Embodiment 1

[0174] Example 1: Evaluation of the temperature resistance performance of the lubricant composition of the present invention

[0175] This is an evaluation of the temperature resistance of lubricant compositions according to the invention by continuous ECBT testing, simulating the cleanliness of engines in the presence of such compositions.

[0176] The following lubricant compositions were tested; percentages are given corresponding to mass percentages.

[0177] Table Ia and Ib

[0178]

[0179] Table Ia

[0180]

[0181]

[0182] Table Ib

[0183] The physical and chemical properties of the compositions of Tables Ia and Ib are described in Table II

[0184] Table II

[0185]

[0186]

[0187] The temperature resistance of the compositions was therefore assessed using the continuous ECBT test, which measures the mass (in mg) of the deposit produced under defined conditions. The lower this mass, the lower the temperature resistance, ie the better the clea...

Embodiment 2

[0197] Example 2: Evaluation of the fuel consumption saving performance of the lubricant composition according to the invention

[0198]The problem here was to determine by simulation the fuel consumption saving performance by using the lubricant composition according to the invention by evaluating the traction coefficient on an MTM (Mini Traction Machine) machine according to the method described below. Tests were carried out on an MTM PCS machine in contact with ultra-polished 100C6 beads (standard steel AISI 52100) equal to 19.05mm in diameter against a flat disc with the same material and surface state properties as the bead Depend on.

[0199] The following conditions were determined for representative conditions of engine operation in the SPC (piston ring pack) region, the region of the engine where the greater majority of friction occurs and therefore the region where the fuel consumption gain is maximized:

[0200] -load on 25N beads,

[0201] -1m / s driving speed, ...

Embodiment 3

[0210] Example 3: Evaluation of the fuel consumption saving performance of the lubricant composition according to the invention

[0211] The fuel saving properties of the lubricant composition according to the invention were confirmed by tests carried out on a bench equipped with the engine MAN 5L16 / 24. The special features of this engine are described in D. In the publication titled "INNOVATOR-4C, The cutting-edge MAN B&W 5L16 / 24 test engine" by V. Doyen and J. Christensen, CIMAC Congress 2004, Kyoto (Paper 124).

[0212] A procedure specific to the stabilization conditions was developed by measuring the "fuel economy" performance of the lubricant composition as described below. The program relies on equipment typically found in test centers on engine stands:

[0213] Flush the engine and lubricant circuit with the candidate lubricant,

[0214] · Test run the engine with the candidate lubricant,

[0215] • Measurement of consumption of distillate type fuels (marine die...

Abstract

The present invention relates to a lubricating composition comprising: - at least one base oil; - at least one olefin copolymer; - at least one detergent; and - at least one linear hydrogenated styrene / butadiene copolymer. The invention also relates to the use of said composition for reducing fuel consumption in an engine and for enhancing the cleanliness of a 4-stroke or 2-stroke, preferably 4-stroke, marine engine or of a stationary engine.

Description

【Technical field】 [0001] The invention is applicable in the field of lubricating compositions, more particularly in the field of lubricating compositions for marine engines, especially for four-stroke or two-stroke marine engines, preferably for four-stroke marine engines, or for stationary engines. More particularly, the present invention relates to lubricating compositions whose use promotes fuel economy (fuel economy or FE or other gas economy or GE) and has good engine cleaning properties, especially tank cleanliness. The invention also relates to a method for reducing the consumption of fuel, especially fuel oil, of a vessel or central unit applying the lubricating composition. 【Background technique】 [0002] In the automotive field, reducing polluting emissions and achieving fuel savings are increasingly being sought due to environmental concerns. The properties of automotive engine lubricants contribute to both of these phenomena, and so-called "fuel economy" engine ...
