Abstract
A motor vehicle intake muffler duct is formed by integrally bonding an upper duct, a lower duct and a separator interposed between them. Three airways are formed between the upper duct and the separator, seven muffler chambers are formed between the lower duct and the separator, and the airways and the muffler chambers are communicated with each other through vent holes which are formed in the separator. An intake muffler duct in which multiple muffler chambers are integrated with the airways, can be formed from only three components, which are an upper duct, a lower duct and a separator, and moreover although it has a compact structure, it is possible to reduce the intake noise effectively.
Claims7
A motor vehicle intake muffler duct for introducing air to the engine of a motor vehicle and reducing intake noise, said muffler duct comprising a flattened upper duct, a flattened lower duct, a separator positioned between said upper duct and said lower duct, an air inlet and an air outlet, an airway between said air inlet and said air outlet, said airway being formed between said upper duct and said separator, at least two muffler chambers formed between said lower duct and said separator, at least one partition extending between said lower duct and said separator for separating said muffler chambers, and at least one vent hole formed in said separator for communicating said airway and said muffler chambers with each other.
