This paper deals with a mathematical model of the compression, combustion and expansion processes of hydrogen fueled spark ignition engines for lean operation. A two-zone model has been developed and a semi empirical turbulent flame speed expression is used for the combustion processes. The model predicts the performance and NOx emissions of the hydrogen fueled engine. The NOx emissions were determined by integrating the chemical rate equations resulting from the extended zeldovich mechanism over the boundary conditions determined by the cycle analysis. Dissociation is also taken into account whenever the gas temperature exceeds 1600 K.
