EXHAUST MANIFOLD HAVING IMPROVED NVH CHARACTERISTICS

摘要

An exhaust manifold and method of manufacturing the same is provided that includes at least one tube within shells of an exhaust manifold The tube limits fluid communication from the tube into the shells of the exhaust manifold An inlet flange is connectable to the exhaust manifold and is attachable to a cylinder head of a combustion engine Exhaust gases expelled from the cylinder head are transmitted into the exhaust manifold At least a portion of the exhaust gases pass through the tube The exhaust manifold reduces NVH and cures emission control issues.
