Valve giya ndechimwe chezvinhu zvakakosha zveinjini, kunyanya pakuona kubuda kwayo.Inoita basa rekugadzirisa mafambiro emafuta nemhepo inopinda nekubuda mumakamuri ekupisa einjini.Iro giya revharuvhu rine akati wandei akabatana zvinhu, zvinosanganisira camshaft, tappets, pushrods, rockers, uye mavharuvhu, ese anoshanda pamwechete kudzora kushanda kweinjini.
Imwe yakakosha yekutarisisa kana zvasvika kune giya revhavha huwandu hwekusimudza uye nguva yekuvhurwa kwevhavha.Kusimudza zvinoreva chinhambwe chinovhurwa nevharuvhu ukuwo kureba kuri kureba kwenguva iyo vharuvhu inoramba yakavhurika.Huwandu hwekusimudza uye hurefu hwenguva zvinotaridza kuti wakawanda sei mweya uye mafuta enjini anogona kutora mukati, izvo zvinozokanganisa kubuda kwayo.
Kune marudzi akasiyana-siyana emagiya evharuvhu anoshandiswa mumainjini, anosanganisira single-overhead cam (SOHC), dual-overhead cam (DOHC), uye pushrod.Imwe neimwe yeaya magiya evharuvhu ane mabhenefiti ayo uye anokanganisa, uye kunzwisisa mutsauko wawo kunogona kukubatsira iwe kusarudza iyo yakakodzera yeinjini yako yaunoda kushandisa.
SOHC valve giya, semuenzaniso, iri nyore asi inokwanisa kupa yakanakisa simba, torque, uye hupfumi hwemafuta.DOHC valve gear, kune rumwe rutivi, yakanyanya kuoma asi inogona kuvandudza kushanda kweinjini kuburikidza nemhepo iri nani yekupinda uye kupera, kunyanya pa RPM yakakwirira.Pushrod valve giya, inowanzobatanidzwa neinjini dzechikuru, kazhinji inodzika-inodzoreredza uye yakagadzirirwa torque yakawanda kupfuura kubuda kwebhiza.
Kana zvasvika pakugadzirisa injini inobuda uchishandisa giya revharuvhu, chinangwa chikuru ndechekuwana iyo yakanyanya kunaka kuyerera kwemhepo.Izvi zvinodaro nekuti mafambiro emhepo akakosha mukugadzira nzira yekupisa inoburitsa simba.Imwe nzira yekuwedzera kuyerera kwemhepo ndeyekushandisa yakakwira yekusimudza kana giya revhavha yenguva, ichibvumira injini kutora mamwe mafuta nemhepo.Nekudaro, nzira iyi ine painogumira, kuburitsa kwekupedzisira zvichienderana nezvinhu zvakaita sekutamisa injini, dhizaini yemusoro wecylinder, uye kugona kupisa.
Imwe nzira yekusimudzira kubuda kweinjini uchishandisa giya revharuvhu ndeyekugadzirisa nguva yevharuvhu kutora mukana weiyo injini yepamusoro torque uye simba rebhiza.Iwe unogona kuita izvi nekuyedza akasiyana cam profiles, ayo anoraira riini uye kuti mavharuvhu anovhura nekuvhara sei.Chinangwa pano ndechekuita kuti mavharuvhu avhurwe zvizere panguva yekupisa, zvichibvumira huwandu hunogona kuitika hwemafuta uye musanganiswa wemhepo kuburitsa simba rakawanda.
Mukupedzisa, giya revharuvhu chinhu chakakosha mune chero injini, uye kunzwisisa maitiro azvinoita kubuda kweinjini kunogona kukubatsira kukwirisa mashandiro einjini yako.Ita shuwa kuti unosarudza iro giya revharuvhu rakakodzera rekushandisa injini yako uye kuyedza nenguva yevharuvhu kuti uwane iyo inokwanisika kuyerera kwemhepo uye kubuda kwesimba.Chekupedzisira, gara uchifunga nezvekuchengetedza uye kuvimbika paunenge uchikwenenzvera kuita kweinjini yako uye bvunza nyanzvi kana usina chokwadi nezve kuita chero shanduko kugiya reinjini yako.
