Abstract: The article reports the experimental and theoretical results for an engine working with petrol 95 as a fuel. The theoretical part of this work uses a multi-zone model in order to predict engine performance and NO emissions in a spark-ignition engine. The gas exchange process is calculated by one dimensional isentropic flow through a nozzle. During combustion, 11 products are obtained by chemical equilibrium and Nitric Oxide (NO) formation is calculated by the extended Zeldovich mechanism. The results of the computer multi-zone model are compared with the experimental data. The calculated values for pressure and NO emissions show good agreement with the experimental data. The multizone formulation developed here indicates that the use of 10 burned zones are likely to be sufficient for the accurate prediction of NO emission from SI engines.
