Abstract: PURPOSE: COP(catalyst overheat protection) area is decided in reference of an exhaust gas temperature and a catalyst temperature to adjust fuel amount, thereby improving air fuel ratio. CONSTITUTION: A method for deciding fuel amount feedback control comprises step of deciding whether an exhaust gas temperature is over a certain level. If the exhaust gas temperature is not over the level, it is decided as an air fuel ratio control area, and a feedback control using an oxygen sensor is carried out. If the exhaust gas temperature is over the level, it is decided as a COP area, and mapped fuel amount is injected. If the mapped fuel amount is injected, it is decided whether the exhaust gas temperature is over a certain level again. If then, fuel is more injected, and if not, the fuel is reduced.
