▁system ▁and ▁so ▁the ▁engine . ▁If ▁an ▁out - of - spec ification ▁fuel ▁is ▁introduced ▁to ▁a ▁system ▁that ▁has ▁specific ▁parameters ▁of ▁operation , ▁then ▁the ▁integrity ▁of ▁the ▁overall ▁fuel ▁system ▁may ▁be ▁comprom ised . ▁Some ▁of ▁these ▁parameters ▁such ▁as ▁sp ray ▁pattern ▁and ▁atom ization ▁are ▁directly ▁related ▁to ▁injection ▁timing . ▁ ▁One ▁study ▁found ▁that ▁during ▁atom ization , ▁b iod ies el ▁and ▁its ▁bl ends ▁produced ▁dro ple ts ▁greater ▁in ▁diameter ▁than ▁the ▁dro ple ts ▁produced ▁by ▁traditional ▁pet rod ies el . ▁The ▁smaller ▁dro ple ts ▁were ▁attributed ▁to ▁the ▁lower ▁vis cos ity ▁and ▁surface ▁t ension ▁of ▁traditional ▁dies el ▁fuel . ▁It ▁was ▁found ▁that ▁dro ple ts ▁at ▁the ▁peri ph ery ▁of ▁the ▁sp ray ▁pattern ▁were ▁larger ▁in ▁diameter ▁than ▁the ▁dro ple ts ▁at ▁the ▁center . ▁This ▁was ▁attributed ▁to ▁the ▁faster ▁pressure ▁drop ▁at ▁the ▁edge ▁of ▁the ▁sp ray ▁pattern ; ▁there ▁was ▁a ▁proportional ▁relationship ▁between ▁the ▁dro ple t ▁size ▁and ▁the ▁distance ▁from ▁the ▁inject or ▁tip . ▁It ▁was ▁found ▁that ▁B 1 0 0 ▁had ▁the ▁greatest ▁sp ray ▁pen etr ation , ▁this ▁was ▁attributed ▁to ▁the ▁greater ▁density ▁of ▁B 1 0 0 . ▁Having ▁a ▁greater ▁dro ple t ▁size ▁can ▁lead ▁to ▁in e ffic ien cies ▁in ▁the ▁comb ust ion , ▁increased ▁em issions , ▁and ▁decre ased ▁horse ▁power . ▁In ▁another ▁study ▁it ▁was ▁found
