Abstract

Abstract In this research the experimental work carried out for measuring the silencer noise intensity of a turbocharged OM314 DIMLER diesel engine at various engine speeds, namely 1200, 1400, 1600, 1800 and 2000 rpm. At each engine speed, the torque varied from 20 to 100 N.m, in an interval of 20 N.m. In each test, the noise intensity level measured at the exhaust of a dissipative muffler with and without a heat exchanger. The results were analyzed by utilizing the exergy method and irreversibility, based on second law of thermodynamics. The results show, increasing the irreversibility of the dissipative muffler (silencer), when a comparison is made between the silencer with and without heat exchanger at similar operating conditions, causes a significant reduction in noise level.
