Title: Exhaust emission control device for internal combustion engine
Inventor: YAMASHITA TETSUYA
IPC: F02D41/02
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To accurately enrich a mixture while no excessive enrichment by correcting the total amount of SOx when the air-fuel ratio in exhaust gas is lean based on the permeability of SOx in an NOx absorbent for the enrichment process depending on the corrected total amount of SOx. SOLUTION: On the basis of the output from an engine running condition detection means 51, a lean/rich decision means 52 calculates a correction coefficient K based on its map. If K<1.0 where the decision means has judged a lean mixture combusted, a total NOx amount estimation means 53 calculates the total amount of NOx that an NOx absorbent absorbs. If the total absorbed NOx amount is of a predetermined value or above, an NOx emission means 58 enriches the air-fuel ratio in exhaust gas and emits the NOx. In the above judgment, a total SOx amount estimation means 63 controls the amount of SOx based on the amount of SOx that the NOx absorbent absorbs such that the SOx absorbed by the NOx absorbent is emitted for the enrichment process.
