Title:
PARTICULATE-MATTER PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/124089
Kind Code:
A1
Abstract:
The present invention promotes the aggregation of particulate matter. The following are provided: an electrode provided in the exhaust passage of an internal combustion engine; a power supply that is connected to and applies a voltage to said electrode; an air-fuel ratio detection device that detects or estimates the air-fuel ratio of exhaust emissions flowing through the exhaust passage; and a power control device that makes the power supplied to the electrode from the power supply larger when the air-fuel ratio detected or estimated by the air-fuel ratio detection device is rich than when said air-fuel ratio is stoichiometric or lean.
