Nzira yekugadzirisa sei?
Iyo gasi yekuparadzira michina inokonzera kuyerera kwemhepo-mafuta musanganiswa mumasilinda uye kubviswa kwezvinhu zvinopisa kubva kwavari.
Mamiriro ekushanda kwejini ndeyekuona kuyerera kwemafuta-mhepo musanganiswa mumasilinda uye kubviswa kwezvinhu zvinopisa kubva kwavari. Aya mabasa akakosha anoitwa nemuchina wekugovera.
Kune imwe neimwe humburumbira yeinjini kune zvikamu zvinosanganisira maviri mavharuvhu (inopinza uye exhaust), kazhinji matatu, mana kana mashanu, uye ayo actuators. Vanobvumira mavharuvhu kuti avhure kana piston iri panzvimbo chaiyo muhumburumbira. Dhizaini yeinjini uye nekumhanya kwayo inosarudza rudzi rwemashini inoshandiswa. Imwe yemaitiro ndeye 
kudiwa kwekudzikisa pesvedzero yeinertia yezvikamu zvinofamba pakururama kwekuvhura kwevharuvhu.
Mhando dzeTiming Systems
Rudzi rwekutanga rwemashini yaive yakaderera-vhavha gasi yekuparadzira michina. Yakatsiviwa nemhinduro yemazuva ano - iyo yepamusoro yevhavha nguva yenguva, umo mavharuvhu ese ari muhumburumbira musoro. Aya mavharuvhu anorembera anonongedza pasi. Kubatsira kwemhinduro iyi rusununguko rwekugadzirisa mavharuvhu ane madhayamita akakura zvakakwana. Izvo zvisingabatsiri nhamba huru yezvikamu uye kudiwa kwekuita kuti rigidity yakakwana yezvinhu zvepakati zvekufambisa simba. Iyi mhando yenguva yekumisikidza inowanzoshandiswa mumainjini emota dzinotakura vanhu.
Mavharuvhu mangani
Parizvino, silinda imwe neimwe ine maviri, matatu, mana kana mashanu mavharuvhu. Iyo yakawanda-vhavha system inopa yakakwira dhigirii yekuzadza silinda nemusanganiswa, 
inowedzera kutonhora kwevhavha plug, inoderedza kuvhurwa kwevharuvhu uye kunonoka kuvhara kwevhavha. Nokudaro, inonyanya kubatsira kune injini, uye inogara yakasimba kudarika maviri-vharuvhu.
OHV kana OHS?
Muvharuvhu repamusoro, matsimba evharuvhu anogona kufambiswa neshaft imwe iri mudzimba dzeinjini - iyi ndiyo OHV system kana mumusoro - iyo OHC system. Kana mavharuvhu achifambiswa nemashaft maviri akasiyana ari mumusoro, iyi inonzi DOHC system. Zvichienderana nedhizaini, mavharuvhu anobatiswa angave akananga kubva kune shaft cams kana kuburikidza nekumanikidza kuendesa levers pakati pecam uye hwaro hwevhavha stem. Chinhu chepakati ndicho chinopusher. Parizvino, matepi ekuchengetedza-emahara ane hydraulic valve clearance muripo anoshandiswa. Nhasi, OHC kana DOHC inowanzoshandiswa muEurope neJapan injini. Iyo OHV system yakatoshandiswa mumajini akati wandei, akadai seAmerican HEMI.
Torques dzakagadzirirwa kubva ku crankshaft kuenda kucamshaft dzinofambiswa kuburikidza nemagiya, cheni kana bhandi dhiraivha uchishandisa bhandi rine mazino. Iyo yekupedzisira mhinduro haidi lubrication, inopfeka inodzivirira uye haina kuwandisa mabhengi. Inonyanya kushandiswa mumotokari dzemazuva ano.
