Abstract
Description
Die Erfindung betrifft eine Schmierölversorgungseinrichtung für eine Brennkraftmaschine gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The The invention relates to a lubricating oil supply device for one Internal combustion engine according to the features of the preamble of claim 1.
Es
ist allgemein bekannt, dass bei einer Brennkraftmaschine zur Kühlung des
Schmieröls
ein entsprechender Wärmetauscher
bzw. Ölkühler vorgesehen
ist (siehe z.B.
Aus
dem Stand der Technik sind weiterhin variable Ventiltriebe bekannt
(siehe z.B.
Insbesondere der Ölkühler der Brennkraftmaschine stellt einen hydraulischen Widerstand dar, der vor allem bei niedrigen Öltemperaturen einen entsprechenden Druckabfall erzeugt. Nachgeschaltete Verbraucher, wie das hydraulisch betätigbare variable Ventilsteuersystem können aufgrund nicht ausreichenden Öldrucks bzw. Ölmenge nachteilig beeinflusst werden.Especially the oil cooler the Internal combustion engine represents a hydraulic resistance that especially at low oil temperatures generates a corresponding pressure drop. Downstream consumers, like the hydraulically actuated variable valve control system can due to insufficient oil pressure or oil quantity be adversely affected.
Aufgabe der Erfindung ist es, derartige Nachteile zu vermeiden.task The invention is to avoid such disadvantages.
Die Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst.The The object is achieved by the features specified in claim 1 solved.
Dadurch, dass die Schmierölversorgung für die variable Ventilsteuerung unter Umgehung des Ölkühlers erfolgt, wird in allen Betriebszuständen des Motors, insbesondere beim Kaltstart, eine sicherer und schneller Druckaufbau für die Ansteuerung der variablen Ventilsteuerung erreicht. Über die Veränderung der Ventilsteuerzeiten lassen sich insbesondere beim kalten Motor wirkungsvoll die Abgasemissionen reduzieren.Thereby, that the lubricating oil supply for the Variable valve control, bypassing the oil cooler, is used in all operating conditions the engine, especially when cold starting, a safer and faster Pressure build-up for achieved the control of the variable valve timing. About the change the valve timing can be particularly in the cold engine Effectively reduce exhaust emissions.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Schmierölsystems sind den Unteransprüchen zu entnehmen.Further advantageous embodiments and further developments of the lubricating oil system according to the invention are the dependent claims refer to.
Die variable Ventilsteuerung besteht aus einer Nockenwellenverstellung sowie einer Ventilhubumschaltung, die im vorliegenden Ausführungsbeispiel durch schaltbare Tassenstössel umgesetzt ist.The variable valve timing consists of a camshaft adjustment and a valve lift, in the present embodiment by switchable bucket tappets implemented.
Eine effektive und wirkungsvolle Kühlung ergibt sich, wenn der Ölkühler als Öl/Wasser-Plattenwärmetauscher ausgebildet ist.A effective and effective cooling arises when the oil cooler as an oil / water plate heat exchanger is trained.
Stromab des in der Hauptöldruckleitung angeordneten Ölkühlers ist ein Ölfilter vorgesehen, wobei zwischen Ölfilter und Ölkühler die Ölversorgungsleitung für die hydraulische Ansteuerung der variablen Ventilsteuerung abzweigt.Downstream in the main oil pressure line arranged oil cooler is an oil filter provided, being between oil filters and oil cooler the oil supply pipe for the hydraulic control of the variable valve control branches off.
Ein Ausführungsbeispiel der Erfindung ist in der nachfolgenden Beschreibung und Zeichnung näher erläutert.One embodiment The invention is described in the following description and drawings explained in more detail.
Die einzige Figur zeigt einen Hydraulikschaltplan einer aufgeladenen zweireihigen Brennkraftmaschine mit acht Zylindern.The single figure shows a hydraulic circuit diagram of a charged Double-row internal combustion engine with eight cylinders.
