The primary objective of this work is to design new type of silencer with perforated inner pipe and nozzles for reducing the sound pressure level in automobile engine. Initialy, the proposed silencer with perforated inner pipe and nozzles was designed and analyzed by using ANSYS-Fluent (Workbench). In this analysis the effect of number of nozzle, convergence angle and position of nozzles were investigated. Based on the simulation results the proposed silencer with perforated inner pipe and nozzles was fabricated. Meanwhile conventional type silencer (with perforated inner pipe and without nozzle) was also fabricated. Both type of silencer were tested in a Kirloskar single-cylinder water-cooled 10hp diesel engine. The sound produced through the outlet of the silencer was measured using the SPL application on the mobile device. The experimental results shows that the silencer with perforated inner pipe and nozzles was having lower sound level and lower engine's backpressure.
