Patent ID: 10066525

Abstract:
An exhaust gas control system includes: a housing, an exhaust gas purification catalyst, and a microwave irradiator. The microwave irradiator is configured to irradiate the exhaust gas purification catalyst with a microwave such that a standing wave that has: a high magnetic field region; and a high electric field region. The exhaust gas purification catalyst includes a carrier substrate and a catalytic substance that purifies the exhaust gas. The catalytic substance is disposed on the carrier substrate. The carrier substrate includes a magnetic body region and a dielectric region. The magnetic body region of the carrier substrate is disposed in the high magnetic field region in the housing. The dielectric region of the carrier substrate is disposed in the high electric field region in the housing. The magnetic body region has a magnetic body that absorbs the microwave. The dielectric region has a dielectric that absorbs the microwave.
