Ukhetho lobugcisa lwesitimela sevalve lumisela iimpawu eziqhelekileyo zoyilo lwe-injini kwaye lunempembelelo ebalulekileyo ekwakhiweni kwayo. Uninzi lwendlela yokuhambisa irhasi ye-injini yemoto isebenzisa iintlobo ezimbini zothumelo lwebhanti enamazinyo kunye netekhnoloji yokuhambisa ikhonkco. Ukukhethwa kweyona ndlela ifanelekileyo yokuhambisa ivalve kwisicelo esithile kufuneka isekwe kuvavanyo lwemigaqo ekujoliswe kuyo kwinqanaba lenkqubo ye-injini, kunye noqwalaselo olubanzi lwelahleko yokukhuhlana, amandla okudinwa, ukugcinwa, kunye notshintsho kwixesha levalve ubomi bonke benkonzo. , ukusebenza okuguquguqukayo, iimpawu ze-acoustic, umgangatho, indawo yokufakela kunye neendleko zokuvelisa kunye nezinye izinto.

Indlela yokusasazwa kwerhasi ichaphazela ngokuthe ngqo ukusetyenziswa kwamafutha enjini ngokulahleka kwayo kwe-friction, ngoko ke uyilo olusezantsi lokukhuhlana kwendlela yokuhambisa igesi luya lubaluleke ngakumbi nangakumbi. Xa kuthelekiswa netsheyini yasehlathini kunye netsheyina eliqengqelekayo, ityathanga elinamazinyo libonisa iziphene ezinkulu zokukhuhlana.
Xa ubude be-injini kufuneka bube bufutshane, i-chain drive ingcono kunokuqhuba ibhanti; uninzi lweenjini zepetroli kunye nezinye iinjini zedizili zisebenzisa i-hydraulic camshaft phase adjusters, kunye nechain drive kunye nebhanti emanzi zizikim zokuqhuba ukuhanjiswa kwegesi. Ukuqhuba ibhanti kunokufezekisa ukuchaneka kwexesha le-valve ephezulu kulo lonke ubomi benkonzo, eya kuba yinto ebaluleke kakhulu ekukhutshweni kwexesha elizayo kunye nokusetyenziswa kwamafutha. Ngenxa yoxinzelelo oluphezulu kunye noluphezulu lwenaliti, itorque yempompo yokutofa yamafutha ibaluleke kakhulu kwibhanti kunye netyathanga. Ubomi benkonzo bunesigqibo.
Ukuze ufezekise elona nqanaba lihle kakhulu le-NVH, ukungqubuzana kunye nokusebenza okuguquguqukayo, kuyimfuneko ukuyila ngononophelo kunye nokwandisa imilo yebhanti yebhanti, kodwa ayinanto yakwenza nohlobo lokudluliselwa kwevalve, ngoko kuya kuqhubeka kukho ukuxinana. phakathi kwebhanti yokuqhuba kunye nokhuphiswano lwe-chain drive.
