Biodiesel can be used easily as an alternative fuel in diesel engine and is environmentally friendly. In the
present work for prediction of combustion process in a low speed diesel engine (M8/1 Lister), a single-zone
combustion model (Whitehouse-Way) was used. This model was verified by experimental data. Predicted
values of cylinder pressure and heat release rate from this modeling showed good agreement with corresponding
experimental data. Also, the results of the engine short time tests, showed with increasing biodiesel
percentage up to 20 volumetric, same properties such as pressure peak in combustion chamber, exhaust engine
temperature, ignition delay, engine speed, brake and indicatory efficiency were increased. Due to combustion
quality improvement, CO and UHC emissions were decreased, but NOx increased through higher
combustion temperature and consequently higher pressure. Brake specific fuel consumption was minimum
in compound which is economically very important.
