Yintoni i-camshaft - intake emotweni?
Kwinjini yeemoto, igama elithi "camshaft - intake" lidla ngokubhekisa kwi-intake camshaft, umsebenzi wayo kukulawula ukuvulwa nokuvalwa kweevalvu zokungenisa, ukuqinisekisa ukuba umoya omtsha (okanye umxube ovuthayo) ungena kwisilinda ngexesha elifanelekileyo lokutsha.
Ngokweenkcukacha zoluntu, intsingiselo yeempawu ezikwi-camshaft zezi zilandelayo:
"Ndi" okanye "ngaphakathi" zimele i-intake (Intake)
"E" okanye "ex" imele i-exhaust (i-Exhaust)
Ngoko ke, igama elithi "camshaft - intake" libhekisa kwi-intake camshaft, kwaye imisebenzi yayo ephambili ibandakanya:
Xa i-piston isiya ezantsi, ityhala ivalvu yokungenisa ivuleke ukuze itsale umoya okanye umxube wefutha-moya;
Ukulawula ixesha kunye nokuphakanyiswa kwevalvu yokungenisa, okuchaphazela ngokuthe ngqo ukusebenza kakuhle kwenjini, amandla okukhupha, kunye nokonga amafutha;
Ukusebenza ngokubambisana ne-ekzosi ye-camshaft ukuqinisekisa inkqubo yokusasazwa kweevalvu zenjini echanekileyo necwangcisiweyo.
Indlela yokwahlula i-camshaft yokungenisa
Jonga uphawu: ludla ngokubhalwa njengo "Mna" okanye "ngaphakathi";
Jonga indawo ekuyo: kufutshane ne-intake manifold;
Jonga ulwakhiwo: kwezinye iimodeli, i-camshaft yokungenisa ine-sensor yendawo ye-camshaft okanye i-signal generator emsileni;
Phawula ngaphambi kokuqhaqha: ukuba akukho phawu lucacileyo, bhala inqaku ngaphambi kokuqhaqha ukuze uphephe ukudideka.
Qaphela: Abavelisi abahlukeneyo banokusebenzisa iindlela ezahlukeneyo zokubiza amagama (ezifana nezinye izinto ezikhankanyiweyo ukuba "kwi" imele intake ), kodwa umgangatho oqhelekileyo noweshishini ngu I = intake, E = exhaust
"Umsebenzi wokungenisa" we-camshaft kwinjini yemoto udla ngokubhekisa kumsebenzi wayo ophambili kwinkqubo yokufaka, oko kukuthi, ukulawula ukuvulwa nokuvalwa kwevalvu yokufaka, ukuqinisekisa ukuba injini isebenza ngokufanelekileyo nangokuzinzileyo.
Ngokwengxelo kawonke-wonke enegunya, "umsebenzi wokungenisa" we-camshaft ubonakala ngokukodwa kwezi zinto zilandelayo:
Ukulawula ixesha lokuvulwa nokuvalwa kwevalvu yokungenisa: I-camshaft, eqhutywa yi-crankshaft kwi-cam yayo yokungenisa, ijikeleza kwisigaba esimiselweyo, ilawula ngokuchanekileyo ivalvu yokungenisa yesilinda nganye ukuba ivuleke ekuqaleni kwe-stroke yokungenisa kwaye ivale ngaphambi kwe-stroke yoxinzelelo, iqinisekisa ukuba umoya omtsha (okanye umxube ovuthayo) ungena kwisilinda ngexesha
Ukuphucula ukusebenza kakuhle kokutshaja: Iprofayili yekhamera yokungenisa (ehlala imile okweqanda) ichaphazela ngokuthe ngqo ixesha lokuphakanyiswa kwevalvu kunye nokuvulwa kwayo, ngaloo ndlela ichaphazela ukusebenza kakuhle kokutshaja kwesilinda. Uyilo oluhle lunokuphucula amandla enjini kunye nokonga amafutha.
Ukusebenzisana nenkqubo yexesha: Kwiinjini ezixhotyiswe nge-variable valve timing (VVT), i-angle ye-camshaft inokulungiswa ngokuguquguqukayo yi-ECU ngokweemeko zokusebenza, nto leyo ephucula ngakumbi ixesha lokungenisa ukuze lihambelane nesantya esahlukileyo kunye neemfuno zomthwalo.
Izixhobo ezinxulumene nokuqhuba: Ezinye ii-camshafts zikwadibanisa amavili okanye iigiya ezingaqhelekanga ukuze ziqhube izixhobo ezifana neempompo zepetroli kunye neempompo zeoyile, zixhasa ngokungathanga ngqo ukusebenza okuqhelekileyo kwenkqubo yokungenisa.
Qaphela: I-camshaft ngokwayo ayisebenzisi ngqo "ukungenisa", kodwa ifezekisa ulawulo oluchanekileyo lwenkqubo yokungenisa ngesenzo sevalvu yokungenisa. Ke ngoko, "umsebenzi wokungenisa" ngumsebenzi wokusasazwa kwevalvu yokungenisa.
