Ukungenisa okuningi.
Ezinjini zomjovo zikaphethiloli we-carburetor noma we-throttle body, i-manifold intake isho ipayipi elidonsayo elisuka ngemuva kwe-carburetor noma umzimba we-throttle ukuya ngaphambi kwembobo ye-cylinder head. Umsebenzi wayo ukusabalalisa ingxube yomoya kanye nophethiloli embotsheni ngayinye yokuthatha isilinda nge-carburetor noma i-throttle body.
Enjinini yomjovo kaphethiloli wembobo noma injini yedizili, i-manifold ewuthathayo ivele isabalalise umoya ohlanzekile kumasilinda. I-manifold yokuthatha kufanele isabalalise umoya, ingxube kaphethiloli noma umoya ohlanzekile ngokulinganayo ngangokunokwenzeka kusilinda ngasinye, ukuze ubude besiteshi segesi ku-manifold wokukhipha kufanele bulingane ngangokunokwenzeka. Ukuze kuncishiswe ukumelana nokugeleza kwegesi futhi kuthuthukiswe umthamo wokungena, udonga lwangaphakathi lwe-multifold intake kufanele lube bushelelezi.
Ngaphambi kokuba sikhulume ngenqwaba yezinto eziwuthathayo, ake sicabange ukuthi umoya ungena kanjani enjinini. Esethulweni senjini, sikhulume ngokusebenza kwepiston kusilinda, uma injini ikwi-stroke edonsayo, i-piston iyehla ikhiphe i-vacuum ku-cylinder (okungukuthi, umfutho ube mncane), ukuze umehluko wengcindezi nomoya wangaphandle ungakhiqizwa, ukuze umoya ungene kusilinda. Isibonelo, wonke umuntu bekufanele ajovwe abone ukuthi umhlengikazi wawumunca kanjani umuthi ebhakedeni yenaliti! Uma ibhakede yenaliti iyinjini, lapho piston ebhakedeni yenaliti ikhishwa, uketshezi luzomuncwa ebhakedeni yenaliti, futhi yile ndlela injini edonsa ngayo umoya ku-cylinder.
Ngenxa yokushisa okuphansi kokuphela kokuthatha, izinto ezihlanganisiwe ziye zaba yinto ethandwayo yokudla okuhlukahlukene, okulula futhi okubushelelezi ngaphakathi, kunganciphisa ngempumelelo ukumelana nokwandisa ukusebenza kahle kokuthatha.
Isizathu segama
I-multifold intake itholakala phakathi kwe-valve ye-throttle kanye ne-valve yokungenisa injini, isizathu sokuthi kungani ibizwa ngokuthi "i-multifold" ukuthi ngemva kokuba umoya ungena ku-valve ye-throttle, ngemva kwesistimu ye-buffer ehlukahlukene, isiteshi sokugeleza komoya "sihlukaniswe" lapha, okuhambisana nenani lamasilinda enjini, njengenjini enamasilinda amane inamashaneli amane, kanti injini eyi-five-cylinder ineziteshi ezinhlanu, futhi umoya ungeniswa ngokulandelana. amasilinda. Ngenjini yokungenisa yemvelo, ngoba i-multifold intake itholakala ngemuva kwe-valve ye-throttle, lapho i-throttle injini ivulekile, isilinda asikwazi ukumunca umoya owanele, okuzoholela ku-vacuum ephakeme eminingi; Lapho i-throttle yenjini ivuliwe, i-vacuum ku-multitake intake iba yincane. Ngakho-ke, injini yokunikeza uphethiloli womjovo izofaka igeji yokucindezela ku-manifold yokuthatha ukuze inikeze i-ECU ukunquma umthamo wenjini futhi inikeze inani elifanele lomjovo kaphethiloli.
Ukusetshenziswa okuhlukile
I-vacuum eminingi ayisetshenziselwa ukunikeza amasignali engcindezi kuphela ukuze kutholwe umthamo wenjini, kuningi ukusetshenziswa! Uma ibhuleki lidinga ukusebenzisa i-vacuum yenjini ukusiza, ngakho-ke uma injini iqala, i-pedal ye-brake izoba lula kakhulu, ngenxa yosizo lwe-vacuum. Kukhona futhi ezinye izinhlobo zezindlela eziqhubekayo zokulawula isivinini ezisebenzisa i-vacuum ehlukahlukene. Uma la mashubhu e-vacuum eputshukile noma engashintshwa ngendlela engafanele, lokho kuzodala ukuphazamiseka kokulawula injini futhi kuthinte ukusebenza kwamabhuleki, ngakho abafundi bayelulekwa ukuthi bangenzi izinguquko ezingafanele kumashubhu e-vacuum ukuze kugcinwe ukuphepha kokushayela.
Umklamo ohlakaniphile
Idizayini eningi yokungenisa nayo iwulwazi oluningi, ukuze injini isimo sokusha isilinda ngasinye siyefana, ubude nokugoba kwesilinda ngasinye kufanele kufane ngangokunokwenzeka. Njengoba injini isebenza ngemivimbo emine, isilinda ngasinye senjini sizopontshwa ngendlela ye-pulse, futhi njengomthetho wesithupha, i-manifold ende ifanele ukusebenza kwe-RPM ephansi, kuyilapho i-manifold emfushane ifanele ukusebenza kwe-RPM ephezulu. Ngakho-ke, amanye amamodeli azosebenzisa ama-maniifples athatha ubude obuguquguqukayo, noma ama-maniifples obude obuguquguqukayo obuqhubekayo, ukuze injini idlale ukusebenza okungcono kuzo zonke izizinda zesivinini.
ukuphakama
Inzuzo eyinhloko ye-plastic intake manifold yizindleko zayo eziphansi nesisindo esilula. Ngaphezu kwalokho, njengoba i-thermal conductivity ye-PA iphansi kune-aluminium, i-nozzle yamafutha kanye nokushisa komoya ongenayo kuphansi. Akukwazi nje ukuthuthukisa ukusebenza kokuqala okushisayo, ukuthuthukisa amandla kanye ne-torque yenjini, kodwa futhi kugweme ukulahlekelwa ukushisa ku-tube ngezinga elithile lapho kuqala amakhaza, kusheshise ukwanda kwezinga lokushisa kwegesi, futhi udonga oluningi lweplastiki bushelelezi, okunganciphisa ukumelana nokugeleza komoya, ngaleyo ndlela kuthuthukise ukusebenza kwenjini.
Mayelana nezindleko, izindleko zempahla ye-plastic intake manifold ngokuyisisekelo ziyefana nalezo zokusetshenziswa kwe-aluminium ngokuphindaphindiwe, futhi i-plastic intake multifold yakheka kanye, ngezinga eliphezulu lokuphasa; Isivuno se-aluminium esetshenziswayo esingenalutho siphansi, izindleko zomshini ziphezulu uma kuqhathaniswa, ngakho-ke izindleko zokukhiqiza ukufakwa kwepulasitiki okuningana zingaphansi ngo-20% -35% kunalezo zokusetshenziswa kwe-aluminium ngokuningi.
Imfuneko yezinto ezibonakalayo
I-1) Ukumelana nokushisa okuphezulu: i-plastic intake manifold ixhunywe ngqo ekhanda le-cylinder yenjini, futhi izinga lokushisa lekhanda le-cylinder lenjini lingafinyelela ku-130 ~ 150 ℃. Ngakho-ke, izinto eziningi zepulasitiki ezithathayo ziyadingeka ukuze zimelane nezinga lokushisa eliphakeme lika-180 ° C.
2) Amandla aphezulu: i-plastic manifold ifakwe enjinini, ukumelana nomthwalo wokudlidliza kwenjini yezimoto, i-throttle kanye ne-sensor inertial force load, i-intake pressure pulsation load, njll., kodwa futhi nokuqinisekisa ukuthi injini ayiqhunyiswa yingcindezi ephezulu. ingcindezi ye-pulsation lapho ukushisa okungavamile kwenzeka.
3) Ukuzinza kwe-Dimensional: Izidingo zokubekezelelana kwe-dimensional zokuxhuma phakathi kwe-multiple intake kanye nenjini ziqinile kakhulu, futhi ukufakwa kwezinzwa nama-actuator ku-manifold kufanele futhi kube nembe kakhulu.
I-4) Ukuzinza kwamakhemikhali: i-plastic intake manifold ithintana ngqo nophethiloli kanye ne-antifreeze coolant lapho isebenza, uphethiloli uyi-solvent enamandla, futhi i-glycol ekupholiseni izophinde ibe nomthelela ekusebenzeni kwepulasitiki, ngakho-ke, ukuzinza kwamakhemikhali epulasitiki. I-take manifold material iphezulu kakhulu futhi idinga ukuhlolwa ngokuqinile.
5) Ukuzinza kokuguga okushisayo; Injini yemoto isebenza ngaphansi kwezinga lokushisa elinzima kakhulu, izinga lokushisa elisebenzayo lishintsha ku-30 ~ 130 ° C, futhi impahla yepulasitiki kufanele ikwazi ukuqinisekisa ukwethembeka kwesikhathi eside kwezinhlobonhlobo.
