This paper presents a one-dimensional (1-D)/three-dimensional (3-D) simulation methodology for uprating a diesel engine to reduce production costs and improve fuel economy. The case study is carried out for a baseline multicylinder direct injection (DI) naturally aspirated (NA) diesel engine of 2945 cc, which meets the Central Pollution Control Board (CPCB)-II emission regulations and is used in a 25 kVA genset application. An uprated version of this NA engine is designed to replace a 30 kVA genset turbocharged engine, eliminating the expense of the turbocharger while reducing fuel consumption. The 1-D computational model was calibrated on the 25 kVA base engine and produced a good agreement with the airflow rate, power, brake-specific fuel consumption (BSFC), cylinder pressure, and oxides of nitrogen (NOx) emission levels.
