97103091 Development of cumulative and availability rate balances in a multi-cylinder turbocharged indirect injection diesel engine Rakopoulos, C. D. and Giakoumis, E.G. EnrrXy Cor1vers. M~r?ll. lY97. 38, (4). 347-369. A single-zone thermodynamic model was used to analyse a multi-cylinder turbocharged Diesel engine from a second law analysis point of view. For this purpose, a comprehensive digital computer program is developed that incorporates sub-routines to simulate, among other things, combustion. heat transfer, indirect fuel injection. mass flow through valves, turbocharger and aftercooler behaviour. and real multi-cylinder engine action. This is tested favourably against relevant data from an experimental investigation conducted at the authors' laboratory. A second law analysis was performed in all parts of the engine. The analysis provides the proper evaluation of every component's irreversibilities. The model is applied to a six-cylinder, turbocharged and aftercooled, indirect injection, four-stroke, medium-high speed diesel engine, installed at the authors' laboratory. The results demonstrate that the second law analysis offers a more spherical and comprehensive insight into the processes occurring in a diesel engine than its traditional first law counterpart.
