Zigawo Zing'onozing'ono, Kukhudza Kwambiri: Ntchito ndi Kusamalira Zolakwika za Mapulagi a Spark a Magalimoto
Mu "mtima" wa injini ya petulo ya galimoto, ngakhale kuti pulagi ya spark ndi yaying'ono, imagwira ntchito yofunika kwambiri komanso yofunika kwambiri. Ili ngati "mtsogoleri wa kuyatsa" kwa injini, yomwe imagwira ntchito ngati malo olumikizira mphamvu zamagetsi ndi mphamvu zamakanika. Kugwira ntchito kwake kumakhudza mwachindunji mphamvu ya injini, kusunga mafuta moyenera, komanso kukhazikika kwa galimotoyo.
Ntchito Yaikulu ya Ma Spark Plugs
Ntchito yofunika kwambiri komanso yofunika kwambiri ya spark plug ndiyo kuyatsa chisakanizo choyaka mu silinda, zomwe zimapereka mphamvu yogwirira ntchito ya injini. Kumapeto kwa injini, ma electrode a spark plug amapanga arc yamagetsi amphamvu, nthawi yomweyo kuyatsa chisakanizo cha mpweya wopanikizika. Njirayi ndiyo poyambira ntchito ya injini, ndipo kuyaka kwa mpweya wotentha kwambiri komanso wopanikizika kumakankhira pistoni pansi, motero kumayendetsa crankshaft kuti izungulire, zomwe zimapatsa galimoto mphamvu yopitilira. Nthawi zambiri, injini ya masilinda anayi imakhala ndi ma spark plug anayi, pomwe injini ya masilinda asanu ndi limodzi imafuna 6, ndipo imodzi pa silinda iliyonse kuti iwonetsetse kuti njira yoyaka yokhazikika komanso yolongosoka ya silinda iliyonse.
Kuwonjezera pa kuyatsa moto, ma spark plugs amakhudzanso mphamvu ya injini komanso kugwiritsa ntchito mafuta. Ma spark plugs abwino kwambiri amatha kuonetsetsa kuti chisakanizocho chikuyaka bwino, ndikuwonjezera kusalala kwa mphamvu zomwe zimatulutsa komanso kuchepetsa kugwiritsa ntchito mafuta. Ngati spark plug ikakalamba, monga kuwonongeka kwa ma electrode kapena carbon deposits, imayambitsa kuyatsa moto mochedwa kapena kufooka, zomwe zimapangitsa kuti chisakanizocho chisayaka bwino, osati kungochepetsa mphamvu komanso kuwonjezera kugwiritsa ntchito mafuta ndi 10%-20%. Komanso, ma spark plugs ali ndi ntchito yowongolera njira yoyatsira moto, posintha nthawi yoyatsira moto ndi mphamvu, amatha kusintha bwino zosowa za injini m'mikhalidwe yosiyanasiyana yogwirira ntchito. Pa liwiro lotsika, imatha kuwongolera bwino nthawi yoyatsira moto kuti iwonjezere kugwiritsa ntchito mafuta bwino; pa liwiro lokwera, imatha kupereka mphamvu zokwanira mwachangu kuti zisakanizo ziyaka mwachangu ndikutulutsa mphamvu yamphamvu.
Ntchito zoziziritsira ndi zotetezera kutentha za ma spark plugs siziyenera kunyalanyazidwa. Gawo la ceramic la spark plug limagwira ntchito zofunika kwambiri monga kufalitsa kutentha ndi kutetezera kutentha, zomwe zimatha kufalitsa kutentha komwe kumapangidwa ndi electrode yapakati mwachangu, kuteteza electrode kuti isatenthe kwambiri ndikuwonjezera nthawi ya moyo wa spark plug; nthawi yomweyo, imatseka kutentha kwakukulu m'chipinda choyaka moto, ndikuwonetsetsa kuti malo ogwirira ntchito a electrode yapakati ndi abwinobwino. Kuphatikiza apo, ma spark plugs amatha kuwonetsa momwe injini imagwirira ntchito. Mwachitsanzo, akakhala ndi carbon deposits, nthawi zambiri zimasonyeza kuti injini ili ndi vuto, monga kuchuluka kwa carbon deposits zomwe zikusonyeza vuto ndi makina ojambulira mafuta, kapena kutopa chifukwa cha makina oyatsira osazolowereka.
Zolakwika ndi Mayankho Ofala a Ma Spark Plugs
Mukagwiritsa ntchito ma spark plug kwa nthawi yayitali, zolakwika zosiyanasiyana sizingapeweke, zomwe zimakhudza magwiridwe antchito abwinobwino a injini. Zolakwika zomwe zimachitika nthawi zambiri ndi monga mavuto oyatsa moto, kugwedezeka kwa injini, kusowa mphamvu, kugwiritsa ntchito mafuta ambiri, komanso kutulutsa utsi woipa.
Kuwonongeka kwa ma electrode ndi chimodzi mwa zolakwika zomwe zimachitika kwambiri pa ma spark plugs. Pamene injini ikukalamba, electrode yapakati ndi electrode ya mbali ya spark plug zidzawonongeka chifukwa cha kukokoloka kwa magetsi kwa nthawi yayitali komanso dzimbiri la mankhwala kuchokera ku mpweya woyaka, zomwe zimapangitsa kuti kusiyana kwa ma electrode kuchuluke. Pamene kusiyanako kupitirira 2mm, mphamvu yoyendetsera magetsi imachepa, ndipo ma spark otulutsidwa amakhala ochepa kwambiri, zomwe zimapangitsa kuti nthawi yoyatsira ichepe komanso kuyaka kosakwanira kwa chisakanizocho, zomwe zimapangitsa kuti mafuta azigwiritsidwa ntchito kwambiri, mphamvu ichepe, komanso nthawi zina, ngakhale kulephera kupanga ma spark, zomwe zimapangitsa kuti silinda isagwire bwino ntchito. Nthawi zina, spark plug yatsopano imafunika.
Ma carbon deposits nawonso ndi "mdani" wa ma spark plugs. Kuchuluka kwa carbon deposits ndi dothi lomwe limasonkhana pamwamba pa spark plug kumachepetsa mphamvu yake yamagetsi, zomwe zimakhudza kuyaka. Ma carbon deposits nthawi zambiri amakhudzana ndi mafuta osakwanira, kusakaniza kolemera kwambiri, komanso zosefera mpweya zotsekeka. Ngati mupeza carbon deposits pa spark plug, mutha kuyesa kuyeretsa kaye. Ngati carbon deposits ndi yayikulu kapena spark plug ikadali yosagwira ntchito bwino mutatsuka, muyenera kusintha spark plug. Nthawi yomweyo, muyenera kufufuza chomwe chimayambitsa carbon deposits, monga kusintha mafuta abwino kwambiri kapena kuyang'ana makina ojambulira mafuta kuti muthetse vutoli komwe kumachokera.
Kuphatikiza apo, ma spark plugs angakhalenso ndi mphamvu zochepa zotetezera kutentha, kuwonongeka kwa siketi, ndi zolakwika zotuluka. Ngati mphamvu zotetezera kutentha zili zochepa kwambiri, zimachepetsa mphamvu yoyatsira yomwe imagwiritsidwa ntchito pa spark gap, zomwe zimapangitsa kuti spark ikhale yofooka kapena kutaya ntchito yake yoyatsira; ming'alu mu siketi imapangitsa kuti mphamvu yamagetsi yapamwamba iwonongeke ndikutulutsa magetsi kudzera m'dera losweka, zomwe zimapangitsa kuti spark isatuluke pa electrode; kutayikira nthawi zambiri kumachitika chifukwa cha zolakwika kapena kuwonongeka kwa ceramic insulator ya spark plug kapena electrode gap yambiri. Zolakwika izi nthawi zambiri zimafuna kusinthidwa kwa spark plug nthawi yake, ndipo mukayisintha, ndikofunikira kusamala posankha mtundu womwe ukugwirizana ndi injini ya galimotoyo kuti muwonetsetse kuti kutentha kwake, mawonekedwe a ulusi, ndi magawo ena akukwaniritsa zofunikira.
Kukonza ndi kusintha ma spark plugs
Kuti muwonetsetse kuti pulagi ya spark ikugwira ntchito bwino komanso kuti ikule nthawi yayitali, kukonza nthawi zonse komanso kusintha nthawi yake ndikofunikira kwambiri. Kusintha kwa zinthu zosiyanasiyana za pulagi ya spark kumasiyana. Mapulagi wamba a mkuwa-core amalimbikitsidwa kuti asinthidwe makilomita 2-30,000 aliwonse, pomwe mapulagi a iridium kapena platinum spark amatha kukulitsidwa mpaka makilomita 6-100,000. Tsatanetsatane wazinthu ziyenera kutumizidwa ku buku la malangizo a galimoto. Pakuyendetsa galimoto tsiku ndi tsiku, ndikofunikira kuyang'ana nthawi zonse momwe pulagi ya spark ilili, kuwona ngati elekitirodi yawonongeka, ngati pali mpweya woipa, komanso ngati thupi la ceramic lasweka. Nthawi yomweyo, samalani kusunga mafuta oyera, pewani kuyendetsa galimoto mtunda waufupi pafupipafupi, komanso pewani kuyamba nthawi yayitali nthawi yozizira. Makhalidwe abwino oyendetsera galimoto awa angathandize kuchepetsa kulephera kwa pulagi ya spark.
Pomaliza, ngakhale kuti cholumikizira cha spark ndi chaching'ono, ndi chofunikira kwambiri pakugwira ntchito bwino kwa injini. Kumvetsetsa ntchito yake, zolakwika zomwe zimachitika kawirikawiri, ndi njira zosamalira kungatithandize kuzindikira ndi kuthetsa mavuto pakapita nthawi, ndikusunga galimotoyo bwino.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
