Abstract: A system for detecting a fault condition in a valvetrain of an engine is configured to measure one or more operating parameters associated with the engine and determine if the operating parameters satisfy pre-defined corresponding boundary conditions. If so, a pair of values of at least one performance parameter is measured corresponding to measurement on a first and second bank of cylinders present on the engine. The difference between the pair of values is determined and used to compute at least one measure of variation for the at least one performance parameter in a time segment. If the at least one measure of variation for the at least one performance parameter exceeds a pre-defined limit for the engine, the valvetrain is flagged as faulty.

Abstract: A failure detection device is disclosed. The failure detection device may receive operations data related to operations of a set of parts of a machine. The failure detection device may process the operations data using a condition-based processing technique. The condition-based processing technique may be associated with mapping initial values of data elements of the operations data to binary values based on satisfaction of a first set of conditions by the initial values. The failure detection device may detect a presence of a possible issue with the operations of the set of parts based on a second set of conditions, associated with the binary values and the initial values, being satisfied during a time period. The failure detection device may perform, after detecting the presence of the possible issue, a set of actions related to addressing the possible issue.
