Patent number: 11226358Abstract: A damage analysis and control system is disclosed. An example process may include receiving a data set of measurements associated with a period of operation of a power system. The data set of measurements may identify a frequency that the power system is in an operating state during the period of operation, and the data set of measurements may identify a frequency of damage measurements associated with the operating state. The process may include determining, using a damage model and the data set of measurements, a damage score for the operating state during the period of operation of the power system. The process may include determining that the damage score satisfies a threshold damage score associated with the damage model and performing an action associated with the power system based on the damage score satisfying the threshold damage score.Type: GrantFiled: February 27, 2019Date of Patent: January 18, 2022Assignee: Caterpillar Inc.Inventors: Sylvain Charbonnel, Frank Lombardi

Publication number: 20210025342Abstract: A method for controlling an internal combustion engine system including a particulate filter includes receiving a desired output for an internal combustion engine and receiving sensor information including information indicative of a quantity of soot in the particulate filter. The method includes calculating a plurality of sets of engine performance values based on respective sets of candidate control points, each set of engine performance values including a soot change rate at which the quantity of soot changes over time and determining whether the soot change rate satisfies a soot change rate limit that requires an increase in the quantity of soot in the particulate filter.

Patent number: 10851725Abstract: A fuel content detection system is disclosed. The fuel content detection system may include an engine control module (ECM) to receive a measurement of a parameter. The parameter may correlate with an amount of a substance in a fuel that is being consumed in an engine. The ECM may determine an estimation of the parameter based on a model. The model may use a predetermined value associated with the amount of the substance, and the engine may be configured to consume a designated type of fuel that includes an amount of the substance that corresponds to the predetermined value. The ECM may determine, based on the estimation and the measurement not being within a threshold range, that the fuel is not the designated type of fuel and perform an action associated with the engine.Type: GrantFiled: December 18, 2018Date of Patent: December 1, 2020Assignee: Caterpillar Inc.Inventor: Sylvain Charbonnel
