Abstract

An exhaust passage includes first (not visible, behind 53 and 7) and second (8) purifying devices, and a plurality of independent passages (51). The first and second purifying device are arranged in this order in a flow direction of exhaust gas at a height lower than exhaust port opening ends. The plurality of independent passages (51) are fixed as to be in communication with the respective exhaust port opening ends. First (5) and second (7) connecting passages are provided in the exhaust passage. The first connecting passage (5) connects the respective exhaust port opening ends to an upstream end of the first purifying device. The second connecting passage (7) connects a downstream end of the first purifying device to an upstream end of the second purifying device (8). An EGR pipe (41) connects the second connecting passage (7) to an engine exhaust-side surface (1H) at a position higher than the first purifying device.
