Vavu ya EGR - valavu ya EGR solenoid imagwira ntchito bwanji ndipo ndi ya chiyani? Kodi kuchotsa malfunction ake?

Kuchepetsa kutulutsa kwazinthu zowopsa zomwe zimayaka chifukwa cha kuyaka kwamafuta panthawi ina kunakhala gawo lalikulu pamsika wamagalimoto. Zida ndi machitidwe ambiri amagwiritsidwa ntchito pa izi, monga:

• NYANGO;
• chothandizira;
• particles fyuluta;
• AdBlue.

Zina zowonjezera mu injini ndi zowonjezera zake nthawi zambiri zimakhudza ntchito yake, ndipo ngati zimagwira ntchito bwino, siziwoneka. Pa nthawi yolakwika, zimakhala zovuta kwambiri, zomwe zimapangitsa moyo kukhala wovuta kwa madalaivala ambiri. Valavu ya EGR yowonongeka imayambitsa zizindikiro zofanana ndi turbocharger yolephera.. Ndiye, momwe mungadziwire bwino vuto mu injini yokhala ndi valavu ya EGR?

Vavu EGR m'galimoto - ndi chiyani ndipo ndi chiyani kwenikweni?

Dongosolo la EGR limayang'anira kulowetsanso mpweya wotulutsa mpweya wotuluka chifukwa cha kuyaka kwamafuta mu silinda. Akafunsidwa chifukwa chake valve ya EGR ikufunika, yankho losavuta ndilokuti lapangidwa kuti lichepetse kuchuluka kwa mankhwala owopsa a nayitrogeni-poizoni (NOx). Izi zimachitika chifukwa cha kuchepa kwa kutentha mkati mwa chipinda choyaka moto. Kuwongolera mpweya wotuluka ku injini ndikuchepetsa kutentha kwamoto kumachepetsa kuchuluka kwa makutidwe ndi okosijeni wamafuta. Dongosolo la EGR lapangidwa kuti lipange zinthu zovuta kwambiri zophatikiza mpweya ndi nayitrogeni, zomwenso ndikuchepetsa kuchuluka kwa mpweya woipa..

EGR ntchito mu injini

Valavu ya EGR solenoid si chipangizo chosiyana, koma ndi dongosolo lomwe limayang'anira kutulutsa mpweya wotulutsa mpweya.. Komabe, nthawi zambiri zimagwirizanitsidwa ndi valve ya EGR, yomwe imayambitsa mavuto ambiri. Ili pakati pa manifolds olowa ndi utsi. Makamaka m'mainjini akuluakulu amafuta ndi magalimoto okhala ndi dizilo, imakhala ndi kuziziritsa kwina. Izi ndizofunikira chifukwa cha mpweya wotentha kwambiri womwe umatuluka m'chipinda choyaka komanso kufunikira kowongolera kuchuluka kwa iwo m'menemo.

Njira yogwiritsira ntchito EGR ndi yopapatiza chifukwa valavu ya EGR palokha siitsegula nthawi zonse. Mothandizidwa ndi chizindikiro cholandira kuchokera kwa wolamulira injini, EGR imatsegula, ndikuyendetsa bwino kutuluka kwa mpweya wotulutsa mpweya. Izi zimachitika pokhapokha pa injini yamagetsi, chifukwa jekeseni wa mpweya wotulutsa mpweya mu chipinda choyaka moto amachepetsa kuchuluka kwa mpweya, motero amachepetsa ntchito ya unit. EGR m'galimoto siigwira ntchito mopanda pake, mumayendedwe ang'onoang'ono komanso pamlingo waukulu.

Vavu ya EGR - momwe mungayang'anire ngati ikugwira ntchito?

Ndikofunikira kulumikiza njira yowunikira kuti muwonetsetse kuti valavu ya EGR ikugwira ntchito.. Ngati mulibe mwayi wopeza, mutha kungopita kumalo okonzera magalimoto apafupi. Komabe, kumbukirani kuti mtengo wa diagnostics amenewa ndi osachepera makumi angapo zł, malinga ndi chitsanzo galimoto.

Zizindikiro za valavu ya EGR yowonongeka

Zizindikiro za EGR yowonongeka ndizowoneka bwino komanso zowonekera. Kulephera kwa EGR kumayambitsa:

• kuchuluka kwa utsi wakuda kuposa ma dizilo;
• mwadzidzidzi kapena kutaya mphamvu kwathunthu;
• malo ogulitsa magalimoto osagwira ntchito. 

Zikatero, nthawi zambiri ndikofunikira kuyeretsa EGR.. Monga chomaliza, valavu ya EGR iyenera kusinthidwa.

Momwe mungayeretsere valavu ya EGR?

Simukuyenera kupita kwa makina kuti muyeretse valavu ya EGR. Ngati muli ndi chidziwitso chaching'ono chamagalimoto ndi makiyi ochepa, mutha kuchita bwino nokha. Kusintha sikofunikira pamatembenuzidwe a pneumatically actuated, komabe, kungafunike kuti mavavu amakono oyendetsedwa ndimagetsi, kulepheretsa kudzikonza koyenera.

Kodi mukufunikira chiyani kuti muyeretse valavu ya EGR nokha? 

Choyamba, choyeretsa (mwachitsanzo, mafuta opangira mafuta kapena nitro thinner), burashi, ma wrenches otsegula valavu (nthawi zambiri hex) ndi gaskets. Monga tafotokozera pamwambapa, yang'anani chipangizochi pakati pa manifold otopetsa ndi ma intake. Pambuyo pochotsa ndi kuchotsa, ndikofunika kwambiri kuyeretsa gawo lokha lomwe limayambitsa kusuntha valavu, osati zinthu za pneumatic ndi diaphragm. Amapangidwa ndi mphira ndipo amatha kuonongeka ndi madzi aukali.

Musadabwe ngati mutatha disassembly muwona mwaye wambiri. Njira yabwino ndiyo kukonzekera chidebe chachikulu, koma chozama, chomwe valavu ya EGR imamizidwa ndikusiyidwa kwa maola angapo kapena tsiku. Mwanjira iyi goo lakuda lidzasungunuka ndipo mutha kuyeretsa ma nooks onse ndi burashi. Ntchitoyo ikatha, onetsetsani kuti mwapereka EGR kupukuta bwino musanayiike m'galimoto.. Dziwani ma gaskets atsopano.

Momwe mungayeretsere EGR popanda disassembly?

Zogulitsa zomwe zilipo pamsika zimalola kuchotsedwa kwa ma depositi a kaboni ndi zonyansa zina popanda kugwetsa zigawo. Inde, padzakhala anthu ambiri ochirikiza ndi otsutsa chisankho chotero, ndipo aliyense wa iwo adzakhala wolondola pang'ono. Kukonzekera mwa mawonekedwe a kupopera kumagwiritsidwa ntchito ku dongosolo la kudya komwe kulipo, malingana ndi kufunikira koyeretsa gawo linalake. Kugwiritsa ntchito kumachitika pa injini yothamanga komanso yotentha molingana ndi malangizo a wopanga. Nthawi zina, m'malo moyeretsa, zikhoza kuchitika kwa wina kuti asokoneze valve ya EGR. Kodi zikuphatikizapo chiyani?

Jamming EGR - zotsatira zoyipa. Kodi kukonza kumafunika liti?

Kwa madalaivala ena, kupanikizana kwa EGR kumangokhala ndi zotsatira zabwino - utsi wochepa, palibe mavuto ndi kusinthasintha kwa injini ndi kuchotsa jerks. Komabe, sikuti zimangoyendetsa galimoto, chifukwa dongosololi likugwirizana ndi khalidwe la mpweya wotulutsa mpweya. EGR imachepetsa kutulutsa kwa zinthu zoopsa, chifukwa chake ndikofunikira kutsatira malamulowo. M'magalimoto amakono, omwe, kuwonjezera pa valavu yokha, amakhalanso ndi sensa ya malo ndikuyang'anira mlingo wa mphamvu yowonjezera, kuyika pulagi mu valve kudzakhudza ntchito ya msonkhano. Zikatero, ntchitoyi iyenera kuchitidwa ndi makanika wodziwa bwino ntchito zamagetsi.

Kodi zotsatira za kusalemba EGR ndi zotani? Kwenikweni iwo amakhudza kuyendera luso. Ngati diagnostician, poyendera galimoto, detects kuphwanya opareshoni (makamaka, kusowa ntchito) wa utsi mpweya valavu recirculation, iye sadzakweza anayendera. Kuphatikiza apo, kulephera kutsatira malamulo okhwima a utsi kumalangidwanso ndi apolisi. M'magalimoto omangidwa kuti akwane, eni ake amatha kuyembekezera chindapusa cha PLN 5.

EGR shutdown kapena EGR valve m'malo?

Ngati galimotoyo ndi yakale ndipo galimoto ilibe sensa ya EGR, kutsegula valve ya EGR ndikosavuta. Kuphatikiza apo, kusintha valavu ya EGR kumatha kukhala okwera mtengo kwambiri. EGR solenoid ikhoza kukhala yokwera mtengo, monganso ntchito. Chilichonse chikhoza kukhala ma zloty mazana angapo. M'malo molipira kuti mugule gawo latsopano ndikusintha valavu ya EGR, ena amasankha kuika.

EGR solenoid vavu pulagi pa dizilo ndi mafuta ndi zotsatira

Mtengo wokwera m'malo mwa valavu ya EGR, chikhumbo chopewa kubwereza molunjika mmwamba m'tsogolomu - zonsezi zimapangitsa madalaivala ambiri kusankha kukhala akhungu, i.e. kuletsa EGR. Kodi ili ndi zotsatirapo zilizonse? Kodi chimachitika ndi chiyani mukathimitsa valavu ya EGR pa injini ya dizilo kapena petulo? Mwina... palibe. Chotsatira chozimitsa valavu ya EGR solenoid chikhoza kukhala kuwala fufuzani injini. M'magalimoto atsopano, zotsatira zolepheretsa EGR zitha kuchepetsedwa kupindula kwa liwiro lapakati pa liwiro lapakati.

Ngati mukufuna kuti dongosolo la EGR, kuphatikizapo EGR valve ndi sensa, lizigwira ntchito mopanda malire kwa nthawi yayitali, yesetsani kuyeretsa EGR solenoid valve nthawi zonse.
