Abstract:
A method of reducing piston deposits, smoke or wear in a diesel engine. The method involves the step of running the engine on fuel comprising an oil soluble iron carboxylate or iron complex that includes Fe3+.
Abstract:
A method of operating a marine or stationary diesel engine is disclosed in which the engine is lubricated with a single cylinder lubricant that is fed at a substantially constant feed rate to the engine. When the engine runs on fuel having a sulphur level that requires more base than is available from the cylinder lubricant, at least one overbased detergent having a base number of greater than 150 mgKOH/g is added to the fuel.
Abstract:
Determining a plurality of heart rate sections for an individual, and selecting a plurality of songs, wherein each of the plurality of songs has an average beats per minute approximately equal to an average beats per minute of one of the plurality of heart rate sections, and playing the plurality of songs in a sequence on a song playing device. The plurality of songs includes a middle song, which has an average beats per minute which is greater than the average beats per minute of all of the other songs of the plurality of songs. The plurality of songs includes one or more preceding songs which precede the middle song, and each of which has an average beats per minute which is less than the average beats per minute of the middle song. The plurality of songs includes one or more succeeding songs which succeed the middle song, and each of which has an average beats per minute which is less than the average beats per minute of the middle song.

Abstract:
An additive composition comprises at least one colloidal metal compound or metallic species and a stabilising component, wherein the stabilising component comprises the product obtainable by the condensation reaction between: (i) at least one aldehyde or ketone or reactive equivalent thereof, and (ii) at least one compound comprising one or more aromatic moieties bearing at least one hydroxyl group and at least one further substituent chosen from a hydrocarbyl group, —COOR1 or COR1, wherein R1 represents hydrogen or a hydrocarbyl group. The composition may further include at least one lubricity enhancer. Compositions of the invention tend to resist haziness, cloudiness and phase separation at relatively low and relatively high temperatures, and in the presence of lubricity enhancers and fatty acid methyl esters (FAME).
