Latest Patents
One of Holcombe's latest patents is a method and system for positive crankcase ventilation (PCV) diagnostics. This innovative method involves generating an estimated crankcase pressure at the location of a crankcase pressure sensor based on both a nominal model and a faulted model of a PCV system. The method also includes diagnosing a PCV system component by comparing the estimated crankcase pressure with input from the crankcase pressure sensor. If a fault is detected, the system triggers a sensor degradation indicator. Another significant patent is for a cylinder block baffle designed to separate oil from crankcase gases. This oil separation baffle is strategically mounted in an oil gallery of an internal combustion engine, allowing crankcase gases to flow through while effectively returning oil to the crankcase.
