INTAKE MANIFOLD CAPABLE OF PREVENTING AIR CURRENT NOISE FROM BEING GENERATED BY AIR FLOWING THROUGH AN ISCA AIR PASSAGE

摘要

PURPOSE: An intake manifold is provided to prevent air current noise from being generated by air by installing an air current noise preventing unit is formed in an ISCA air passage.;CONSTITUTION: An intake manifold comprises an air current noise preventing unit(143). The air current noise preventing unit is formed on an air passage(141) of an ISCA(Idle Speed Control Actuator,140) connected to the surge tank. The air current noise preventing unit prevents air current noise from being generated by air passing through the air passage. The air current noise preventing unit is formed in the shape of a passage on the outer surface of the curved portion of the ISCA air passage. The air current noise preventing unit has smaller diameter than the diameter of the ISCA air passage.;COPYRIGHT KIPO 2010
