Title:
吸気混合ガス導入構造
Document Type and Number:
Japanese Patent JP4497206
Kind Code:
B2
Abstract:
Exhaust gas inlets for introducing exhaust gas from an EGR pipe, on the right bank side, and exhaust gas inlets for introducing exhaust gas from the EGR pipe, on the left bank side, are both formed in low-pressure regions. The exhaust gas inlets are formed at positions where the pressure of the intake air flowing through branch pipes on the right bank side and the pressure of the intake air flowing through branch pipes on the left bank side are both low and substantially equal. Accordingly, exhaust gas is introduced evenly into cylinders in the right and left banks. These inlets are not formed at positions in a common intake passage from which branch paths branch off, that is, positions upstream of a surge tank. Accordingly, the response to introduction of exhaust gas is not deteriorated but is maintained.
