Momwe mungayesere mayeso a compression

Mayeso a compression amapeza zovuta zambiri za injini. Ngati mayeso a psinjika ali pansipa zomwe wopanga akuwonetsa, izi zikuwonetsa vuto la injini yamkati.

M’kupita kwa nthawi, mwina mwaona kuti galimoto yanu sikuyenda bwino ngati mmene munali kugula poyamba. Pakhoza kukhala pali nkhokwe, kupunthwa, kapena moto wolakwika. Zitha kukhala zovuta nthawi zonse kapena nthawi zonse. Galimoto yanu ikayamba kugwira ntchito motere, anthu ambiri amaganiza zoyikonza. Kusintha ma spark plugs ndipo mwina mawaya oyatsira kapena nsapato kumatha kukonza vutoli - ngati ndiye vuto. Ngati sichoncho, ndiye kuti mukuwononga ndalama pazinthu zomwe simukuzifuna. Kudziwa momwe mungadziwire matenda owonjezera, monga kuyesa kukakamiza, kungakuthandizeni kuzindikira injini yanu molondola, zomwe zingakupulumutseni ndalama chifukwa simugula zinthu zomwe simungafune.

Gawo 1 la 2: Kodi mayeso oponderezedwa amayesa chiyani?

Mukazindikira mavuto ambiri a injini, ndikofunikira kuyesa mayeso opanikizika chifukwa izi zimakupatsani lingaliro la momwe injiniyo ilili. Pamene galimoto yanu imazungulira, pali zikwapu zinayi, kapena zoyenda zokwera ndi zotsika:

kumwa sitiroko: Ichi ndi sitiroko yoyamba yomwe imapezeka mu injini. Pa sitiroko iyi, pisitoni imayenda pansi mu silinda, kuilola kuti ijambule mosakaniza mpweya ndi mafuta. Kusakaniza kwa mpweya ndi mafuta ndi zomwe injini imafunikira kuti ipange mphamvu.

compression stroke: Ichi ndi sitiroko yachiwiri yomwe imapezeka mu injini. Pambuyo pokoka mpweya ndi mafuta panthawi yomwe mukudya, pisitoni tsopano imakankhidwiranso mu silinda, kukakamiza kusakaniza kwa mpweya ndi mafuta. Kusakaniza kumeneku kuyenera kukakamizidwa kuti injini ipange mphamvu iliyonse. Uku ndiye kutembenuka komwe mudzayesere mayeso a compression.

kusuntha kwamphamvu: Ichi ndi sitiroko yachitatu yomwe imapezeka mu injini. Ingoni ikangofika pamwamba pa kuponderezedwa, njira yoyatsira imapanga moto womwe umayatsa kusakaniza kwamafuta / mpweya. Kusakaniza kumeneku kukayaka, kuphulika kumachitika mu injini, komwe kumakankhira pisitoni pansi. Ngati panalibe kupanikizika kapena kupanikizika pang'ono panthawi yoponderezedwa, ndiye kuti kuyatsa uku sikungachitike molondola.

Kumasula sitiroko: Pakati pa sitiroko yachinayi ndi yomaliza, pisitoni tsopano imabwerera ku silinda ndikukakamiza mafuta onse ogwiritsidwa ntchito ndi mpweya kunja kwa injini kupyolera mu mpweya wotuluka kuti ayambenso ntchitoyo.

Ngakhale kuti zozungulira zonsezi ziyenera kukhala zogwira mtima, chofunikira kwambiri ndi kuzungulira kwa compression. Kuti silinda iyi ikhale ndi kuphulika kwabwino, kwamphamvu komanso koyendetsedwa bwino, kusakaniza kwamafuta a mpweya kuyenera kukhala pamphamvu yomwe injini idapangidwira. Ngati mayeso oponderezedwa akuwonetsa kuti kupanikizika kwamkati mu silinda ndikotsika kwambiri kuposa zomwe wopanga amapanga, ndiye kuti izi zikuwonetsa vuto la injini yamkati.

Gawo 2 la 2: Kuchita mayeso okakamiza

Zida zofunika:

• Compress tester
• Chida chojambulira pakompyuta (code reader)
• Ratchet yokhala ndi mitu yosiyanasiyana komanso zowonjezera
• Buku lokonzekera (mapepala kapena zamagetsi pazofunikira zamagalimoto)
• spark plug socket

Khwerero 1: Ikani galimoto yanu motetezeka kuti iwunikenso. Imani galimoto pamalo okwera, osasunthika ndikuyika mabuleki oimikapo magalimoto.

Khwerero 2: Tsegulani hood ndikulola injini kuziziritsa pang'ono.. Mukufuna kuyesa ndi injini yotentha pang'ono.

3: Pezani bokosi lalikulu la fuse pansi pa hood.. Nthawi zambiri amakhala bokosi lalikulu lapulasitiki lakuda.

Nthawi zina, idzakhalanso ndi zolemba zosonyeza chithunzi cha bokosilo.

4: Chotsani chivundikiro cha bokosi la fusesi. Kuti muchite izi, chotsani zingwe ndikuchotsa chivundikirocho.

Khwerero 5: Pezani cholumikizira chopopera mafuta ndikuchichotsa.. Izi zimachitika pogwira ndi kukoka molunjika kuchokera pabokosi la fusesi.

• Ntchito: Onani buku lokonzekera kapena chithunzi chomwe chili pa chivundikiro cha bokosi la fuse kuti mupeze cholumikizira cholondola cha pampu yamafuta.

Khwerero 6: Yambitsani injini ndikuyisiya kuti igwire ntchito mpaka itazimitsa. Izi zikutanthauza kuti injini yatha mafuta.

• KupewaZindikirani: Ngati simukuzimitsa makina amafuta, mafuta amayendabe mu silinda panthawi yoyeserera. Izi zitha kutsuka mafuta pamakoma a silinda, zomwe zingayambitse kuwerengedwa kolakwika komanso kuwonongeka kwa injini.

Khwerero 7: Chotsani zolumikizira zamagetsi pamiyendo yoyatsira.. Dinani latch ndi chala chanu ndikudula cholumikizira.

Khwerero 8: Masuleni zoyatsira. Pogwiritsa ntchito ratchet ndi socket yoyenera, chotsani mabawuti ang'onoang'ono omwe amatchinjiriza zotchingira zoyatsira ku ma valve.

Khwerero 9: Chotsani zingwe zoyatsira pozikoka molunjika kuchokera pachivundikiro cha valve..

Khwerero 10: Chotsani ma spark plugs. Pogwiritsa ntchito ratchet yokhala ndi socket yowonjezera ndi spark plug, chotsani ma spark plugs onse mu injini.

• Ntchito: Ngati ma spark plugs sanasinthidwe kwa nthawi yayitali, ndi nthawi yowasintha.

Khwerero 11: Ikani choyezera chopondera mu imodzi mwamadoko a spark plug.. Idutseni padzenje ndikumangitsani ndi dzanja mpaka itayima.

Khwerero 12: Yambani injini. Muyenera kulola kuti lizungulire kasanu.

Khwerero 13: Yang'anani kuwerenga kwa compression gauge ndikulemba..

Khwerero 14: Depressurize the compression gauge. Dinani valavu yotetezera kumbali ya geji.

Khwerero 15: Chotsani chopimitsira pa silinda iyi poyimasula ndi dzanja..

Gawo 16: Bwerezani masitepe 11-15 mpaka masilindala onse afufuzidwa.. Onetsetsani kuti zowerenga zalembedwa.

Khwerero 17: Ikani ma spark plugs okhala ndi ratchet ndi spark plug socket.. Alimbikitseni mpaka atalimba.

Khwerero 18: Ikani ma coil oyatsira mu injini.. Onetsetsani kuti mabowo awo okwera akugwirizana ndi mabowo omwe ali pachivundikiro cha valve.

Khwerero 19: Ikani mabawuti owonjezera kutentha pamanja.. Kenako amangitsani ndi ratchet ndi socket mpaka iwo snug.

Khwerero 20: Ikani zolumikizira zamagetsi pamiyendo yoyatsira.. Chitani izi powakankhira pamalo ake mpaka atadina, kusonyeza kuti atsekeredwa.

Khwerero 21: Ikani cholumikizira cha pampu yamafuta mu bokosi la fusesi pokanikizira m'mabowo omangika..

• Ntchito: Mukayika relay, onetsetsani kuti zikhomo zachitsulo pa relay zikugwirizana ndi bokosi la fuse ndipo mumakanikiza pang'onopang'ono mpaka mu bokosi la fuse.

Khwerero 22: Tembenuzani kiyi kumalo ogwirira ntchito ndikusiya pamenepo kwa masekondi 30.. Zimitsani kiyi ndikuyatsanso masekondi ena 30.

Bwerezani izi kanayi. Izi zidzayambitsa dongosolo lamafuta musanayambe injini.

Gawo 23: Yambitsani injini. Onetsetsani kuti imagwira ntchito mofananamo isanayambe kuyesa kukanikiza.

Mukamaliza kuyesa kukakamiza, mutha kufananiza zotsatira zanu ndi zomwe wopanga amalimbikitsa. Ngati kuponderezedwa kwanu kuli pansipa, mutha kukumana ndi limodzi mwamavuto awa:

Kukhomeredwa kwa silinda mutu gasket: Gasket yowombedwa ndi mutu imatha kuyambitsa kupsinjika pang'ono komanso zovuta zina za injini. Kuti mukonzenso gasket yamutu wa silinda yowombedwa, pamwamba pa injiniyo iyenera kulumikizidwa.

Mpando wa valve wowonongeka: Mpando wa vavu ukatha, valavu simatha kukhalanso ndikusindikiza bwino. Izi zidzamasula kuthamanga kwa compression. Izi zidzafuna kumangidwanso kapena kusintha mutu wa silinda.

Mphete za pistoni zovala: Ngati mphete za pistoni sizimasindikiza silinda, kuponderezedwa kudzakhala kochepa. Izi zikachitika, injiniyo iyenera kusinthidwa.

Zida ZophwanyikaA: Ngati muli ndi mng'alu mu chipika kapena mutu wa silinda, ndiye kuti izi zimabweretsa kupsinjika kochepa. Chiwalo chilichonse chomwe chang'ambika chiyenera kusinthidwa.

Ngakhale pali zifukwa zina zochepetsera kuponderezana, izi ndizofala kwambiri ndipo zimafuna kufufuza kwina. Ngati kupanikizika kocheperako kwapezeka, kuyesa kwa silinda kutayikira kuyenera kuchitidwa. Izi zidzakuthandizani kudziwa zomwe zikuchitika mkati mwa injini. Ngati mukuganiza kuti simungathe kudziyesa nokha, muyenera kupeza chithandizo kuchokera kwa makina ovomerezeka, monga "AvtoTachki", omwe angakuchitireni mayeso a compression.
