Problems solved by technology

In particular, it has been found that dilution of lubricating compositions with FAAEs such as FAME may result in an undesired loss of viscosity of the lubricating composition such that the lubricating composition no longer meets the specified viscosity grade and / or no longer provides lubricating protection to the engine

[0052] Further details of the preparation methods of the comb polymers used herein can be found in US2010 / 0190671 and US2008 / 0194443, which are incorporated herein by reference.

[0053] The comb polymer used in the present invention comprises repeating units derived from polyolefin-based macromonomers. These repeat units contain at least one group derived from polyolefins. Examples of suitable polyolefins include C2-C10 alkenes such as ethylene, propylene, n-butene, isobutene, norbornene and / or C4-C10 alkadienes such as butadiene, isoprene, norbornadiene, etc. .

[0054] The repeat units derived from polyolefin-based macromers preferably comprise at least 70 wt%, more preferably at least 80 wt%, most preferably at least 90 wt%, based on the weight of repeat units derived from polyolefin-based macromers % of groups derived from alkenes and / or alkadienes.

[0055] The polymer groups may also be present in hydrogenated form. The repeat units derived from polyolefin-based macro...

Abstract

Use of a comb polymer for reducing the loss in viscosity of a lubricating composition for the crankcase of an internal combustion engine, wherein the internal combustion engine is fuelled by a fuel composition comprising a fatty acid alkyl ester.

Description

technical field [0001] The present invention relates to a lubricating composition especially for use in the crankcase of an internal combustion engine fueled with biodiesel. Background technique [0002] Government regulations and market demands continue to emphasize fossil fuel conservation in the transportation industry. There is thus an increasing demand for vehicles fueled with fuels from renewable or bio-derived sources. [0003] It is known to incorporate fatty acid alkyl esters (FAAE), especially fatty acid methyl esters (FAME) in diesel fuel compositions. FAMEs are produced with methanol in the presence of a catalyst through a chemical process called transesterification to produce methyl esters. FAMEs can be produced from various oil-derived feedstocks such as soybean, rapeseed, sunflower seed, coconut and used vegetable oils. FAAE can be added for a variety of reasons, including to reduce the environmental impact of fuel production and consumption or to improve l...
