Abstract: A method includes: receiving system data corresponding to an engine system. The system data includes a plurality of remaining useful life (RUL) values with each RUL value associated with a component of the engine system. The method further includes: comparing a first RUL value to a service interval threshold; generating a near-term service recommendation including a first list of components that correspond to each RUL value that are less than or equal to the service interval threshold; generating an extended term service recommendation including a second list of components and a downtime prediction; generating a coordinated service recommendation by dynamically populating one or more fields of the coordinated service recommendation based on the near-term service recommendation and the extended term service recommendation; and providing the combined service recommendation to a user device.

Abstract: Systems and methods for determining a remaining useful life (RUL) of a component of an engine system are provided. A method includes: receiving component data comprising sensor data corresponding to a component and engine data; pre-processing the component data by removing a first set of sensor data values that correspond to a first set of engine data values of the engine data; aggregating the pre-processed component data by grouping a second set of sensor values of the sensor data; determining a RUL for the component based on a RUL model that correlates at least a portion of the aggregated data to RUL values; adjusting the RUL based on at least one of detecting a service event or determining that one or more sensor data values of the sensor data are outside a predetermined range of values; and providing the RUL to a user device.

Abstract: Spark plugs are disclosed that include electrode arrangements to improve the charge flow into and out of the annular volume around the insulator nose and a pre-chamber volume of a pre-chamber device, thus directing a purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device.

Abstract: A combustion pre-chamber assembly includes pre-chamber device body defining an annular plenum that is in fluid communication with the at least one bore that extends through the spark plug shell. The annular plenum is also in communication with at least one purging passage that extends from the annular plenum to an end surface of the pre-chamber device body. Residual exhaust gases in the annular volume of the spark plug are purged by fresh charge flow from the main combustion chamber as the piston approaches top dead center. The fresh charge flow that is provided to the annular plenum through the at least one purging passage and into the annular volume of the spark plug through the at least one bore through the spark plug shell.
