Latest Patents

Fournelle's latest patents include a "Method for Diagnosing a Vacuum Actuator" and a "Method and System for Variable Cam Timing Device." The first patent describes methods and systems for diagnosing degradation of a vacuum actuator in an engine system. This method involves indicating degradation based on an estimate of air flow into and out of a vacuum reservoir. The estimate considers air flow generated by an aspirator in the intake system, the actuation of the vacuum actuator, and any leakage during the actuator's operation. The second patent focuses on improving phaser positioning control in an engine with a cam torque actuated variable cam timing phaser. This innovation reduces inaccuracies caused by inadvertent movements of the spool valve and phaser, while also enhancing the consistency and robustness of phaser commands through improved spool valve mapping.
