Title: Exhaust emission control device of engine
Inventor: OGUMA HAJIME
IPC: F01N3/28
Filed: 2001-06-29
Abstract: PROBLEM TO BE SOLVED: To overcome a problem in an engine having a catalyst converter having a three-way catalyst layer on the surface of an HC adsorbing layer wherein distortion temperature of HC is lower than an activity starting tempera ture of the three-way catalyst layer and thus distorted partial HC is discharged without oxidation in an activating process of the catalyst. SOLUTION: The catalyst converter is provided with a heat transfer suppressing means comprising an intermediate layer or the like for suppressing heat transfer from the three-way catalyst layer to the HC adsorbing layer. Exhaust temperature is controlled so that the three-way catalyst layer reaches an activity temperature before the HC adsorbing layer reaches the HC distortion starting temperature when the three-way catalyst layer does not reach the activity temperature in cold starting time of the engine.

Abstract: PROBLEM TO BE SOLVED: To provide a system at low cost, which is capable of suppressing sufficiently enrichment of an air-fuel ratio by purge while accelerating canister purge. SOLUTION: When an output value of an oxygen sensor is in the vicinity of a theoretical air-fuel ratio and within a range indicating linearity (S101), deviation between an actual air-fuel ratio obtained from the sensor output value and a target air-fuel ratio is calculated (S102).

When the sensor output value is outside the range indicating the linearity, the purge rate is held to a previous value (S106→S107) in an initial time. If the value is successively out of the range, and if it is not more than a rich limit value, the purge rate is r educed (S108→S109), and if the sensor output value exceeds the rich limit value, the purge is stopped (S108→S110).
