Imikhiqizo
I-camshaft esebenza kahle kakhulu yenjini ye-Dongfeng DF486
I-camshaft yethu yenziwe ngokucophelela kusetshenziswa amasu okukhiqiza athuthukile kanye nezinto ezisezingeni eliphezulu. Kusetshenziswa izinyathelo zokulawula ikhwalithi eqinile kuyo yonke inqubo yokukhiqiza ukuqinisekisa ukuthi i-camshaft ihlangabezana nezimiso eziqondile kanye nokubekezelelana okudingekayo ukuze injini isebenze kahle. Kugxilwe kakhulu ekubunjweni okunembile kanye nokuqinisekiswa kwekhwalithi.
I-camshaft yethu ikhiqizwa kusetshenziswa izinto ezisezingeni eliphezulu ezifana ne-ductile iron, okuqinisekisa amandla nokuqina okumangalisayo. Lezi zinto zikhethwa ngenxa yekhono lazo lokubekezelela ukucindezeleka okuphezulu kanye namazinga okushisa atholakala ngaphakathi kwenjini, okunikeza ukusebenza okuthembekile esikhathini eside. I-camshaft yakhiwe ngokunemba ukuze inikeze isikhathi esifanele se-valve, ithuthukise ukusebenza kahle kwenjini kanye nokukhishwa kwamandla. Ukwakhiwa kwayo okuqinile kanye nomklamo wayo oqondile kuyenza ibe yingxenye ebalulekile ekuqinisekiseni ukusebenza kahle nangokushelela kwenjini ye-Dongfeng DF486.
Izinto zokwakha ze-camshaft kumele zikhethwe ngokuqinile ngokwezidingo zomklamo, futhi ikhwalithi yezinto zokwakha kumele ihlangabezane nezindinganiso ezibekiwe. Ngesikhathi senqubo yokukhiqiza, kudingeka imishini yokukhiqiza ethuthukisiwe kanye namasu ukuqinisekisa ukunemba kanye nekhwalithi yemikhiqizo. Ngesikhathi senqubo yokukhiqiza, kumele kuqaliswe izinyathelo zokulawula ikhwalithi eziqinile ukuqinisekisa ukuthi imikhiqizo ihlangabezana nezidingo zokuklama kanye nezindinganiso zekhwalithi. Ekuphetheni, umkhiqizo we-camshaft wokukhiqiza udinga ukulawulwa kwekhwalithi okuqinile kanye nobuchwepheshe bokukhiqiza obuthuthukisiwe ukuqinisekisa ikhwalithi kanye nokuphepha kwemikhiqizo.
I-camshaft iyisici esibalulekile esinomthwalo wokulawula ukuvulwa nokuvalwa kwamavalvu enjini. Yaklanywa ngokunemba ukuqinisekisa ukusebenza kahle kanye nokusebenza kahle. I-camshaft yenziwe ngezinto ezisezingeni eliphezulu futhi ihlolwa kanzima ukuqinisekisa ukuqina nokuthembeka. Umklamo wayo onembile kanye nobunjiniyela kunegalelo ekusebenzeni kahle kwenjini, okuholela ekukhiqizweni kwamandla okuphumelelayo kanye nokunciphisa ukukhishwa kwegesi.
