure.

Dagegen sind die heute üblich freilaufenden, nicht am Abtrieb gekuppelten Abgasturbolader nicht als Verbundanlagen zu verstehen, da diese immer mit der Ladeleistung im Gleichgewicht stehen und nach außen keine Nutzleistung abgeben, denn die Ladeleistung ist von Abgasanfall und vom optimalen Betriebspunkt der Turbine abhängig, da so, entweder zuviel als auch zu wenig Ladeleistung zur Verfügung stehen kann, bzw. Leistungsvermögen verlorengeht.On the other hand, the exhaust gas turbochargers that are currently free-running and are not coupled to the output are not as Compound systems to understand, as these are always in balance with the charging performance and after Do not give any useful power on the outside, because the charging power depends on the amount of exhaust gas and the optimum Depending on the operating point of the turbine, either too much or too little charging power is available can stand or performance is lost.

Mit der Hochaufladung allgemein sind derzeit für Dieselmotoren, allerdings nur in bestimmten Betriebspunkten, thermische Wirkungsgrade bis zu 70% möglich. Die Spitzen der Leistungssteigerung bzw. Drehmomentensteigerung im praktischen Hochaufladebetrieb betragen dementsprechend 100%.With the supercharging in general are currently for diesel engines, but only in certain Operating points, thermal efficiencies up to 70% possible. The peaks of performance increase or Torque increase in practical high-charge operation is accordingly 100%.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die einzeln gewonnenen Ergebnisse konsequent konstruktiv in ein geeignetes Verbundsystem umzugestalten. Durchgehend soll über den gesamten Arbeitsbereich mit einem noch höheren Wirkungsgrad eine folgliche Kraftstoffeinsparung entstehen und eine weitere erhebliche Leistungsausbeute, sowie eine verbesserte Motorcharakteristik herbeigeführt werden. The invention specified in claim 1 is based on the problem, the individually obtained Constructively transforming results into a suitable composite system. Throughout should the entire work area with an even higher efficiency, a consequent fuel saving arise and a further significant power yield, as well as an improved engine characteristics be brought about.  

Dieses Problem wird durch die im Patentanspruch 1 ausgeführten Merkmale gelöst.This problem is solved by the features set out in claim 1.

Die erzielten Vorteile bestehen insbesondere darin, daß auf vorhandene Motoren aufgebaut werden kann und somit erhebliche Entwicklungskosten eingespart werden können. Lediglich der Zylinderkopf und das Steuerregime der Ventile muß geändert werden, bzw. in einer weiteren Ausführung ist zusätzlich der Kolbendurchmesser zu verändern.The advantages achieved are, in particular, that existing motors can be built on and thus considerable development costs can be saved. Only the cylinder head and that Control regimes of the valves must be changed, or in a further version, the Change piston diameter.

Die Frischluftladung mit Kolben (analog Kolbenkompressor) ermöglicht über den gesamten Drehzahlbereich die proportionale und nach oben max. mögliche Verdichtung der Ladeluft und auch deren Kühlung.Fresh air charging with pistons (analogous to piston compressors) enables the entire speed range the proportional and upwards max. possible compression of the charge air and also its cooling.

Das noch reichlich energiehaltige Abgas, das von dem nachgeordneten Kolben verarbeitet wird, ist bis zum Abfall auf den atmosphärischen Zustand nutzbar, bzw. Restverbrennungen aus dem Hauptbrennraum können noch zusätzlich von diesem übernommen werden.The still abundant energy-containing exhaust gas, which is processed by the downstream piston, is up to Waste can be used to the atmospheric state, or residual burns from the main combustion chamber can also be taken over by this.

Der Vergleich der thermischen Wirkungsgrade zum o. g. Stand ergibt am dargestellten Beispiel die Steigerung auf 84%.The comparison of the thermal efficiencies to the above. In the example shown, the stand gives the Increase to 84%.

Ebenfalls ist gemäß dem Beispiel, der dargelegten Verbundeinheit mit einem Arbeitvolumen von 0,3 bis 0,4 Liter, bei einer Motordrehzahl von 4000 min-1 eine Leistungsausbeute von 45 bis 60 kW (∼60 bis 80 PS) machbar.Likewise, according to the example, the composite unit shown with a working volume of 0.3 to 0.4 liters, at an engine speed of 4000 min -1, a power yield of 45 to 60 kW (∼60 to 80 hp) is feasible.

Das belegt den möglichen Einsatz der neuen Verbundanlage insbesondere in kleinen Dieselmotoren, für die bisher noch kein effektives Ladeverfahren bestand. Damit ist auch die Grundlage für ein Sparauto mit dem niedrigsten Verbrauch gelegt.This proves the possible use of the new composite system, especially in small diesel engines for which So far there has been no effective charging process. This is also the basis for an economy car with the lowest consumption.

Eine weitere vorteilhafte Ausgestaltung ist, daß die Frischluftladung und die Abgasverarbeitung nur von einem einzigen aber kombinierten Kolben übernommen werden kann (Fig. 3 u. 4).A further advantageous embodiment is that the fresh air charge and the exhaust gas processing can only be carried out by a single but combined piston ( FIGS. 3 and 4).

Die Umweltfreundlichkeit zeichnet sich bei etwa 25% niedrigerem konstruktiven Bauaufwand (kg/kW), besonders durch den geringeren Kraftstoffverbrauch, eine vollkommenere Verbrennung und geringerer Hinterlassung von Verbrennungsrückständen (CO₂, CO, NOx, CxHx) aus.The environmental friendliness is characterized by approximately 25% lower construction costs (kg / kW), especially by the lower fuel consumption, more perfect combustion and less residue from combustion residues (CO₂, CO, NO x , C x H x ).
