AN IMPROVEMENT OF PART LOAD PERFORMANCE OF DIESEL-ENGINES OPERATING AT CONSTANT-SPEED CONDITIONS

This paper discusses the possibility of improving the part load perfor mance of diesel electric turbocharged engines operating at constant sp eed conditions. A sequential turbocharged system is proposed, where th e compressors are connected in series. The study focused on two turboc harged diesel-electric generating sets existing at Ameria Refining Com pany in Alexandria, Egypt. The results of the prediction showed that, at part load, both the maximum pressure and temperature were increased , and the brake specific fuel consumption was reduced considerably (by about 10 per cent).
