In the present work, influence of nozzle holes diameter is studied on the first and second law balance in DI Diesel engine. To this aim, the first law analysis is done by using the results of a three dimensional CFD model. The results show a good agreement with the experimental data. Also for the second law analysis, a developed in house computational code is applied. Behaviors of the results have a good accordance with the literature. The results show that increase in nozzle holes diameter increases both indicated work and heat loss to walls. Also about the second law terms, results declare that increase in nozzle holes diameter leads to increase in indicated work availability, heat loss availability, and entropy generation per cycle and decrease in combustion irreversibility and exhaust gas availability.
