Abstract:
A collector (21) is provided with a collector partition plate (213) for dividing the inner space of the collector into two parts. A resonance pipe (22) is provided with a resonance pipe partition plate (223) for dividing the inner space of the resonance pipe into two parts. A first air intake branch pipe (231) and a fourth air intake branch pipe (234), which are located at both ends of a row of cylinders, are connected to one collector chamber (211) separated by the collector partition plate. A second air intake branch pipe (232) and a third air intake branch pipe (233), which are located at the center of the row of cylinders, extend toward the collector from the same direction as the first air intake branch pipe and the fourth air intake branch pipe, pass through between the collector and the resonance pipe, and are connected to the other collector chamber (212).
