Abstract

Problem: In a valve system for OHV-type horizontal opposed type four-cycle internal combustion engine, to contrive large reduction of the weight and size of piston heads at which intake and exhaust valves of the internal combustion engine are disposed. Means of Solution: Valve camshafts (26i, 26e) are provided at crankcase portions (2L, 2R) for supporting a crankshaft(1), of left and right cylinder banks(CB1, CB2) disposed on opposite sides of the crankshaft(1). Intake and exhaust valves (14, 15)provided at cylinder heads (4L, 4R) are opened and closed by pull rods (20i, 20e) operated by the valve camshafts (26i, 26e). <IMAGE>
