ELECTRICALLY HEATED CATALYST DEVICE

摘要

PURPOSE:To provide an electrically heated catalyst device enabling the improvement of an exhaust purification factor. CONSTITUTION:A catalyst 2 is disposed in a case 1 to be an exhaust passage, and heated parts (non-jointed areas 11) are formed at part of the catalyst 2 and heated by current application. A stream fairing catalyst 12 is disposed upstream of the catalyst 2 in the case 1. Inward louvers 14a are formed at the outer peripheral area 15 of the stream fairing catalyst 12, and outward louvers 14b are formed at the center area 16. The exhaust gas drifts toward the heated parts (non-jointed areas 11) by the louvers 14a, 14b of the stream fairing catalyst 12, and the flow of exhaust gas is concentrated onto the heated parts.
