EXHAUST EMISSION CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

PURPOSE:To judge the adsorptive capacity of an adsorber adsorbing and desorbing an unburnt gas ingredient simply and accurately. CONSTITUTION:When an unburnt gas ingredient such as hydrocarbon or the like is made to flow back to an exhaust reflux passage 19, a period CtHC of less than a specified co...

Zusammenfassung:	PURPOSE:To judge the adsorptive capacity of an adsorber adsorbing and desorbing an unburnt gas ingredient simply and accurately. CONSTITUTION:When an unburnt gas ingredient such as hydrocarbon or the like is made to flow back to an exhaust reflux passage 19, a period CtHC of less than a specified coefficient value KHC of the air-fuel ratio compensation efficient K02 is longer than a specified period CtHCREF, normalness in an adsorber 14 is detected by an electronic control unit 5, and likewise, when the period CtHC of less than the specified coefficient value KHC of the air-fuel ratio compensation coefficient K02 is shorter than the specified period CtHCREF, the normalness in the adsorber 14 is detected by the electronic control unit 5 as well.
