    摘要: Trunk piston marine engine lubrication, when the engine is fueled by heavy fuel oil, is effected by a composition of TBN in the range of 20 to 60 comprising a major amount of an oil of lubricating viscosity containing 50 mass % or more of a Group 1 basestock, and respective minor amounts of a calcium alkyl salicylate detergent system providing 40 to 90 mmol of calcium alkyl salicylate per kg of the composition, and 1 to 7 mass %, based on the mass of the composition, of an oil-soluble polyalkenyl-substituted carboxylic acid anhydride, wherein the or at least one polyalkenyl group is derived from a polyalkene having a number average molecular weight of from 200 to 3,000. Asphaltene precipitation in the lubricant, caused by the presence of contaminant heavy fuel oil, is prevented or inhibited.

    摘要: A system is provided for use on large vehicles of the type wherein the vehicle frame is supported on vehicle axle assemblies through air bags, and each air bag has a lower end coupled to the lower end of an arm such as a swing arm whose upper end is pivotally mounted on the frame. The height of the air bag is sensed by a pair of tilt sensors, sensing tilt of its location with respect to gravity, and the difference in tilt indicates air bag height. The output of the tilt sensors may be filtered, and a motion detector allows rapid filling or dumping of air bags independent of filtering of tilt sensor signals. Control of the vehicle air suspension can also be based upon inputs from one or more air bag pressure sensors.
