ABSTRACT

The aim of the present study is to develop a computer code for determining complete cycle, performance parameters and exhaust emissions of diesel engines. For this purpose, a computer program has been used and improved with new assumptions. To compute diesel engine cycle, zero-dimensional intake and exhaust model given by Durgun, zero-dimensional compression, combustion and expansion model given by Ferguson have been used and improved with new assumptions. Using the developed computer program, complete engine cycle, performance parameters and exhaust emissions can be determined easily. The values of the cylinder pressure and engine performance parameters predicted by the presented model matched closely with the other theoretical models and experimental data. Also, this program can be adapted and used practically for various parametric, alternative fuel and water addition studies in diesel engines.
