Abstract：
In this thesis,the physicochemical properties of four kinds of monolith cordierite ceramic carriers are compared by means of XRD,TSP,and BET. They are different in crystallinephase,specific surface area,water absorption property,and thermal shock parameter. Considered the economical target,a kind of carrier with good properties and low price are chosen. A number of perovskite\|type catalyzer was made and tested in an electrically fuel\|injection automobile. Addition a little precious metal can effectively improve its reactivity in the formulation of the perovskite\|type catalyzers. The resistance to low leaded fuel of the precious metal in the three\|way catalyzers is worse than that of perovskite\|type one.
