Latest Patents

Vangilder holds a patent for a catalytic converter diagnostic system. This diagnostic tool includes a series of enabling conditions for modeling temperature and operational stability of the treatment means. It features first and second stage tests that are alternately applied on an engine air/fuel ratio cycle-by-cycle basis. This method utilizes post-converter oxygen sensor information to assess the performance of the treatment means. When the performance is diagnosed as being degraded, the first stage is disabled, and the more statistically rigorous second stage is activated. This two-phase approach is designed to closely scrutinize converter performance while providing false alarm protection.
