Definitions

  • This invention relates to the use of an additive for providing a low sulphur fuel oil with improved lubricity and other benefits and to fuel oil compositions containing the additives.
  • US-A-4,409,000 describes additives for normally liquid fuels for providing carburettor and engine detergency.
  • a combination of at least one hydroxyl amine of specified formula and at least one hydrocarbon soluble carboxylic dispersant is proposed for inhibiting the formation of sludge in the carburettor and engine.
  • the sole exemplification relates to the use of such combinations of ingredient in gasoline.
  • the compositions provide carburettor and engine detergency no other information is provided as to properties provided by these compositions.
  • US-A-2,527,889 describes polyhydroxy alcohol esters as primary anti-corrosion additives in diesel engine fuel
  • GB-A-1 ,505,302 describes ester combinations including, for example, glycerol monoesters and glycerol diesters as diesel fuel additives, for combinations being described as leading to advantages- including less wear of the fuel-injection equipment, piston rings and cylinder liners.
  • GB-A-1, 505,302 is, however, concerned with overcoming the operational disadvantages of corrosion and wear by acidic combustion products, residues in the combustion chamber and in the exhaust system.
  • the document states that these disadvantages are due to incomplete combustion under certain operating conditions.
  • Typical diesel fuels available at the date of the document contained, for example, from 0.5 to 1 % by weight of sulphur, as elemental sulphur, based on the weight of the fuel.
  • the sulphur content of diesel fuels has now been or will be lowered in a number of countries for environmental reasons, i.e. to reduce sulphur dioxide emissions.
  • heating oil and diesel fuel sulphur content are being harmonised by the CEC at a maximum of 0.2% by weight, and, at a second stage, the maximum content in diesel fuel will be 0.05% by weight. Complete conversion to the 0.05% maximum may be required during 1996.
  • the process for preparing low sulphur content fuels in addition to reducing sulphur content, also reduces the content of other components of the fuel such as polyaromatic components and polar components. Reducing one or more of the sulphur, polyaromatic and polar component content of the fuel creates a new problem in use of the fuel, i.e. the ability of the fuel to lubricate the injection system of the engine is reduced such that, for example, the fuel injection pump of the engine can fail relatively early in the life of an engine, failure being, e.g. in rotary distributor pumps, in high pressure fuel injection systems such as high pressure rotary distributors, in-line pumps and unit injectors and injectors. Such severe failures are not due to corrosive wear as described in GB-A-1 ,505,302.

  • each of a, b and c may be 0, providing that at least one of a, b or c is an integer between 1 and 75.

  • a compression-ignition (diesel) engine for controlling wear rate in the injection system of the engine in operation of the engine.

  • a compression-ignition (diesel) engine comprising providing a fuel oil composition as defined in the first aspect of the invention as the fuel in the engine thereby to control wear rate in the injection system of the engine.
  • the additive in use of the composition in a compression-ignition internal combustion engine, is capable of forming over the range of operating conditions of the engine, at least partial mono- or multi-molecular layers of the additive on surfaces of the injection system, particularly the injector pump that are in moving contact with one another, the composition being such as to give rise, when compared with a composition lacking the additive, to one or more of a reduction in wear, a reduction in friction, or an increase in electrical contact resistance in any test where two or more loaded bodies are in relative motion under non-hydrodynamic lubricating conditions.
  • the inclusion of the additive in the fuel oil has been found to give rise to the further advantage that the tendency of the fuel oil to foam is markedly reduced, whereby the antifoaming agents conventionally added thereto may be reduced or even eliminated.
  • the additive which may be a single hydroxy amine compound or mixture of compounds, is capable of forming at least partial layers on certain surfaces of the engine.
  • the layer formed is not necessarily complete on the contacting surface. Thus, it may cover only part of the area of that contacting surface, for example 10% or more, or 50% or more.
  • the formation of such layers and the extent of their coverage of a contacting surface can be demonstrated by, for example, measuring electrical contact resistance or electrical capacitance.
  • An example of a test that can be used to demonstrate one or more of a reduction in wear, a reduction in friction or an increase in electrical contact resistance according to this invention is the High Frequency Reciprocating Rig test which will be referred to hereinafter.
  • the hydroxy amine compounds identified above as suitable for use in the invention must contain a group, R " 1 or R 8 , attached to a nitrogen atom which is an alkyi or alkenyl group having one or more double bonds, containing 4 to 50, preferably 8 to 30, and more preferably 12 to 25 carbon atoms.

  • Suitable ethoxyamines are commercially available from Armak Company under the trade names ⁇ thomeen' and ⁇ thanolomeen'.
  • concentration of hydroxy amine which is effective in significantly improving the lubricity of the fuel is extremely low and may readily be determined by the wear tests identified in the Examples. In general, a noticeable reduction in wear is observed using as little as 5 ppm of additive by weight of fuel. Preferred concentrations range from 10 ppm to 0.2% by weight. Although higher concentrations may be used the wear test should be used to determine the optimum concentration. For reasons of economics the minimum effective amount should be used. A concentration between 25 ppm and 1000 ppm is preferred.

Abstract

Cette composition de carburant comprend une proportion majeure d'un carburant provenant d'un distillat moyen d'hydrocarbure liquide possédant une teneur en soufre ne dépassant pas 0,2 % en poids du poids du carburant, ainsi qu'une proportion mineure d'une hydroxy amine, laquelle améliore le pouvoir lubrifiant du carburant. L'apport d'hydroxy amine dans le carburant réduit également de façon notable la tendance à mousser de celui-ci.
