Title:
PARTICULATE MATTER DETECTION SENSOR
Document Type and Number:
WIPO Patent Application WO/2016/175022
Kind Code:
A1
Abstract:
A particulate matter detection sensor according to the present invention is provided with an element body part for detecting the amount of particulate matter included in exhaust gas discharged from an internal combustion engine. One end surface of the element body part is provided with a deposition reception part on which a portion of the particulate matter is deposited and at least one pair of detection electrodes disposed on the deposition reception part. The particulate matter detection sensor is configured so as to vary electrical signal output according to variation in the electrical characteristics between the pair of detection electrodes resulting from the deposition of particulate matter on the deposition reception part. The deposition reception part has a collection recess formed thereon that is recessed from the end surface on which the deposition reception part is formed.
