- thermal resistance of these compositions was also measured using the continuous ECBT test, where the mass of deposits (in mg) generated under determined conditions is measured. The lower this mass, the better the thermal resistance.
- the test uses aluminum beakers that simulate the shape of pistons. These beakers are placed in a glass container, maintained at a controlled temperature of around 60 ° C.
- the lubricant is placed in these containers, themselves equipped with a wire brush, partially immersed in the lubricant. This brush is driven in a rotary motion at a speed of 1000 revolutions per minute, which creates a projection of lubricant on the lower surface of the beaker.
- the beaker is maintained at a temperature of 310 ° C by an electric heating resistance, regulated by a thermocouple.
- Table III Compositions L 1 L 2 L 3 L4 L 5 L 6 Fuel reduction (%) 0.5 0.2 0.5 0.2 0.7 0.7 ECBT (mg) 365 335 355 330 600 430

- the addition of the glycerol ester ensures satisfactory crankcase cleanliness.
- Additivation by a combination of a hydrogenated styrene / isoprene copolymer, an olefin copolymer and a glycerol ester therefore makes it possible to formulate a “fuel eco” marine lubricant while maintaining good crankcase cleanliness.
