Iqembu lenduku yokuxhuma lakhiwe ngomzimba wenduku yokuxhuma, induku yokuxhuma isembozo sekhanda elikhulu, induku yokuxhuma inhloko encane, induku yokuxhuma isihlahla esikhulu esithwala ikhanda kanye nebholiti lenduku yokuxhuma (noma isikulufu), njll. Iqembu lenduku yokuxhuma libhekene namandla kagesi avela kuphini lepiston, ukushukuma kwalo kanye namandla okubuyela emuva eqembu lepiston. Ubukhulu kanye nesiqondiso sala mandla kuyashintshwa njalo. Ngakho-ke, induku yokuxhuma ibhekene nokucindezelwa, ukucindezelwa kanye neminye imithwalo eshintshanayo. Ukuxhumana kumele kube namandla anele okukhathala kanye nokuqina kwesakhiwo. Amandla okukhathala awanele, ngokuvamile abangela ukuphuka komzimba wenduku yokuxhuma noma ukuphuka kwebholiti lenduku yokuxhuma, bese kudala umonakalo omkhulu womshini wonke. Uma ukuqina kunganele, kuzobangela ukugoba komzimba wenduku kanye nokuguquguquka kwe-decircular kwekhanda elikhulu lenduku yokuxhuma, okuholela ekugayweni okuyingxenye kwepiston, isilinda, ibhereyi kanye nephini le-crank.
Umzimba wenduku yokuxhuma wakhiwe izingxenye ezintathu, kanti ingxenye exhunywe nephini le-piston ibizwa ngokuthi induku yokuxhuma inhloko encane; Ingxenye exhunywe ne-crankshaft ibizwa ngokuthi inhloko yenduku yokuxhuma, kanti ingxenye yenduku exhumanisa ikhanda elincane nekhanda elikhulu ibizwa ngokuthi induku yokuxhuma.
Ukuze kuncishiswe ukuguguleka phakathi kwenduku yokuxhumanisa kanye nephini le-piston, i-bronze bushing enodonga oluncane icindezelwa emgodini omncane wekhanda. Ibhoboza noma i-mill grooves ibe ngamakhanda amancane kanye nama-bushings ukuze kuvunyelwe ukuchaphaza ukuthi kungene ebusweni bokuhlangana kwephini le-bush-piston.
Umzimba wenduku yokuxhuma uyinduku ende, amandla asebenzayo nawo makhulu, ukuze kuvinjelwe ukuguquguquka kwayo kokugoba, umzimba wenduku kumele ube nokuqina okwanele. Ngenxa yalesi sizathu, umzimba wenduku yokuxhuma wenjini yemoto usebenzisa kakhulu ingxenye enobume obu-1. Ingxenye enobume obu-1 inganciphisa ubunzima ngaphansi kwesimo sokuqina namandla anele. Ingxenye enobume obu-H isetshenziselwa injini enamandla aphezulu. Ezinye izinjini zisebenzisa induku yokuxhuma enekhanda elincane ukufaka uwoyela ukuze kuphole i-piston. Izimbobo kumele zibholwe ngobude emzimbeni wenduku. Ukuze kugwenywe ukugxilisa ingqondo, umzimba wenduku yokuxhuma kanye nekhanda elincane kanye nekhanda elikhulu kuxhunywe ngokushintsha okubushelelezi kwe-arc enkulu.
Ukuze kuncishiswe ukudlidliza kwenjini, umehluko wesisindo senduku yokuxhuma yesilinda ngayinye kumele ulinganiselwe ebangeni elincane kakhulu. Lapho kuhlanganiswa injini efektri, igremu ngokuvamile ithathwa njengeyunithi yokulinganisa ngokwesisindo sekhanda elingezansi lenduku yokuxhuma, futhi iqembu elifanayo lenduku yokuxhuma likhethwa enjinini efanayo.
Enjinini yohlobo lwe-V, amasilinda ahambisanayo kumakholomu angakwesobunxele nakwesokudla abelana ngephini le-crank, kanti induku yokuxhuma inezinhlobo ezintathu: induku yokuxhuma ehambisanayo, induku yokuxhuma yefoloko kanye nenduku yokuxhuma eyinhloko nesizayo.
