Abstract
A system for sensing soot of a diesel engine includes a combustion element which is a porous ceramic structure and to which a catalytic substance that is combustion-reacted with the soot is fixed, a comparison element which is the porous ceramic structure and to which a stable substance that is not combustion-reacted with the soot, and a detection section for detecting the temperatures of the combustion element and the comparison element and for deducing the soot formation amount among exhaust gas by using the temperature difference of the respective element.
