Abstract

PURPOSE:To improve the purification performance of CO,HC in supplying the exhaust gas with the air fuel ratio having more than theoretical air fuel ratio and the exhasut gas of air fuel ratio having less that theoretical air fuel ratio to the ternay catalyzer in a mutual manner with on-off suppoy of te secondary air.
