The results show that as the injection pressure increased, the penetration depth is also increased as well as the spray angle. The conclusion has shown that the nozzle tip diameter is also effecting the overall spray structure because wider nozzle tip diameter will released more fuel quantity compared to the smaller nozzle tip diameter. 2013-06 Undergraduates Project Papers NonPeerReviewed pdf en http://umpir.ump.edu.my/id/eprint/8677/1/15.Computational%20study%20of%20fuel%20spray%20structure.pdf Mohd Hilmi, Mohd Zin (2013) Computational study of fuel spray structure.
