Ib qho ntawm cov xwm txheej tseem ceeb rau kev ua haujlwm kom raug ntawm lub cav diesel yog qhov kev txhaj tshuaj zoo. Ua ke nrog ib tus kws kho tsheb uas muaj kev paub dhau los, peb piav qhia txog qhov tsawg kawg nkaus thiab tsis muaj kev ntseeg siab tshaj plaws.

Regeneration thiab kho ntawm diesel injectors. Qhov zoo tshaj plaws txhaj tshuaj tshuab

Lub cav muaj zog ntau dua qhov siab dua cov roj txhaj tshuaj. Hauv cov tshuab hluav taws xob, cov roj diesel raug txhaj rau hauv chav combustion ntawm qhov siab heev. Yog li, lub tshuab txhaj tshuaj, piv txwv li lub twj tso kua mis thiab cov twj tso kua mis, yog qhov tseem ceeb ntawm cov tshuab no.

Ntau yam kev txhaj tshuaj roj rau ntawm lub tshuab diesel

Cov tshuab txhaj tshuaj hauv cov tshuab diesel tau dhau los ua kev hloov kho thev naus laus zis hauv nees nkaum xyoo dhau los. Ua tsaug rau nws, cov abscesses nrov tsis tau pom tias yog kev cuam tshuam rau kev haus luam yeeb. Lawv tau dhau los ua kev lag luam thiab nrawm.

Niaj hnub no, kev txhaj tshuaj roj ncaj qha yog tus qauv ntawm cov tshuab diesel. Feem ntau cov kab ke yog Common Rail. Lub kaw lus tau tsim los ntawm Fiat thaum ntxov 90s, tab sis patent tau muag rau Bosch vim tias muaj nqi ntau lawm. Tab sis thawj lub tsheb nrog cov kab ke no yog xyoo 1997 Alfa Romeo 156 1.9 JTD.

Nyob rau hauv ib qho kev tsheb ciav hlau, roj yog sau rau hauv ib qho yeeb nkab thiab tom qab ntawd muab faib rau hauv qhov siab siab rau cov tshuaj txhaj tshuaj. Cov li qub nyob rau hauv lub injectors qhib nyob ntawm seb lub cav ceev. Qhov no ua kom muaj kev pom zoo ntawm cov khoom sib xyaw hauv lub tog raj kheej thiab txo cov roj noj. Tsuas yog ua ntej kev txhaj tshuaj roj tiag tiag, lub npe hu ua pre-injection rau pre-heat lub combustion chamber. Yog li ntawd, ignition sai dua ntawm cov roj thiab kev ua haujlwm ntsiag to ntawm lub zog hluav taws xob tau ua tiav.

Muaj ob hom Common Rail systems: nrog electromagnetic injectors (hu ua Common Rail 2003th tiam) thiab nrog piezoelectric injectors (hu ua thib XNUMX tiam). Cov yav tas yog cov niaj hnub, muaj tsawg dua qhov txav thiab sib dua. Lawv kuj muaj lub sijhawm ua haujlwm luv luv thiab tso cai rau kev ntsuas roj ntau dua. Txij li thaum XNUMX, feem ntau cov tuam txhab lag luam tau maj mam hloov mus rau lawv. Hom siv rau solenoid injectors suav nrog Fiat, Hyundai / KIA, Opel, Renault thiab Toyota. Piezoelectric injectors yog siv tshwj xeeb hauv cov tshuab tshiab. Mercedes, PSA txhawj xeeb (tus tswv ntawm Citroen thiab Peugeot), VW thiab BMW.

Lwm qhov kev daws teeb meem rau kev txhaj tshuaj roj ncaj qha hauv cov tshuab diesel yog chav injectors. Txawm li cas los xij, nws tsis siv rau hauv tsheb tshiab lawm. Lub twj tso kua mis injectors tau muab txoj hauv kev rau Common Rail system, uas ua haujlwm zoo dua thiab ntsiag to. Volkswagen, uas txhawb nqa cov tshuaj no, kuj tsis siv lawv.

Ob peb xyoos dhau los, Volkswagen thiab cov npe muaj feem xyuam (Audi, SEAT, Skoda) siv cov twj tso kua mis. Qhov no yog ib qhov system injector txhaj tshuaj (UIS). Cov khoom tseem ceeb yog mono-injectors nyob ncaj qha saum lub tog raj kheej. Lawv txoj haujlwm yog tsim kom muaj kev kub siab (tshaj 2000 bar) thiab txhaj tshuaj roj diesel.

Kev ntseeg tau ntawm kev txhaj tshuaj tshuab

Mechanics hais txog tias nrog rau kev txhim kho cov tshuab txhaj tshuaj, lawv qhov kev ntseeg tau txo qis.

- Qhov tsawg kawg nkaus thaum muaj xwm ceev diesel txhaj tshuab yog cov uas tau tso tawm ntau xyoo los yog ntau xyoo dhau los, nyob rau hauv uas lub ntsiab tseem ceeb yog lub siab-siab roj twj distributor - hais tias Marcin Geisler los ntawm Auto-Diesel-Service los ntawm Kobylnica ze Słupsk.

Piv txwv li, nrov Mercedes W123 chim muaj indirect txhaj. Muaj qee qhov txav mus los, thiab lub tshuab ua haujlwm txawm tias muaj roj tsawg. Qhov tsis zoo, txawm li cas los xij, yog kev nrawm nrawm, tsis muaj suab nrov ntawm lub cav ua haujlwm thiab kev siv roj av siab piv rau niaj hnub powertrains.

Cov qauv tsim tshiab - nrog kev txhaj tshuaj ncaj qha - tsis muaj qhov tsis txaus no, tab sis muaj kev nkag siab ntau dua rau cov roj zoo. Qhov no feem ntau yog vim li cas cov tshuab nrog electromagnetic injectors tsis tshua muaj kev ntseeg siab dua li cov tshuab nrog piezoelectric sawv daws yuav.

“Lawv tsuas yog tiv taus cov roj phem. Piezoelectrics poob sai sai thaum nyob rau hauv kev sib cuag nrog cov pa paug diesel. - piav qhia Geisler - Qhov zoo ntawm cov roj diesel yog ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm tag nrho cov kab ke. Cov roj paug uas tsis ua raws li cov qauv yog qhov ua rau muaj teeb meem.

Tseem muaj cov tshuab nrog electromagnetic nozzles uas tawg ntau dua li lwm tus. Qhov no yog qhov tseeb, piv txwv li, hauv Ford Mondeo III nrog 2.0 thiab 115 hp 130 TDCi cav. thiab Ford Focus I 1.8 TDCi. Ob lub tshuab siv Delphi hom tshuab.

- Qhov ua rau lub malfunction ntawm lub twj tso kua mis txhaj tshuaj. Tom qab disassembling nws, koj tuaj yeem pom cov ntaub ntawv hlau, uas, ntawm chav kawm, puas lub nozzles, tus kws kho tsheb piav qhia. - Nws yog ib qho nyuaj hais tias qhov no cuam tshuam rau qhov zoo ntawm cov roj los yog seb lub tshuab tsim cov twj tso kua mis puas lawm.

Cov teeb meem zoo sib xws yog raug rau Renault Megane II nrog lub cav 1.5 dCi. Lub twj tso kua mis Delphi tseem ua haujlwm ntawm no, thiab hauv cov roj hluav taws xob peb kuj pom cov ntaub ntawv hlau.

Notoriety kuj nrog Opel diesels, uas VP44 twj tso kua mis ua haujlwm. Cov cav no tsav, ntawm lwm tus, Opel Vectra III 2.0 DTI, Zafira I 2.0 DTI lossis Astra II 2.0 DTI. Raws li Gisler hais, ntawm kev khiav ntawm 200 txhiab km, lub twj tso kua mis seizes thiab yuav tsum tau rov tsim dua tshiab.

Ntawm qhov tod tes, HDi xyaw, tsim los ntawm Fabkis txoj kev txhawj xeeb PSA thiab siv hauv Citroen, Peugeot, thiab txij li xyoo 2007 hauv Ford tsheb, muaj teeb meem nrog kev nkag mus rau cov khoom qub qub, i.е. Siemens injectors.

"Lub nozzle puas tuaj yeem hloov tau nrog ib qho siv, tab sis kuv tsis pom zoo kom siv cov tshuaj no, txawm tias nws pheej yig dua," tus kws kho tsheb sau tseg.

Kho tus nqi

Tus nqi ntawm kev kho qhov kev txhaj tshuaj yog nyob ntawm hom injectors. Kev kho ntawm cov khoom siv hluav taws xob hluav taws xob no raug nqi txog PLN 500 txhua, suav nrog kev ua haujlwm, thiab muaj nyob rau hauv kev hloov ntawm tus kheej cov ntsiab lus ntawm cov tshuaj txhaj tshuaj.

- Qhov no yog tus nqi thaum siv cov khoom qub qub. Nyob rau hauv cov ntaub ntawv ntawm precision pab kiag li lawm xws li ib tug injector, nws yog zoo dua tsis siv hloov, hais Marcin Geisler.

Yog li ntawd, nyob rau hauv cov ntaub ntawv ntawm Denso systems siv nyob rau hauv Toyota engine, nws yog tsim nyog los hloov tag nrho cov injector, vim hais tias tsis muaj cov khoom qub nyob rau hauv lub khw.

Piezoelectric nozzles tsuas yog hloov tau tag nrho. Tus nqi yog PLN 1500 ib thooj, suav nrog kev ua haujlwm.

- Piezoelectric injectors yog cov khoom tshiab thiab lawv cov tuam txhab tseem tiv thaiv lawv cov patents. Tab sis qhov no yog cov ntaub ntawv nrog electromagnetic nozzles yav dhau los, yog li tom qab qee lub sij hawm tus nqi kho piezoelectrics tej zaum yuav poob, peb qhov chaw ntseeg.
