Abstract

Partly-synthetic engine oils contg. >10 wt.% aliphatic diesters of viscosity 3-5 cS at 100 degrees C, and polymers to improve the viscosity index, in which the polymer is added as a soln. of aliphatic diesters of above viscosity. Internal cleanliness of engines, esp. diesel engines is improved by use of diesters instead of mineral-based spindle oil as solvent.

Description

Verbesserungsmittel für Schmieröle Zur Herstellung sogenannter Mehrbereichsöle, wie sie insbesondere für Motore für Kraftfahrzeuge benötigt werden, verwendet man Mineralölraffinate geeigneter Viskosititslasen, die ausser den üblichen Additiven noch Lösungen von Polvmeren in Verdünnungsölen enthalten. Diese dienen zur Verbesserung des Viskositätsindex und werden als Viskositätsindexverbesserer (" V.I.-Improver ") bezeichnet. Die Polvmeren sollen die Viskosität des Öles in der Kälte kaum, in der Hitze jedoch stark erhöhen. Das Schmieröl gewinnt dadurch die wertvolle Eigenschaft des Mehrbereichsöles. 3eim Schmieren von Motoren oder Getrieben vereinigen sie gutes Kälte- mit gutem Hitzeverhalten. Improver for lubricating oils For the production of so-called multigrade oils, as they are needed in particular for engines for motor vehicles, one uses Mineral oil refinates of suitable viscosity glasses, which, in addition to the usual additives still contain solutions of polymers in thinner oils. These are used for improvement the viscosity index and are used as viscosity index improvers ("V.I.-Improver "). The polymer should hardly increase the viscosity of the oil in the cold, in however, increase the heat greatly. This gives the lubricating oil its valuable property of the multigrade oil. They combine good things when lubricating engines or gears Cold with good heat behavior.

Allerdings pflegen alle Polymeren mehr oder weniger die innere Sauberkeit heisslaufender Motoren zu beeinträchtigen. Dies gilt vor allem für Dieselmotoren unc ilier wieder besonders für aufgeladene T)ieselmotoren.However, all polymers maintain more or less internal cleanliness overheating engines. This is especially true for diesel engines unc ilier again especially for turbocharged diesel engines.

Es wurde nun gefunden, dass dieser nachteilige Einfluss auf die motorische Sauberkeit weitgehend vermieden werõen kann, wenn die Dolvmere nicht wie üblich in minerlaischen Stellölen (Solventraffinate in Spindelöl-Viskositätslage) gelöst werden, sondern in Triestern, wie sie zur Herstellung von teilsynthetischen Motorenölen Verwendung finden.
