A lubricant suitable for lubricating a two-stroke cycle engine which is fueled with a liquid fuel having a volatility less than that of gasoline comprises an oleaginous synthetic ester, a normally liquid solvent having a kinematic viscosity of less than about 5 or 2 mm2/s at 100°C and a nitrogen-containing dispersant bearing a hydrocarbyl group of at least 26 carbon atoms and having a nitrogen content of at least 4 percent by weight. The nitrogen content of the lubricant is at least about 0.3 percent by weight.
La présente invention concerne un lubrifiant approprié pour lubrifier un moteur à deux temps qui est alimenté avec un carburant liquide ayant une volatilité inférieure à celle de l'essence comprenant un ester synthétique oléagineux, un solvant normalement liquide ayant une viscosité cinématique inférieure à environ 5 ou 2 mm2/s à 100°C et un dispersant contenant de l'azote portant un groupe hydrocarbyle d'au moins 26 atomes de carbone et ayant une teneur en azote d'au moins 4 pourcent en poids. La teneur en azote du lubrifiant est d'au moins environ 0,3 pourcent en poids.
