Chii chinonzi mabhandi enguva?

Mabhandi enguva mabhande akakora akagadzirwa nerabha ane mazino akaomarara uye mitsetse mukati memukati mavo anovabatsira kukiyina nemacogwheels e crankshafts uye camshafts. Iwo anoshandiswa kupa simba uye kufambisa mabasa mumapombi emvura, pombi dzemafuta, uye majekiseni pombi, sezvinodiwa nekugadzirwa kweinjini. Anoshandiswa zvakanyanya muinjini dzinopisa mukati kuita kuti mavharuvhu einjini avhure uye avharwe zvine mutinhimira nenguva.

 

Ndeapi mashandisirwo emabhandi enguva?

Mabhandi enguva anonyatso shanda ane zvinotevera mashandisiro nemabasa:

Inotamba chikamu chakakosha mukubudirira kuita maitiro ekupisa nekunyatso kudzora piston nemavharuvhu.

Iyo inodzora kushanda kwevhavha nekubatanidza crankshaft uye camshaft pamwechete.

Inotarisira kuvhurwa kwakabatanidzwa uye kuvhara kwevhavha yejini.

Inobvisa kudiwa kwesimba rekunze rekushandisa kuvhura nekuvhara mavharuvhu nekushandisa simba remagetsi reinjini yekupisa.

Rimwe remabasa akakosha uye mashandisirwo emabhandi enguva nderekuti anodzora piston kubva pakurova zvakanyanya mavharuvhu.

Kunyangwe iri bhandi rimwechete kana mudziyo, inobatsira zvakanyanya mukushanda kweakawanda maficha seyepamusoro bhandi shaft sprocket, yakaderera bhandi shaft sprocket, camshaft bhandi dhiraivha giya, bhandi redhiraivha giya, bhandi bhandi tensioner roller, uye nguva bhandi tensioner roller.

 

Ndeipi nzira yekushanda yemabhandi enguva?

Mabhandi enguva anowiriranisa basa rekuvhara-kuvhura uye nguva dze crankshaft, camshaft, uye exhaust valve. Inobatsira mukutora mafuta nemhepo inopinda mujini yekupisa, pamwe nekudzora vheji yekuburitsa kuti utsi kana kupera kupukunyuka. Bhandi rinochengetedza injini yakarongeka uye inochengetedza kukwanisa kwayo uye kubudirira.

 

Nguva yekutsiva bhandi renguva?

Kuitika kwezviratidzo izvi kunoratidza kukosha kwekuchinja bhandi rekare uye rakasakara uye kuritsiva nebhandi idzva renguva:

Yakaderedzwa injini simba

Kupisa kweinjini

Kuitika kwekuzunguzika kana kuzunguzika muinjini

Kunetsa kutanga muchina kana mota

Kukwesha kana kuridza mhere mhere inobva pabhandi

Kurira kunorira kubva muinjini

Mafuta ari kubuda kubva muinjini

Kusagadzikana mukushanda kwechiedza cheinjini
