Diagnostics of common rail diesel injectors

Injini dzedhiziri dzemazuva ano dzine simba, dzine mari uye dzinogara. Asi, pasinei nezvakanaka zvavo zvose, vane pfungwa isina simba: iyo mafuta system. Madhiziri mazhinji anoshandisa Common Rail system. Ndezvipi? Majekiseni anoongororwa sei? Vanogadzirisika sei? Kupfuurirazve muchinyorwa, isu tichakurukura zvakanyanya kusashanda kweakajairika njanji dizeli majekiseni uye kuongororwa kwavo.

Mhando dzeCommon Rail systems

Kune akati wandei marudzi eCommon Rail masisitimu, asi musimboti anowira mumapoka maviri:

• electromagnetic,
• piezoelectric.

Masisitimu akadaro anowanikwa pasi pemazita mana emhando:

1. empty
2. Continental (yaimbova Siemens),
3. Delphi,
4. Dense.

Mutungamiriri wemusika ndiBosch, inomiririra ruzhinji rwemajekiseni edhiziri. Pasi pemhando iyi, ese emagetsi uye piezoelectric dhiziri nozzles anogadzirwa. Delphi inogadzirawo marudzi maviri emajekiseni. Uye Denso neContinental vanongogadzira piezoelectrics.

Hazvibviri kutaura kuti ndeupi mhando yeCommon Rail diesel injectors iri nani, sezvo masisitimu akasiyana ane zvawo zvakanakira nekuipira. Majekiseni eBosch ndiwo ari nyore kugadzirisa: kwete chete ane dhizaini yakareruka pane ese, iwowo ndiwo akajairika, saka kutsvaga kutsiva hakusi dambudziko.

Delphi majekiseni edhiziri akanyanya kuoma: vane hurongwa hwekutonga hwakaoma. Nekuda kweizvi, majekiseni akave akanyanya kutarisisa kunaka kwedhiziri, saka vanga vasingashande munyika yedu kwenguva yakareba. Paunenge uchigadzirisa majekiseni edhiziri emamwe mabhureki, kazhinji pane dambudziko nekutsvaga maspare parts.

Kuchengetedza kwejanji njanji dizeli majekiseni

Kana, semugumisiro wekuongororwa kweCommon Rail diesel injectors, kukanganisa kunoonekwa, mubvunzo unomuka kana kugadzirisa kunogoneka kana kutsiva kwakakwana kuchadiwa. Vazhinji vevaridzi vanofara veCommon Rail fuel system ine Bosch majekiseni. Nekuda kwekureruka kwavo dhizaini uye kushandiswa kwakapararira, iwo ari nyore kuchengetedza uye anokwanisika kuvaka patsva.

Chero dambudziko rinenge rakabatana nekusashanda kwemajekiseni, zvinodikanwa kugadzirisa hurongwa hwemafuta chete munzvimbo yakasarudzika, nekuti mutengo wezvimedu unoshamisa uye hapana chikonzero chekuisa panjodzi. Kuti uongorore majekiseni edhiziri, kugadzirisa uye kuchinjwa, tapota taura https://dizelbox.ru/remont-dizelnyh-forsunok.

Delphi solenoid-type dhiziri majekiseni anonziwo anogona kugadziriswa, asi anodhura kuvaka patsva kupfuura Bosch. Izvi imhaka yokuti pashure kutsiva muromo (uye izvi zvinokosha), unofanira encode, kana zvikasadaro injini kushanda zvisina kugadzikana.

Denso electromagnetic dhiziri majekiseni haagadzirike. Chokutanga pane zvose, nozzles yemhando iyi ndiyo inonyanya kuvimbika uye yakasimba. Chechipiri, zvakanyanya kuoma kuwana zvakasara kwavari - muhuwandu hwakawanda hwezviitiko, zvinokurumidza, zviri nyore, uye dzimwe nguva zvakachipa kuisa zvitsva.

Bosch neDelf piezoelectric majekiseni haagone kugadziriswa. Kana panguva yekuongororwa kweCommon Rail diesel jekiseni kusashanda kwavo kwakaratidzwa, ipapo zvikamu zvinogara zvichishandurwa kuita zvitsva.

Kana ari Continental (yaimbova Siemens) majekiseni edhiziri, haana kugadzirwa kusvika nguva pfupi yadarika. Watove kutengeswa unogona kuwana matipi ejekiseni ekutsiva, uye emadhayamita akasiyana. Nokudaro, iwe unogona kusarudza sarudzo yakarurama kune chero jekiseni uye kudzorera kushanda kwayo nemutengo wakaderera (uchienzaniswa nekutenga imwe itsva.

Nguva Yekuziva Yakajairwa Rail Diesel Majekiseni

Maererano nemugadziri, hupenyu hwebasa reCommon Rail diesel jekiseni ndeye 100-150 zviuru zvemakiromita. Mukuita, mazhinji nozzles anogona kumira kusvika 150-200 zviuru zvemakiromita. Tichifunga nezve mutengo wezvikamu uye vashandi pakutsiva, matekinoroji haakurudzire kushandura dhiziri Common Rail jekiseni kudzamara matambudziko anobatika atanga nawo.

Izvo zvinodikanwa kuongorora Common Rail dizeli majekiseni kana kupera kwanyanya kupfungaira, kushandiswa kwemafuta kwakawedzera. Aya masaini maviri ndiwo zvikonzero zvikuru zvekubata iyo Common Rail Diesel Injector Diagnostic Assistant.

Zvikonzero zvekusashanda kwemajekiseni edhiziri enjanji

Ngatitarisei zvakadzama zvikonzero zvikuru zvekuputsika muhuturu system yeinjini dzedhiziri:

• Kuvhara.

Kana jekiseni rakavharika rinowanikwa panguva yekuongororwa kwedhiziri yakajairika majekiseni enjanji, muridzi anogona kufema, nekuti kusashanda uku kuri nyore uye hakudhure kugadzirisa.

Zvekuita: Geza tsono yakavharika. Izvi zvinogona kuitwa ne ultrasonic cleaner kana neruoko uchishandisa ma scrapers uye mabhurashi.

• Washing machine kupfeka

Pakati peatomizer uye chitubu muCommon Rail dhiziri jekiseni pane washer, iyo inopedzisira yakanganisa uye inorasikirwa nekusimba kwayo.

Zvekuita: Shandura muchina wekuwachisa.

• Kuora kwakanyanya kana kusakara.

Corrosion kana zviratidzo zvekupfeka kwakakosha, zvakaonekwa panguva yekuongororwa kwedhiziri zvakajairika majekiseni enjanji, zvinogona kutungamira kukuvadza kumuviri. Sezvo imba yacho isingagone kutsiviwa zvakasiyana, chikamu chitsva chinoda kupihwa.

Zvekuita: Isa jekiseni idzva redhiziri.

• Injector marongero akadzimwa.

Kushanda kwakarurama kwejekiseni redhiziri kunotarirwa nemiganhu yakawanda: kuvhura kumanikidzwa, jekiseni dhayamita, kufamba kwetsono, etc. Nokuda kweizvi, majekiseni akabatanidzwa kune kuiswa kwakakosha kunofananidzira kushanda kwejini. Muchiitiko ichi, mafuta anoputirwa papepa, achiita nzvimbo yeimwe chimiro.
