HEAT BLOCKING SYSTEM OF AN EXHAUST MANIFOLD, CAPABLE OF PREVENTING THERMAL STRESS AND VIBRATION FROM BEING TRANSMITTED VERTICALLY TO THE LONGITUDINAL DIRECTION OF A FASTENER

摘要

PURPOSE: A heat blocking system of an exhaust manifold is provided to prevent the vibration and the thermal stress of the engine from being delivered to a heat blocking cover by forming a wave washer between a stainer and a spacer.;CONSTITUTION: A heat blocking system of an exhaust manifold comprises a heat blocking cover(10), a fastener(20), and a spacer(30), and a stainer(40). The fastener couples the heat blocking cover and the exhaust manifold. An inlet hole is formed in the spacer. The stainer is formed between the spacer and the heat blocking cover. A wave washer(50) is formed between the stainer and the spacer. The wave washer absorbs the vibration of the longitudinal direction of the fastener. The stainer comprise a first curvature portion(48) formed on the outer circumference of the third contact part(46).;COPYRIGHT KIPO 2010
