Spark plugs: mitundu, kukula, kusiyana

Masiku ano, mitundu yambiri ya spark plugs imapangidwa. Zogulitsa za wopanga aliyense zimakhala ndi mawonekedwe ake. Tidalemba kale za ambiri aiwo patsamba lathu la Vodi.su pomwe tidaganizira zolemba zawo.

Zofunikira zazikulu zomwe mitundu ya makandulo imasiyanitsidwa:

• chiwerengero cha maelekitirodi - single kapena multi-electrode;
• zinthu zomwe chapakati elekitirodi amapangidwa ndi yttrium, tungsten, platinamu, iridium, palladium;
• nambala yowala - "ozizira" kapena "makandulo otentha.

Palinso kusiyana kwa mawonekedwe, mu kukula kwa kusiyana pakati pa mbali ndi electrode yapakati, muzojambula zazing'ono.

Kandulo yokhazikika

Uwu ndiye mtundu wamba komanso wofikirika kwambiri. Chida cha ntchito yake sichili chachikulu kwambiri, electrode imapangidwa ndi zitsulo zosagwira kutentha, choncho pakapita nthawi, zizindikiro za kukokoloka zimawonekera. Mwamwayi, mitengoyi ndi yotsika kwambiri, kotero kuti m'malo mwake musawononge ndalama zambiri.

M'malo mwake, makandulo onse opanga zapakhomo, mwachitsanzo, chomera cha Ufa, amatha kutengera zomwe zili - A11, A17DV, zomwe zimapita "ndalama". Ndikoyenera kuyang'ana mtundu wawo popanda kusiya kaundula wa ndalama, chifukwa kuchuluka kwa zolakwika kumatha kukhala kwakukulu. Komabe, ngati mutasankha zinthu zabwino komanso zapamwamba kwambiri, zimagwira ntchito popanda mavuto.

Musaiwalenso kuti moyo wautumiki umakhudzidwa kwambiri ndi momwe injiniyo ilili. Amatha kupanga madipoziti amitundu yosiyanasiyana, zomwe zikuwonetsa kugwiritsiridwa ntchito kosayenera kwa injini, mwachitsanzo, kupanga kusakaniza kowonda kapena kolemera kwamafuta amafuta.

Makandulo ambiri a electrode

Mu makandulo amenewa pali maelekitirodi angapo mbali - kuchokera awiri mpaka anayi, chifukwa chomwe moyo wautumiki ukuwonjezeka kwambiri.

Akatswiri adapeza lingaliro logwiritsa ntchito maelekitirodi angapo apansi, chifukwa ma elekitirodi amodzi amatentha kwambiri pakamagwira ntchito, zomwe zimachepetsa kwambiri moyo wake wautumiki. Ngati ma elekitirodi angapo akukhudzidwa, ndiye kuti amagwira ntchito ngati motsatana, motero, palibe kutenthedwa.

Ndizosangalatsanso kuti mainjiniya a kampani yamagalimoto yaku Sweden ya SAAB adaganiza zogwiritsa ntchito gawo lolunjika komanso lalitali pa pisitoni yokha m'malo mwa electrode yam'mbali. Ndiye kuti, kandulo imapezeka popanda electrode yam'mbali konse.

Ubwino wa yankho lotere ndilambiri:

• spark idzawoneka pa nthawi yoyenera pamene pisitoni ikuyandikira pamwamba pakufa;
• mafuta adzayaka pafupifupi popanda zotsalira;
• zosakaniza zowonda zimatha kugwiritsidwa ntchito;
• kupulumutsa kwakukulu ndi kuchepetsa mpweya woipa mumlengalenga.

Ngakhale izi zikadali zokonzekera zam'tsogolo, ma plug-electrode spark plugs amagwiritsidwa ntchito pa magalimoto othamanga, zomwe zimasonyeza khalidwe lawo. Zowona, ndipo mtengo wake ndi wapamwamba. Komabe, ma electrode amodzi akukonzedwa pang'onopang'ono, kotero ndizovuta kunena mosakayikira kuti ndi ati abwinoko.

Iridium ndi platinamu spark plugs

Iwo adawonekera koyamba mu 1997, adatulutsidwa ndi DENSO.

Zosiyanasiyana:

• chapakati elekitirodi zopangidwa iridium kapena platinamu ali makulidwe okha 0,4-0,7 mm;
• mbali elekitirodi analoza ndi profiled mwapadera.

Ubwino wawo waukulu ndi moyo wautali wautumiki, womwe ungafikire makilomita 200 zikwi kapena zaka 5-6 zoyendetsa galimoto.

Zowona, kuti athe kugwiritsa ntchito bwino zinthu zawo, m'pofunika kutsatira malangizo a wopanga:

• gwiritsani ntchito mafuta okhala ndi octane osatsika kuposa omwe afotokozedwa m'bukuli;
• pangani kukhazikitsa mosamalitsa molingana ndi malamulo - limbitsani kandulo mpaka mphindi inayake, ngati mwalakwitsa, ndiye kuti zotsatira zake zonse zidzakhazikika.

Kuti zikhale zosavuta kupotoza makandulo oterowo pamutu wa silinda, opanga amayika zoyimitsa zapadera zomwe zimawalepheretsa kumangirizidwa mopitilira muyeso.

Mfundo yokhayo yolakwika ndi yokwera mtengo. Ndikoyeneranso kudziwa kuti iridium ili ndi moyo wautali wautumiki kuposa platinamu, chifukwa chake mtengo wake ndi wapamwamba.

Monga lamulo, opanga magalimoto aku Japan amalimbikitsa kugwiritsa ntchito makandulo awa pamagalimoto awo. Izi zikugwira ntchito ku Toyota Camry ndi Suzuki Grand Vitara.

Makandulo okhala ndi electrode yapakati opangidwa ndi zinthu zina amakhalanso nthawi yayitali kuposa yokhazikika, koma sapezeka ambiri ogulitsa.
