Abstract
A catalytic converter is obtained that can suppress deterioration in insulating ability between electrode members that is caused by moisture within exhaust. Insulating layers are provided at peripheries of electrode rods that are for energizing a catalyst carrier, and the electrode rods are insulated from a case tube. The catalyst carrier is structured of a material whose temperature rises due to application of voltage. Temperatures of the insulating layers are raised by applying voltage from a power supply to the catalyst carrier.
Claims6
A catalytic converter comprising:
- a case tube that is mounted to an exhaust pipe and through an interior of which exhaust flows;
- a catalyst carrier that is provided at the case tube, that carries a catalyst for purifying exhaust that is exhausted from an engine, and that is heated by energization;
- a pair of electrode members that pass through the case tube, are made to contact the catalyst carrier, and are for energizing the catalyst carrier;
- an insulating member that is disposed between the case tube and at least one of the electrode members, that insulates the electrode member from the case tube, and that generates heat due to application of voltage;
- and
- a control device that controls energizing of the catalyst carrier and application of voltage to the insulating member.
