Sei vharafu ichikotama kana nguva yaputsika?
Iyo nzira yevhavha inoshanda seizvi: panguva iyo piston inosvika kumusoro kwakafa pakati, mavharuvhu ese ari mukamuri yekupisa akavharwa - imwe kumanikidza inogadzirwa mairi. Bhandi rakaputsika kunotungamirira kune chokwadi chokuti vharafu hauna nguva yekuvhara munguva isati yasvika yepiston. saka, musangano wavo unooneka - kudhumhana, izvo zvinonyatso kutungamirira kune chokwadi chokuti valve inokotama. Kare, kuitira kudzivirira dambudziko rakadaro, mavharuvhu akakosha akagadzirwa pamaICE ekare. Mamiriro akafanana anowanikwawo pachizvarwa chitsva ICE, asi anoitirwa chete kudzivirira deformation yemavharuvhu panguva yekushanda kweinjini yekupisa mukati uye kana pakaitika bhandi rekuputsika, havaponese zvachose.
Kubva pakuona kwemuviri, kubva panguva iyo bhanhire renguva rinoputika, camshafts pakarepo inomira, pasi pechiito chekudzoka zvitubu zvinoderedza makamera ayo. Panguva ino, crankshaft inertially inoenderera mberi nekutenderera kwayo (zvisinei nekuti giya raive rakabatikana kana kwete, marevolutions aive akaderera kana akakwira, iyo flywheel inoramba ichiitenderedza). Ndiko kuti, mapistoni anoramba achishanda, uye somugumisiro, anorova mavharuvhu akazaruka panguva iyoyo. Kashoma, asi zvinoitika kana mavharuvhu achikuvadza piston pachayo.
Zvikonzero zvebhandi renguva rakaputsika
- kupfeka kwebhandi sekudaro kana kunaka kwayo (magiya eshaft ane mipendero yakapinza kana mafuta kubva pazvisimbiso zvemafuta).
- crankshaft wedges.
- pombi wedges (inonyanya kuitika).
- akati wandei kana imwe camshaft wedges (somuenzaniso, nekuda kwekuora kweumwe wavo - zvisinei, pano mhedzisiro yacho yakati siyanei).
- iyo tensioning roller haina kuvharwa kana kuti ma roller ari wedged (pane kusunungura kana kuomesa bhanhire).
Injini dzemazuva ano, sezvo dziine simba kupfuura dzakadzitangira, dzine hupenyu hushoma. Kana tikafunga chikonzero, tichivimba nemavharuvhu, dambudziko iri rinoonekwa nekuda kwediki diki pakati pavo nepiston. Ndiko kuti, kana panguva iyo piston inosvika, valve iri ajar, ipapo inokotama pakarepo. Sezvo nokuda kwekudzvinyirira kukuru uye kudzvinyirira muzasi kwepiston hapana groove pasi pevhavha yehuku hunodiwa.
Ivhavha inokotama paI ICEs?
Pamichina ine 8-valve ICE, inokotama zvishoma, asi masero 16 ne20, angave ari peturu kana dhiziri, kubhenda kunoitika kazhinji. Ichokwadi, dzimwe nguva inogona kuva imwe kana kupfuura mavharuvhu, uye kana injini inopisa mukati ikashanda pasina basa, ipapo dambudziko richapfuura. Asi nyaya dzakadai ishoma, kazhinji, mhedzisiro yacho haidzoreki. Tafura ine runyorwa rwema ICE painokotama mavharuvhu emota dzese dzakakurumbira kana bhandi renguva radambuka.

Nzira yekuziva sei kana valve inokotama?
Kutarisa injini inopisa mukati kana mavharuvhu akakotama mushure mekuzorora kwenguva
Munyaya iyi, hapana kuongorora kwekuona kana nhamba dzakapihwa mumatafura e "valve bend" zvichakubatsira. Kunyange kana iwe uine ruzivo rwemaoko kubva kumugadziri pamusoro pekukuvadza kana bhanhire rakaputsika, hazvizivikanwi kuti yakavimbika sei.
Kana iwe uchida kutarisa mukana wekupeta mavharuvhu nepiston kana bhandi renguva raputika, unofanirwa kubvisa bhandi, isa piston yekutanga paTDC, shandura camshaft 720 madhigirii.
Kana zvinhu zvose zvakafamba zvakanaka uye haana kuzorora, unogona kuramba uchitarisa - enda kune yechipiri piston. Kana zvinhu zvese zvakanaka ipapo, ipapo bhandi rinogoneka rakaputsika harizotungamira kune zvakaipa mhedzisiro yeinjini yekupisa yemota yako.
Kuti udzivise dambudziko iri (kubhenda kwemavharuvhu pachiitiko chekuputsika), iwe unofanirwa kugara uchitarisa mamiriro uye kushushikana kwebhanhire renguva. Kana ruzha rusina kujaira ruchionekwa panguva yekushanda, iwe unofanirwa kuedza nekukurumidza kutsvaga chikonzero chekuitika kwayo, tarisa mamiriro eiyo rollers uye pombi.
Paunenge uchitenga motokari yakashandiswa, shandura bhandi renguva pakarepo, pasinei nokuti mutengesi anokuudza chii. Uye ipapo mubvunzo unokurumidza sekuti vharafu inokotama here kana yatsemuka Haunganetswi.
Bent valve zviratidzo
Apo bhanhire rakaputsika, zvino kungoshandura nguva yebhanhire, achitarisira kuti zvinhu zvose zvakaenda pasina migumisiro uye iwe unotanga injini, hazvina kukodzera. Kunyanya kana injini yemoto yemukati iri pane rondedzero yeavo iyo valve inokotama. Hongu, pane dzimwe nguva apo bend rakanga risiri rakakura uye mavharuvhu akati wandei haasati anyatsokodzera muchigaro chechigaro, ipapo unogona kushandura mutangi, asi kazhinji zviito zvakadaro zvichawedzerawo mamiriro acho ezvinhu. Sezvo nekukuvadza kudiki zvese zvichashanda uye kutenderera, zvisinei, injini yekupisa yemukati ichazununguka, uye mhedzisiro yacho inongowedzera.
Zvakanakisisa kana iwe ukabvisa "musoro" kuitira kuti utarise izvi nemaziso kana kuzadza parafini, zvisinei, pane nzira dzakawanda dzekutarisa kana valve yakakotama pasina kuparadzanisa injini inopisa yemukati.
Chiratidzo chikuru kana mavharuvhu akakotama - madiki kana zvachose hapana compression. Naizvozvo, iwe unofanirwa kuyera kudzvanywa mumasilinda. Asi, zviito zvakadaro zvakakosha kana crankshaft inogona kushandurwa uye hapana chinozorora chero kupi zvako. Saka chinhu chekutanga kuita kuisa bhandi idzva, nemaoko, nebhaudhi paHF, penya iyo yese gasi yekuparadzira michina matende mashoma (unofanirwa kusunungura makenduru panguva imwe chete).
Nzira yekutarisa kana valve yakakotama
kuitira kuti uone kana rimwe dzinde revharuvhu rakagonya, kutenderera kushanu chaiko kwekutendeuka nekiyi pane crankshaft bhaudhi zvichakwana. Kana tsvimbo dzakasimba, ipapo kutenderera kuchave kwakasununguka, kwakakotama - kunorema. Uye zvakare panofanira kunge paine zvinobatika 4 mapoinzi (pane imwe shanduko) yekupokana nekufamba kwepiston. Kana kushorwa kwakadaro kusingaonekwe, wobva wadzvanya makenduru kumashure, sunungura iwo rimwe nerimwe uye shandura crankshaft zvakare.
Nesimba remanyorero torsion, neimwe yemakenduru isipo, zviri nyore kunzwisisa kuti ndeipi humburumbira iyo valve (s) yakakotama. Zvisinei, iyi nzira haigoni kukubatsira nguva dzose kuziva kana valve yakakotama kana kwete.
Kana crankshaft ikatendeuka zvakasununguka, saka unogona tarisa ne compression gauge. Hakuna chombo chakadaro here? Means kuita pneumotest, uyezve, kutarisa kuoma kwemasilinda ndiyo nzira yakarurama kwazvo, iyo ichapa mhinduro pamusoro pekuti mahwendefa evharuvhu anokwana sei mumasadhi, pasina mimwe migumisiro paunenge uchifambisa neanotangira uye pasina kuisa bhanhire idzva.
Ndingatarisa sei kana valve yakakotama?
Nokuda kwepneumotest, haufaniri kudhonza motokari kuenda kuchiteshi chebasa, iwe pachako unogona kuona kana silinda yakaoma kana kuti kwete. Zviri nyore:
- tora chidimbu chehose maererano nehupamhi hwekenduru zvakanaka;
- bvisa kenduru;
- isa cylinder piston kumusoro yakafa centre (mavharuvhu akavharwa) rimwe nerimwe;
- isa hose zvakasimba mutsime;
- kuyedza nesimba rako rose kufuridza mukamuri rinopisa (mhepo inopfuura - yakakotama, haipfuure - "yakatsvaira").
Muedzo mumwe chete unogona kuitwa uchishandisa compressor (kunyangwe muchina mumwe). Chokwadi, uchafanira kupedza nguva yakati rebei, sezvaunoda kugadzirira. Dhonza iyo yepakati electrode mukenduru yekare, woisa pombi paceramic tip (kuigadzirisa zvakanaka nechirambi). Wobva wapomba kudzvanywa mucylinder (chero bedzi piston iri mairi iri paTDC).
Nekuridza mhere uye nekumanikidza pane geji yekumanikidza, zvichava pachena kana heti dzevharuvhu dzakagara mumachira kana kwete. Uyezve, zvichienderana nekuti mweya unoenda kupi, sarudza iyo inopinza kana yekubuda nayo yakabhenda. Kana iyo exhaust yakakotama, mhepo inopinda mune exhaust manifold (silencer). Kana mavharuvhu ekutora akakotama, zvino muchikamu chekutora.
