Musiyano uripo pakati pe spark plugs: single, 2, 3 uye 4 pini
Zviri mukati
Maererano nevatyairi vakawanda, makenduru akadaro ndiyo yakanakisa sarudzo maererano nemutengo / mhando reshiyo. Vane 2 side electrodes mukugadzirwa kwavo, iyo isingafukidze muromo uye haidziviriri zvakanyanya magasi anopisa kubva pakuchenesa muviri we insulator. Murazvo unobva pa spark zvakaenzana unopinda mukamuri inopfuta, kuve nechokwadi chekushanda kwakagadzikana kwepiston.
Kana mubvunzo ukamuka, makenduru e-single-contact anosiyana sei kubva ku2, 3 uye 4-contact, ipapo mhinduro iri pachena - nhamba yemativi emagetsi. Mukuwedzera, mhando dzine "petals" dzakawanda dzine hupenyu hurefu hwebasa.
Chii chinopa makenduru ega-pini
Zvigadzirwa izvi zvino zvanyanya kuwanda. Ivo vane mukurumbira nekuda kwemutengo wavo wakaderera uye yakaderera mafuta emhando zvinodiwa. Makenduru akadaro anoshanda nemainjini emota zhinji: kubva kumotokari dzepamba dzakashandiswa kuenda kumota nyowani dzekunze.
Dhizaini yemuenzaniso iri nyore kwazvo:
- Pamusoro pane chena ceramic kesi.
- Pazasi pane girazi resimbi rine shinda.
- The tip, pamusoro iyo inorembera 1 "petal".
Chigadzirwa chacho chinoputirwa nyore nyore mukenduru zvakanaka. Mukaha uripo pakati peiyo huru uye parutivi electrodes kazhinji 0,8-1,1 mm. Chinhambwe ichi chinowedzera nekufamba kwenguva sezvo simbi inopera nekubuda kwega kwega kwekoiri, zvichikonzera kusapfurwa.
Nzira yekusarudza spark plugs
Naizvozvo, izvo zvinonyanya kukanganisa zve-single-contact makenduru ndezvi:
- low resource reserve (mhangura uye nickel zvigadzirwa zvinokwana kumhanya kwe15-30 zviuru zvemakiromita);
- kusagadzikana mukupenya (kunyanya munguva yechando).
Kuti ive nechokwadi chekuumbwa kwemoto wakavimbika uye kuwedzera simba rekuchaja, vagadziri vanodzikisa dhayamita yetipi (kubva pa2,5 kusvika 0,4 mm). Pamusoro pezvo, yakaputirwa nealloy yesimbi dzakanaka (platinum, iridium, yttrium), iyo inoderedza kupfekedzwa kweka 2-3 nguva. Uyewo, kuitira kuti uderedze simba rekudzima uye kuve nechokwadi chekupisa kwakazara kwemafuta, U-groove inoshandiswa kune rutivi rwekubatana, uye V-chimiro chinopiwa kune electrode yepakati.
Zvinhu zvakasiyana zve spark plugs
Kuti kuderedze kupfeka kwechigadzirwa, vagadziri, kunze kwekushandisa zvinhu zvinokosha, vakatanga kubudisa mienzaniso nemagetsi akawanda. Zvigadzirwa zvinonyanya kufarirwa ndezveNgk, Bosh, Denso, Brisk.
Matatu-pini
Iyi mhando ye spark plug inowanzoshandiswa mukati memutengo wemotokari injini. Vanovimbisa kugadzikana kwemoto kuumbwa, asi vari kunyanya kudiwa pamhando yehuni. Negasi rakaipa, ivo havazogara kupfuura makenduru akajairwa.
Dzimwe nyanzvi dzinoti hupenyu hwe-3-contact zvigadzirwa hurefu zvakapetwa kakati wandei pane zvezvigadzirwa zvemunhu mumwe chete. Chokwadi, mativi "petals" anodzimwa zvakaenzana, sezvo spark ichirova neimwe nzira kune iri pedyo painopera. Asi zvakakosha kunzwisisa kuti, kutanga kwezvose, muromo wepakati unoiswa pasi pekukukurwa kwemagetsi. Muganho waro wekuchengeteka unoenderana nezvinhu. Semuenzaniso, kana spike yakagadzirwa neiridium, ipapo chigadzirwa chichagara kusvika 90 zviuru zvemakiromita.
Vaviri-kusangana
Maererano nevatyairi vakawanda, makenduru akadaro ndiyo yakanakisa sarudzo maererano nemutengo / mhando reshiyo. Vane 2 side electrodes mukugadzirwa kwavo, iyo isingafukidze muromo uye haidziviriri zvakanyanya magasi anopisa kubva pakuchenesa muviri we insulator. Murazvo unobva pa spark zvakaenzana unopinda mukamuri inopfuta, kuve nechokwadi chekushanda kwakagadzikana kwepiston.
Ina-pini
Mukugadzirwa kwezvigadzirwa izvi, pane 2 peya dzemagetsi ane gap re 0,8 mm uye 1,2 mm, zvichiteerana. Nekuda kwechimiro ichi, makenduru akakodzera kune akawanda carburetor uye jekiseni injini.
Spark plugs dzakasiyana
Makenduru aya akashata kupfuura mamwe mamodheru, anocheneswa soot uye anogadzira murazvo wakaderera pakumhanya kwakaderera. Asi nerumwe rutivi, ivo vane hombe resource reserve (kunyanya ne iridium sputtering). Izvi zvinokonzerwa nekuti 4 mativi ekubatanidza anogadzika kubva pamagetsi emagetsi. Mukuwedzera, ivo havafukidze nzvimbo iri pamusoro pechipimo, iyo inovimbisa kugovaniswa kwemoto kubva pamoto. Nekuda kweizvi, mutoro pamadziro episton wakaenzana.
Vamwe varidzi vemotokari vanoti mushure mekuisa makenduru e-multi-electrode, vakacherechedza zvinotevera:
- hapana matambudziko nekutanga motokari kunyange munguva yechando;
- yakawedzera injini simba ne2-3%;
- kuderedza kushandiswa kwemafuta ne 0,4-1,5%;
- magasi ekupedza akadzikira ne4-5%.
Mukuwedzera, mamwe injini dzakagadzirirwa kune imwe chete-kusangana nenzvimbo ye "petal" pamusoro pechipiko, kuitira kuti kubudiswa kuri pamwe chete neaxis. Mamwe ma motors anoda side clearance. Nokudaro, kusarudzwa kwemuenzaniso wakakodzera kunofanira kuitwa pamwe chete nenyanzvi, kana zvisina kudaro matambudziko achamuka mukushanda kwemotokari.
