PURPOSE: An engine is miniaturized and made compact by forming bosses accepting fasteners for fixing cylinder heads in part of a plurality of intake and exhaust passages formed on the cylinder heads fixed to a cylinder block. CONSTITUTION: The diesel engine (10) is provided with a cast block (12) having a pair of cylinder banks arranged in a V-shape and each aligned with a plurality of cylinders (24), and a piston is inserted into each cylinder (24). A cylinder head (34) is fixed to each bank, at least four intake and exhaust passages (46, 48) are formed for each cylinder (24) on each cylinder head (34), and at least one of the intake passages (46) is formed into an S-shape displaced with an inlet (50) and an outlet (54) in the radial direction. Bosses (76) are formed at positions aligned with the inlets (50) on the intake passages (46) to accept fasteners (74) for clamping the cylinder heads (34) to an engine block (12).
