Plug yeSpark yeMota: Muchengeti Mukuru uye Yambiro Yekukanganisa kweMwoyo weSimba reInjini
Muhurongwa hwekushanda chaihwo hweinjini yemota, kunyangwe chivharo chemoto chiri chidiki, chinogona kuonekwa se "key switch" yekuburitsa simba. Basa rayo guru nderekushandura magetsi ane simba guru anotumirwa ne ignition coil kuita chivharo chemagetsi, zvichinyatsobatidza musanganiswa unobvira uri mu cylinder, zvichifambisa piston kuti iite basa, uye zvichipa simba risingaperi kuinjini. Maitiro aya akafanana ne "chivharo chemoto chinobatidza moto wesango", uye panguva yega yega yekushanda kweinjini, chivharo chemoto chinofanira kupedzisa kubatidza nekakawanda kanoverengeka paminiti. Kana chakundikana, injini ichaoma.
Kuwedzera pabasa rayo guru rekubatidza, chivharo chespark chinoitawo mabasa akawanda ekubatsira. Chinovhara gomba respark plug zvakasimba kuti chichengetedze kugadzikana kwesimba riri mu cylinder, kudzivirira kubuda kwegasi rinopisa zvakanyanya uye rinomanikidzwa zvakanyanya, uye kuona kuti injini inoshanda zvakanaka. Panguva imwe chete, nekugadzirisa nguva yekubatidza uye simba respark, chivharo chespark chinogona kuchinjika nemamiriro akasiyana einjini: kugadzirisa kushandiswa kwemafuta nekukurumidza kwakaderera, kuve nechokwadi chekuti simba rinobuda nesimba nekukurumidza kwakakwirira, senge "mutungamiriri wekupisa" chaiwo. Chivharo chayo checeramic chinewo mabasa ekutonhodza uye ekudzivirira kupisa, ayo asingangogone kudzima kupisa kwe electrode kuti awedzere hupenyu asiwo kudzivirira kupisa kwakanyanya mukamuri yekubatidza, zvichigadzira mamiriro ekushanda kwakasimba. Uyezve, zvakakosha kutaura kuti mamiriro espark plug anogona kuratidza zvakananga hutano hweinjini. Zvisina kujairika zvakaita se carbon deposits uye erosion zvinowanzoratidza zvikanganiso mu system yekuisa mafuta kana kupisa kusina kukwana, uye zvinogona kuonekwa se "chiratidzo chehutano" cheinjini.
Zvisinei, spark plug ndeimwe yezvinhu zvinonyanya kupfekwa muinjini. Ichishanda pasi pekupisa kwakanyanya uye kumanikidzwa kwakanyanya kwenguva yakareba, hazvidzivisiki kusangana nezvikanganiso zvakasiyana-siyana. Chinonyanya kuitika ndechekusakara kwema electrode. Sezvo mileage ichiwedzera, electrode gap inokura zvishoma nezvishoma kubva pa 0.8-1.1 millimeters yekutanga, zvichikonzera simba rekupisa risina simba uye kusakwana kwekupisa kwemusanganiswa, izvo zvinogona kutungamira mukurasikirwa kwesimba, kuwedzera kwekushandiswa kwemafuta, nezvimwe zvinetso. Kana spark plug ikadarika 2 millimeters, inogona kutotadza kubatidza zvachose, zvichikonzera kushomeka kwemasilinda einjini, zvichiratidzwa nekuzunguzika kwakanyanya pakumhanya kusina basa, kumhanyisa kumhanya, uye mune zviitiko zvakakomba, pamwe chete nemaalamu emwenje yekutadza.
Makabhoni anodonhedzwa mumhepo ndeimwe "muvengi" mukuru we spark plug. Kusachena kunokonzerwa nekupiswa kwemafuta kusina kukwana kunonamatira pamusoro pe spark plug, zvichiwedzera kuramba kwe electrode, zvichideredza simba re spark, zvichikonzera matambudziko pakutanga kwechando, kumhanya kusina kugadzikana. Kana scarbogen inodonhedzwa zvakanyanya, inogona kutokonzera kubuda kwe spark plug, zvichideredza zvakanyanya kushanda kwekupisa. Pamusoro pezvo, kukuvara kwe insulation, kusaenderana kwe calorific value, uye kusaiswa zvakanaka zvinogonawo kukanganisa mashandiro e spark plug: kuputika mu insulator kunokonzera kubuda kwe spark, kuwanda kwe calorific value zvakanyanya kana kusakwana kunokonzera kupiswa kusati kwatanga kana kunonoka, uye torque isina kunaka yekuiswa inogona kukonzera kubuda kwe cylinder, zvichiwedzera kurasikirwa nesimba.
Kukundikana kwemaplagi espark hakuna kuoma kuona. Varidzi vanogona kugamuchira yambiro dzekutanga kuburikidza nezviratidzo zvisina kujairika zvemotokari. Kuoma kwekutanga, kunyanya kutanga kwakundikana kakawanda munzvimbo dzinotonhora, kazhinji chiratidzo chekusashanda zvakanaka kwemaelectrode kana carbon deposits yakawandisa; kunonoka kupindura kumhanya, kushandiswa kwemafuta kwakawedzera zvisinganzwisisike ne10%-15%, zvinogona kuratidza simba rekupisa risina kukwana kana kudzikira kwekushanda kwekupisa; nepo kuzununguka nguva dzose nekumhanya kusingashande uye kuzununguka panguva yekutyaira zvinogona kunge zviri zviratidzo zvekutadza kushanda zvakanaka kwemasilinda rimwe chete kana akawanda. Kana zviratidzo izvi zvaonekwa, zvakakosha kutarisa mamiriro espark plug uye, kana zvichidikanwa, kuitsiva nemodhi yakakodzera.
Kuti vawedzere hupenyu hwe spark plug, varidzi vanofanira kutevedzera kutenderera kwekutsiva zvichienderana nehunhu hwezvinhu: ma spark plugs akajairwa e nickel alloy anokurudzirwa kutsiviwa makiromita ese 2-3,000, platinum spark plugs anogona kuwedzerwa kusvika makiromita 4-6,000, uye iridium spark plugs anogona kugara makiromita 8-10,000. Mukutyaira kwezuva nezuva, dzivisa kutyaira kwenguva refu usingamhanye zvakanyanya, shandisa mafuta asina kunaka, chenesa injini nguva dzose, uye teerera kushandisa torque wrench yehunyanzvi panguva yekuisa kuti uve nechokwadi chekuti inoshanda zvakanaka. Injini inogona kushanda zvakanaka chete nekuchengetedza nekutsiva spark plug.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
