Njira yabwino yosinthira ma spark plugs ndi iti: pa injini yozizira kapena yotentha

Ma electrode a Silver amadziwika ndi matenthedwe apamwamba kwambiri. Chifukwa cha izi, amakhala nthawi yayitali 2 kuposa zinthu wamba zoyatsira. malire awo chitetezo ndi zokwanira 30-40 zikwi makilomita kapena 2 zaka ntchito.

Ngati simukudziwa nthawi yosinthira ma spark plugs pa injini yozizira kapena yotentha, ndikosavuta kuwononga ulusi. M’tsogolomu, mwini galimotoyo angavutike kuchotsa mbali imene yawonongekayo.

Kusintha ma spark plugs: sinthani ma spark plugs pa injini yozizira kapena yotentha

Malingaliro otsutsana amalembedwa za momwe angakonzere bwino. Eni ake ambiri amagalimoto ndi amakaniki agalimoto amatsutsa kuti kuchotsa ndi kuyika zinthu zogwiritsidwa ntchito kuyenera kuchitidwa pagalimoto yokhazikika kuti zisawotchedwe ndikuthyola ulusi.

Pamalo ogwirira ntchito, makandulo nthawi zambiri amasinthidwa pa injini yofunda. Madalaivalawa akuti amisiriwa akufulumira kupereka dongosololi mwachangu popeza alibe mafani. Okonza magalimoto amafotokoza kuti ndikosavuta kuchotsa gawo lokhazikika pagalimoto yotenthetsera pang'ono. Ndipo ngati kukonzanso kukuchitika pa kutentha kwambiri kapena kutentha kwambiri, zimakhala zovuta kuchotsa gawolo. Zimawonjezeranso chiopsezo cha kuwonongeka kwa kapu ya waya pamene mukuyichotsa ku kandulo.

Kodi pali kusiyana kotani

M'malo mwake, mutha kusintha zida zoyatsira pa injini yotentha komanso yozizira, koma nthawi zina.

Momwe mungasinthire makandulo ndi manja anu

Kuti mumvetsetse momwe mungachitire izi molondola, muyenera kukumbukira malamulo ena afizikiki. Pali lingaliro la coefficient of thermal expansion. Imawonetsa kuchuluka kwa chinthu chomwe chidzakhala chokulirapo poyerekeza ndi kukula kwake chikatenthedwa ndi digirii 1.

Tsopano tiyenera kuganizira za zida za poyatsira pa kutentha kwa 20-100 ° C:

1. Kandulo yachitsulo yokhazikika imakhala ndi mphamvu yowonjezera yowonjezera ya 1,2 mm / (10m * 10K).
2. Izi chizindikiro cha ulusi wa aluminiyamu chitsime ndi 2,4 mm / (10m * 10K).

Izi zikutanthauza kuti ikatenthedwa, cholowera chamutu cha silinda chimakhala chachikulu nthawi 2 kuposa kandulo. Chifukwa chake, pamagalimoto ofunda, chogwiritsidwa ntchito chimakhala chosavuta kumasula, chifukwa kukanikiza kolowera kumachepa. Koma unsembe wa gawo latsopano ayenera kuchitidwa pa injini utakhazikika kuti kumangitsa pamodzi yamphamvu mutu ulusi.

Ngati gawolo liyikidwa "lotentha", ndiye kuti mutu wa silinda ukazizira bwino, udzawira. Zidzakhala pafupifupi zosatheka kuchotsa consumable chotero. Mwayi wokha ndikudzaza cholowera ndi mafuta a WD-40 ndikusiya gawo lophika kuti "lilowerere" kwa maola 6-7. Kenako yesani kumasula ndi "ratchet".

Pofuna kupewa zinthu zoterezi, kukonzanso kuyenera kuchitidwa pa kutentha kwa injini yoyenera, poganizira ma coefficients a kuwonjezereka kwa kutentha kwa zinthu zomwe zimagwiritsidwa ntchito ndi ulusi wa chitsime.

Momwe mungasinthire spark plugs molondola: pa injini yozizira kapena yotentha

M'kupita kwa nthawi, zinthu zomwe zimagwiritsidwa ntchito pagalimoto zimatha ndipo sizitha kugwira ntchito zake zonse. Nthawi iliyonse mukayambitsa injini, nsonga yachitsulo ya kandulo imafufutidwa. Pang'onopang'ono, izi zimabweretsa kuwonjezeka kwa spark kusiyana pakati pa ma electrode. Chifukwa chake, mavuto otsatirawa amabwera:

• kuwombera molakwika;
• kuyatsa kosakwanira kwa mafuta osakaniza;
• ma detonations mwachisawawa mu masilindala ndi exhaust system.

Chifukwa cha zochita izi, katundu pa masilindala amawonjezeka. Ndipo zotsalira zamafuta osawotchedwa zimalowa m'chothandizira ndikuwononga makoma ake.

Dalaivala akukumana ndi vuto loyambitsa galimoto, kuchuluka kwa mafuta ndi kutaya mphamvu ya injini.

Nthawi yobwezeretsa

Moyo wautumiki wa zinthu zoyatsira zimatengera izi:

• nsonga zakuthupi (nickel, siliva, platinamu, iridium);
• kuchuluka kwa maelekitirodi (ochuluka, amawotcha nthawi zambiri);
• kutsanulira mafuta ndi mafuta (kuchokera ku chinthu chosauka, kuvala kwa gawo kumatha kuwonjezeka mpaka 30%);
• injini (pa mayunitsi akale okhala ndi chiŵerengero chochepa cha kuponderezedwa, kuvala kumathamanga 2 nthawi).

Makandulo opangidwa ndi mkuwa ndi nickel (okhala ndi "petals" 1-4) amatha kuchoka pa 15 mpaka 30 makilomita zikwi. Popeza mtengo wawo ndi wochepa (pafupifupi 200-400 rubles), ndi bwino kusintha zogwiritsidwa ntchito ndi mafuta MOT iliyonse. Osachepera kamodzi pachaka.

Ma electrode a Silver amadziwika ndi matenthedwe apamwamba kwambiri. Chifukwa cha izi, amakhala nthawi yayitali 2 kuposa zinthu wamba zoyatsira. malire awo chitetezo ndi zokwanira 30-40 zikwi makilomita kapena 2 zaka ntchito.

Malangizo okutidwa ndi platinamu ndi iridium ndi odziyeretsa okha kuchokera ku ma depositi a kaboni ndikutsimikizira kuthetheka kosadukiza pakatentha kwambiri. Chifukwa cha ichi, iwo akhoza kugwira ntchito mosalephera mpaka makilomita zikwi 90 (mpaka zaka 5).

Ena eni magalimoto amakhulupirira kuti n'zotheka kuwonjezera moyo wa utumiki wa consumables ndi 1,5-2 zina. Kuti muchite izi, nthawi ndi nthawi chitani zotsatirazi:

• chotsani mwaye ndi dothi kunja kwa insulator;
• yeretsani ma depositi a kaboni powotcha nsonga mpaka 500 ° C;
• sinthani kusiyana kowonjezereka popinda ma elekitirodi am'mbali.

Njira iyi yothandizira dalaivala ngati alibe kandulo yopuma, ndipo galimoto yaima (mwachitsanzo, m'munda). Kotero inu mukhoza "kutsitsimutsa" galimoto ndi kupita ku siteshoni utumiki. Koma sikulimbikitsidwa kuchita nthawi zonse, chifukwa chiopsezo cha kuwonongeka kwa injini chikuwonjezeka.

Kutentha kofunikira

Pamene mukukonzekera, ndikofunika kuganizira coefficient of thermal expansion. Ngati spark plug imapangidwa ndi chitsulo ndipo chitsimecho chimapangidwa ndi aluminiyamu, ndiye kuti gawo lakale limachotsedwa pa injini yozizira. Ngati imamatira, galimotoyo imatha kutenthedwa kwa mphindi 3-4 mpaka 50 ° C. Izi zidzamasula kuponderezedwa kwa chitsime.

Kusintha kwa pulagi ya injini

Kugwetsa pa kutentha kwambiri kapena kotsika ndikoopsa. Opaleshoni yotereyi idzaphwanya kugwirizana kwa ulusi ndikuwononga kapu ya waya. Kuyika kwa gawo latsopano kumachitika mosamalitsa pagalimoto yokhazikika, kotero kukhudzanako kumayendera ndendende ulusi.

Zowonjezera zosankha

Kuti makandulo asalephere pasadakhale, m'pofunika kudzaza galimotoyo ndi mafuta apamwamba ndi mafuta okha.

Werenganinso: Momwe mungayikitsire mpope wowonjezera pa chitofu chagalimoto, chifukwa chake ndikofunikira

Palibe chifukwa choti mugule zinthu zomwe sizingagulitsidwe zamitundu yosadziwika (pali zabodza zambiri pakati pawo). Ndi bwino kukaonana ndi katswiri. Zokonda zimaperekedwa kuzinthu zamagetsi zambiri zokhala ndi iridium kapena platinamu sputtering.

Musanayambe kuchotsa gawo lakale, malo ogwirira ntchito ayenera kutsukidwa bwino ndi fumbi ndi dothi. Ndi bwino kupotoza chinthu chatsopano ndi manja anu popanda khama, ndiyeno kumangitsa ndi torque wrench ndi torque.

Ngati funso lidabuka: pa kutentha kotani komwe kuli koyenera kusintha kandulo, ndiye kuti zonse zimadalira siteji ya kukonza ndi mtundu wa zinthu za gawolo. Ngati chogwiritsidwa ntchito chakale chimapangidwa ndi chitsulo, chimachotsedwa pa injini yokhazikika kapena yotentha. Kuyika kwa zinthu zatsopano kumachitika mosamalitsa pa injini yozizira.
