I-Intake manifold.
Kwiinjini ze-carburetor okanye i-throttle body, i-input manifold ibhekisa kumbhobho wokungenisa ovela ngasemva kwe-carburetor okanye i-throttle body ukuya ngaphambi kwe-input head ye-cylinder head. Umsebenzi wayo kukusasaza umxube womoya kunye namafutha kwi-input nganye ye-cylinder nge-carburetor okanye i-throttle body.
Kwinjini yokufaka ipetroli okanye injini yedizili, i-incase manifold isasaza umoya ococekileyo kwi-cylinder intakes. I-incase manifold kufuneka isasaze umoya, umxube wepetroli okanye umoya ococekileyo ngokulinganayo kwi-cylinder nganye, ukuze ubude bomjelo wegesi kwi-incase manifold bulingane kangangoko. Ukuze kuncitshiswe ukumelana nokuhamba kwegesi kwaye kuphuculwe umthamo wokungenisa, udonga lwangaphakathi lwe-incase manifold kufuneka lube bushelelezi.
Ngaphambi kokuba sithethe nge-input manifold, makhe sicinge ngendlela umoya ongena ngayo enjinini. Kwintshayelelo yenjini, sikhankanye ukusebenza kwepiston kwisilinda, xa injini ikwi-intake stroke, i-piston iyehla ukuze ivelise i-vacuum kwisilinda (oko kukuthi, uxinzelelo luba ncinci), ukuze kubekho umahluko woxinzelelo nomoya wangaphandle, ukuze umoya ungene kwisilinda. Umzekelo, wonke umntu bekufanele ukuba ufakwe inaliti aze abone indlela umongikazi afunxe ngayo iyeza kwibhakethi yenaliti! Ukuba ibhakethi yenaliti yinjini, xa i-piston ekwibhakethi yenaliti ikhutshwa, ulwelo luya kufunxwa kwibhakethi yenaliti, kwaye le yindlela injini etsala ngayo umoya kwisilinda.
Ngenxa yobushushu obuphantsi besiphelo sokungenisa, izinto ezidityanisiweyo ziye zaba yinto ethandwayo yokungenisa izinto ezininzi, ekhaphukhaphu kwaye igudile ngaphakathi, inokunciphisa ngempumelelo ukumelana nokunyuka nokusebenza kakuhle kokungenisa.
Isizathu segama
I-input manifold ifumaneka phakathi kwe-throttle valve kunye ne-injection valve ye-injini, isizathu sokuba ibizwa ngokuba yi-"manifold" kukuba emva kokuba umoya ungene kwi-throttle valve, emva kwenkqubo ye-manifold buffer, itshaneli yokuhamba komoya "yahlulwe" apha, ihambelana nenani lee-cylinders ze-injini, njenge-injini ye-cylinder ezine ineetshaneli ezine, kwaye i-injini ye-cylinder ezintlanu ineetshaneli ezintlanu, kwaye umoya ungeniswa ngokwahlukeneyo kwi-cylinders. Kwi-injection ye-injection yendalo, kuba i-input manifold ifumaneka emva kwe-throttle valve, xa i-injection throttle ye-injini ivuliwe, i-cylinder ayinakufunxa umoya owaneleyo, nto leyo eya kubangela i-vacuum ephezulu ye-manifold; Xa i-injection throttle ye-injection ivuliwe, i-vacuum kwi-injection manifold iya kuba ncinci. Ke ngoko, i-injection fuel supply injini iya kufakela i-pressure gauge kwi-injection manifold ukuze inike i-ECU ukumisela umthwalo we-injini kwaye inike ubungakanani obufanelekileyo be-injection fuel.
Iindlela ezahlukeneyo zokusetyenziswa
I-vacuum enemibala emininzi ayisetyenziselwa kuphela ukubonelela ngemiqondiso yoxinzelelo ukumisela umthwalo wenjini, zininzi iindlela ezisetyenziswayo! Ukuba i-brake ikwafuna ukusebenzisa i-vacuum yenjini ukunceda, ngoko ke xa injini iqala, i-pedal ye-brake iya kuba lula kakhulu, ngenxa yoncedo lwe-vacuum. Kukwakho neendlela ezithile zokulawula isantya ezihlala zihleli ezisebenzisa i-vacuum enemibala emininzi. Nje ukuba ezi tyhubhu ze-vacuum zivuza okanye ziguqulwe ngendlela engafanelekanga, ziya kubangela ukuphazamiseka kolawulo lwenjini kwaye zichaphazele ukusebenza kwe-brake, ngoko ke abafundi bayacetyiswa ukuba bangenzi utshintsho olungafanelekanga kwiityhubhu ze-vacuum ukugcina ukhuseleko lokuqhuba.
Uyilo olukrelekrele
Uyilo lwe-Intake manifold nalo lulwazi oluninzi, ukuze injini ifane, ubude be-cylinder nganye kunye nokugoba kufuneka kufane kangangoko kunokwenzeka. Ekubeni injini isebenza ngee-strokes ezine, i-cylinder nganye yenjini iya kupompa ngendlela ye-pulse, kwaye ngokomthetho, i-manifold ende ifanelekile kwi-RPM ephantsi, ngelixa i-manifold emfutshane ifanelekile kwi-RPM ephezulu. Ke ngoko, ezinye iimodeli ziya kusebenzisa ii-manifples ze-incase eziguquguqukayo, okanye ii-manifples ze-incase eziguquguqukayo eziqhubekayo, ukuze injini ikwazi ukudlala ngcono kuzo zonke iindawo zesantya.
ubukhulu
Inzuzo ephambili ye-plastic intake manifold yindleko yayo ephantsi kunye nobunzima obulula. Ukongeza, ekubeni i-PA iqhuba ubushushu obuphantsi kune-aluminium, i-nozzle yepetroli kunye nobushushu bomoya obungenayo buphantsi. Ayinakuphucula kuphela ukusebenza kokuqala okushushu, iphucule amandla kunye ne-torque yenjini, kodwa ikwathintela ukulahleka kobushushu kwityhubhu ukuya kwinqanaba elithile xa iqala ukubanda, ikhawulezise ukunyuka kobushushu begesi, kwaye udonga lwe-plastic intake manifold lugudile, nto leyo enokunciphisa ukumelana nokuhamba komoya, ngaloo ndlela iphucule ukusebenza kwenjini.
Ngokuphathelele ixabiso, ixabiso lezinto ezibonakalayo ze-plastic intake manifold lifana kakhulu nele-aluminium intake manifold, kwaye i-plastic intake manifold yenziwe kube kanye, ngesantya esiphezulu sokudlula; Isivuno se-aluminium intake manifold blank casting siphantsi, iindleko zomatshini ziphezulu, ngoko ke iindleko zokuvelisa ze-plastic intake manifold ziphantsi ngama-20%-35% kuneze-aluminium intake manifold.
Imfuneko yezinto eziphathekayo
1) Ukumelana nobushushu obuphezulu: i-plastic intake manifold iqhagamshelwe ngqo kwintloko yesilinda yenjini, kwaye ubushushu bentloko yesilinda yenjini bunokufikelela kwi-130 ~ 150℃. Ke ngoko, izinto ze-plastic intake manifold ziyafuneka ukuze zikwazi ukumelana nobushushu obuphezulu be-180 ° C.
2) Amandla aphezulu: i-manifold yeplastiki ifakwe kwinjini, ukumelana nomthwalo wokungcangcazela kwenjini yemoto, umthwalo we-throttle kunye ne-sensor inertial force, umthwalo we-pulsation woxinzelelo lokungenisa, njl.njl., kodwa nokuqinisekisa ukuba injini ayidutyulwa nguxinzelelo lwe-pulsation loxinzelelo oluphezulu xa kwenzeka i-tempering engaqhelekanga.
3) Uzinzo lobukhulu: Iimfuneko zokunyamezela ubukhulu bonxibelelwano phakathi kwe-intake manifold kunye nenjini zingqongqo kakhulu, kwaye ukufakwa kwee-sensors kunye nee-actuators kwi-manifold kufuneka kuchaneke kakhulu.
4) Uzinzo lweekhemikhali: i-plastic intake manifold idibana ngqo nepetroli kunye ne-antifreeze coolant xa isebenza, ipetroli sisinyibilikisi esinamandla, kwaye i-glycol ekwi-coolant nayo iya kuchaphazela ukusebenza kweplastiki, ngoko ke, uzinzo lweekhemikhali zezinto ze-plastic intake manifold luphezulu kakhulu kwaye kufuneka luvavanywe ngokungqongqo.
5) Uzinzo lokuguga kobushushu; Injini yemoto isebenza phantsi kobushushu obuqinileyo, ubushushu bokusebenza butshintsha kwi-30 ~ 130 ° C, kwaye izinto zeplastiki kufuneka zikwazi ukuqinisekisa ukuthembeka kwexesha elide kwe-manifold.
