Yuav ua li cas ntxuav ib tug diesel particulate lim

Kev ua qias tuaj ntawm ntau yam tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub tsheb thiab nws cov khoom ntiag tug. Yuav ua li cas ntxuav cov lim dej hauv tsev.

Yuav ua li cas nws ua hauj lwm

Diesel cav tau dhau los ua neeg nyiam. Nyob rau hauv 2011, European emissions txoj cai nruj, yuav tsum tau manufacturers rau nruab ib tug particulate lim rau diesel tsheb. Nyob rau hauv cov xwm txheej zoo tag nrho, lub tshuab lim dej diesel yuav ntxuav tau yuav luag 100 cov pa pa tawm.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub lim yog qhov yooj yim heev: cov kua qaub uas tshwm sim los ntawm kev ua haujlwm ntawm lub cav ntim hauv cov catalyst thiab hlawv tawm. combustion tshwm sim nyob rau hauv lub regeneration hom, thaum cov roj txhaj tshuaj yog nce, raws li ib tug tshwm sim ntawm cov seem ntawm cov khoom yog hlawv.

Cov cim qhia txog kev kis kab mob

Cov lim dej muaj nws tus kheej qhov hluav taws xob. Soot nws tus kheej yog tsim los ntawm combustion ntawm diesel roj thiab huab cua, nws settles nyob rau hauv lub lim honeycombs. Tom qab ntawd, tom qab hlawv ntawm hydrocarbons tshwm sim, raws li qhov tshwm sim ntawm cov resins tsim. Tom qab ntawd lawv lo ua ke, uas ua rau txhaws ntawm lub lim. Cov laj thawj tseem ceeb rau kev tsis kam lees yog:

• siv cov roj uas muaj ntau yam teeb meem impurities lossis roj tsis zoo;
• siv cov roj cav uas tsis zoo;
• mechanical puas tsuaj, nrog rau cov tshuab hauv qab lub tsheb lossis kev sib tsoo;
• rov tsim dua tsis raug lossis qhov ua tsis tau ntawm nws qhov kev siv.

Cov hauv qab no yuav qhia tau tias muaj kev puas tsuaj hauv kev ua haujlwm ntawm cov lim dej lim:

• lub tsheb pib pib zuj zus, lossis tsis pib txhua;
• nce roj noj;
• qhov tsos ntawm ib qho tsis kaj siab tsw nyob rau hauv lub tsheb;
• cov xim ntawm cov pa luam yeeb los ntawm cov yeeb nkab tso pa hloov pauv;
• lub fault indicator lights.

Nco tseg! Cov kws tshaj lij qhia kom ua qhov kev kuaj mob tsawg kawg 2 zaug hauv ib xyoos.

Rau txhua hom tsheb, muaj cov software tshwj xeeb uas tau nruab rau ntawm lub laptop. Nrog kev pab ntawm qhov kev pab cuam, tus tswv lub tsheb tuaj yeem kuaj xyuas qhov xwm txheej ntawm lub cav thiab lub tsheb tag nrho. Thaum tsis muaj lub sijhawm zoo li no, qhov kev sim tuaj yeem ua tau ntawm txhua qhov chaw kuaj mob.

Cov lim dej tuaj yeem ua tiav tag nrho thiab cov tshuab ua kom tawg, lossis tsuas yog txhaws nrog cov khoom tawg. Nyob rau hauv thawj rooj plaub, lub lim yuav tsum tau hloov, thiab nyob rau hauv lwm yam nws yuav tsum tau ntxuav. Cov lim dej tuaj yeem ntxuav tau ob qho tib si los ntawm cov kws tshaj lij thiab nrog koj tus kheej tes.

Kev siv cov additives

Thaum txheeb xyuas seb yuav ua li cas ntxuav cov lim dej hauv tsev, nws yuav tsum tau muab sau tseg tias muaj kev tsim kho dua tshiab los tiv thaiv cov pa phem. Txhawm rau ua qhov no, lub cav yuav tsum tau ua kom sov siab tshaj 500 degrees, thiab cov hluav taws xob hluav taws xob yuav ua kom cov roj ntau ntxiv. Yog li ntawd, cov seem hauv cov lim yuav hlawv tawm.

Nyob rau hauv txoj kev niaj hnub no, kev ua tiav cov cua sov no yog qhov teeb meem heev. Yog li ntawd, koj tuaj yeem siv cov kev pabcuam ntawm cov chaw nres tsheb roj, qhov twg lub tsheb nrawm nrawm mus rau qhov zoo tshaj plaws.

Koj yuav tsum tau siv cov khoom siv tshwj xeeb uas ntxiv rau lub tank roj thiab ntxuav cov lim dej thaum tsav tsheb. Cov tshuaj ntxiv yuav tsum tau ntim txhua 2-3 txhiab km. Cov kws tshaj lij tsis qhia kom sib xyaw ntau hom tshuaj ntxiv.

Nco tseg! Kev ntxuav ntawm lub lim tuaj yeem ua tiav los ntawm disassembled los yog ntxuav nws ncaj qha rau hauv lub tsheb. Thawj txoj kev yuav ua rau kev tu kom tiav, tab sis nws siv zog ua haujlwm thiab siv sijhawm ntev.

Nrog dismantling

Disassembly tuaj yeem nyuaj los ntawm qhov tseeb tias cov mounting bolts yuav tsum tau ua tib zoo txiav tawm thiab tom qab ntawd hloov nrog cov tshiab. Tom qab disassembly, tshuaj xyuas qhov kev puas tsuaj rau cov khoom siv. Tom qab ntawd, muab cov kua tshwj xeeb ntxuav, nchuav rau hauv lub lim thiab cov cuab yeej siv tshuab tau txhaws. Koj tuaj yeem muab cov lim dej tso rau hauv lub thawv thiab tsuas yog nchuav cov kua.

Tom qab ntawd nyeem cov lus qhia. Raws li txoj cai, kev tu yuav siv sijhawm 8-10 teev. Tsuas yog cov kua roj av zoo yuav tsum tau siv. Qhov nruab nrab, 1 puv 5-liter hub yog xav tau. Tom qab ntawd, cov lim dej yog ntxuav thiab qhuav kom huv si. Thaum txhim kho, nws yog qhov zoo dua los npog cov pob qij txha nrog sealant. Tom qab kev teeb tsa tiav, pib lub cav thiab ua kom sov. Cov kua uas tseem tshuav yuav tawm los ua vapor.

Cov hau kev ntxiv

Kuj tseem muaj ob txoj hauv kev los ntxuav cov lim dej hauv tsev. Hauv paus lawv tsis txawv, tsuas yog ib qho sai me ntsis. Txhawm rau tiv thaiv hluav taws, siv cov alkaline-dej sib tov, nrog rau cov kua tshuaj ntxuav tshwj xeeb. Nws yuav siv li 1 liter ntawm cov kua ntxuav thiab li 0,5 liv ntawm xab npum.

Nws yog ib qho tsim nyog kom sov lub cav thiab hu rau lub overpass. Siv rab phom siab, ncuav cov kua ntxuav rau hauv lub qhov. Ua li no, unscrew lub ntsuas kub sensor los yog siab sensor. Tom qab ntawd, koj yuav tsum tau nruab cov sensors hauv lawv qhov chaw thiab tsav tsheb li 10 feeb. Thaum lub sij hawm no, cov av yuav yaj. Tom qab ntawd nws yog ib qho tsim nyog los tso cov kua ntxhua khaub ncaws thiab sau cov ntxhua khaub ncaws tib yam.

Tom qab ntawd nws yog ib qho tsim nyog yuav tsum tau unscrew lub ntsuas kub los yog lub siab sensor thiab siv rab phom txhaj los sau cov kua ntxuav. Nws yuav tsum tau ntxuav li 10 feeb, nrog rau cov tshuaj luv luv ntawm 10 vib nas this, sim nkag mus rau txhua qhov chaw nyuaj. Yuav tsum muaj qhov khoob ntawm kev txhaj tshuaj. Tom qab ntawd koj yuav tsum kaw lub qhov, rov ua cov txheej txheem tom qab 10 feeb. Tom qab ntawd, koj yuav tsum siv cov kua ntxhua khaub ncaws. Kev ntxuav yog dhau lawm, nws tseem tsuas yog pib lub tsheb thiab tos rau qhov kawg ntawm hom kev rov tsim dua tshiab.

Ua! Tus tswv lub tsheb yuav tsum nkag siab tias kev tu lub tshuab lim dej tsis yog ib qho panacea. Lub lim yog tsim los rau ib mais ntawm 150-200 txhiab km nrog kev ua haujlwm kom raug.

Yuav kom lub cav particle nyob ntev, koj yuav tsum ua raws li cov cai yooj yim:

• tsuas yog siv cov roj diesel zoo thiab cov roj cav;
• siv cov tshuaj tua kab mob uas tsim nyog;
• tos rau qhov kawg ntawm kev tsim dua tshiab thiab tsis txhob tua lub cav ua ntej;
• zam kev sib tsoo thiab kev sib tsoo.
• raug kuaj tsawg kawg 2 zaug hauv ib xyoos.

Tom qab ntxuav cov lim dej, lub tsheb yuav muaj roj tsawg dua, lub cav yuav ua haujlwm ntau dua, thiab cov pa hluav taws xob yuav txo qis. Kev saib xyuas kom zoo ntawm koj cov lim dej diesel yuav txuas ntxiv lub neej ntawm koj lub tsheb thiab tseem tiv thaiv ib puag ncig los ntawm cov pa phem.
