Gebiet der ErfindungField of the invention
Hubkolbenbrennkraftmaschine nach dem 4-Takt-Verfahren mit einem Kurbelgehäuse, in dem zumindest eine Zylinder/Kolbeneinheit angeordnet ist, wobei der Kolben mittels eines mit einer Kurbelwelle verbundenen Pleuels geführt ist, mit zumindest einem den Zylinder verschließenden Zylinderkopf, dessen Ein- und Auslasskanäle von zumindest je einem Ein- und Auslassventil beherrscht sind, die durch von einer Nockenwelle mittels Ein- und Auslassnocken angetriebene Schlepp- oder Kipphebel betätigbar sind, wobei die Hebel auf zumindest einer Achse geführt sind, mit zumindest einem Zusatznocken im Bereich des Grundkreises des Auslassnockens zum zusätzlichen Öffnen zumindest eines Auslassventils und mit einem Steuerelement, das zwischen dem Schlepp- oder Kipphebel und dem oder den Auslassventilen eingebaut ist, mit einer Druckölquelle verbindbar und in seiner Länge so steuerbar ist, dass beim Dekompressionsbetrieb der Zusatznocken wirksam und beim reinen Motorbetrieb unwirksam ist.Reciprocating internal combustion engine according to the 4-stroke method with a crankcase, in which at least one cylinder / piston unit is arranged, wherein the piston is guided by means of a connecting rod connected to a crankshaft, with at least one cylinder head closing the cylinder, the inlet and outlet of at least each one inlet and outlet valves are controlled, which are actuated by driven by a camshaft by means of inlet and exhaust cam drag or rocker arm, wherein the levers are guided on at least one axis, with at least one additional cam in the region of the base circle of the exhaust cam for additional opening at least one exhaust valve and with a control element which is installed between the towing or rocker arm and the exhaust valves or connected to a pressure oil source and its length is controllable so that the decompression operation of the additional cam is effective and in pure engine operation ineffective.
Hintergrund der ErfindungBackground of the invention
Eine derartige gattungsbildende Hubkolbenbrennkraftmaschine ist aus der
Nachteilig bei dieser Ausgestaltung ist, dass der Öldruck direkt zur Betätigung des Kolbens benutzt wird und daher hoher Druck oder ein großer Kolbenquerschnitt erforderlich ist und sich starke Druckschwankungen einstellen können. Weiterhin sind im Motorbetrieb zusätzliche Maßnahmen erforderlich, um wegen erhöhten Spiels im Grundkreisbereich des Auslassnockens Schwingungen der Übertragungselemente zu vermeiden. Auch wird die zusätzliche Ventilspieleinstellschraube als nachteilig empfunden, weil sie unabhängig von dem Mehraufwand mit Gewinde und dergleichen auch eine zusätzliche unerwünschte Masse darstellt.A disadvantage of this embodiment is that the oil pressure is used directly for actuating the piston and therefore high pressure or a large piston cross section is required and can set strong pressure fluctuations. Furthermore, additional measures are required in engine operation to avoid vibrations of the transmission elements due to increased clearance in the base circle region of the exhaust cam. Also, the additional valve lash adjuster is considered disadvantageous because it also represents an additional undesirable mass, regardless of the extra effort with thread and the like.
Es ist weiterhin eine Hubkolbenbrennkraftmaschine mit Dekompressionseinrichtung bekannt (
Der erforderliche Bauaufwand, die Zusatznocken ein- und auszufahren, ist erheblich und kostenaufwendig und wird daher als nachteilig empfunden.The required construction cost, the additional cams and extend, is considerable and expensive and is therefore perceived as disadvantageous.
Aufgabe der ErfindungObject of the invention
Aufgabe der Erfindung ist es daher, eine Hubkolbenbrennkraftmaschine mit eingangs beschriebenen Merkmalen so zu verbessern, dass eine wirksame Motorbremse durch intermittierendes Öffnen eines oder mehrerer Auslassventile im Bereich des oberen Todpunktes der Hubkolbenbrennkraftmaschine zur Verfügung gestellt wird, die mit einfachen Mitteln und kostengünstig zu realisieren ist. Dies soll darüber hinaus in Verbindung mit Bauteilen eines hydraulischen Ventilspielausgleichselements erfolgen. Zusätzlich soll das Ventilspiel einfach eingestellt werden können.The object of the invention is therefore to improve a reciprocating internal combustion engine having the characteristics described above so that an effective engine brake is provided by intermittently opening one or more exhaust valves in the region of the upper dead center of the reciprocating internal combustion engine, which can be realized with simple means and cost. This should also be done in conjunction with components of a hydraulic valve clearance compensation element. In addition, the valve clearance should be easy to adjust.
Zusammenfassung der ErfindungSummary of the invention
Die Aufgabe der Erfindung wird dadurch gelöst, dass das Steuerelement als Aufpumpelement ausgebildet ist und mit einem Arbeitskolben unter Zwischenschaltung eines Distanzstückes mit einer mehreren Auslassventilen zugeordneten Brücke oder einem Ventilschaft eines Auslassventils in Wirkverbindung steht.The object of the invention is achieved in that the control element is designed as an inflation element and is in operative connection with a working piston with the interposition of a spacer with a plurality of exhaust valves associated bridge or a valve stem of an exhaust valve.
Durch diese Ausgestaltung ist nur ein Steueröldruck von geringer Druckhöhe erforderlich, da das Aufpumpelement selbsttätig Druck aufbaut.By this configuration, only a control oil pressure of low pressure level is required because the inflating automatically builds pressure.
Weiterhin kann durch Verwendung von Distanzstücken, die in ihrer Höhe gestuft ausgebildet sind, durch entsprechendes Wechseln und Einbau des passenden Distanzstückes das Ventilspiel ausgeglichen werden.Furthermore, by using spacers that are stepped in their height, the valve clearance can be compensated by appropriate replacement and installation of the appropriate spacer.
Es sei darauf hingewiesen, dass die erfindungsgemäße Ausbildung zusätzlich zur Dekompressionseinrichtung als Motorbremse auch zur inneren Abgasrückführung oder Hybridisierung zur Anwendung kommen kann.It should be noted that the inventive design can be used in addition to the decompression device as an engine brake for internal exhaust gas recirculation or hybridization.
In vorteilhafter Weiterbildung der Erfindung wird vorgeschlagen, dass die Distanzstücke als Kugelpfannen ausgebildet sind, die mit einem Kugelkopf des Arbeitskolbens in Wirkverbindung stehen. Durch die Verwendung einer Kugelpfanne und eines Kugelkopfes werden ungewollte Flächenpressungen vermieden. Weiterhin haben Kugelpfannen den Vorteil, dass sie verliersicher am Kugelkopf des Arbeitskolbens des Aufpumpelements festgelegt werden können und die Brücke oder der Ventilschaft keine zusätzlichen Aufnahmen benötigen.In an advantageous embodiment of the invention, it is proposed that the spacers are designed as ball sockets, with a ball head the working piston are in operative connection. By using a ball socket and a ball head unwanted surface pressures are avoided. Furthermore, ball pans have the advantage that they can be set captive on the ball head of the working piston of the inflating and the bridge or valve stem need no additional recordings.
Weiterhin wird vorgeschlagen, dass das Aufpumpelement die Bauteile eines hydraulischen Ventilspielausgleichselements (HVA), wie Arbeitskolben, Gehäuse, Rückstellfeder, Kolben und Rückschlagventil am Kolben, aufweist, dass weiterhin ein Steuerkolben vorgesehen ist, der einerseits durch eine Feder belastet und andererseits durch Drucköl beaufschlagbar ist, und dass der Steuerkolben mit dem Ventilkörper des Rückschlagventils im Öffnungssinne in Wirkverbindung steht.Furthermore, it is proposed that the inflating the components of a hydraulic valve clearance compensation element (HVA), such as working piston, housing, return spring, piston and check valve on the piston, further comprising a control piston is provided which is loaded on the one hand by a spring and on the other hand acted upon by pressurized oil , And that the control piston is in operative connection with the valve body of the check valve in the opening direction.
Wird der Steuerkolben mit reduziertem Öldruck beaufschlagt, dann drückt die Feder den Steuerkolben gegen den Ventilkörper des Rückschlagventils, der vorzugsweise als Kugel ausgebildet ist, und öffnet diesen. Dadurch kann sich das Steuerelement verkürzen, so dass der Zusatznocken unwirksam ist und kein Dekompressionsöffnen des oder der Auslassventile erfolgt. Die Rückstellfeder bleibt aber weiterhin wirksam, so dass kein unkontrolliertes Spiel im Bereich des Grundkreises des Auslassventils entsteht und keine unkontrollierten Schwingungen der Übertragungselemente entstehen. Der Schlepp- oder Kipphebel, ggf. auch ein eingebauter Stößel, kontaktiert den Zusatznocken daher immer. Der Zusatzhub wird durch das Aufpumpelement in diesem Fall aber ausgeblendet.If the control piston is acted upon by reduced oil pressure, the spring presses the control piston against the valve body of the check valve, which is preferably designed as a ball, and opens it. As a result, the control can shorten, so that the additional cam is ineffective and no decompression opening of the outlet valve or valves takes place. However, the return spring remains effective, so that no uncontrolled play in the region of the base circle of the exhaust valve is formed and no uncontrolled vibrations of the transmission elements arise. The towing or rocker arm, possibly also a built-in plunger, therefore always contacts the additional cam. The additional stroke is hidden by the inflatable element in this case, however.
Wird der Steuerkolben mit Öldruck beaufschlagt, dann kann das Rückschlagventil schließen und es baut sich ein Druck im Hochdruckraum zwischen Gehäuse, Arbeitskolben und Kolben auf. Der ausgebildete Hochdruckraum sorgt für das Wirksamwerden des Zusatznockens, wodurch die Dekompressionseinrichtung, die Abgasrückführeinrichtung oder eine Hybridisiervorrichtung eingeschaltet wird.If the control piston is acted upon by oil pressure, then the check valve can close and it builds up a pressure in the high-pressure chamber between the housing, working piston and piston. The formed high pressure chamber provides for the effectiveness of the additional cam, whereby the decompression device, the exhaust gas recirculation device or a hybridization device is turned on.
