Majekiseni einjini

Injector yemafuta (TF), kana jekiseni, inoreva ruzivo rwejekiseni remafuta. Iyo inodzora kuyerwa uye kupihwa kwemafuta uye mafuta ekuzora, ichiteverwa nekupfapfaidza kwavo mukamuri yekupisa uye kusanganisa nemhepo kuita musanganiswa mumwe chete.

TFs inoshanda semasangano makuru makuru ane chekuita nejekiseni system. Kutenda kwavari, mafuta anopfapfaidzwa muzvikamu zviduku uye anopinda mujini. Nozzles yemhando ipi neipi yeinjini inoshanda chinangwa chimwe chete, asi inosiyana mukugadzira uye musimboti wekushanda.

Mafuta emafuta

Mhando iyi yechigadzirwa inoratidzirwa nekugadzirwa kwega kwega kune imwe mhando yemagetsi emagetsi. Mune mamwe mazwi, hapana mhando yepasirese yechishandiso ichi, saka hazvigoneke kuvarongazve kubva kune peturu injini kuenda kune dhiziri. Sezvisizvo, tinogona kutaura semuenzaniso ma hydromechanical modhi kubva kuBOSCH, akaiswa pamakanika masisitimu anoshanda nekuenderera mberi jekiseni. Iwo anoshandiswa zvakanyanya kune akasiyana emagetsi mayuniti sechinhu chakakosha cheiyo K-Jetronic system, kunyangwe iwo ane akasiyana magadzirirwo asina hukama kune mumwe nemumwe.

Nzvimbo uye musimboti wekushanda

Schematically, jekiseni ivharuvhu solenoid inodzorwa nesoftware. Iyo inovimbisa kupihwa kwemafuta kumasilinda mune akafanotemerwa madosi, uye yakaiswa jekiseni system inosarudza rudzi rwezvigadzirwa zvinoshandiswa.

Semuromo

Mafuta anopiwa kumuromo pasi pekumanikidzwa. Muchiitiko ichi, injini yekudzora unit inotumira magetsi kune injector solenoid, iyo inotanga kushanda kwevhavha yetsono inotarisira mamiriro echiteshi (yakazaruka / yakavharwa). Kuwanda kwemafuta anouya kunotarirwa nehuwandu hwemhepo inopinda, iyo inobata nguva iyo valve yetsono yakazaruka.

Nzvimbo yenozzles inoenderana neiyo chaiyo mhando yejekiseni system:

• Pakati: iri pamberi pevhavha ye throttle mune yakawanda yekutora.

• Kuparadzirwa: macylinders ose anoenderana neinozzle yakaparadzana iri pasi pepombi yekupinza uye jekiseni mafuta uye mafuta.

• Yakananga - nozzles inowanikwa pamusoro pemadziro evhavha, ichipa jekiseni zvakananga mukamuri rinopisa.

Majekiseni einjini dzepeturu

Injini dzepeturu dzakashongedzerwa nemhando dzinotevera dzemajekiseni:

• Single point - mafuta ekufambisa ari pamberi pe throttle.

• Multi-point: mapfumo akawanda ari pamberi pemapfumbu ane basa rekupa mafuta nemafuta kumasilinda.

TFs inopa kupihwa kwepeturu kukamuri yekupisa yesimba remagetsi, nepo dhizaini yezvikamu zvakadaro isinga patsanurwe uye haina kupa kugadzirisa. Pamutengo iwo akachipa pane iwo akaiswa pamainjini edhiziri.

majekiseni ane tsvina

Sechikamu chinovimbisa kushanda kwakajairwa kwemafuta system yemota, majekiseni anowanzo kutadza nekuda kwekusvibiswa kwezvinhu zvesefa zviri mazviri zvine zvinopisa zvigadzirwa. Madhipoziti akadaro anovhara nzira dzekupfapfaidza, izvo zvinokanganisa kushanda kwechinhu chakakosha - iyo valve yetsono uye inokanganisa kupihwa kwemafuta kukamuri yekupisa.

Majekiseni einjini dzedhiziri

Kushanda kwakaringana kwehuni system yeinjini yedhiziri inovimbiswa nemhando mbiri dzemazino akaiswa paari:

• Electromagnetic, nokuda kwekugadzirisa kukwira nekudonha kwetsono iyo inokonzera valve inokosha.

• Piezoelectric, hydraulically actuated.

Kurongeka kwakakodzera kwemajekiseni, pamwe nechiyero chekupfeka kwavo, kunokanganisa kushanda kwejini injini, simba rinobudisa uye huwandu hwemafuta anopedzwa.

Muridzi wemotokari anogona kuona kutadza kana kusashanda kwejekiseni redhiziri nenhamba yezviratidzo:

• Kuwedzera kushandiswa kwemafuta nekudhonza kwakajairika.

• Mota haidi kufamba uye inoputa.

• Injini yemotokari inodedera.

Matambudziko uye kusashanda kweinjini majekiseni

Kuti uchengetedze kushanda kwakajairika kweiyo mafuta system, zvinodikanwa kuti nguva nenguva uchenese ma nozzles. Maererano nenyanzvi, nzira yacho inofanira kuitwa makiromita 20-30 zviuru, asi mukuita kudiwa kwebasa rakadaro kunomuka mushure memakiromita 10-15 zviuru. Izvi zvinokonzerwa nekushata kwemafuta emhando, mamiriro asina kunaka emumigwagwa uye kwete nguva dzose kutarisirwa kwakakodzera kwemotokari.

Matambudziko akanyanya kudzvanya nemajekiseni emhando ipi neipi anosanganisira kutaridzika kwemadhipoziti pamadziro ezvikamu, izvo zvinoguma nekushandisa yakaderera-mhando mafuta. Mhedzisiro yeizvi ndiko kutaridzika kwekusvibiswa mune inopfuta yemvura yekugovera sisitimu uye kuitika kwekukanganisa mukushanda, kurasikirwa kweinjini simba, kunyanyisa kushandiswa kwemafuta uye mafuta ekuzora.

Zvikonzero zvinokanganisa kushanda kwemajekiseni zvinogona kuva:

• Sarufa yakawandisa mumafuta uye mafuta ekuzora.

• Kuora kwezvinhu zvesimbi.

• Inounza.

• Masefa akavharwa.

• Kuiswa kusina kururama.

• Kusangana nekupisa kwakanyanya.

• Kupinda kwehunyoro nemvura.

Njodzi iri kuuya inogona kuzivikanwa nezviratidzo zvakawanda:

• Kuitika kwekukundikana kusina kurongwa paunotanga injini.

• Kuwedzera kunokosha kwemafuta ekushandisa zvichienzaniswa nehuwandu hwezita.

• Kuonekwa kwekutsvaira kwakasviba.

• Kuonekwa kwekukundikana kunotyora rhythm yeinjini pasina basa.

Nzira dzekuchenesa majekiseni

Kuti ugadzirise matambudziko ari pamusoro apa, nguva nenguva kutsvaira kwemajekiseni emafuta kunodiwa. Kuti ubvise zvakasvibiswa, kuchenesa kwe ultrasonic kunoshandiswa, mvura inokosha inoshandiswa, kuita maitiro emaoko, kana zvimwe zvinowedzera zvinowedzerwa kuchenesa majekiseni pasina kuparadzanisa injini.

Zadza duru mutangi regesi

Iyo iri nyore uye yakapfava nzira yekuchenesa yakasviba nozzles. Nheyo yekushanda kweiyo yakawedzera kuumbwa ndeyekugara ichinyungudutsa madhipoziti aripo mujekiseni system nerubatsiro rwayo, uye zvakare kudzivirira zvishoma kuitika kwavo mune ramangwana.

geza muromo nezvinowedzerwa

Iyi nzira yakanaka kune itsva kana yakaderera mileage mota. Muchiitiko ichi, kuwedzera flush kune tangi yemafuta kunoshanda senzira yekudzivirira kuchengetedza magetsi emuchina uye system yemafuta yakachena. Kune motokari dzine mafuta akasvibiswa zvakanyanya, iyi nzira haina kukodzera, uye mune dzimwe nguva inogona kukuvadza uye kuwedzera matambudziko aripo. Nehuwandu hwakawanda hwekusvibiswa, iyo yakashambidzwa madhipoziti inopinda mumhino, ichivhara iwo zvakanyanya.

Kuchenesa pasina kuputsa injini

Kutsvaira kweTF pasina kuparadzanisa injini kunoitwa nekubatanidza iyo yekutsvaira unit yakananga kune injini. Iyi nzira inokubvumira kuti ugeze tsvina yakaunganidzwa pamagetsi uye njanji yemafuta. Injini inotanga isingaiti kwehafu yeawa, musanganiswa unopiwa pasi pekumanikidzwa.

kugezesa nozzles nemudziyo

Iyi nzira haina kukodzera kune injini dzakasakara uye haina kukodzera kumotokari dzine KE-Jetronik yakaiswa.

Kuchenesa ne disassembly ye nozzles

Muchiitiko chekusvibiswa kwakanyanya, injini inoparadzaniswa pachigadziko chakakosha, mitsipa inobviswa uye inocheneswa zvakasiyana. Manipulations akadaro anokubvumirawo kuti uone kuvapo kwekusashanda mukushanda kweinjection pamwe nekutsiviwa kwavo kwakatevera.

kubvisa uye kuwacha

ultrasonic kuchenesa

Manozzles anocheneswa mune yekugezesa ye ultrasonic yezvikamu zvakambobviswa. Iyo sarudzo yakakodzera tsvina inorema isingagoni kubviswa nemuchenesi.

Mashandiro ekuchenesa nozzles pasina kuabvisa kubva mujini anodhura muridzi wemota avhareji ye15-20 US madhora. Mutengo wekuongorora nekuzocheneswa kwejekitori pa ultrasound scan kana pastand ingangoita 4-6 USD. Basa rakazara pakutsvaira uye kutsiva zvikamu zvega rinokutendera kuti uve nechokwadi chekushanda kusingapindiki kweiyo mafuta system kweimwe mwedzi mitanhatu, uchiwedzera 10-15 zviuru zvemakiromita kune mileage.
