Gas kugovera mashandiro. Nei kudiwa?

Gas Kuparadzirwa mashandiro - chimwe chezvinhu zvinokosha zvikamu injini, kubva izvo zvakarurama mudzimu wayo waivako kunoenderana zvakananga. It anoshandira nenguva achizadza humburumbira yacho combustible musanganiswa kana mhepo (ari injector uye Diesel injini), uye nokuda zvaikosha kuti chiutsi magasi. The sezvamunoita zvinosanganisira nemotokari riini camshaft, zvingava bhandi, neketani kana rachulis pamusoro camshaft uye vharuvhu mashandiro. Mukupera muviri ukomba vari mavharuvhu uye rocker maoko. The yokupedzisira, akavapindurawo, wakaiswa kuti ekisero kuitira kuti munhu papfudzi kwaibva igadziridzwe sikuruu, uye wechipiri - iri vharuvhu hunde.

The camshaft ndiyo akabatana hwaakange machine psac eccentric (cam), maererano vharuvhu yokunyatsochengeta nguva pamakona. Danho nguva - ndiro nguva kuvhura nokuvhara vharuvhu. Izvi zvinoitika panguva apo humburumbira iri repamusoro kana nechepazasi akafa pfungwa. Ndezvipi kuzarura vharuvhu (Inlet kana nzira yokubudisa) inoenderana nokuti arohwa kunoitika neimwe humburumbira.

Somuenzaniso, kana ari pisitoni yava pasi akafa nepakati uye rinotanga compression sitiroko, vose mavharuvhu dzakavharika, kana chiutsi sitiroko ichi, kuti chiutsi vharuvhu yakazaruka. Hazvina musoro kufunga kuti wachi kutenderera rwekuita sitiroko mavharuvhu vose uyewo yakavharwa, uye kuzarura yaunodya Inlet. Gas Kuparadzirwa mashandiro ave mumwe kana miviri camshafts. Gas Kuparadzirwa mashandiro OHC - ndiwo wekutanga, wechipiri anonzi DOHC. Urongwa hwakadaro iri chete kushandiswa michina avo umo mumwe humburumbira vane 4 kana kupfuura mavharuvhu, akadai kubva 5 Audi.

Naizvozvo, gasi kuparadzirwa mashandiro DOHC injini unokubvumira unyatsobatsirwa kuita uye kuita kuti zvakatipoteredza noushamwari uye mari. Mumwe camshaft chakagadzirirwa kuvhura rimwe vharafu boka, kana kudya kana pedza.

Rakanga pakurukurwa gasi kugovera mashandiro SOHC. Rinewo 4 mavharuvhu por humburumbira, asi camshaft imwe chete rinoshandiswa kuvhura navo. nguva kwakadaro kwakapararira munyika 90s, asi nokukurumidza yakasiyiwa nokuda kwayo pasi zvibereko achienzaniswa DOHC.

Kuungana anotora kwakarurama pakaitika camshaft hama kuti crankshaft. It kunokwanisika nokushandisa kuti giya chitaridzi uchida chokubatanidza. Kana kushandisa bhandi nemotokari , kutanga akaisa pulleys zvichienderana chitaridzi, pashure izvo vari wakaiswa uye Worn nguva bhandi, iyo zvino akatambanudza makakatanwa chinotenderera.

Kuparadzirwa Gas mashandiro hakurevi anenge asina hanya, nayo ipfupi kuti nenguva kuchinja kwezvinhu vharuvhu Clearance. kukanganisa kwaro unotungamirira vawedzere kusakara nhengo uye haibvumiri injini yokukudziridza zvizere pakukwanisa kwayo. Uyezve, unogona akusungirire mavharuvhu, vanongogara vari hafu-rakavhurika chinzvimbo, uye kuvadza pistons, uye yaitsiva kunyange munhu anogona kurasikirwa zvinodhura zvikuru.
