I-Common Rail Fuel Injector Control valve Assembly F00VC01386 ye-Injector 0445110387 & 0445110388

Uhlalutyo lwamazwe adlulayo kwii-injini ze-CI kunye nokusetyenziswa kweendlela zokukhanya(ICANDELO 7)

Kuzo zombini ii-injection, ukulibaziseka kwempendulo ye-hardware kuthathwa njengesiqhelo kwaye yi-0.012 ms ye-piezo- kunye ne-0.016 ye-solenoid injector.Njengoko umqondiso wokukhanya we-diode usenzeka kwisakhelo esinye emva kokuqala komlinganiselo ngamnye, kunokuchazwa ukuba imilinganiselo izinzile kwaye iyaphinda.Umzobo 5 ubonisa ixesha elifutshane elinika amandla kuzo zombini iindidi zee-injection, njengoko sele kukhankanyiwe kwindlela yophando.Eli xesha lifikelela kwi-0.2 ms kunye ne-0.3 ms ye-piezo- kunye ne-solenoid injector, ngokulandelanayo.

Kwitshathi ye-piezo-injector, umkhwa wokukhawulezisa inaliti ngoxinzelelo oluphezulu kwigumbi laboniswa.Kuphela kwi-Pinj = 60 MPa olu tyekelo lwahlukile, kodwa lunokuphenjelelwa ziimeko ezingalindelekanga.I-solenoid injector yayisebenza ngendlela ephindaphindiweyo kwaye i-back-pressure ayizange yenze nayiphi na umehluko omkhulu kwixesha lokulibaziseka.Kuloo meko uxinzelelo lwenaliti yayiyeyona nto yayikhawulezisa inaliti, njengoko yayisele ijongwe kwi-piezo-injector.Eyona nto ibalulekileyo ukuyikhankanya yinyani, yokuba iziphumo zesitofu se-solenoid ukusuka kwi-Pinj ngaphezulu kwe-MPa ye-60 kwiimeko ezininzi zohluka nge-±1 isakhelo kuphela, ngoko ke ngokomlinganiselo wokuchaneka kufuneka ziphathwe njengokungekho mahluko.I-Piezo-injector kuxinzelelo lwenaliti ephantsi ifumene ukulibaziseka okuphantsi kune-electro-injector, kodwa ngokunyuka koxinzelelo oluye lwatshintshwa.Kufuneka kuqatshelwe ukuba i-piezo-injector luyilo oludala: i-electromagnetic injector ithathe indawo ye-piezo-injector kuyilo lomenzi.

Iziphumo zokulibaziseka kwesitofu kwixesha eliphakathi kunye nexesha elide lokutofa libonakaliswe kumfanekiso wesi-6 kunye nomfanekiso wesi-7, ngokulandelanayo.Umsebenzi we-piezo-injector unokuvavanywa njengento engaqhelekanga.Ngokwesiseko sothelekiso lweziphumo kunokuchazwa, ukuba uxinzelelo lomoya (uxinzelelo lwangasemva) lunempembelelo enkulu ekulibazisekeni kwaye ifuthe loxinzelelo lwamafutha lincinci.Iziphumo ezifanayo kakhulu ziye zafikelelwa kwizitofu ze-solenoid, kodwa kule meko eyona mpembelelo inkulu ekulibazisekeni kokutofa yayinoxinzelelo lwepetroli kunye nefuthe loxinzelelo lomoya lingenamsebenzi.
