PROBLEM TO BE SOLVED: To uniformalize abrasion and exhaust gas performance in respective cylinders by eliminating variations of intake amount of blow-by gas in accordance with cylinders, and accelerate uniform distribution of the blow-by gas to respective cylinders by utilizing a structure in which EGR gas is returned to an intake passage. SOLUTION: In the blow-by gas returning structure of a multicylinder engine, a reducing passage 52 of blow-by gas and a returning passage W of EGR gas are both connected to a single pipe part 13a before branching out into respective cylinders 21 in an intake passage K. In addition, the reducing passage 52 and the returning passage W are arranged so as to be faced to each other in the single pipe part 13a. COPYRIGHT: (C)2005,JPO&NCIPI
