Abstract

Fuel injector nozzle is important part of fuel injection system which plays dominant role in spray formation which directly and indirectly affects on combustion efficiency of diesel engine. The performance of the internal flow of the fuel injector nozzle is impeded by several factors. Cavitation is one of the factor which affects fluid flow. It is associated with local pressure distribution inside nozzle. Therefore cavitation plays major role while designing injector nozzle.

In the present study, analysis of existing six hole mini-sac diesel injector nozzle is carried out using commercial CFD package. The main objective of research is to design of nozzle to avoid cavitation and to find out contribution of different parameters through parametric study. The results are predicted and compared with both test result and analytical result at steady state conditions for different needle lift., the better the results.
