Kodi pulagi ya spark ya galimoto ndi chiyani?
Pulagi ya spark ndiye gawo lalikulu la makina oyatsira injini ya petulo, omwe amapanga spark yamagetsi kudzera mu kutulutsa kwamphamvu kwamagetsi pakati pa ma electrode ndikuyatsa chisakanizo choyaka mu silinda kuti injini igwire ntchito.
Tanthauzo la plug ya Spark ndi ntchito zake zazikulu
Tanthauzo loyambira
Spark Plug (Spark Plug) ndi gawo lofunika kwambiri la makina oyatsira injini ya petulo, omwe amaikidwa pamwamba pa mutu wa silinda, omwe amachititsa kuti magetsi azilowa m'chipinda choyatsira moto, kudzera mu electrode gap discharge kuti apange ma spark amagetsi, kuyatsa chisakanizo chopanikizika mu silinda (mafuta ndi mpweya), motero amayendetsa kayendedwe ka pistoni kuti apange mphamvu. Chifukwa cha ntchito yake yayikulu, nthawi zambiri amatchedwa "ignition artifact" kapena "heart pacemaker" ya galimoto.
Momwe imagwirira ntchito
Mphamvu yamagetsi yapamwamba (nthawi zambiri ma volts 15,000 mpaka 30,000) imadutsa mu electrode yapakati ya pulagi ya spark, ndikuswa mpata wa mpweya pakati pa electrode ya mbali ndi njira ya ionization ndikutulutsa spark.
Kutentha kwa spark ndi kwakukulu kufika pa 2000 ~ 3000℃, komwe kumatha kuyatsa chisakanizocho nthawi yomweyo, zomwe zimapangitsa kuti kuyaka ndi kufutukuka zigwire ntchito.
Kapangidwe ndi mtundu wa pulagi ya spark
chigawo chachikulu
Kuphatikizapo nati ya waya, chotetezera, electrode yapakati, electrode ya mbali, chipolopolo chachitsulo, ndi zina zotero. Zipangizo za electrode (monga nickel alloy, platinamu, iridium, ndi zina zotero) zimakhudza mwachindunji kayendedwe ka magetsi ndi moyo wake.
Magulu Ofanana
Malinga ndi mtengo wa calorific: mitundu yozizira (yotentha kwambiri, yoyenera injini yamphamvu kwambiri) ndi yotentha (yotentha pang'ono, yoyenera injini ya low compression ratio).
ndi kapangidwe ka ma electrode : monga ndodo ya mbali imodzi, ndodo ya mbali zambiri (monga ndodo ya mbali zitatu kuti muwongolere kudalirika kwa kuyatsa).
ndi zinthu : pulagi ya nickel alloy spark (yotsika mtengo komanso yolimba), pulagi ya iridium gold spark (yogwira ntchito kwambiri komanso yogwiritsa ntchito mphamvu zochepa), ndi zina zotero.
Kufunika ndi magwiridwe antchito a ma spark plugs
Kugwira ntchito kwa injini
Kulondola nthawi yoyatsira moto kumakhudza mwachindunji mphamvu zomwe zimatulutsa komanso kugwiritsa ntchito bwino mafuta. Kuyatsa moto msanga kumabweretsa kuphulika, kuyatsa moto mochedwa sikokwanira.
Mapulagi a spark omwe akuwonongeka angayambitse vuto poyambitsa, kugwedezeka pang'ono, kapena kugwiritsa ntchito mafuta ambiri.
Kusintha kwa chilengedwe
Kuti zipirire kutentha kwambiri (madigiri zikwizikwi Celsius), kuthamanga kwambiri komanso dzimbiri la mankhwala, ma spark plug apamwamba amawongoleredwa ndi zipangizo zapadera monga ruthenium gold.
Malangizo osamalira ndi kusankha
Kusintha kwa kayendedwe kake: pulagi wamba wa nickel alloy spark plug pafupifupi 30,000 km, golide wa platinamu/iridium mpaka 6-100,000 km.
mfundo yosankhira : kufunika kogwirizana ndi kapangidwe ka injini, zofunikira zoyambirira, kupewa kusintha mwachisawawa kutentha kapena mtundu wa elekitirodi.
Kuti mudziwe zambiri za mtundu winawake (monga pulagi yagolide ya NGK ruthenium) kapena momwe galimotoyo imagwirira ntchito, mutha kuphatikiza mayeso amanja a galimoto kapena mayeso aukadaulo.
Zizindikiro zazikulu zochenjeza kuti galimoto ikufunika kusintha pulagi yake ya spark ndi monga kuvutika kuyatsa, kutayika kwa mphamvu, liwiro losakhazikika, kuchuluka kwa mafuta ogwiritsidwa ntchito molakwika, ndi magetsi olephera kugwira ntchito kwa injini. Zizindikiro izi nthawi zambiri zimakhala zokhudzana ndi kuchepa kwa mphamvu yoyatsira moto chifukwa cha kukalamba kwa pulagi ya spark kapena carbon deposits, ndipo ziyenera kuyang'aniridwa ndikusinthidwa pakapita nthawi kuti injini isawonongeke.
Zizindikiro zazikulu ndi maziko a chiweruzo
Chiyambi chovuta kapena chosakhazikika
Mukayamba kuzizira, ndikofunikira kuyatsa kangapo, kapena liwiro la injini limasintha kwambiri mukayamba. Izi zimachitika makamaka chifukwa cha kuwonongeka kwa electrode ya spark plug komwe kumabweretsa mphamvu yoyatsira yosakwanira, yomwe singathe kuyatsa mpweya wosakanikirana bwino.
Kusowa kwa mphamvu ndi kuthamanga
Mphamvu ya throttle imachepa poyendetsa, ndipo mphamvu imatsika kwambiri podutsa kapena kukwera. Mphamvu yoyatsira ya spark plug yosakwanira imabweretsa kuyaka kosakwanira ndikuchepetsa mphamvu ya injini.
Kugwedezeka kosazolowereka kapena kugwedezeka kosazolowereka panthawi yoyendetsa galimoto
Kugwedezeka kwa injini kumawonekera bwino galimoto ikayima, kapena kugwedezeka kwa thupi kukukulirakulira pa liwiro lotsika. Izi nthawi zambiri zimachitika chifukwa cha kuyika kwa carbon plug kapena kusiyana kwa ma electrode komwe kumachitika chifukwa cha kuyaka kosafanana, zomwe zimapangitsa kuti ntchito ya silinda isayende bwino.
Kugwiritsa ntchito mafuta kwawonjezeka kwambiri
Kuwonjezeka kwadzidzidzi kwa kugwiritsa ntchito mafuta popanda zifukwa zina zoonekeratu (monga kupanikizika kosakwanira kwa matayala) kungakhale kogwirizana ndi kusayatsa mafuta mokwanira chifukwa cha kuchepa kwa mphamvu ya kuyatsa kwa spark plug. Kuyatsa mafuta kwathunthu sikuti kungowononga chabe, komanso kumawonjezera vuto la kusonkhanitsa mpweya m'thupi.
Nyali ya injini yamavuto ikuyaka
Ngati galimoto yamakono yazindikira makina oyatsira olakwika, idzayambitsa kuwala kwa cholakwika kudzera mu makina owunikira a OBD, ndipo ndikofunikira kugwiritsa ntchito zida zaukadaulo kuti muwerenge khodi ya cholakwika kuti mutsimikizire pakapita nthawi.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
