I-Cummins Engine Parts Exhaust Valve 3921444/3802085 ye-Cummins 6C8.3 Injini

Ingcaciso yeMveliso

Ivalve yenziwe yintloko yevalve kunye nesiqu.Ubushushu bentloko yevalve buphezulu kakhulu (ivalve yokungena yi-570 ~ 670K, ivalve yokukhupha i-1050 ~ 1200K), kwaye ikwathwala uxinzelelo lwegesi, amandla entwasahlobo yevalve kunye namandla e-inetia yamacandelo othumelo.I-lubrication yayo kunye neemeko zokupholisa zihluphekile, kwaye i-valve kufuneka ifuneke Inamandla athile, ukuqina, ukumelana nokushisa kunye nokuxhatshazwa kokugqoka.

Umsebenzi wevalve unoxanduva ngokukodwa lokungenisa umoya kwi-injini kunye nokukhupha igesi yokukhupha emva kokutsha.Ukusuka kwisakhiwo se-injini, yahlulwe yaba yivalve yokungena kunye nevalve yokukhupha.Umsebenzi wevalve yokungena kukufunxa umoya kwi-injini kwaye udibanise kwaye utshise namafutha;umsebenzi we-valve yokukhupha i-valve yokukhupha igesi yokukhupha igesi etshiswayo kunye nokutshabalalisa ubushushu.

Ukuze kuphuculwe ukusebenza kakuhle kokungena kunye nokuphuma, iteknoloji ye-valve eninzi isetyenziswa ngoku.Kuqhelekile ukuba i-cylinder nganye ihlelwe ngee-valve ezi-4 (kukho kwakhona i-cylinder eyodwa yoyilo kunye ne-3 okanye i-5 valves, umgaqo uyafana).Iisilinda ezi-4 zineevalve ezili-16 zizonke.I-"16V" ehlala ibonwa kwizixhobo zemoto ithetha ukuba i-injini ineevalvu ezili-16 zizonke.Olu hlobo lwesakhiwo se-valve eninzi kulula ukwenza igumbi elidibeneyo lokutshisa.I-injector ihlelwe embindini, enokwenza umxube we-oyile kunye negesi uvutha ngokukhawuleza kwaye ngokulinganayo.Ubunzima kunye nokuvulwa kwevalve nganye kuncitshiswe ngokufanelekileyo, ukwenzela ukuba i-valve inokuvulwa okanye ivalwe ngokukhawuleza.
