Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 sowie ein Steuergerät nach dem Oberbegriff des Anspruchs 7.The The present invention relates to a method according to the preamble of claim 1 and a control device according to the preamble of claim 7.
Ein
solches Verfahren und ein solches Steuergerät ist jeweils

Die Viskosität des Motoröls sinkt mit zunehmender Motoröltemperatur. Bei hohen Motoröltemperaturen fließt daher vergleichsweise viel Motoröl durch Lecks wie Lagerspalte im Schmierölkreisablauf ab, was den Öldruck absinken lässt. Bei niedrigen Motordrehzahlen ist auch die Drehzahl der Ölpumpe niedrig. Sie liefert daher nur kleine Volumenströme. Daher kann der Öldruck in Betriebspunkten mit hohen Öltemperaturen und niedrigen Drehzahlen unter Mindestwerte sinken, die zum Beispiel für Öldruckbetätigte Nockenwellenwinkel-Verstellungen und/oder Ventilhub-Umschaltungen erforderlich sind.The Viscosity of engine oil decreases with increasing Engine oil temperature. At high engine oil temperatures Therefore, comparatively much engine oil flows through Leaks such as bearing gaps in the lubricating oil circuit drain off what the oil pressure drops. At low engine speeds is too the speed of the oil pump low. It therefore only supplies small volume flows. Therefore, the oil pressure in Operating points with high oil temperatures and low Speeds fall below minimum values, which for example for oil pressure actuated Camshaft angle adjustments and / or valve lift switching required are.

Die Aufgabe der Erfindung besteht dagegen in der Angabe eines Verfahrens und einer Vorrichtung, die jeweils eine Verwendung einer vergleichsweise kleinen und leichten, mechanisch angetriebenen Ölpumpe erlauben, ohne auf eine elektrisch angetriebene und bedarfsweise zuschaltbare Zusatzölpumpe zur Aufrechterhaltung eines Mindestwertes für den Öldruck im Heißleerlauf-Betriebspunkt angewiesen zu sein.The The object of the invention, however, is to specify a method and a device each having a use of a comparative small and light, mechanically driven oil pump allow, without being on an electrically driven and if necessary switchable additional oil pump to maintain a Minimum value for the oil pressure at the hot idle operating point to be instructed.
Diese Aufgabe wird jeweils mit den Merkmalen der unabhängigen Ansprüche gelöst.These Task is in each case with the characteristics of the independent Claims solved.
Bei der Erfindung wird der Gefahr eines zu geringen Öldrucks im Heißleerlauf-Betriebspunkt durch Ergreifen einer Maßnahme zur Senkung der Öltemperatur begegnet. Je niedriger die Öltemperatur bei ansonsten gleichen Bedingungen ist, desto höher ist der Öldruck. Die erfindungsgemäß erreichte Absenkung der Motoröltemperatur im Heißleerlauf-Betriebspunkt bewirkt damit eine erwünschte Erhöhung des Öldrucks in diesem Betriebspunkt, so dass auch eine vergleichsweise kleine, mechanisch angetriebene Ölpumpe ohne Zuschalten einer elektrisch angetriebenen Zusatzölpumpe verwendet werden kann. Es hat sich gezeigt, dass die mögliche Verkleinerung der mechanisch angetriebenen Ölpumpe die Größenordnung einer Halbierung des Bauraums und der Masse der Ölpumpe erreichen kann. Damit wird neben einer Verringerung der Kosten auch eine Verbesserung des Wirkungsgrades der Ölpumpe und eine Reduzierung des Antriebsleistungsbedarf der Ölpumpe erreicht, wobei eine Reduzierung um bis zu 40% erwartet werden kann. Eine kleinere Ölpumpe zeichnet sich darüber hinaus durch geringere Füllungsverluste und eine geringere Kavitationsneigung aus. Die Gewichts- und Wirkungsgrad-Vorteile verringern den Kraftstoffverbrauch und damit auch die CO2-Emission.In the invention, the risk of too low oil pressure in the hot idle operating point is countered by taking a measure to reduce the oil temperature. The lower the oil temperature under otherwise identical conditions, the higher the oil pressure. The inventively achieved lowering the engine oil temperature in the hot idle operating point thus causes a desired increase in the oil pressure at this operating point, so that even a comparatively small, mechanically driven oil pump can be used without connecting an electrically driven auxiliary oil pump. It has been shown that the possible reduction of the mechanically driven oil pump can reach the order of magnitude of a halving of the construction space and the mass of the oil pump. Thus, in addition to a reduction in costs, an improvement in the efficiency of the oil pump and a reduction in the power requirement of the oil pump is achieved, with a reduction of up to 40% can be expected. A smaller oil pump is also characterized by lower filling losses and a lower cavitation tendency. The weight and efficiency benefits reduce fuel consumption and thus CO 2 emissions.
Weitere Vorteile ergeben sich aus den abhängigen Ansprüchen, der Beschreibung und den beigefügten Figuren.Further Advantages result from the dependent claims, the description and the attached figures.
