Nzira yekuita sei compression test

Muedzo wekumanikidza unoongorora matambudziko mazhinji einjini. Kana iyo yekumanikidza bvunzo iri pazasi zvakatemwa nemugadziri, izvi zvinoratidza dambudziko remukati injini.

Nekufamba kwenguva, unogona kunge wakaona kuti mota yako haishande sezvayaiita pawakatanga kuitenga. Panogona kunge paine danga, kugumburwa, kana kutsva. Inogona kushanda yakaoma pasina basa kana nguva dzose. Kana mota yako ikatanga kushanda nenzira iyi, vanhu vazhinji vanofunga nezvekuigadzirisa. Kutsiva spark plugs uye pamwe waya dzekudzima kana bhutsu zvinogona kugadzirisa dambudziko - kana riri iro dambudziko. Kana zvisiri, saka unogona kunge uchipambadza mari pazvinhu zvausingade. Kuziva maitiro ekuwedzera diagnostics, senge compression test, inogona kukubatsira kuongorora injini yako nemazvo, izvo zvinogona kukuchengetedza mari nekuti hausi kuzotenga zvikamu zvaungasada.

Chikamu 1 che2: Ko bvunzo yekumanikidza inoyera chii?

Paunenge uchiongorora matambudziko mazhinji einjini, zvakakosha kuti uite bvunzo yekumanikidza sezvo izvi zvinokupa iwe pfungwa yemamiriro ese einjini. Sezvo mota yako ichitenderera, kune mana sitiroko, kana kumusoro nekudzika mafambiro:

kutora sitiroko: Iyi ndiyo sitiroko yekutanga inoitika muinjini. Munguva iyi sitiroko, piston inofamba ichidzika muhumburumbira, ichiibvumira kudhirowa musanganiswa wemhepo nemafuta. Uyu musanganiswa wemhepo nemafuta ndizvo zvinodiwa nejini kuti ikwanise kuburitsa simba.

compression sitiroko: Iyi ndiyo yechipiri sitiroko inoitika muinjini. Mushure mekukwevera mumhepo nemafuta panguva yekutora sitiroko, piston ikozvino inosundirwa kumashure muhumburumbira, ichimanikidza musanganiswa uyu wemhepo nemafuta. Musanganiswa uyu unofanirwa kudzvanywa kuti injini ibudise chero simba. Iyi ndiyo nguva yauchaita iyo compression test.

power stroke: Iyi ndiyo sitiroko yechitatu inoitika muinjini. Injini painongosvika pamusoro pekumanikidza sitiroko, iyo ignition system inogadzira spark inobatidza iyo yakamanikidzwa mafuta / mhepo musanganiswa. Kana musanganiswa uyu ukatungidzwa, kuputika kunoitika muinjini, uko kunosundira piston pasi. Dai pakanga pasina kudzvanywa kana kudzvanyirira kushoma panguva yekumanikidza, saka nzira yekubatidza yaisazoitika nemazvo.

Kusunungura sitiroko: Munguva yechina uye yekupedzisira sitiroko, piston ikozvino inodzokera kune cylinder uye inomanikidzira mafuta ose akashandiswa uye mhepo kubva mujini kuburikidza nekutsvaira kuitira kuti itangezve hurongwa zvakare.

Nepo ese aya matenderedzwa achifanira kushanda, chakanyanya kukosha ndeye compression kutenderera. Kuti iyi cylinder ive nekuputika kwakanaka, kune simba uye kudzorwa, musanganiswa wemhepo-mafuta unofanirwa kunge uri pakumanikidzwa iyo injini yakagadzirirwa. Kana iyo yekumanikidza bvunzo inoratidza kuti kumanikidza kwemukati muhumburumbira kwakadzikira zvakanyanya pane zvakatemwa nemugadziri, zvino izvi zvinoratidza dambudziko remukati injini.

Chikamu 2 che2: Kuita bvunzo yekumanikidza

Zvinhu zvinodiwa:

• Compression tester
• Computer scan tool (code reader)
• Ratchet ine misoro yakasiyana uye yekuwedzera
• Repair manual (bepa kana zvemagetsi kune zvakatemwa zvemotokari)
• spark plug socket

Danho 1: Isa motokari yako zvakachengeteka kuti iongororwe. Paka mota padanho, padanho uye isa bhureki rekupaka.

Danho rechipiri: Vhura hood uye rega injini itonhorere zvishoma.. Unoda kuyedza neinjini inodziya zvishoma.

Danho rechitatu: Tsvaga bhokisi guru refuse pasi pehodhi.. Kazhinji ibhokisi hombe repurasitiki dema.

Mune zvimwe zviitiko, ichavawo nechinyorwa chinoratidza dhayagiramu yebhokisi.

Danho rechina: Bvisa fuse bhokisi chivharo. Kuti uite izvi, bvisa marashi uye bvisa chivharo.

Nhanho yechishanu: Tsvaga pombi yemafuta relay uye uibvise.. Izvi zvinoitwa nekubata uye kudhonza zvakananga kubva mubhokisi refuse.

• Mabasa: Tarisa bhuku rekugadzirisa kana dhayagiramu riri pavhavha yebhokisi refuse kuti uwane chaiyo yepombi relay.

Danho rechitanhatu: Tanga injini uye rega imhanye kusvika yadzima. Izvi zvinoreva kuti injini yapera mafuta.

• Kudzivirira: Kana iwe ukasavhara iyo mafuta system, mafuta acharamba achiyerera mucylinder panguva yekumanikidza bvunzo. Izvi zvinogona kushambidza mafuta kubva pamadziro ecylinder, izvo zvinogona kutungamirira kune zvisiri izvo kuverenga uye kunyange kukanganisa injini.

Nhanho yechinomwe: Bvisa majoi emagetsi kubva pamakoiri ekudzima.. Dzvanya latch nemunwe wako uye bvisa chinongedzo.

Nhanho yechisere: Sunungura macoil ekudzima. Uchishandisa ratchet uye socket yakaenzana saizi, bvisa mabhaudhi madiki anochengetedza macoil ekupisa kune mavharuvhu anovhara.

Danho repfumbamwe: Bvisa macoil ekudzima nekuadhonza akananga kunze kwevhavhavhavhavhavha..

Nhanho 10: Bvisa spark plugs. Uchishandisa ratchet ine yekuwedzera uye spark plug socket, bvisa ese spark plugs kubva muinjini.

• Mabasa: Kana ma spark plugs asina kuchinjwa kwenguva yakati rebei, inguva yekuatsiva.

Nhanho 11: Isa yekumanikidza geji mune imwe ye spark plug ports.. Pfuura nepaburi uye woisimbisa neruoko kusvikira yamira.

Danho 12: Crank injini. Unofanira kuirega ichitenderera kanenge kashanu.

Nhanho 13: Tarisa kuverenga kwekumanikidza gauge uye nyora pasi..

Nhanho 14: Depressurize iyo yekumanikidza geji. Dzvanya vharafu yekuchengetedza padivi regeji.

Danho regumi neshanu: Bvisa geji yekumanikidza kubva muhumburumbira iyi nekuisunungura neruoko..

Nhanho 16: Dzokorora nhanho 11-15 kusvika masilinda ese atariswa.. Iva nechokwadi chokuti kuverenga kwakanyorwa.

Nhanho 17: Isa iyo spark plugs ine ratchet uye spark plug socket.. Zvisunge dzisimbe kusvika dzasimba.

Nhanho 18: Isai macoil ekubatidza kumashure muinjini.. Ita shuwa kuti maburi avo anokwirisa anoenderana nemakomba ari muvhavhavhavhavha.

Nhanho 19: Isa iyo inopisa inokwirisa mabhaudhi neruoko.. Zvadaro zvisimbise neratchet uye socket kusvikira zvanyatsoita.

Nhanho yechi20: Isai majoini emagetsi kumakoiri ekudzima.. Ita izvi nekuvasaidzira munzvimbo kusvika vabaya, vachiratidza kuti vakakiiwa panzvimbo.

Nhanho yechi21: Isai pombi yemafuta relay mubhokisi refuse nekuitsikirira kumashure mumakomba arikukwira..

• Mabasa: Pakuisa relay, ita shuwa kuti mapini esimbi pane relay anoenderana nebhokisi refuse uye kuti unoidzvanya zvinyoro nyoro kusvika mubhokisi refuse.

Danho rechi22: Shandura kiyi kunzvimbo yekushanda uye uisiye ipapo kwemaminitsi makumi matatu.. Dzima kiyi wobatidza zvakare kwemamwe masekonzi makumi matatu.

Dzokorora izvi kana. Izvi zvinotungamira iyo mafuta system isati yatanga injini.

Nhanho 23: tanga injini. Ita shuwa kuti inoshanda nenzira imwechete yayakaita isati yaitwa compression test.

Kana uchinge wapedza bvunzo yekumanikidza, unogona kuenzanisa mibairo yako kune izvo zvinokurudzirwa nemugadziri. Kana compression yako iri pazasi zvakatemwa, unogona kunge uri kusangana nerimwe rematambudziko anotevera:

Yakaroverwa cylinder head gasket: Iyo inoputika musoro gasket inogona kukonzera yakaderera compression uye akati wandei mamwe matambudziko einjini. Kuti ugadzirise inoputika cylinder head gasket, pamusoro peinjini inofanira kuparadzaniswa.

Chigaro chevharuvhu chakasakara: Kana chigaro chevharuvhu chapera, vharafu haigoni kugara uye kuvhara zvakanaka. Izvi zvinosunungura compression pressure. Izvi zvinoda kuvakwazve kana kutsiviwa kwehumburumbira musoro.

Zvindori zvepiston zvakapfekwa: Kana zvindori zvepiston zvikasasimbisa cylinder, iyo compression ichave yakaderera. Kana izvi zvikaitika, ipapo injini inofanira kugadziriswa.

Cracked ComponentsA: Kana iwe uine kutsemuka mubhuroko kana muhumburumbira musoro, zvino izvi zvinokonzeresa kudzvinyirira kwakaderera. Chero chikamu chakatsemuka chinofanira kutsiviwa.

Kunyangwe kune zvimwe zvikonzero zvekudzikira kwakaderera, izvi ndizvo zvakajairika uye zvinoda kumwe kuongororwa. Kana kudzvinyirirwa kwakaderera kuchionekwa, cylinder leak test inofanirwa kuitwa. Izvi zvichabatsira pakuongorora zviri kuitika mukati meinjini. Kana iwe usingafungi kuti iwe unogona kuita bvunzo iyi iwe pachako, iwe unofanirwa kutsvaga rubatsiro kubva kune akasimbiswa makanika, akadai kubva kuAvtoTachki, anogona kukuitira bvunzo yekumanikidza.
