Izihluzi Diesel kwamaqondo eparticulate. Ukuqeshwa yesixhobo, isimiso ukusebenza

Ukuqaliswa kwemigangatho ezintsha kokusingqongileyo iimoto enyanzela abavelisi ukuphuhlisa iiteknoloji phambili ngakumbi ukuba ukuba iimveliso zabo ebezingahambelani nemigangatho. abazifunayo ezinjalo ngenxa ukuvela iintsapho iinjini ebonisa iimveliso processing ephantsi-ifezekiswe. Umsebenzi Luyaqhuba kwezinye iindawo. Ngoko ke, ngo-2004 kwakukho idiesel kwamaqondo eparticulate lokucoca ethi inciphise ezikhutshwayo eziyingozi. Nangona ngexesha ekuqaleni kwalo bekungenjalo kakhulu kwimfuno, abaphuhlisi ziye zaqhubeka ukuphuhlisa ingcinga, kunye namhlanje, ngokutsho i "Euro 5" umgangatho, ukufumaneka ifowuni kuyilo imoto kukho unxibelelwano.

Kutheni imfuneko lokucoca kwamaqondo eparticulate?

Devices yale hlobo ziyintoni kuthetha aftertreatment zegesi zeemoto. Ngoko nangoko kufanele kuqatshelwe ukuba filters kwamaqondo eparticulate esetyenziswa kwinjini diesel kuphela. Iiyunithi ipetroli of analogu kuvala. Eyona njongo iphambili yale ufakelo ukususa izinto eziyityhefu ukusuka zeemoto. Ezo iigesi yokwenza kwaye yenza nokusingqongileyo emotweni ngakumbi friendly. Amacebo inokuba nomahluko kwisixhobo, kodwa enze umsebenzi yokunciphisa umxholo umlotha wokupasa zeemoto nge-80%.

Ngelishwa, ukwenziwa kwalo msebenzi ibandakanya kakhulu ezinye iingxaki, uninzi lwazo zinxulumene inkonzo lokucoca ulwelo ngokwayo. Njengoko izixhobo processing igesi iyasuleleka kwaye ifuna zokucoca. Kwiimeko ezigqithisileyo, filter kwamaqondo eparticulate zisusiwe kwaye ifakwe endaweni yazo kumacandelo ezintsha aftertreatment.

Icebo lokucoca ulwelo

Le block ifakwa emva kokuba converter encedisa ukuqalisa imisebenzi. Amanye amacebo zivumele yokwahluka zidityaniswe yayo noshowo kunye namachibi kuvala. Kwiimeko ezinjalo kubhaliwe esemva obuziintlobo zeemoto, apho kukho ubushushu igesi ubuninzi. Ilungu iphambili isizalo ibekwe ngendlela istili yesinyithi. Iimodeli ezisemgangathweni ngayo wenziwe lesilicon khabhayithi, nto leyo yahluke ukusuka isakhiwo zeselula lamajelo ezincinane icandelo cross. Eneneni, isakhiwo aneentunja yeendonga ecaleni kula imiphantsi kwaye inika yokusulungekiswa. Okubalulekileyo, i filter diesel kwamaqondo eparticulate nje inxalenye lonke uluhlu iinkqubo kunye nezixhobo ababandakanyekayo ukuhamba. Kweli qela nayo ibandakanya abenzi ubushushu, iyunithi amandla, ibhodi computer, kukho turbocharger kunye t. D. Enye into kukuba icebo lokucoca ezisebenza umsebenzi lokugqibela lokucoca kwaye ngoko kuthathwa njengento ephambili, ekubeni le nkungu liphumeza izinto eziphathekayo.

isimiso ukusebenza

yonke inkqubo zingahlulwa zibe ngamanqanaba amabini - ngozalisekiso ngqo yokuhluza kunye umlotha ngokutsha. In inyathelo lokuqala amasuntswana carbon abamnyama buyabanjwa, kwaye emva koko zifakwe ezindongeni lokucoca ulwelo. Kulo mba, i yingxaki kakhulu amasuntswana amancinane ukuya ku-1 micron, njengoko ubunzima yabo kuthintela yamabanjwa. Nangona inani izinto ezinjalo yi-5% kuphela yabo bonke, ukuba nje kuyingozi kakhulu ebantwini. Noko ke, izihluzi namhlanje kwamaqondo eparticulate ukuba nikwazi ukulawula ngendlela eyiyo nokulungiswa ezinjalo amasuntswana. Sesibini isigaba ngokutsha ekufakwa izinto. Inyaniso yokuba sokuzuza lwabo kukuninzi Ayize nakanye nje yena icebo lokucoca ulwelo, kodwa kunciphisa amandla injini njengoko zokubumba sisithintelo wawo ukuya kuvala ingxingwa igesi elandelayo. Kulo mba, amanyathelo ukucoca izixhobo ke uthuthu yinxalenye mandatory yenkonzo imoto.

Ukucoca icebo lokucoca ulwelo UMSI

Olu hlobo lonyango iyaphunyezwa ngenxa amaqondo igesi zeemoto ophezulu unako ukufikelela 600 ° C. Olunye uhlobo indlela ngokutsha isixando ukwethula ongeziweyo ezahlukeneyo kwi amafutha ukuqinisekisa ukutshiswa ngokufanelekileyo uthuthu lweziko. Kule meko ke, kukho impembelelo lobushushu, kodwa kwinqanaba 400-500 ° C. imo Track ivumela wobushushu isivamvo isiphumo kwamaqondo eparticulate filter, elawula kwaye ezinye yoMgaqo-injini. Nangona kunjalo, kwiimeko ezithile yokusebenza isithuthi, ukuhluza olungenzi nto ngamampunge okanye akunakwenzeka.

Ukucoca icebo lokucoca ulwelo Active

Le ndlela ukuba ekucoceni filter, olusekelwe bume okhethekileyo gas exhaust lobushushu eliphezulu. Lokwandisa ekulondolozeni ezinjalo iimeko ngcembe umlotha ziphele. Okubalulekileyo kule zokucoca esebenzayo - ngendlela efikelela amaqondo aphezulu. Phakathi ndlela iqhelekileyo uyazimela elekhtrons kade, nangoncedo diesel stroke kunye ukufudumeza nge microwave. Kwezinye iimeko, ukucoca filter diesel yamasuntswana kwakhona avelisa heater yombane. Isixhobo ingafakwa ecaleni kwisixhobo zokucoca, kodwa ngaphambi kwesi uqwalaselo kufuneka ziqwalaselwe kokufaka ngononophelo amabakala alo. recovery esebenzayo ilawula ngoncedo boluvo - ingakumbi, izixhobo ezisetyenzisiweyo ukulinganisa ingcinezelo yaye iqondo lobushushu.

Indlela ukususa kwamaqondo eparticulate lokucoca ulwelo?

Nangona ukusetyenziswa kweenkqubo zokuhlanjululwa mihla, izihluzi le hlobo kungekudala emva koko aqalise ukuphazamisa ukusebenza enjinini. Oku kubonakaliswa awo umle ukuba singesuki iindlela ezinikiweyo. Imveliso kwezi meko kuba sichitha ifowuni. Kwaye esi siganeko lwenziwa ngokwamanqanaba amabini. Umsebenzi wokuqala manual luyenziwa, apho waqhaqhwa filter kwamaqondo eparticulate ngqo. Ixabiso inkqubo yahluka ukusuka 7 ukuya amawaka 12. Thambisani. Hi ndlela leyi, ukufakelwa icebo lokucoca ulwelo elitsha kuqikelelwa kwi 30-40 amawaka. Thambisani., Bambalwa ke nabuganga ukugqiba uhlaziyo inkqubo wokucoca le. Inyathelo lesibini iqulathe ekususeni software isixhobo Yeremiya iyunithi yolawulo injini.

isiphelo

imigangatho yokusingqongileyo ababhekisi ngokunxulumene iimoto, Kakade ke, Wazazi elizayo emntwini kwaye zifuna abavelisi aseMpumalanga kolwalathiso kakhulu enobuntu ngokwemiqathango yempembelelo kokusingqongileyo. Imveliso yokugqibela kwenye yezi nkalo kwaye abe izihluzi kwamaqondo eparticulate ukuba ukunciphisa ifuthe ezinobungozi kokusingqongileyo. Ngokwenza njalo, abaqhubi beemoto bangena kunye ufakelo entsha ezininzi iingxaki. Kwanele ukukhankanya imfuneko yokuba kubekwe iliso rhoqo ukusebenza okutsha lokucoca ulwelo. Kwimeko kwezixhobo self-lokucoca umnini imoto zaneleyo akukho okunye ukususa i ibhloko okanye azise icebo lokucoca ulwelo elitsha. Kodwa zombini ezi meko iindleko iza kuba kunqandwa.
