Abstract:
An additive composition for a fuel comprises: (i) a metal compound selected from an iron compound, a manganese compound, a calcium compound, a cerium compound and mixtures thereof; (ii) an organic compound selected from a bicyclic monoterpene, substituted bicyclic monoterpene, adamantane, propylene carbonate and mixtures thereof; and (iii) a stabiliser. The additive composition allows fuels which are prone to separation, for example blended fuels or fuels having a high content of asphaltenes, to be used successfully.
Abstract:
The present invention relates to novel uses of copolymers for removing and/or reducing deposits in the fuel system and/or injection system of direct-injection diesel and/or gasoline engines.
Abstract:
A diesel fuel composition containing metallic additives that are stabilised against phase separation. The diesel fuel contains a colloidally dispersed or solubilised metal catalyst compound, which can be used for diesel particulate trap regeneration and, as a stabiliser, 5-1,000 ppm (weight) of an oil-soluble or oil-dispersible organic compound having a lipophilic hydrocarbyl chain having attached directly thereto at least two contiguous polar head functional groups, i.e., the functional groups are separated by no more than three carbon atoms. The diesel fuel composition is particularly suitable for use with diesel engines fitted with a particulate trap for emissions control.
Abstract:
The present invention provides a lubricating oil composition including a viscosity index improver (A) containing a comb-shaped polymer and having an SSI (shear stability index) of 30 or less together with a base oil, wherein an HTHS viscosity (high temperature high shear viscosity) at 150°C (T 150 ) is 1.6 to 2.9 mPa·s, and a ratio of a kinematic viscosity at 40°C (V 40 ) [mm 2 /s] to the HTHS viscosity at 150°C (T 150 ) [mPa·s] (V 40 /T 150 ) is 12.4 or less. The lubricating oil composition of the present invention is excellent in fuel consumption reducing properties in a low-temperature region assuming the time of starting an engine while making various properties, such as a viscosity, etc., in a high-temperature region assuming the time of high-speed operation of an engine favorable.
