PURPOSE:To simplify a suction passage device in structure, by forming a supercharged air passage solidly inside an engine body, while solidifying a cylinder head with a prechamber of the engine as one body. CONSTITUTION:Supercharged air being compressed by a compressor 11 passes through a supercharged air passage part 30, a lower crankcase 5, a supercharged air passage part 31 of an upper crankcase 6, a supercharged air passage part 32 of a front cylinder head 3f and a supercharged air passage part 33 of a front cylinder cover 4f and then fed to a prechamber 20. A concave designed to be turned to the prechamber 20 is formed on the top surface of the front cylinder head 4f, and a prechamber cover 22 is attached to this concavity. |
