Internal combustion engine irrigation and drainage air type component

摘要

(57) Abstract Topic Stability and improvement and acoustic material fiber of exhaust gas purification performanceBombardment of maintaining, improvement and sound-absorbing degradation of disconnection and the discharge with the vibrationEndurance and light weight conversion of prevention and exhaust air component. Solutions The for internal combustion engine as an exhaust gas purification catalytic converter substrateThe metal where the exhaust air component was formed to flexible pipe condition or sheet formSintering body 1 of the fiber is. The internal combustion engine irrigation and drainage air as a acoustic materialThe type component is the sintering body of the metallic fiber. Porous flexible pipe and that polyThe glass fiber outside the hole flexible pipe and it possesses the sound-absorbing section which consists ofIn the internal combustion engine irrigation and drainage air type component, the porous flexible pipe and the glass fiberThe sintering body of the metallic fiber was laid out between maintaining. Aforementioned metal fiberThe sintering body of maintaining, is the iron based alloy.
