Abstract: A controller includes at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, cause the at least one processor to: perform operations comprising: determining a concentration of a plurality of wear metal particles in a lubricant for an engine system; determining a filtered concentration of the plurality of wear metal particles using a baseline concentration of the plurality of wear metal particles; setting a diagnostic threshold based on the filtered concentration of the wear metal particles; and, responsive to determining that the concentration of the wear metal particles exceeds the diagnostic threshold, providing a notification.

CPC classification number: F02M31/205 , F02B33/44
Abstract: Control of an internal combustion engine system in response to a condensation condition associated with a charge air cooler is disclosed. One or more operating parameters of the internal combustion engine are monitored to the control charge air cooler coolant inlet temperature to keep the charge temperature above the estimated dew point to reduce or prevent condensation upstream of the intake manifold.
