Masewerawa ndi ofunika kandulo

M'mainjini omwe amagwiritsidwa ntchito pano, moyo wa spark plug umakhala pafupifupi 30-45 zikwi. km, koma pali nthawi zina pomwe kusinthidwa koyambirira kumafunika.

Injini ikakhala "chabwino", siimayamba bwino, imayenda movutikira, imatsika, kapena imawonjezera mafuta, ndiye chifukwa chake madalaivala ambiri amatembenukira kwa makanika.

Ndi zamagetsi zomwe zimagwiritsidwa ntchito m'zinthu zamakono zoyatsira moto, ichi ndi chinthu choyenera kuchita, chifukwa n'zovuta kudziwa chifukwa chake nokha, ngakhale kuti chimodzi mwa zifukwa zomwe zingatheke chikhoza kukhala cholakwika cha spark plug.

M'ma injini omwe akugwiritsidwa ntchito pano, moyo wa pulagi wa spark plug pafupifupi pafupifupi 20 miliyoni wozungulira, womwe ukhoza kukhala pafupifupi 30-45 zikwi. makilomita adayenda, koma pamakhala zochitika zomwe m'malo mwake zimafunikira. Izi zimagwira ntchito, mwachitsanzo, ku injini za gasi (LPG / CNG), kumene izi zimakhala chifukwa cha zovuta zogwirira ntchito (makamaka kuyaka kwapang'onopang'ono ndi kutentha kwakukulu). Ubwino wamafuta omwe amagwiritsidwa ntchito ndi chinthu choyipa chomwe chimakhudza mkhalidwe wa kandulo.

Mufuna chiyani kuti mukagule kandulo?

Ntchito yaikulu ya spark plug ndikupanga magetsi okhazikika komanso okwanira pakati pa ma electrode, komanso kuchotsa kutentha kuti zikhale pansi pa malire a auto-ignition of the mafuta osakaniza, i.e. pafupifupi 900 ° C. 

Pachifukwa ichi, kusankha mtundu woyenera wa spark plug pamtundu uliwonse wa injini ndikofunikira kwambiri. Zimanenedwa ndi wopanga injini, akulimbikitsa kugwiritsa ntchito makandulo apangidwe kake, mtengo wa calorific woyembekezeredwa ndi moyo wawo wautumiki.

Chifukwa chake palibe plug spark plug yoyenera mtundu uliwonse wa injini! M'malo mwa "zozizwitsa" zilizonse, kuphatikizapo makandulo a electrode ambiri, sizikuyenda bwino. zimakhudza kwambiri magawo a injini, koma kutalikitsa moyo ndi kudalirika kwa pulagi ya spark.

Izi zikugwiranso ntchito kwa ma spark plugs omwe maelekitirodi amapangidwa ndi ma aloyi okwera mtengo (yttrium, platinamu), kugwiritsa ntchito komwe kumalimbikitsidwa komwe kuli koyenera (mwachitsanzo, pankhani ya injini zamagesi kapena magawo amagetsi agalimoto zamagalimoto).

Kuzizira, kutentha, kutentha

Malingana ndi kutentha kwazomwe zimatchedwa Pali mitundu itatu ikuluikulu ya spark plugs molingana ndi "thermal coefficient", yomwe imasonyeza kuthekera koyendetsa ndi kutaya kutentha.

"Hot" high calorific value, yodziwika ndi insulator pamwamba pamwamba yomwe imatenga kutentha kwambiri, "yapakati" kutentha mapulagi okhala ndi zosungunulira zochepa, kotero kuti kutentha kwakukulu kumatayidwa kuposa pulagi "yotentha" ku zigawo za injini, ndi mapulagi "ozizira" ”, kutentha kochepa kwambiri.

Mapulagi "otentha" amagwiritsidwa ntchito m'mainjini osapanikizika kwambiri, pomwe mapulagi "ozizira" amagwiritsidwa ntchito m'mainjini ovuta kwambiri.

Kuyeretsa kapena kusintha?

Ngati mukutsuka, gwiritsani ntchito maelekitirodi okha ngati pali mwaye pang'ono, pogwiritsa ntchito burashi yofewa kwambiri. Sandpaper kapena sandblasting ndi chinthu chakale. Ndi kupezeka kwaposachedwa komanso mitengo yotsika, ndikwabwino kusintha mapulagi a spark ndi atsopano, kutsatira malingaliro a wopanga injini.

Kodi tingathe kuchita tokha? Tsoka ilo, chifukwa cha kuyika kwa makandulo, ntchito yosavutayi ikupitirira zosatheka popanda zida zapadera. Posunga eni magalimoto akale amatha kuchita izi mosamala komanso mosamala.

Imodzi mwa malamulo ofunikira ndikuyimitsa kandulo ndi zala zanu mpaka kukana kumveka, ndiyeno kumangitsa ndi wrench. Izi zidzateteza kuwonongeka kwa ulusi wa socket.

spark plug yoyikidwa moyipa nthawi zambiri imabweretsa kukonzanso kwamutu kokwera mtengo.

Mukasintha ma spark plugs, ndiyeneranso kuyang'ana mosamala mawaya oyaka ndi maulumikizidwe awo, ndipo ngati ilipo, yang'anani chipangizo choyatsira, chomwe chimadalira machitidwe onse.
