Turbocharged engine for a vehicle, vehicle equipped therewith, and corresponding method

摘要

Two turbochargers 3, 4 are arranged vertically near a one side of a crankshaft direction at a one-side face of an engine body 2 so that the large-size turbocharger 4 is located above the small-sized turbocharger 3, and an exhaust-gas purification device 5 is arranged an open space made on the other side of the crankshaft direction so that its exhaust inlet is located above and its outlet is located below. Accordingly, the turbochargers 3, 4 and the exhaust-gas purification device 5 can be arranged compactly and the layout of some devices around the engine can be facilitated.
