Pulagi ya Spark ya Galimoto: Chenjezo Lofunika Kwambiri ndi Chenjezo Lolakwika la Mtima Wamphamvu wa Injini
Mu njira yolondola yogwiritsira ntchito injini ya galimoto, ngakhale kuti pulagi ya spark ndi yaying'ono, imatha kuonedwa ngati "key switch" ya mphamvu yotulutsa. Ntchito yake yayikulu ndikusintha magetsi amphamvu omwe amatumizidwa ndi choyatsira moto kukhala spark yamagetsi, kuyatsa bwino chisakanizo choyaka mu silinda, kuyendetsa pisitoni kuti igwire ntchito, ndikupereka mphamvu yopitilira ku injini. Njirayi ili ngati "spark yomwe ikuyatsa moto wamtchire", ndipo panthawi iliyonse yogwira ntchito ya injini, pulagi ya spark iyenera kumaliza kuyatsa moto pafupipafupi kangapo pamphindi. Ikalephera, injiniyo idzazimitsidwa.
Kuwonjezera pa ntchito yake yaikulu yoyatsira moto, pulagi ya spark imagwiranso ntchito zingapo zothandizira. Imatseka bwino dzenje la spark plug kuti isunge kukhazikika kwa kuthamanga kwa mpweya mu silinda, kupewa kutuluka kwa mpweya wotentha kwambiri komanso wopanikizika kwambiri, ndikuwonetsetsa kuti injini ikugwira ntchito bwino. Nthawi yomweyo, posintha nthawi yoyatsira moto ndi mphamvu ya spark, pulagi ya spark imatha kusintha malinga ndi mikhalidwe yosiyanasiyana ya injini: kukonza mafuta osawononga mphamvu pa liwiro lotsika, kuonetsetsa kuti mphamvu zotulutsa mphamvu zikuyenda bwino pa liwiro lokwera, monga "kapitawo woyatsira moto" wolondola. Choteteza chake cha ceramic chilinso ndi ntchito zoziziritsa komanso zoteteza kutentha, zomwe sizimangochotsa kutentha kwa electrode kuti iwonjezere moyo komanso zimaletsa kutentha kwambiri m'chipinda choyatsira moto, ndikupanga mikhalidwe yogwira ntchito bwino. Kuphatikiza apo, ndikofunikira kunena kuti mkhalidwe wa spark plug ukhoza kuwonetsa mwachindunji thanzi la injini. Zolakwika monga carbon deposits ndi kukokoloka kwa nthaka nthawi zambiri zimasonyeza zolakwika mu dongosolo lopangira mafuta kapena kuyaka kosakwanira, ndipo zitha kuonedwa ngati "chizindikiro cha thanzi" la injini.
Komabe, spark plug ndi imodzi mwa zinthu zomwe zimawonongeka mosavuta mu injini. Ikagwira ntchito kutentha kwambiri komanso kuthamanga kwambiri kwa nthawi yayitali, sizingapeweke kukumana ndi zolakwika zosiyanasiyana. Chofala kwambiri ndi kuwonongeka kwa ma electrode. Pamene mtunda ukuwonjezeka, kusiyana kwa ma electrode kudzakula pang'onopang'ono kuchokera pa ma millimeter 0.8-1.1 oyamba, zomwe zimapangitsa kuti mphamvu yoyatsira moto ichepe komanso kusayanika bwino kwa chisakanizocho, zomwe zingayambitse kutayika kwa mphamvu, kuchuluka kwa mafuta omwe amagwiritsidwa ntchito, ndi mavuto ena. Pamene kusiyanako kupitirira ma millimeter awiri, kungalephere kuyaka kwathunthu, zomwe zimayambitsa kusowa kwa silinda ya injini, komwe kumawonetsedwa ngati kugwedezeka kwakukulu pa liwiro lopanda ntchito, kuthamanga kwa liwiro, komanso nthawi zina, limodzi ndi ma alarm a kuwala kolakwika.
Ma carbon deposits ndi "mdani" wina wamkulu wa spark plug. Zonyansa zomwe zimapangidwa chifukwa cha kuyaka kosakwanira kwa mafuta zimamatira pamwamba pa spark plug, zomwe zimawonjezera kukana kwa elekitirodi, kufooketsa mphamvu ya spark, zomwe zimayambitsa zovuta poyambira kozizira, komanso liwiro losakhazikika. Ngati carbon deposits ndi yayikulu, ingayambitsenso kutuluka kwa spark plug, zomwe zimachepetsa kwambiri mphamvu ya kuyatsa. Kuphatikiza apo, kuwonongeka kwa insulation, kusagwirizana kwa mphamvu ya calorific, ndi kuyika kosayenera kungakhudzenso magwiridwe antchito a spark plug: ming'alu mu insulator imayambitsa kutuluka kwa spark, kuchuluka kwa mphamvu ya calorific kwambiri kapena kosakwanira kungayambitse kuyatsa kusanayambe kapena kuchedwa, ndipo mphamvu yoyikira yolakwika ingayambitse kutuluka kwa silinda, zomwe zimapangitsa kuti mphamvu yamagetsi itayike kwambiri.
Kulephera kwa mapulagi a spark sikovuta kuzindikira. Eni ake amatha kulandira machenjezo oyambirira kudzera mu mawonekedwe osazolowereka a magalimoto. Kuvuta kuyambira, makamaka kuyamba kosatheka kangapo m'malo ozizira, nthawi zambiri ndi chizindikiro cha kusiyana kwakukulu kwa ma electrode kapena kuchuluka kwa carbon deposits; kuyankha pang'onopang'ono kuthamangitsidwa, kuchuluka kwa mafuta komwe kumagwiritsidwa ntchito ndi 10%-15%, kungasonyeze mphamvu yoyatsira yosakwanira kapena kuchepa kwa mphamvu yoyatsira; pomwe kugwedezeka nthawi zonse pa liwiro lopanda ntchito ndi kugwedezeka panthawi yoyendetsa kungakhale zizindikiro za kulephera kuyatsa kwa silinda imodzi kapena zingapo. Zizindikiro izi zikapezeka, ndikofunikira kuyang'ana momwe spark plug ilili ndipo, ngati kuli kofunikira, kuisintha ndi chitsanzo choyenera.
Kuti awonjezere nthawi ya moyo wa spark plug, eni ake ayenera kutsatira njira yosinthira kutengera mawonekedwe a zinthu: ma spark plug wamba a nickel alloy akulimbikitsidwa kuti asinthidwe makilomita 2-3,000 aliwonse, ma spark plug a platinamu amatha kukulitsidwa mpaka makilomita 4-6,000, ndipo ma spark plug a iridium amatha kupitilira makilomita 8-10,000. Pakuyendetsa tsiku ndi tsiku, pewani kuyendetsa galimoto mothamanga kwambiri kwa nthawi yayitali, gwiritsani ntchito mafuta otsika, yeretsani nthawi zonse ma carbon deposits a injini, ndipo samalani kugwiritsa ntchito wrench yaukadaulo poyiyika kuti muwonetsetse kuti ikugwira ntchito bwino. Pokhapokha poika kufunika kokonza ndi kusintha spark plug, injini nthawi zonse imagwira ntchito bwino ndikupereka mphamvu yokhazikika komanso yamphamvu pagalimoto.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
