Abstract: A plurality of passages disposed in parallel are formed in an air cleaner interposed in an intake system of an engine. An intake control valve for opening/closing the a passage having a large cross-sectional area is provided in the air cleaner. An actuator for closing the intake control valve in a low speed rotational range of the engine and opening the intake control valve in a high speed rotational range of the engine is connected to the intake control valve.

Abstract: A poppet valve in an internal combustion engine comprises a valve head and a valve stem. On a valve face of the valve head, a hardened layer of dendrites in which crystals are directed from the inside to the surface is formed, thereby increasing wear resistance of the valve face without cladding.
