INTAKE MANIFOLD HAVING AN ADVANCED PCV GAS UNIFORM DISTRIBUTING FUNCTION AND CAPABLE OF UNIFORMLY DISTRIBUTING BLOW-BY GAS TO EACH CYLINDER OF AN ENGINE

摘要

PURPOSE: An intake manifold having an advanced PCV gas uniform distributing function is provided to uniformly distribute blow-by gas, which flows in the plenum chamber through PCV nipple, to each intake runner.;CONSTITUTION: An intake manifold having an advanced PCV gas uniform distributing function comprises a throttle body(20), a plenum chamber(30), a plurality of intake runners(40), and a gas discharge port(50). The throttle body is connected with a main body(10) and transfers the air mixture generated from a vaporizer(3). The plenum chamber is formed in the inner part of the main body and functions as a temporary reservoir for the air mixture provided through the throttle body. PCV gas is guided in the plenum chamber from a combustion chamber of an engine(5). A plurality of intake runners is formed in a streamlined shape to uniformly supply the air mixture of the plenum chamber to a plurality of combustion chambers. The gas discharge port is arranged on the plenum chamber and guides the PCV gas to be uniformly flowed in the intake runner. The gas discharge port is made of a hollow body, an inlet port, and a guide plate. The inlet port is formed to make one side of the body part open and guides the inflow of PCV gas. The guide plate is arranged on the other side of the main body, and a guide projection is projected on the guide plate.;COPYRIGHT KIPO 2011
