An oil blending system for a marine diesel two-stroke engine and/or generator comprises a blender having at least one inlet for receiving a lubrication oil and at least one other component and at least one outlet for outputting a mixed lubrication oil composition to the engine or generator. A blender controller is configured to receive parameter data on the current lubrication oil status used in the engine or generator and receive parameter data on the current engine and/or generator status. The blender controller is also configured to automatically determine whether the currently used lubrication oil is within a predetermined parameter range based on the current engine and/or generator status. If the current lubrication oil is outside a predetermined parameter threshold, the blender controller is configured to determine a new lubrication oil composition for the engine or generator.

A lubricant additive dispensing system includes a cartridge defining an inner cavity to house at least one additive material section and a release opening in communication with a lubrication circulation system of a machine. The lubricant additive dispensing system also includes a spring element arranged to bias the at least one additive material section towards the release opening and a release lever arranged to selectively retain the at least one additive material sections within the cartridge. The lubricant additive dispensing system further includes an actuator coupled to the release lever wherein actuation of the release lever ejects a next one of the at least one additive material sections into the lubrication circulation system.

A method for preventing or reducing low speed pre-ignition in an engine lubricated with a lubricating oil while maintaining or improving cleanliness by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and at least one boron-containing compound and at least one overbased calcium detergent as minor components. The at least one boron-containing compound includes at least one borated dispersant, or a mixture of a boron-containing compound and a non-borated dispersant. The boron to nitrogen ratio for the at least one boron-containing compound is less than or equal to about 0.3 and the lubricating oil is essentially free of elemental magnesium. The lubricating oils of this disclosure are particularly advantageous as passenger vehicle engine oil (PVEO) products.

This drive system for a motor vehicle includes a top end and a bottom end that are coupled together, a kinematic drive chain, a compressor, a main lubrication system, that includes a main circuit and a main pump, which supplies at least the bottom end with a main lubricant via the main circuit, and a secondary lubrication system, that includes at least one secondary circuit separated from the main circuit and at least one secondary pump separate from the main pump, the secondary pump supplying the top end and/or the compressor with a secondary lubricant via the secondary circuit. The secondary lubrication system includes at least one secondary actuator mechanically separate from the kinematic drive chain and that drives the secondary pump to supply the top end and/or the compressor with the secondary lubricant.

The present invention relates to methods of forming a film between two surfaces, in which the film includes diamond-like carbon. Also provided herein are uses of such films, such in sliding contacts and in metal coatings.

A lubrication system in a machine includes a sump to collect a bulk portion of lubricant and a pump adapted to circulate the lubricant from the sump through a lubricant line to an area of the machine for lubrication. The lubrication system also includes an oil filter disposed along the lubrication line adapted to filer the lubricant flowing through the lubricant line. The lubrication further includes an additive fixture in fluid flow communication with the oil filter adapted to house at least one additive material section and distribute the additive material in a lubrication flow circulation.
