Ukuxilonga kwezitimela ezijwayelekile zikadizili

Izinjini zesimanje zikadizili zinamandla, ziyonga futhi zihlala isikhathi eside. Kodwa, naphezu kwazo zonke izinzuzo zabo, banephuzu elibuthakathaka: uhlelo lwe-fuel. Iningi likadizili lisebenzisa iCommon Rail system. Bayini? Atholwa kanjani ama-injection? Zilungiseka kangakanani? Ngokuqhubekayo esihlokweni, sizoxoxa ngokungasebenzi okuyinhloko kwama-injection ka-diesel wesitimela kanye nokuxilongwa kwawo.

Izinhlobo zezinhlelo ze-Common Rail

Kunezinhlobo eziningana zezinhlelo ze-Common Rail, kodwa empeleni ziwela emaqenjini amabili:

• i-electromagnetic,
• i-piezoelectric.

Amasistimu anjalo atholakala ngaphansi kwamagama ebhrendi amane:

1. ayinalutho
2. I-Continental (phambilini eyayaziwa nge-Siemens),
3. Delphi,
4. Kuminyene.

Umholi wemakethe ngu-Bosch, omele iningi lama-injection kadizili. Ngaphansi kwalolu phawu, kokubili ama-nozzles we-electromagnetic kanye ne-piezoelectric diesel akhiqizwa. I-Delphi iphinde ikhiqize zombili izinhlobo zama-injection. Futhi iDenso ne-Continental benza ama-piezoelectrics kuphela.

Akunakwenzeka ukusho ukuthi yiluphi uhlobo lwe-Common Rail injectors diesel olungcono, njengoba amasistimu ahlukene anezinzuzo zawo kanye nokubi. Ama-injection e-Bosch yiwona alula kakhulu ukuwalungisa: awagcini nje ngokuklama okulula kunawo wonke, futhi avame kakhulu, ngakho ukuthola ukushintshwa akuyona inkinga.

Ama-injection e-Delphi diesel ayinkimbinkimbi kakhulu: anesistimu yokulawula eyinkimbinkimbi. Ngenxa yalokhu, ama-injection avele azwela kakhulu izinga likadizili, ngakho-ke kade engasebenzi ezweni lakithi. Lapho ulungisa ama-injection kadizili wezinye izinhlobo, kuvame ukuba nenkinga ngokuthola izingxenye ezisele.

Ukugcinwa kwezijojo zikadizili zikaloliwe ezivamile

Uma, ngenxa yokuxilongwa kwe-Common Rail diesel injectors, ukushiyeka kubonakala, umbuzo uphakama ukuthi ukulungiswa kungenzeka yini noma ukushintshwa okuphelele kuyodingeka. Iningi labanikazi abajabule beCommon Rail fuel system enamajoyi eBosch. Ngenxa yokuklama kwawo okulula nokusetshenziswa okusabalele, akulula ukuwanakekela futhi athengeka kakhulu ukuwakha kabusha.

Kungakhathaliseki ukuthi iyiphi inkinga ehlotshaniswa nokungasebenzi kahle kwama-injection, kuyadingeka ukulungisa uhlelo lukaphethiloli kuphela esikhungweni esikhethekile, ngoba izindleko zezingxenye ezisele ziyamangalisa futhi asikho isidingo sokuyibeka engozini. Ukuze uthole ukuhlonzwa kwezijovo zikadizili, ukulungiswa nokushintshwa kwazo, sicela uthinte i-https://dizelbox.ru/remont-dizelnyh-forsunok.

Izijovo zikadizili zohlobo lwe-Delphi solenoid nazo zithathwa njengezingalungiseka, kodwa zibiza kakhulu ukwakha kabusha kune-Bosch. Lokhu kungenxa yokuthi ngemva kokufaka ithiphu (futhi lokhu kuyadingeka), udinga ukufaka ikhodi, ngaphandle kwalokho injini izosebenza ngokungazinzile.

Ama-Denso electromagnetic diesel injection cishe awalungiseki. Okokuqala, ama-nozzles alo mkhiqizo athembekile kakhulu futhi ahlala isikhathi eside. Okwesibili, kunzima kakhulu ukuzitholela izingxenye ezisele - ezimweni eziningi, kuyashesha, kulula, futhi ngezinye izikhathi kushibhile ukufaka ezintsha.

Ama-injection e-Bosch kanye ne-Delf piezoelectric awakwazi ukulungiswa. Uma ngesikhathi sokuxilongwa kwe-Common Rail diesel injection ukungasebenzi kahle kwabo kwembulwa, khona-ke izingxenye zishintshwa njalo zibe ezintsha.

Ngokuqondene nama-injection kadizili e-Continental (yangaphambili i-Siemens), awakalungiswa kuze kube muva nje. Usuvele uthengiswa ungathola amathiphu omjovo wokushintshwa, kanye namadayamitha ahlukene. Ngakho-ke, ungakhetha inketho efanele yanoma yimuphi umjovo futhi ubuyisele ukusebenza kwayo ngezindleko ezincane (uma kuqhathaniswa nokuthenga entsha.

Isikhathi Sokuhlonza Izijovo Zedizili Ezivamile Zesitimela

Ngokusho komkhiqizi, impilo yesevisi ye-Common Rail diesel injectors ingamakhilomitha ayizinkulungwane eziyi-100-150. Eqinisweni, ama-nozzles amaningi angakwazi ukumelana namakhilomitha ayizinkulungwane ezingu-150-200. Uma kucatshangelwa izindleko zezingxenye nezabasebenzi lapho kushintsha, ochwepheshe abatusi ukushintsha izijovo zikadizili Ezivamile kuze kube yilapho kuqala izinkinga ezibambekayo ngazo.

Kuyadingeka ukuxilonga ama-injection kadizili e-Common Rail uma i-exhaust isishunqa kakhulu, ukusetshenziswa kukaphethiloli kwenyukile. Lezi zimpawu ezimbili ziyizizathu eziyinhloko zokuxhumana ne-Common Rail Diesel Injector Diagnostic Assistant.

Izimbangela zokungasebenzi kahle kwezijovo zikadizili zikaloliwe

Ake sicabangele ngokuningiliziwe izimbangela eziyinhloko zokuwohloka kwesistimu kaphethiloli yezinjini zikadizili:

• Ukuvimba.

Uma i-injector evimbekile itholakala ngesikhathi sokuxilonga ama-injection e-diesel common rail, umnikazi angakhipha umoya, ngoba lokhu kungasebenzi kulula futhi akubizi ukukulungisa.

Okufanele ukwenze: Sula inaliti yomlomo ovalekile. Lokhu kungenziwa nge-ultrasonic cleaner noma ngesandla usebenzisa ama-scrapers akhethekile namabhulashi.

• Ukugqokwa komshini wokuwasha

Phakathi kwe-atomizer kanye nesiphethu ku-Common Rail diesel injector kukhona iwasha, egcina ikhubaza futhi ilahlekelwe ukuqina kwayo.

Okufanele ukwenze: Shintsha umshini wokuwasha.

• Ukugqwala okukhulu noma ukuguga.

Ukugqwala noma izimpawu zokuguga okuphawulekayo, ezikhonjwe ngesikhathi kuxilongwa ama-injection ka-diesel common rail, kungaholela ekulimaleni komzimba. Njengoba indlu ayikwazi ukushintshwa ngokuhlukana, ingxenye entsha izodinga ukuhlinzekwa.

Okufanele ukwenze: Faka isijojo esisha sikadizili.

• Izilungiselelo zomjovo zivaliwe.

Ukusebenza okulungile kwe-injector ye-diesel kunqunywa imingcele eminingana: ingcindezi yokuvula, ububanzi be-injector, ukuhamba kwenaliti, njll. Kulokhu, uphethiloli ufuthwa ephepheni, okwenza indawo yokuma okuthile.
