Isitofu esiNtsha esiQhelekileyo sikaLoliwe se-F00RJ01683 iNdibano yoLawulo lweValve ye-Injector 0445120080 0445120268

Uhlalutyo lwamanani kunye nezifundo zovavanyo kwi-solenoid eqhelekileyo kaloliwe i-diesel injector enevalve yokulawula egugileyo(Icandelo1)

Abstract.

imodeli yemathematika yesitofu se-solenoid esiqhelekileyo sikaloliwe yaphuhliswa.Umahluko wayo kwiimodeli ezikhoyo kukulinganisa ukunxitywa kwevalve yokulawula.I-injector kaloliwe eqhelekileyo ye-0445110376 Series (i-Cummins ISf 2.8 injini ye-Diesel) eveliswe yiNkampani ye-Bosch isetyenziswe njengento yophando.Iiparamitha ze-injector (ukuhanjiswa kwamafutha kunye nokuvuza ngasemva) zichongwe ngokubala kunye neendlela zokulinga.Imodeli ye-GT-Suite eyi-avareji eyi-R2 yi-0.93 nto leyo ethetha ukuba iqikelela imilo yezinga lokutofa ngokuchanekileyo kakhulu (iimeko zobugcisa ezisezantsi nezisezantsi zesitofu).Uhlalutyo lwamanani kunye nezifundo zovavanyo zibonise ukuba ukunxitywa kwevalve yokulawula kwandisa ukuvuza ngasemva kunye nokuhanjiswa kwepetroli (ingakumbi kwi-160 MPa).Imifuziselo yokubuyisela umva ukumisela ukuhanjiswa kwamafutha kunye neziphumo zokuvuza ngasemva kuxinzelelo lwamafutha kunye nexesha lokunika amandla zaphuhliswa (kwimeko yesiqhelo kunye neyobugcisa obuncinci).

1. Intshayelelo

Uninzi lwezithuthi zala maxesha ezineenjini zedizili zixhotyiswe ngeenkqubo zesitofu esiqhelekileyo sikaloliwe.Banceda ukuhlangabezana neemfuno ezingqongqo zokukhutshwa kwerhasi.Oku kunokwenzeka ngenxa yokuvelisa uxinzelelo lwamafutha aphezulu (de kube yi-300 MPa) kunye nokusetyenziswa kwe-biodiesel fuel [1-4].Izitofu zamafutha kaloliwe eziqhelekileyo zezona nxalenye zibalulekileyo zesixokelelwano [5].Bavumela ukuhanjiswa kwepetroli kwiisilinda ngokuchaneka okuphezulu kuxhomekeke kwindlela yokusebenza kwenjini.Kukho iindidi ezimbini zee-injection - ezine-actuator ze-piezo kunye ne-solenoid actuators [6-8].Nganye kuzo ineengenelo ezithile kunye nezingeloncedo [9].Nokuba loluphi na uhlobo lwesitofu esisetyenzisiweyo, ukuchaneka okuphezulu kokuhanjiswa kwamafutha kufuneka kubonelelwe ixesha elide.Iimeko zobugcisa zesixokelelwano sesibaso sikaloliwe esiqhelekileyo sitshintsha ngokunyuka kweemayile zemoto [10].
