Muhurukuro yanhasi, tichabata mashandiro uye kushanda kweDiesel Particulate Filter (DPF).Misoro yakafukidzwa inosanganisira:
-DPF yemukati chimiro, kushanda uye kushandiswa
- DPF Regeneration neOscilloscope kuverenga
- Zvinokonzera DPF Kukundikana
Mhoro, Nhasi ndichakutora kuburikidza nekuvaka uye basa redhiziri particulate sefa.Mazuva ehutsi hutema hwakasviba ari kukurumidza kupera nekuda kwehunyanzvi hwekupedza dhiziri huri kushanduka nekufamba kwemakore, uye mitemo yakasimba yekuburitsa yaida injini dzedhiziri kuti dzive dzakachena zvakanyanya.
Iyo dhiziri particulate sefa inozivikanwawo seDPF,chishandiso chesefa chakasungirirwa kupedza masisitimu painjini dzemazuva ano dzedhiziri. These zvishandiso zvinogona kuiswa pamberi kana mushure meiyo catalytic converter.
Zvinoda kupisa kuti zvishande nemazvo. Tndosaka mamwe mafirita edhiziri akaiswa zvakananga mushure meiyo turbocharger.
Dhizaini yeDPF ine muzinga weuchi sefa monolith uye yakavharirwa mugoko resimbi senge catalytic converter yakabatana.
Iyo inosiyanisa kudzvanywa sensor ine mapaipi anouya akaiswa yekupinza uye kubuda kweDPF ichavhara izvi munguva pfupi.. Aya ndiwo mafirita zvinhu zvinouya mune zvakawanda zvakasiyana.
Aya ndiwo mafirita mafirita anouya mune akawanda akasiyana zvinhu zvinonyanya kushandiswa neDPF cordierite wall flow mafirita kana silicon carbide wall flow sefa..Zvimwe zvinhu zvinogona kusanganisira simbi faibha mafirita, simbi faibha inoyerera kuburikidza nemafirita uye chidimbu mafirita.Common-rail injini dzedhiziri dzakaiswa neDPF dzinoda mafuta akaderera akaderera.
Chinangwa cheDPF ndechekuteya zvimedu zvakagadzirwa neinjini dzese dzedhiziri,kudzidzivisa kupinda mumhepo. Izvi zvinokuvadza zvakanyanya kumhepo yekufema. Iwo ma particulate akavharirwa ne microscopic channels ari mukati me dhiziriparticulate sefa.Tane particulate kana soot inonamira kumadziro enzira mukati meDPF inopiswa nguva nenguva ichinzi regeneration..
Iko kuvandudzwa kunodzivirira dizeli particulate sefa kubva pakuvharira kumusoro. Kune marudzi matatu ekuzvarwa patsva zvinongoerekana zvaitika, zvine simba uye sevhisi.Kuchinja kunongoerekana kwaitika uye sevhisi yekuzvarwa patsva inoitika kana DPF yasvika 600 madhigirii Celsius e1112 madhigirii Fahrenheit kana kuzvarwa patsva kukasaitika.,uye ECU inoverenga kuti DPF yasvika pakuchengeta kwayo.
A dynamic regeneration inotangwa dynamic regeneration inoratidzwa kana DPF mwenje ichivhenekera pane chiridzwa cluster.. Motokari inofanira kuramba ichienda kunopedzisa kuvandudzwa kusvikira chiedza chadzima. Kana iyo dynamic regeneration ikakanganiswa neinjini ichimiswa,it yaizotangwa patsva pane inotevera injini kumhanya kutenderera kana iyo ine simba yekuvandudza ichiramba ichivhiringwa nekuda kwenhambo pfupi dzenzendo.. Chiedza cheDPF chichatanga kupenya.
Yambiro yekutsvaira yeDPF inoratidza kuti basa rekuvandudza rinofanira kuitwa.Re-generations inofanirwa kukurudzirwa uchishandisa chishandiso chekuongorora panguva yekuvandudza sevhisi. Extra mafuta anogona kuwedzerwa mune mamwe mafuta anogona kuwedzerwa pamberi pepost jekiseni pulses. Izvi zvinowedzera tembiricha yekubuda kwegasi kugadzira kupisa kwakanyanya pf kunosvika 600 degrees Celsius ye1112 degrees Fahrenheit.. Saka isu zvino nema particulates ekupisa kana yambiro inopenya yeDPF ikasateererwa.
Kuunganidzwa kwesoti kunogona kusvika pamwero wekuti kutsiva DPF ndiyo yega mushonga unogoneka. Kamwe kana basa rekuvandudzwa kwaitwa kuverenga kubva kusiyanisa kudzvinyirira sensor kunozoona kuti kushanda patsva kwave kwakadii.
Uzvirokwazvo kuvandudzwa kune simba kunoda kuteverarudzi rwekuvandudzwa kwesevhisi kuita kutenderera kwakakodzera kwekutyaira. Kana kuberekwa patsva kusingabviri,iyo diesel particulate sefa inofanira kutsiviwa.
Magasi ekupera simba asina kucheneswa anosiya masilinda maviri akatakura machende kuenda kuDPF, anosangana nemadziro emagetsi emagetsi uye soot inobatwa..Sutu iyi inoramba iri muDPF kusvika hurongwa hwekuvandudza hwatangwa.
Iye zvino tichatarisa iyo DPF scan tool parameters, ndiri kutarisa data nekuti ndine mwenje weDPF unopenya uye kuunganidza soot kunopfuura zana muzana..Ini ndichaita sevhisi yekuvandudza uye isu tinotarisa iyo injector pateni tichishandisa oscilloscope pane ino scan sevhisi yekuvandudza sevhisi iri mune yakakosha mabasa menyu.. Kana izvo zvinodikanwa zvazadzikiswa chishandiso che scan chinotanga kugadzirwa patsva.
Iyo pateni inotanga neairi mutyairi uye majekiseni makuru kana revs yawedzera, jekiseni rimwe repoly rinonyangarika iyo post jekiseni patani inoonekwa.. Uku kuita kuti DPF isvike pa600 madhigirii Celsius kana 1112 madhigirii Fahrenheit, nguva yacho ichasiyana zvichienderana nekupisa kweDPF uye inogona kutonyangarika kana yangozvarwa patsva.syapera, iyo yakajairika pateni ichaonekwa uye chimiro chakapedzwa chichaonekwa pane scan tool.
Kutenderera uku kunoitika kakawanda, iwe uchityaira uchichengeta DPF kuti isavharika nezviratidzo zveDPF yakundikana inogona kunge iri mwenje yekunyevera pane dash uye kusaita zvakanaka injini..
ADPF inogona kutadza nekutsemuka kwedzimba panguva yako yekuzvarwa patsva, kana iyo yekuchengetedza yakawandisa kana mafuta uye inotonhorera inosvibisa., tanosefa achiita kuti ivhare.That ndiko kuvaka uye kushanda kwedhiziri particulate sefa.
Zvakakosha kuti unzwisise kuti DPF inoshanda sei kuti ikubatsire pakuongorora. Ndinovimba uchazviwana zvichibatsira.Tozoonana.
