ENGINE WITH SUPERCHARGERS

摘要

PROBLEM TO BE SOLVED: To provide an engine with superchargers capable of curbing an increase in pressure loss generated in piping in which exhaust gas discharged from the superchargers flows.SOLUTION: An engine with superchargers comprises: a pair of superchargers with respective exhaust ports 32 arranged opposite to each other; an exhaust flow direction changing piping at one side 12 which guides a flow of exhaust gas at one side E1 discharged through an exhaust port at one side 32a to a side closer to the exhaust port at the other side 32b than a center section C of the pair of the superchargers and then changes a flow direction thereof to a discharge direction Y while swirling the flow thereof around an axial center of a junction pipe 14; an exhaust flow direction changing piping at the other side 13 which guides the flow of the exhaust gas at the other side E2 discharged through the exhaust port at the other side 32b to the side closer to the exhaust port at one side 32a than the center section C and then changes the flow direction thereof to the discharge direction Y while swirling the flow thereof around the axial center of the junction pipe 14; and the junction pipe 14 which combines the flows of the exhaust gas at one side E1 and the exhaust gas at the other side E2.SELECTED DRAWING: Figure 4
