For engine equipped with dual switch-type oxygen sensors upstream and downstream of the Three-Way Catalyst (TWC), an innovative dual-loop control model of excess air ratio is proposed here. The front oxygen sensor is used to perform PI feedback control of the closed-loop control factor that makes λ ripple periodically in the vicinity of 1. The rear sensor is used to monitor and correct the λ drift...
Because such lots of information as data, personnel, model etc., which are involved during the course of virtual designing and co-simulation, need be managed integratedly, according to the overall system structure of webifying virtual designing and co-simulation, the multidisciplinary integrated management technology is studied, and the system structure of integrated management platform is put forwards;...
