PROBLEM TO BE SOLVED: To install an engine mount and a turbo supercharger respectively at optimum positions, in a case cylinder heads are inclined.SOLUTION: In each of cylinder heads 6 and 7, a manifold passage is integrally casted inside of a side wall portion, and exhaust ports of three cylinders are collected at a single exhaust outlet at the center. The exhaust outlet has a supercharger-mounting flange portion 25 so that turbo superchargers 31 and 32 are directly mounted thereon. A flange face of the supercharger-mounting flange portion 25 is relatively inclined to center axes of the cylinders corresponding to the inclination of the cylinder heads 6 and 7, and is a vertical face in a state of being loaded on a vehicle. Accordingly, the turbo superchargers 31 and 32 are disposed at comparatively high positions, and disposed in spaces between the exhaust outlet and the engine mounts 14 and 15, respectively. |
