Nzira yekutarisa valve yekuchenesa ne multimeter

Ivhavha yekuchenesa chikamu chemotokari yeEvaporative Emissions Control (EVAP) system. Iyo meshini inobatsira kudzivirira hupfu hwehutsi hunogadzirwa neinjini kubva mukupukunyuka mumhepo kana kudzokera mumotokari. Anoachengeta kwenguva pfupi mugaba remarasha. Iyo valve inobatsirawo kudzora huwandu hwehutsi hwehutsi hunozopeperetswa kubva mugaba remarasha.

Mumotokari dzemazuva ano, sisitimu iyi ndeyemagetsi inodzorwa solenoid yakabatana kune injini simba. Ivhavha yekuchenesa zvishoma nezvishoma inotendeuka pakarepo kana moto wabatidzwa, asi EVAP system haishande kana injini yadzimwa.

Pane dzimwe nguva apo iyo system inotadza, izvo zvinokuvadza hutano hwemota yako! Izvi zvinoshanda kana iwe uchiziva nzira yekuyedza vharafu yekuchenesa ine multimeter. Kunze kweizvi, tichakurukurawo pfungwa dzinotevera: 

• Mhedzisiro yekutadza kweiyo adsorber purge valve
• Ko vharafu yekuchenesa inofanira kudzvanya here?
• Ko vharafu yekugezesa yakaipa inogona kukonzera moto usina kunaka

Nzira dzekuyedza vharafu yekuchenesa ine multimeter

Iyo yakanyatso kutumidzwa zita rekuti multimeter chishandiso chinoshanda chinogona kuyera voltage, kuramba, uye magetsi aripo.

Kuti uedze valve yekuchenesa, tarisa kushorwa pakati pematerminals.

Maitiro anogona kusiyana zvichienderana nemhando yemotokari, asi matanho ekutanga anoramba akafanana.

Akanyorwa pazasi ndiwo matanho akajairwa anogona kushandiswa kuyedza vharafu yekuchenesa iyo iri chikamu cheiyo EVAP system: 

1. Kutsvaga nzvimboChinhu chekutanga kuita kudzima injini kweinenge 15-30 maminetsi. Mushure maizvozvi, edza kutsvaga mavharuvhu ekuchenesa emotokari. Zvakanaka, inogona kuwanikwa kuseri kwemuffler kana muffler uye yakamira pamusoro. Iyi iEVAP kabhoni sefa ine vharafu yekuchenesa mukati. Kuti uwane rumwe ruzivo nezve nzvimbo yehurongwa, edza kutsvaga bhuku remuridzi wemotokari kana kutsvaga modhi yepamhepo ine mufananidzo weinjini.
2. Cable kugadzirisaKana iwe uchinge wawana iyo yekuchenesa vharafu, iwe uchaona kuti 2-pini harness yakabatana kune mudziyo. Nhanho inotevera ndeyekubvisa uye kuvabatanidza zvakare uchishandisa multimeter adapter tambo dzinowanzo kuverengerwa muyedzo kit. Vanogonawo kutengwa zvakasiyana. Iyo yekugezesa valve terminals inofanirwa kubatanidzwa kune multimeter tambo.
3. Kuedza Nhanho yekupedzisira ndeyekuyera kuramba. Mazinga akakodzera anofanira kunge ari pakati pe22.0 ohms uye 30.0 ohms; chero chinhu chakakwirira kana chakaderera chinoreva kuti valve inoda kutsiviwa. Izvi zvinogona kuitwa pane saiti kana uine spare; kana zvisina kudaro, kana uchida kuenda nayo kuchitoro, iva nechokwadi chekubatanidza tambo dzewaya sepakutanga.

Ndinoziva sei kana vharuvhu yangu yekuchenesa yakashata?

Pane zvakawanda zviratidzo zvekusashanda EVAP system. Chenjerera kune:

Chiedza cheinjini Injini inodzora purge solenoid uye kana chimwe chinhu chikatadza, mwenje weinjini uchauya. Kana yakakwira kana yakaderera nhanho yekuchenesa mhute yakaonekwa, kukanganisa makodhi anoratidzwa, kusanganisira P0446 kana P0441. Tinokurudzira kuendesa mota kuchitoro chekugadzirisa kana ukaona zviratidzo zviri pamusoro.

Matambudziko einjini Kana vharafu yekuchenesa isina kuvharwa, chiyero chemhepo-mafuta chinogona kukanganiswa zvakanyanya nekupukunyuka kwemhute kune zvakatipoteredza. Injini inopindura kune shanduko, zvichikonzera kuoma kwekutanga kana hutsinye idling.

Kunyanya kushandiswa kwepeturu Kana iyo EVAP system isiri kushanda nemazvo, inoderedza gasi mileage. Panzvimbo pekuunganidza muvhavha yekuchenesa, mhute yemafuta inotanga kupinda mumhepo, zvichiita kuti kupisa kwemafuta kuwedzere.

Kuita kwakashata muyedzo yekunze Iyo EVAP canister ine basa rekudzoreredza hupfu hwehutsi kudzokera kunjini. Izvi zvinobatsira kudzivirira kuburitswa kwehutsi hunokachidza munzvimbo. Muchiitiko che solenoid yakashata, haizokwanisi kudzora utsi uye kukundikana kuedza kwekubudisa.

Mapedhi akaparadzwa Sezvo mhute isingakwanisi kupfuura kana valve ikakundikana, kumanikidzwa kunotanga kuvaka. Nekufamba kwenguva, ichave yakanyanya kusimba zvekuti inogona kuburitsa zvisimbiso zverabha uye gaskets. Mhedzisiro ichave yekudonha kweoiri, iyo inogona kupinda muinjini huru kubva kune exhaust system, zvichikonzera kukuvara kwakanyanya. Chikonzero chinowanzoita kuti vharafu yekuvhuvhuta ishande zvakanaka ndechekuti zvidimbu zvekabhoni kana zvinhu zvekunze zvakanamira, zvichisiya michina yakavharwa kana kuvhurika. Inoda kutsiviwa kana kucheneswa.

Ko vharafu yekuchenesa inofanira kudzvanya here?

Mhinduro pfupi kumubvunzo ndihongu! Ivhavha yekuchenesa inowanzoita kudzvanya kana kukwenya ruzha. Zvisinei, mumotokari ine mahwindo akavharwa, haifaniri kuonekwa. Kana ikawedzera ruzha uye inogona kunzwika mukati memotokari, inogona kuva chikonzero chekunetseka. Iyo solenoid inoda kuongororwa.

Imwe nzira ndeyokuti valve yekuchenesa yakatanga kupinza mhute muinjini kana ichiwedzera mafuta. Izvi zvinotungamira kune yakaoma kutanga uye nyaya sezvataurwa pamusoro apa.

Ko vharafu yekugezesa yakaipa inogona kukonzera kukanganisa?

 Ivhavhavha yekuchenesa inogona kutungamirira kumoto usina kunaka kana mamiriro acho akasiyiwa asina kutarisirwa kwechinguva. Sezvo utsi hunotanga kukwira zvakanyanya muEVAP system kana mufirita yemarasha, vharuvhu haizokwanisi kuvhura nenguva.

Kana maitiro akaenderera mberi nekufamba kwenguva, utsi hunopinda mumasilinda einjini, zvichikonzera kutsva kwehuwandu husina kujairika hwehutsi nehutsi. Musanganiswa uyu uchaita kuti injini imire uye yobva yadzima moto. (1)

Kutonga kwekupedzisira

Iyo solenoid valve chinhu chakakosha chemotokari. Kana ukaona chimwe chezvinetso zvakanyorwa pamusoro apa, motokari inofanira kugadzirwa nokukurumidza. Kana iwe uchida kuedza kanister iwe pachako, unogona kutevera matanho ane multimeter uye chigadziro chichakuudza kana iwe une valve yakaipa! (2)

Sezvo takakuratidza nzira yekutarisa valve yekuchenesa ine multimeter, iwe unogona zvakare kutarisa. Iwe ungangoda kutarisa yakanakisa multimeter yekusarudza gwara uye sarudza kuti ndeipi inokodzera zvaunoda kuyedza.

Tinovimba chinyorwa ichi chekudzidzisa chichakubatsira. Rombo rakanaka!
