Turbocharger Matching and Assessments of Turbocharger Effect on a Diesel Engine based on One-Dimensional Simulation

The aim of this paper is to choose the convenient turbocharger for the OM355 naturally aspirated diesel engine and turn it to a turbocharged one. For this, 1D1 computer simulation code is used and simulation results are validated with experimental measurements. Finally, by selecting a proper turbocharger, engine power increases about 50% and specific fuel consumption decreases about 4%. Moreover, effects of exhaust manifold geometry and ambient condition on performance parameters of the turbocharged diesel engine are investigated.
