Abstract: Systems, devices and methods for diagnosing malfunctioning in a crankcase ventilation (CCV) system are provided. A controller includes a processor and a memory storing instructions that cause the processor to: receive a plurality of pressure values including (i) a first pressure value indicative of a pressure of fluid flowing from a crankcase to a breather assembly of a system, (ii) a second pressure value indicative of a pressure of fluid flowing through a first tube coupled to the breather assembly, and (iii) a third pressure value indicative of a pressure of fluid flowing through a second tube coupled to the breather assembly; determine a pair of pressure differences based on the first pressure value, the second pressure value, and the third pressure value; and detect a malfunctioning in the CCV system based on the pair of pressure differences.

Abstract: A computing system is structured to receive operating data provided by a telematics circuit associated with a remote engine. The operating data comprises information provided by at least one sensor and/or at least one actuation command. The computing system is structured to determine, based on the operating data, a plurality of field-replaceable units (FRUs) associated with the operating data. The computing system is structured to generate a computer-based simulation corresponding to at least one degradation level for an FRU from the plurality of FRUs, identify a most probable failure, and rank the computer-based simulations across the plurality of FRUs. The computing system is structured to generate an electronic notification comprising data associated with the most probable failure and transmit the electronic notification to a computing device.

Abstract: Systems, devices and methods for diagnosing malfunctioning in a crankcase ventilation (CCV) system can include a controller receiving a plurality of pressure values. The plurality of pressure values include a first pressure value indicative of pressure of gases flowing between a crankcase and a breather assembly, a second pressure value indicative of pressure of gases flowing through a CCV tube from the breather assembly, and a third pressure value representing pressure of gases in a tube connected to the CCV tube. The controller can calculate a pair of pressure differences including a first pressure difference between the first pressure value and the second pressure value and a second pressure difference between the first pressure value and the third pressure value. The controller can detect a malfunctioning or defect in the CCV system based on the pair of pressure differences falling within a predefined clustering region.
