Study on Deteriorating Characteristic Analysis on Three-Way Catalytic Convener Used in the Car and Its Control Measures
摘要
Abstract
Based on the model, numerical simulation of temperature and oxygen fields was simulated using CFD software, the relational graph of road haul was exported by leading case and data to processing software after defining function of Pt particles average diameter and response frequency factor, its main deteriorating characteristics of three-way catalytic convener are Pt particles average diameter and response frequency factor. According to above-named causes, some measures were brought to prevent the deterioration of Pt particles average diameter and response frequency factor.关键词
