Abstract
The invention discloses a silencer for a single cylinder diesel capable of reducing noise and emission and a manufacturing method of the silencer. The silencer comprises a pipe connector, an upper shell, a lower shell, an upper silencing net, a lower silencing net, a filtering body, vibration isolation pads, an exhaust pipe and a sound absorbing material layer. One end of the pipe connector is connected to an exhaust elbow pipe of a cylinder cover of an engine through threads, and the other end of the pipe connector is fixedly connected with the lower shell. A groove is formed between the lower shell and the upper shell. The exhaust pipe is in necking connection with a pipe orifice of the upper shell. The upper silencing net is arranged at the upper end of the filtering body. The lower silencing net is arranged at the lower end of the filtering body. The two ends of the filtering body are provided with the vibration isolation pads extending outwards correspondingly. The filtering body, the upper silencing net and the lower silencing net are arranged in the groove between the upper shell and the lower shell. The inner wall of the upper shell, the inner wall of the lower shell and the inner wall of the exhaust pipe are filled with the sound absorbing material layer. The method that a ventilation net section three-stage step-by-step magnified silencing mode is adopted, and airflow is subjected to big and small hole alternate silencing and sound absorbing material combined silencing is adopted, and thus noise can be effectively reduced.
