Iqembu lenduku yokuxhuma lakhiwe ngomzimba wenduku exhumayo, induku yokuxhuma ikhava yekhanda elikhulu, induku yokuxhuma umkhono wenhloko yesigodi, induku yokuxhuma isihlahla esithwele ikhanda kanye nebhawodi yenduku yokuxhuma (noma isikulufu), njll. Iqembu lezinduku ezixhumayo lingaphansi kwegesi. amandla asuka kuphinikhodi ye-piston, i-oscillation yayo kanye namandla aphindaphindayo e-inetia eqembu le-piston.Ubukhulu nokuqondisa kwalawa mandla kuyashintshwa ngezikhathi ezithile.Ngakho-ke, induku yokuxhuma ingaphansi kokucindezelwa, ukungezwani neminye imithwalo eshintshanayo.Ukuxhuma kufanele kube namandla okwanele okukhathala kanye nokuqina kwesakhiwo.Amandla okukhathala awanele, ngokuvamile abangela ukuxhuma umzimba wenduku noma ukuphuka kwebhawodi yenduku yokuxhuma, bese kukhiqiza wonke umonakalo womshini engozini enkulu.Uma ukuqina kunganele, kuzodala ukugoba komzimba wenduku kanye nokuguqulwa kwe-decircular kwekhanda elikhulu lenduku yokuxhuma, okuholela ekugayeni ingxenye yepiston, isilinda, i-bearing kanye ne-crank pin.
Umzimba wenduku yokuxhuma wakhiwe izingxenye ezintathu, futhi ingxenye exhunywe nephinikhodi ye-piston ibizwa ngokuthi induku yokuxhuma ikhanda elincane;Ingxenye exhunywe ne-crankshaft ibizwa ngokuthi i-connecting rod head, kanti ingxenye yenduku ehlanganisa ikhanda elincane nekhanda elikhulu ibizwa ngokuthi induku yokuxhuma.
Ukuze unciphise ukuguga phakathi kwenduku yokuxhuma nephinikhodi, i-bronze bushing enezindonga ezincane icindezelwa emgodini omncane wekhanda.Gcoba noma ugaywe ube amakhanda amancane nezihlahlana ukuze uvumele ukuchaphaza kungene endaweni yokukhwelana yephini le-bush-piston.
Umzimba wenduku yokuxhuma uyinduku ende, amandla emsebenzini nawo makhulu, ukuze avimbele ukuguquguquka kwawo okugoba, umzimba wenduku kufanele ube nokuqina okwanele.Ngalesi sizathu, indikimba yenduku yokuxhuma yenjini yemoto ithatha ingxenye emise oku-1.Isigaba esinomumo ongu-1 singanciphisa ubukhulu ngaphansi kwesimo sokuqina namandla okwanele.Ingxenye emise okwe-H isetshenziselwa injini enamandla amakhulu.Ezinye izinjini zisebenzisa induku yokuxhuma enekhanda elincane ukujova uwoyela ukuze ipholise ipiston.Izimbobo kufanele zibhojwe ngobude emzimbeni wenduku.Ukuze ugweme ukugxila kokucindezeleka, umzimba wenduku yokuxhuma kanye nekhanda elincane nekhanda elikhulu lixhunywe ukuguqulwa okubushelelezi kwe-arc enkulu.
Ukuze kuncishiswe ukudlidliza kwenjini, umehluko omkhulu wenduku yokuxhuma isilinda ngayinye kufanele ulinganiselwe kububanzi obuncane.Lapho kuhlanganisa injini efektri, igramu ngokuvamile ithathwa njengeyunithi yokulinganisa ngokwesisindo sekhanda elingezansi lenduku yokuxhuma, futhi iqembu elifanayo lenduku yokuxhuma likhethwa injini efanayo.
Enjinini yohlobo lwe-V, amasilinda ahambisanayo kumakholomu angakwesokunxele nangakwesokudla ahlanganyela iphini lokukhala, futhi induku yokuxhuma inezinhlobo ezintathu: induku yokuxhuma ehambisanayo, induku yokuxhuma imfologo kanye nenduku yokuxhuma eyinhloko neyisisizi.
