Ukungenisa ngokuphindaphindiweyo.
Kwi-carburetor okanye i-throttle body injection ye-injini yepetroli, i-manifold intake ibhekiselele kumbhobho wokuthatha osuka emva kwecarburetor okanye umzimba we-throttle ukuya phambi kwe-cylinder head port. Umsebenzi wayo kukuhambisa umoya kunye nomxube wamafutha kwi-cylinder nganye yokuthatha i-port nge-carburetor okanye i-throttle body.
Kwi-injini ye-port fuel injection okanye injini ye-diesel, i-manifold intake isasaza umoya ococekileyo kwi-cylinder intakes. I-manifold yokungenisa kufuneka isasaze umoya, umxube we-fuel okanye umoya ococekileyo ngokulinganayo kangangoko kunokwenzeka kwi-cylinder nganye, ukwenzela ukuba ubude bomzila wegesi kwi-manifold yokuthatha kufuneka bulingane ngokusemandleni. Ukuze kuncitshiswe ukuxhathisa kokuhamba kwegesi kunye nokuphucula umthamo wokungena, udonga lwangaphakathi lwe-manifold yokuthatha kufuneka lube lula.
Ngaphambi kokuba sithethe ngobuninzi bokuthatha, makhe sicinge malunga nokuba umoya ungena njani enjinini. Kwintshayelelo ye-injini, sikhankanye ukusebenza kwepiston kwi-cylinder, xa i-injini ikwi-stroke yokuthatha, ipiston yehla ukuze ivelise i-vacuum kwi-cylinder (oko kukuthi, uxinzelelo luba luncinci), ukuze Umahluko woxinzelelo kunye nomoya wangaphandle unokuveliswa, ukuze umoya ungene kwi-cylinder. Umzekelo, wonke umntu bekufanele ukuba utofwe kwaye ubone ukuba umongikazi walifunxa njani iyeza kwi-emele yenaliti! Ukuba i-emele yenaliti yi-injini, ngoko xa ipiston kwi-emele yenaliti ikhutshiwe, ulwelo luya kutsalwa kwi-emele yenaliti, kwaye yile ndlela injini itsala ngayo umoya kwi-cylinder.
Ngenxa yokushisa okuphantsi kokuphela kokuthatha, izinto ezidibeneyo ziye zaba yinto eyaziwayo yokuthatha izinto ezininzi, ezilula kwaye zigudileyo ngaphakathi, zinokunciphisa ngokufanelekileyo ukuchasana kunye nokwandisa ukusebenza kakuhle kokuthatha.
Isizathu segama
I-manifold intake iphakathi kwevalve ye-throttle kunye ne-injini yokungenisa i-injini, isizathu sokuba kuthiwe "i-manifold" kukuba emva kokuba umoya ungene kwi-valve ye-throttle, emva kwenkqubo ye-buffer ephindaphindiweyo, umjelo wokuhamba komoya "wahluliwe" apha, ehambelana nenani leesilinda ze-injini, ezifana ne-injini ye-cylinder emine ineendlela ezine, kunye ne-injini ye-cylinder emihlanu ineendlela ezinhlanu, kwaye umoya ungeniswe ngokulandelelana iisilinda. Kwi-injini yokungena yendalo, kuba i-manifold intake ifumaneka emva kwevalve ye-throttle, xa i-injini ye-throttle ivuliwe, i-cylinder ayikwazi ukufunxa umoya owaneleyo, oya kubangela i-vacuum ephezulu; Xa i-throttle ye-injini ivuliwe, i-vacuum kwi-intake manifold iya kuba ncinane. Ke ngoko, i-injini yokubonelela ngamafutha e-injini iya kufaka igeyiji yoxinzelelo kwi-manifold yokuthatha ukubonelela i-ECU ukumisela umthwalo we-injini kwaye inike ubungakanani obufanelekileyo benaliti yamafutha.
Ukusetyenziswa okwahlukeneyo
Ivacuum eninzi ayisetyenziswanga kuphela ukubonelela ngemiqondiso yoxinzelelo ukufumanisa umthwalo wenjini, zininzi izinto ezisetyenziswayo! Ukuba i-brake ifuna ukusebenzisa i-vacuum ye-injini ukuncedisa, ngoko xa injini iqala, i-pedal ye-brake iya kuba khaphukhaphu kakhulu, ngenxa yoncedo lwe-vacuum. Kukwakho nezinye iindlela zolawulo lwesantya esingaguqukiyo ezisebenzisa ivacuum eninzi. Nje ukuba ezi ityhubhu zokufunxa zivuze okanye zitshintshwe ngendlela engafanelekanga, oko kuya kubangela ukuphazamiseka kolawulo lwe-injini kwaye kuchaphazele ukusebenza kwe-brake, ngoko ke abafundi bayacetyiswa ukuba bangenzi uhlengahlengiso olungafanelekanga kwiityhubhu zokufunxa ukugcina ukhuseleko lokuqhuba.
Uyilo olukrelekrele
Uyilo oluninzi lwe-Intake lukwaluninzi lolwazi, ukwenzela ukuba i-injini nganye imeko yokutshisa i-cylinder iyafana, ubude be-cylinder nganye kunye nokugoba kufuneka kufane njengoko kunokwenzeka. Ekubeni i-injini iqhutywe yimivimbo emine, i-cylinder nganye ye-injini iya kuphonswa kwimodi ye-pulse, kwaye njengomthetho wesithupha, i-manifold ende ifanelekile ekusebenzeni kwe-RPM ephantsi, ngelixa i-manifold emfutshane ifanelekile ekusebenzeni kwe-RPM ephezulu. Ke ngoko, ezinye iimodeli ziya kusebenzisa ubude obuguquguqukayo bokuthatha i-maniifples, okanye ubude obuguquguqukayo obuqhubekayo be-maniifples, ukuze injini idlale ukusebenza okungcono kuyo yonke imimandla yesantya.
ukongama
Inzuzo ephambili yobuninzi beplastiki yindleko yayo ephantsi kunye nobunzima obulula. Ukongeza, ekubeni i-thermal conductivity ye-PA iphantsi kune-aluminium, i-nozzle ye-fuel kunye nobushushu bomoya obungenayo buphantsi. Ayinakuphucula kuphela ukusebenza kokuqala okushushu, ukuphucula amandla kunye ne-torque ye-injini, kodwa ikwanqande ilahleko yobushushu kwityhubhu ukuya kuthi ga kwinqanaba elithile xa kuqalwa kubanda, ukukhawulezisa ukwanda kobushushu berhasi, kunye nodonga oluphangaleleyo lweplastiki. egudileyo, enokunciphisa ukumelana nokuhamba komoya, ngaloo ndlela iphucula ukusebenza kwe-injini.
Ngokwendleko, ixabiso lezinto eziphathekayo zeplastiki yokuthatha izinto ezininzi ngokusisiseko ziyafana nezo ze-aluminiyam yokuthatha ngokuphindaphindiweyo, kwaye i-plastiki intake manifold yenziwe kanye, kunye nereyithi yokupasa ephezulu; I-aluminiyam ethatha ngokuphindaphindiweyo imveliso yokuphosa engenanto iphantsi, ixabiso lomatshini liphezulu kakhulu, ngoko ke ixabiso lemveliso yeplastiki yokuthatha ngokuphindaphindiweyo ngama-20% -35% ngaphantsi kune-aluminiyam yokuthatha ngokuphindaphindiweyo.
Imfuneko yezinto eziphathekayo
I-1) Ukumelana nobushushu obuphezulu: iplastiki yokuthatha izinto ezininzi iqhagamshelwe ngokuthe ngqo kwintloko ye-injini ye-cylinder, kunye nobushushu bentloko ye-injini ye-cylinder inokufikelela kwi-130 ~ 150 ℃. Ke ngoko, izinto ezininzi zeplastiki ezithathayo ziyafuneka ukumelana nobushushu obuphezulu be-180 ° C.
2) Amandla aphezulu: iplastiki eninzi ifakwe kwi-injini, ukumelana nomthwalo wokungcangcazela kwe-injini yemoto, i-throttle kunye ne-sensor inertial force load, i-intake pressure pulsation load, njl., kodwa nokuqinisekisa ukuba i-injini ayiqhumanga ngoxinzelelo oluphezulu. uxinzelelo lwe-pulsation xa ukucaphuka okungaqhelekanga kwenzeka.
3) Uzinzo lweDimensional: Iimfuno zonyamezelo lwe-dimensional zokudibanisa phakathi kwe-intake manifold kunye ne-injini zingqongqo kakhulu, kunye nofakelo lwe-sensor kunye ne-actuators kwi-manifold kufuneka ichaneke kakhulu.
4) Uzinzo kwiChemical: iplastiki yokuthatha i-manifold inxibelelana ngokuthe ngqo nepetroli kunye ne-antifreeze coolant xa isebenza, i-petroli sisinyibilikisi esinamandla, kwaye i-glycol kwi-coolant iya kuchaphazela ukusebenza kweplastiki, ngoko ke, ukuzinza kweekhemikhali zeplastiki. I-manifold material iphezulu kakhulu kwaye ifuna ukuvavanywa ngokungqongqo.
5) Ukuzinza kokuguga kwe-Thermal; Injini yemoto isebenza phantsi kobushushu oburhabaxa kakhulu, ubushushu bokusebenza buguquka kwi-30 ~ 130 ° C, kwaye izinto zeplastiki kufuneka zikwazi ukuqinisekisa ukuthembeka kwexesha elide lezinto ezininzi.
