Abstract
An air intake manifold may include an air intake tube that communicates with a plurality of cylinders of an internal combustion engine and a blow-by gas passage that guides blow-by gases of a crankcase of the internal combustion engine to the air intake tube. The air intake tube may include an intake air guide-in part into which intake air is guided, a plurality of branch tubes, a mounting part, and a valve disposed inside the branch tubes. The blow-by gas passage may include a blow-by gas guide-in part into which the blow-by gases are guided, a blow-by gas guide-out part, a blow-by gas flow path part disposed between the blow-by gas guide-in part and the blow-by gas guide-out part, and a connecting passage part that branches from the blow-by gas flow path part and connects to the branch tubes at a position of the blow-by gas guide-out part.
