In the exhaust structure of the light-weight portable generator set, the first-stage silencer is fixed at the upper part of one side of the engine, the second-stage silencer is fixed at the lower part of one side of the engine, and the second-stage silencer is positioned below the first-stage silencer. Through the setting of this structure, one-level silencer and second grade silencer all set up same one side at quick-witted incasement, compact structure.

In the exhaust structure of the light-weight portable generator set, the first-stage silencer is integrated on the engine. Through the arrangement of the structure, the first-level silencer is directly integrated on the engine, the first-level silencer is firm and stable on the engine, the assembly process is reduced, and the convenience of assembly of the generator set is improved.

In the exhaust structure of the light-weight portable generator set, the engine is provided with a mounting frame, and the secondary muffler is fixed on the mounting frame. Through the arrangement of the structure, the secondary muffler is convenient, stable and firm to install on the engine.

In the exhaust structure of the light-weight portable generator set, the exhaust joint is arranged in the through hole in a penetrating mode. Through the arrangement of the structure, the waste gas coming out of the exhaust joint is directly discharged out of the case.

Compared with the prior art, the utility model discloses a portable generating set's of light weight exhaust structure has following advantage: exhaust waste gas of the gas vent of this structure engine carries out the amortization in proper order through one-level silencer, blast pipe and second grade silencer and falls and make an uproar, and waste gas outwards discharges from exhaust joint, one-level silencer and second grade silencer integration are at generating set's quick-witted incasement, make generating set possess better amortization and fall the performance of making an uproar, compare with prior art, make generating set need not external silencer again, the structure of generating set has been simplified, generating set compact structure, and make things convenient for the convenience of generating set transport.
