Iyini i-camshaft - intake emotweni?
Enjinini yezimoto, igama elithi "camshaft - intake" livame ukubhekisela ku-camshaft ye-intake, umsebenzi wayo ukulawula ukuvulwa nokuvalwa kwama-valve okungenisa, ukuqinisekisa ukuthi umoya omusha (noma ingxube evuthayo) ungena kwisilinda ngesikhathi esifanele sokusha.
Ngokusho kolwazi lomphakathi, izincazelo zezimpawu eziku-camshaft yilezi ezilandelayo:
"Mina" noma "ngaphakathi" imele i-intake (Intake)
"E" noma "ex" imele i-exhaust (i-Exhaust)
Ngakho-ke, igama elithi "camshaft - intake" libhekisela ku-camshaft intake, futhi imisebenzi yayo eyinhloko ihlanganisa:
Uma i-piston yehla, isunduza i-intake valve ivuleke ukuze idonse umoya noma ingxube kaphethiloli nomoya;
Ukulawula isikhathi kanye nokuphakanyiswa kwe-intake valve yokuvula nokuvala, okuthinta ngqo ukusebenza kahle kwenjini kokushaja, ukukhishwa kwamandla, kanye nokonga uphethiloli;
Ukusebenza ngokubambisana ne-camshaft yokukhipha umoya ukuqinisekisa inqubo yokusatshalaliswa kwamavalvu enjini enembile nehlelekile.
Indlela yokuhlukanisa i-camshaft yokungenisa
Bheka uphawu: ngokuvamile luphawulwa ngokuthi "Mina" noma "ngaphakathi";
Bheka indawo: eduze kwe-intake manifold;
Bheka isakhiwo: kwamanye amamodeli, i-camshaft yokungenisa inenzwa yesikhundla se-camshaft noma ijeneretha yesignali emsileni;
Maka ngaphambi kokuqaqa: uma kungekho uphawu olucacile, bhala phansi ngaphambi kokuqaqa ukuze ugweme ukudideka.
Qaphela: Abakhiqizi abahlukene bangasebenzisa izindlela zokuqamba ezihlukile kancane (njengoba ezinye izinto zisho ukuthi "ku" imele intake ), kodwa indinganiso evamile neyemboni yi-I = intake, E = exhaust
"Umsebenzi wokungenisa" we-camshaft enjinini yezimoto uvame ukubhekisela emsebenzini wawo oyinhloko enqubweni yokufaka, okungukuthi, ukulawula ukuvulwa nokuvalwa kwevalvu yokufaka, ukuqinisekisa ukuthi injini isebenza kahle nangokuzinzile.
Ngokusho kolwazi olusemthethweni lomphakathi, "umsebenzi wokungenisa" we-camshaft ubonakala ngqo kulezi zici ezilandelayo:
Ukulawula isikhathi sokuvulwa nokuvalwa kwe-valve yokungenisa: I-camshaft, eqhutshwa yi-crankshaft nge-cam yayo yokungenisa, ijikeleza ngesigaba esinqunyiwe, ilawula ngokunembile i-valve yokungenisa yesilinda ngasinye ukuthi ivuleke ekuqaleni kwe-stroke yokungenisa futhi ivale ngaphambi kwe-stroke yokucindezela, iqinisekisa ukuthi umoya omusha (noma ingxube evuthayo) ingena kwisilinda ngesikhathi .
Ukuthuthukisa ukusebenza kahle kokushaja: Iphrofayili yekhamera yokungenisa (ngokuvamile efana neqanda) ithinta ngqo ukuphakama kwevalvu kanye nobude bokuvula, ngaleyo ndlela ithinta ukusebenza kahle kokushaja kwesilinda. Umklamo omuhle ungathuthukisa ukukhishwa kwamandla enjini kanye nokonga uphethiloli.
Ukusebenzisana nohlelo lwesikhathi: Ezinjinini ezifakwe i-variable valve timing (VVT), i-angle ye-camshaft ingalungiswa ngokuguquguqukayo yi-ECU ngokuya ngezimo zokusebenza, okwenza isikhathi sokungenisa sisebenze kangcono ukuze sivumelane nesivinini esihlukile nezidingo zomthwalo.
Izesekeli ezihlobene nokushayela: Amanye ama-camshaft ahlanganisa namasondo noma amagiya angajwayelekile ukuze ashayele izesekeli ezifana namaphampu kaphethiloli namaphampu kawoyela, okusekela ngokungaqondile ukusebenza okuvamile kohlelo lokungenisa.
Qaphela: I-camshaft ngokwayo ayisebenzisi "ukungenisa" ngokuqondile, kodwa ifinyelela ukuphathwa okunembile kwenqubo yokungenisa ngesenzo se-valve yokungenisa. Ngakho-ke, "umsebenzi wokungenisa" empeleni uwumsebenzi wokusabalalisa i-valve yokungenisa.
