To provide a support system of a purification catalyst box body which can reduce noise generated by vibration transmitted to the purification catalyst box body from an engine main body.SOLUTION: At one side face of an engine main body 2, n(n≥1) pieces of purification catalyst box bodies 3 are oppositely arranged via support devices 4 having vibration-proof members 5. The purification catalyst box bodies 3 and the support devices 4 are arranged at respective n-pieces of positions in which amplitudes of vibration in an opposing direction of the engine main body 2 in an n-th order mode become maximum with respect to left and right directions of the engine main body 2 horizontally orthogonal to the opposing direction being a direction in which the engine main body 2 and the purification catalyst box bodies 3 oppose to each other.SELECTED DRAWING: Figure 2
【課題】エンジン本体から浄化触媒用筐体に伝達される振動により発生する騒音を低減することができる浄化触媒用筐体の支持システムを提供する。【解決手段】エンジン本体2の一側面にn(n≧1)個の浄化触媒用筐体3を防振部材5を有する支持装置4を介して対向配置する。浄化触媒用筐体3及び支持装置4は、エンジン本体2と浄化触媒用筐体3とが対向する方向である対向方向に水平に直交するエンジン本体2の左右方向に関して、エンジン本体2の対向方向の振動のn次モードの振幅が最大となるn個の位置に各々配置される。【選択図】図2
