PURPOSE:To aim at making improvements in heat-impact resistance, vibro- resistance and distortion proof, by forming a heat insulating layer of exhaust system equipment with insulant powder and inorganic fiber. CONSTITUTION:A heat insulating layer to be formed in an inner surface of exhaust system equipment is made up of mixing inorganic fiber such as glass fiber or the like in insulant powder of hollow ceramic grains or the like. In this connection, the inorganic fiber may be laminated on the top where the insulant powder is stuck to an equipment inner surface. With this constitution, heat-impact resistance, vibro-resistance or the like are improved together with heat resistance and refractoriness and, what is more, separation of the heat insulating layer is preventable. |
