VIBRATION TRANSMISSION CHARACTERISTICS ANALYZER FOR ENGINE BLOCK, AND VIBRATION TRANSMISSION CHARACTERISTICS ANALYSIS METHOD

摘要

PROBLEM TO BE SOLVED: To analyze the vibration transmission characteristic, in response to the operating state of an actual engine.;SOLUTION: This vibration transmission characteristics analyzer for an engine block comprises an exciting device 130, that is connected to a knock sensor mounting hub 163 disposed in a cylinder block 161 and excites the engine block 160 only for a period (t), defined as the duration of vibration when knocking actually occurs; a cylinder block vibration detecting sensor, arranged on the inner surface of a cylinder bore of the cylinder block 161; and a cylinder head vibration detecting sensor, arranged in a plug hole disposed in a cylinder head 162.;COPYRIGHT: (C)2008,JPO&INPIT
