Iqela lokudibanisa intonga liqulunqwe ngumzimba wentonga yokudibanisa, intonga yokudibanisa isigqubuthelo sentloko enkulu, intonga yokudibanisa umkhono wedolophana encinci, intonga yokudibanisa ihlathi elikhulu elithwele kunye nebholithi yokudibanisa (okanye i-screw), njl njl. amandla avela kwiphini yepiston, i-oscillation yayo kunye ne-inertia force reciprocating yeqela lepiston. Ubukhulu nolwalathiso lwala mandla luyatshintshwa ngamaxesha athile. Ngoko ke, intonga yokudibanisa iphantsi koxinzelelo, uxinzelelo kunye neminye imithwalo eguqukayo. Uqhagamshelwano kufuneka lube namandla okwaneleyo okudinwa kunye nokuqina kwesakhiwo. Amandla okudinwa akonelanga, ahlala ebangela ukuqhagamshelwa kwentonga okanye ukwaphuka kwebholithi yokudibanisa, aze avelise umonakalo omkhulu kumatshini. Ukuba ukuqina akwanelanga, kuya kubangela ukugoba komzimba wentonga kunye nokuguqulwa kwe-decircular yentloko enkulu yentonga yokudibanisa, ekhokelela ekusileni inxalenye yepiston, i-cylinder, i-bearing kunye ne-crank pin.
Umzimba wentonga yokudibanisa uqulunqwe ngamacandelo amathathu, kwaye inxalenye edibeneyo nepiston ibizwa ngokuba yintonga yokudibanisa intloko encinci; Indawo edityaniswe ne-crankshaft ibizwa ngokuba yintloko yentonga yokudibanisa, kwaye inxalenye yentonga edibanisa intloko encinci kunye nentloko enkulu ibizwa ngokuba yintonga yokudibanisa.
Ukuze kuncitshiswe ukunxiba phakathi kwentonga yokudibanisa kunye nepiston yepiston, i-bronze bushing enodonga oluncinci icinezelekile kumngxuma omncinci wentloko. I-drill okanye i-grooves yokusila kwiintloko ezincinci kunye namatyholo ukuvumela i-splash ukuba ingene kwindawo yokukhwela i-bush-piston.
Umzimba wentonga yokudibanisa yintonga ende, amandla emsebenzini nawo mkhulu, ukwenzela ukukhusela i-deformation yayo yokugoba, umzimba wentonga kufuneka ube nokuqina okwaneleyo. Ngesi sizathu, ibhodi yokudibanisa ye-injini yesithuthi ithatha icandelo eli-1. Icandelo elinemilo emi-1 linokunciphisa ubunzima phantsi kwemeko yokuqina okwaneleyo kunye namandla. Icandelo elibunjwe ngu-H lisetyenziselwa i-injini ephezulu yamandla. Ezinye ii-injini zisebenzisa intonga yokudibanisa enentloko encinci ukufaka ioli ukupholisa ipiston. Imingxuma mayigrunjwe ngobude bomzimba wentonga. Ukuze ugweme ukuxinzezeleka koxinzelelo, umzimba wentonga yokudibanisa kunye nentloko encinci kunye nentloko enkulu idibaniswe ngokuguqulwa okugudileyo kwe-arc enkulu.
Ukuze kuncitshiswe ukungcangcazela kwe-injini, umahluko omkhulu wentonga nganye yokudibanisa isilinda kufuneka ukhawulelwe kuluhlu oluncinci. Xa kuhlanganiswa injini kumzi-mveliso, igram ngokuqhelekileyo ithathwa njengeyunithi yokulinganisa ngokobunzima bentloko engezantsi yentonga yokudibanisa, kwaye iqela elifanayo lentonga yokudibanisa ikhethwa kwi-injini efanayo.
Kwi-injini yohlobo lwe-V, iisilinda ezihambelanayo kwikholamu ekhohlo nasekunene zabelana ngephini lokukranxa, kwaye intonga yokudibanisa ineentlobo ezintathu: intonga yokudibanisa ehambelanayo, intonga yokudibanisa ifolokhwe kunye nentonga engundoqo kunye neyokuncedisayo.
