  • Patent number: 10782280
    Abstract: There is described herein methods and systems for evaluating a condition of an engine. Fluid sample data obtained from an engine is received and weights are assigned to different data sets of the fluid sample data. The data sets correspond to one or more classes of materials into which particles of the fluid sample are sorted. A characterizing sample signature of the engine is generated based on the data sets. The sample signature is compared to a plurality of reference signatures obtained from reference engines belonging to a common family with the engine. A selection is made from the reference engines for those having a difference between a corresponding signature and the sample signature below a threshold. Historical engine data of the selected reference engines is output as a basis for evaluating the condition of the engine.

  • Publication number: 20140083172
    Abstract: In a method for determining an ageing state of lubricant which comes into contact with a metallic surface in a machine to be lubricated, a metal ion content or a change over time of a metal ion content in the lubricant is determined. The metal ion content can be determined by a measuring sensor which is disposed in the machine or disposed in a lubricant line connected to the machine.

  • Patent number: 8640528
    Abstract: The present invention relates to a method of determining a lubrication parameter indicative of a lubrication condition of an oil-lubricated rolling element bearing. The method comprises measuring high-frequency structure-borne acoustic emissions generated by asperity contact between rolling contact surfaces of the bearing, to provide a measured signal. The emitted acoustic energy is then extracted from the measured signal and the lubrication parameter is determined from the acoustic energy. The determination is made on the basis of a power-law relation between acoustic energy and the lubrication parameter.

  • Patent number: 8614588
    Abstract: Fuel contamination in oil is measured by using a sensor in contact with oil whereby fuel intrusion into the oil will change the electrical, mechanical, and/or chemical properties of the material as compared to the same electrical, mechanical, and/or chemical properties of the material when in contact only with mineral or synthetic oil only. The oil quality sensor provides real-time feedback so that an oil monitoring system can actively remove contaminates and/or increase an additive package as necessary.

  • Patent number: 8593162
    Abstract: An object of the invention is to provide a fuel-aspect sensor having higher detection accuracy. A first electrode is inserted into a hole formed in a first housing member. A cylindrical second electrode is inserted into and firmly fixed to the first electrode by a cylindrical insulating member. A first elastic member, for example, made of rubber, is arranged between the first electrode and a second housing member. The first electrode has a large-diameter portion, which is biased by the first elastic member toward a sealing surface formed on an inner wall of the hole, so as to fluid-tightly seal a space between the first electrode and the second housing member.

  • Patent number: 8540869
    Abstract: A method for forming a finished lubricant comprises selecting a target high temperature viscosity for the finished lubricant. A target high temperature viscosity for a base oil blend is selected. The target high temperature viscosity for the base oil blend is less than the target high temperature viscosity for the finished lubricant. At least two base oils from at least three viscosity grades of base oils are selected and mixed to form a base oil blend that meets the target high temperature viscosity for the base oil blend. The base oil blend is mixed with performance additive package and viscosity modifier to provide a finished lubricant that meets the target high temperature viscosity for the finished lubricant. The at least two base oils for the base oil blend having the target high temperature viscosity are selected such that less viscosity modifier is needed to meet the target high temperature viscosity of the finished lubricant.
