Abstract

PURPOSE: To eliminate dispersion in the negative pressure of intake air for every cylinder and stabilize combustion by mutually connecting the downstream side of the throttle valve of the intake path for cylinders facing each other in a pair of cylinder groups for a V-shaped engine by communication paths.
CONSTITUTION: In a 4-cylinder V-shaped engine for autobicycle, a pair of cylinder groups, consisting of two cylinders 9 and 10 and two cylinders 11 and 12 arranged along the direction of crack shaft are arranged in a V-shape at 90° to each other, and the opening time of the suction discharge valves for the cylinders 9W12 is overlapped under a specific relationship. In this case, suction ports 21 and 23 and suction ports 22 and 24 of the cylinders, whose suction valves' opening or closing times are not overlapped, of the cylinders 9 to 12 are connected to each other by communication paths 34, making up of a communication port 35 and a communication pipe 36 formed in cylinder heads 18 and 19.
