Title: Catalyst for cleaning exhaust gas
Inventor: SAIKI MOTOHISA
IPC: F01N3/18
Filed: 2000-12-25
Abstract: PROBLEM TO BE SOLVED: To efficiently reduce and clean occluded NOx by short-time rich spiking. SOLUTION: The pores of a coat layer are formed so that pores with a pore size of 0.1-20 μm occupy 60% or more of the whole pore volume and pores with a pore size of 10-20 μm occupy 20% or more of the whole pore volume.
