EGR vharafu ndiwo moyo weinjini yekubuda mushure mekurapa system. EGR ipfupi yeExhaust Gasi Recirculation, uye ndizvo chaizvo zvainoita. Ichi chinoshamisa chine hushamwari hwezvakatipoteredza chinovhura pane mamwe mamiriro ekushanda kweinjini uye chinobvumira magasi emhepo kuti adzokororwe kuburikidza neinjini kechipiri. Iyi nzira inoderedza zvakanyanya kubuda kunokuvadza kwenitrogen oxides (NOx), iyo inobatsira zvikuru pakuumbwa kwehutsi. Muchikamu chino, uchawana ruzivo pamusoro pebasa reEGR valve, uyewo nzira yekuchenesa valve uye nei inowanzoda kucheneswa kana kuchinjwa.
EGR valve inorarama hupenyu hwakaoma. Kutaura zvazviri, zvichida chimwe chezvikamu zvakaoma zvikuru zvejini yemazuva ano. Iyo inogara ichirangwa nekupisa kwakanyanya kunogona kugadzira mota uye yakavharwa nezvidimbu zvemafuta asina kupiswa, anozivikanwa zviri nani secarbon. Iyo EGR vharafu yakatetepa zvekuti inogona kudzorwa nejini vacuum kana komputa, ichikwanisa kushingirira 1,000-degree carbon-laden exhaust gasi tembiricha pese injini iri kushanda. Zvinosuruvarisa, pane muganhu kune zvose, kusanganisira EGR valve.
Mushure mezviuru zvematenderedzwa, kabhoni inotanga kuisa mari mukati meEGR valve, ichidzikamisa kugona kwevhavha kuita basa rayo seEGR muchengeti wegedhi. Aya madhipoziti ekabhoni anowedzera kukura uye kukura kusvika EGR valve yamira kushanda nemazvo. Izvi zvinogona kutungamirira kumatambudziko akasiyana-siyana ekubata, hapana chimwe chazvo chinodiwa. Kana kusashanda uku kuchiitika, kune mishonga miviri mikuru: kuchenesa EGR valve kana kutsiva EGR valve.
Chikamu 1 che2: Kuchenesa EGR valve
Zvinhu zvinodiwa
- Basic maturusi emaoko (ratchets, sockets, pliers, screwdrivers)
- Carburetor uye throttle cleaner
- Scraper gasket
- tsono mhuno pliers
- Rubber magurovhosi
- Magirazi ekuchengetedza
- bhurasho duku
Danho 1 Bvisa zvose zvinobatanidza magetsi.. Tanga nekubvisa chero zvibatanidza zvemagetsi kana mahosi akabatanidzwa paEGR valve.
Danho rechipiri: Bvisa EGR valve kubva mujini.. Kuoma kwedanho iri kunoenderana nerudzi rwemotokari, pamwe nenzvimbo uye mamiriro evhavha.
Iyo inowanzo ine maviri kusvika mana mabhaudhi akaibata kune inopinza manifold, silinda musoro, kana exhaust pombi. Sunungura mabhaudhi aya uye bvisa EGR vharafu.
Nhanho 3: Ongorora mavharuvhu machiteshi kuti akavharika uye madhipoziti.. Ongororawo zviteshi zvinoenderana painjini pachayo. Vanowanzovharwa nekabhoni zvakada kufanana nevhavha pachayo.
Kana yakavharika, edza kubvisa zvidimbu zvihombe zvekabhoni nemhuno dzetsono. Shandisa carburetor uye throttle body cleaner pamwe chete nebhurasho diki kuchenesa chero yasara.
Danho rechina: Ongorora EGR vharafu kune madhipoziti.. Kana iyo valve yakavharwa, nyatsoichenesa ne carburetor uye choke cleaner uye brashi duku.
Danho rechishanu: Tarisa uone kukuvara kwekupisa. Ongorora iyo EGR vharafu yekukuvara kunokonzerwa nekupisa, zera uye zvechokwadi kabhoni kuvaka.
Kana yakakanganiswa, inofanira kutsiviwa.
Danho rechitanhatu: Geza EGR valve gasket.. Chenesa gasket nzvimbo paEGR valve uye injini ine gasket scraper.
Chenjerera kuti usatore zvidimbu zvidiki zvegasket muEGR ports padivi reinjini.
Nhanho yechinomwe: Tsiva iyo EGR gaskets.. Kana zvese zvacheneswa nekuongororwa, tsiva iyo EGR gasket (s) uye uisungirire kune injini kune zvakatemwa fekitori.
Danho rechipiri: Tarisa kuti pane mvura here. Tarisa kushanda zvinoenderana nefekitari sevhisi bhuku uye tarisa vacuum kana exhaust inodonha.
Chikamu 2 che2: EGR vharafu kutsiva
EGR mavharuvhu dzimwe nguva anogona kunetsa kutsiva nekuda kwezera, mamiriro, kana rudzi rwemotokari pachayo. Kana uchinetseka nematanho ari pasi apa, zvinogara zvakanaka kuti uone nyanzvi.
Zvinhu zvinodiwa
- Basic maturusi emaoko (ratchets, sockets, pliers, screwdrivers)
- Scraper gasket
- Rubber magurovhosi
- Magirazi ekuchengetedza
Danho 1 Bvisa chero zvibatanidza magetsi kana hosi.. Tanga nekubvisa chero zvibatanidza zvemagetsi kana mahosi akabatanidzwa paEGR valve.
Nhanho yechipiri: Bvisa mabhaudhi anochengetedza EGR vharafu kune injini.. Kazhinji pane kubva maviri kusvika mana, zvichienderana nemotokari.
Danho rechitatu: Bvisa zvinhu zvegasket kubva panzvimbo yekusangana. Chengetedza marara kunze kweEGR port yeinjini.
Danho rechina: Isa itsva EGR vharafu uye valve gasket.. Isa itsva EGR valve gasket uye EGR vharafu kune injini kune fekitori yakatarwa.
Danho 5: Batanidzazve Hoses kana Magetsi Connections.
Nhanho 6: Ongororazve system yako. Tarisa kushanda zvinoenderana nefekitari sevhisi bhuku uye tarisa vacuum kana exhaust inodonha.
EGR mavharuvhu ari nyore mumashandiro aanoita, asi kazhinji hazvisi nyore kana zvasvika pakutsiva. Kana usiri kusununguka kutsiva EGR vharafu iwe pachako, iva nemakanika ane hunyanzvi seAvtoTachki kutsiva EGR vharafu yako.
