摘要： It is an object of the present invention to provide an exhaust gas purifying catalyst filter which has enhanced soot collection performance without increasing pressure loss caused by the formation of a catalyst layer in a partition wall of a wall flow type substrate.
A gasoline engine exhaust gas purifying catalyst filter for purifying exhaust gas of a gasoline engine includes: a wall flow type substrate in which an introduction-side cell having an open exhaust gas introduction-side end, and a discharge-side cell adjacent to the introduction-side cell and having an open exhaust gas discharge-side end are defined by a porous partition wall; and a catalyst layer formed in a pore of the partition wall. An absolute value of a maldistribution degree of the catalyst layer formed in the pore of the partition wall is 4.50 or less. A wash coat amount, excluding a mass of a platinum group, of the catalyst layer formed in the pore of the partition wall, is 40 g/L or more and 50 g/L or less. The catalyst layer formed in the pore of the partition wall is a single layer. The catalyst layer is free of Ba.
