The utility model relates to an engine silencer and a generator set. The engine silencer comprises a barrel, an exhaust pipe and a plurality of air inlet pipes. Wherein a converging cavity and a plurality of buffer cavities which are relatively independent are formed in the cylinder body, the plurality of air inlet pipes are respectively communicated with the plurality of buffer cavities in a one-to-one correspondence manner, and the exhaust pipe is communicated with the converging cavity; communicating channels are arranged between the multiple buffer cavities and the converging cavity in a one-to-one correspondence mode. The plurality of buffer cavities and the converging cavity are sequentially arranged in parallel along the exhaust direction; the exhaust resistance is reduced, the backpressure of the silencer is reduced, and the power is improved while broadband silencing is facilitated; meanwhile, the problems that the joint of the double air inlet pipes of the silencer becomes red, the back pressure of
