Das Anlassen und Auftemperaturbringen des Motors geschieht folgendermaßen:The engine is started and heated up as follows:
Das Aufladeaggregat wird angelassen und zum selbstständigen Arbeiten gebracht; der Motor wird angeworfen, wobei ein Verteilungsorgan betätigt wird. welches dem Motor wenigstens einen Teil der von dem Lader gelieferten Luft über die zu dem Kühler parallel geschaltete Abzweigleitung zuführt. Diese Betätigung des Verteilungsorgans wird aufrechterhalten, bis die Temperatur der Flüssigkeit des Kühlkreises einen solchen Wert erreicht, daß die Luft dem Motor über den Kühler zugeführt werden kann und dabei eine so hohe Temperatur beibehält, daß die Selbstzündung am Ende des Verdichtungshubes erfolgt.The charging unit is started and made to work independently; the engine will started, whereby a distribution organ is operated. which the engine at least part of the of the Charger supplied air via the branch line connected in parallel to the cooler. This operation the distribution organ is maintained until the temperature of the liquid in the cooling circuit a reaches such a value that the air can be fed to the engine via the radiator and at such a high level Maintains temperature so that auto-ignition takes place at the end of the compression stroke.
Die Erfindung ist nachstehend unter Bezugnahme auf die Zeichnung beispielshalber erläutert, die ein Schema eines erfindungsgemäßen Motors darstellt.The invention is explained below by way of example with reference to the drawing, which shows a scheme represents a motor according to the invention.
Der dargestellte Dieselmotor besitzt einen geschlossenen Kühlkreis 1 für eine Flüssigkeit (z. B. Wasser oder ein Gemisch aus Wasser und einem Frostschutzmittel), welche zwischen dem Motorblock 2 und einem Kühler 3 durch eine Umlaufpumpe 4 in Umlauf gesetzt wird.The diesel engine shown has a closed cooling circuit 1 for a liquid (z. B. water or a mixture of water and an antifreeze), which is between the engine block 2 and a radiator 3 is set in circulation by a circulation pump 4.
Dieser Motor wird mit vorverdichteter Luft durch ein Aufladeaggregat mit einer Abgasturbine 5 und einem Lader 6, welche beide auf der gleichen Welle 7 sitzen, gespeist.This engine is with pre-compressed air by a charging unit with an exhaust gas turbine 5 and a Loader 6, which both sit on the same shaft 7, fed.
Die Turbine 5 wiH nvt den Auspuffgasen über eineThe turbine 5 wiH nvt the exhaust gases via a
Brennkammer 8 gespeist, wozu diese dyrch eine Leitung 9 mit der Atispuffsammelleiti'ng IO des Motors verbunden ist.Combustion chamber 8 fed, including this dyrch a line 9 with the atispuff collection line IO of the engine connected is.
Der Lader 6 speist einerseits den Motor über einen z. B. von dem Kühlkreis 1 abgezweigten Kühler 111 und andererseits die Brennkammer 8. Hierfür verbindet eint sich in 7wei Leitungen 12a und 12i> verzweigende Leitung 12 den Lader 6 einerseits mit der Einlaßsammelleitung 13 des Motors (Zweig 12a) und andererseits mit der Brennkammer 8(Umblaseleitung 126).The charger 6 on the one hand feeds the engine via a z. B. branched off from the cooling circuit 1 cooler 111 and on the other hand, the combustion chamber 8. For this purpose, two lines 12a and 12i are connected in 7 branching line 12 the charger 6 on the one hand with the intake manifold 13 of the engine (branch 12a) and on the other hand with the combustion chamber 8 (blow-by line 126).
Außerdem ist eine Abzweigleitung 14 parallel zu dem Kühler 11 angeordnet und ist ein Verteilungsorgan 15 an der Abzweigstelle der Abzweigleitung 14 vorgesehen. Die Abzweigleitung ist bei Normalbetrieb des Motors eine Kühlerumgehungsleitung. Das Verteilungsorgan 15 kann so gesteuert werden, daß die Gesamtheit der von dem Lader 6 gelieferten Luft durch die Abzweigleitung 14 ströi.it, wobei dann der nicht dem Motor zugeführte Teil dieser Luft die Brennkammer 8 speist, indem er in gegenüber dem Normalbetrieb entgegengesetztem Sinn den Kühler 1 durchströmt, was eine schnellere Erwärmung der Flüssigkeit des Kühlkreises I bewirkt. Das Verteilungsorgan 15 kann auch so gesteuert werden, daß nur ein Teil der von dem Lader 6 gelieferten Luft durch die Abzweigleitung 14 strömt, wobei dann der übrige Teil der Luft unmittelbar über die Umblaseleiuing 12;»die Brennkammer 8 speist.In addition, a branch line 14 is arranged parallel to the cooler 11 and is a distribution member 15 provided at the junction of the branch line 14. The branch line is during normal operation of the Engine a radiator bypass line. The distribution member 15 can be controlled so that the whole of the air supplied by the charger 6 ströi.it through the branch line 14, in which case the not the Part of this air supplied to the engine feeds the combustion chamber 8 by being in opposite to normal operation the opposite sense flows through the cooler 1, resulting in faster heating of the liquid in the cooling circuit I causes. The distribution member 15 can also be controlled so that only a part of the loader 6 Delivered air flows through the branch line 14, then the remaining part of the air directly over the Umblaseleiuing 12; »the combustion chamber 8 feeds.
Um das Arbeiten des Verteilungsorgans 15 automatisch zu machen, kann seine Steuerung zweckmäßig durch die Temperatur der Flüssigkeit des Kühlkreises 1 erfolgen, und zwar derart, daß, solange diese Temperatur kleiner als ihr normaler Wert bleibt, das Verteilungsorgan eine solche Stellung einnimmt, daß wenigstens ein Teil der von dem Lader 6 gelieferten Luft durch die Abzweigleitung 14 strömt, während, wenn die Temperatur größer als dieser normale Wert wird, das Verteilungsorgan 15 eine solche Stellung einnimmt, daß der Eingang der Abzweigleitung 14 geschlossen wird.In order to make the work of the distribution organ 15 automatically, its control can be expedient take place by the temperature of the liquid of the cooling circuit 1, in such a way that as long as this temperature remains smaller than its normal value, the organ of distribution occupies such a position that at least one Part of the air supplied by the supercharger 6 flows through the branch line 14 while when the temperature becomes greater than this normal value, the distribution member 15 occupies such a position that the input of the branch line 14 is closed.
Das Anlassen eines auf die obige Weise ausgebildeten Motors erfoigt dann folgendermaßen:A motor designed in the above way is then started as follows:
Das Laderaggregat 5,6,7 wird mittels eines Anlassers 16 angelassen und in den Zustand des selbstständigen Betriebs gebracht, indem die Brennstoffmenge entsprechend eingestellt wird, welche von einem die Brennkammer 8 mit Brennstoff beliefernden Einspritzer 47 geliefert wird;The charger unit 5,6,7 is activated by means of a starter 16 started and brought into the state of the independent operation by the amount of fuel accordingly is set, which is supplied by an injector 47 that supplies the combustion chamber 8 with fuel is delivered;
der Motor wird mittels eines Anlassers 18 angeworfen, wobei gleichzeitig das Verteilungsorgan 15 betätigt wird (von Hand, oder automatisch, wenn seine Steuerung durch die Temperatur der Flüssigkeit des Kühlkreises 1 erfolgt);the engine is started by means of a starter 18, the distribution member 15 being actuated at the same time is (manually, or automatically, if its control by the temperature of the liquid of the Cooling circuit 1 takes place);
diese Betätigung des Verteilungsorgans 15 wird aufrechterhalten, bis die Temperatur der Flüssigkeit des Kühlkreises 1 ihren normalen Wert erreicht.this actuation of the distribution member 15 is maintained until the temperature of the liquid des Cooling circuit 1 has reached its normal value.
Die beschriebene Dieselbrennkraftmaschine kann also leicht in Betrieb gesetzt und schnell auf ihre Betriebstemperatur gebracht werden.The diesel internal combustion engine described can therefore be put into operation easily and quickly on its own Operating temperature are brought.
Ein derartiger Motor ermöglicht offenbar bei seinem Einbau in ein Fahrzeug eine äußerst schnelle Inbetriebsetzung desselben. Ferner sind die crfindungsgemaßcn Verbesserungen einfach, billig herzustellen und arbeiten sehr zuverlässig automatisch.Such a motor evidently enables extremely quick start-up when installed in a vehicle same.
