Isistimu kaphethiloli yezimoto yakhiwe isistimu yokugcina uphethiloli, isistimu yokujova uphethiloli, kanye nesistimu yamapayipi okuhambisa uphethiloli. Kusukela ekuqaleni kokusebenzisa ipulasitiki ukukhiqiza izingxenye zesistimu kaphethiloli, lokhu sekuyindlela evamile. Ngenxa yesisindo esincane sepulasitiki, ingakwazi ukuhlangabezana nezidingo zezimoto ezingasindi, futhi inganciphisa izindleko. Ngaphezu kwalokho, ipulasitiki ngokwayo inokumelana nokugqwala okuhle kakhulu, okuthuthukisa kakhulu ukumelana nokugqwala kwezingxenye. Ukubumba kungathuthukisa ukusebenza komhlangano okulula kwezingxenye.
I-Car Fuel System
1. Isivalo samafutha
Ikhava yembobo yokujova uphethiloli yemoto ikhava yamafutha. Le ngxenye idinga ukuthi impahla ibe nokumelana nomthelela omuhle futhi akulula ukuba yonakaliswe ngesikhathi sokushintsha nokuwa kwansuku zonke. Ukusebenza kokuvalwa kwengxenye nakho kungcono, okuhlobene nokusebenza kokuvalwa kwe-gasket yokuvala kanye nokuguquguquka kwempahla ngokwayo.
Idizayini yesakhiwo esijwayelekile ukuthi ingxenye engaphezulu yesivalo sikaphethiloli yenziwe ngayoiqinisiwe futhi ishintshiweI-PA6 kanye ne-PA66, kanti ingxenye ephakathi yenziweinayiloni 11 noma inayiloni 12ngokumelana nowoyela okuhle kakhulu, kepha i-polyoxymethylene (POM) isetshenziswa ngokuyisisekelo ukunciphisa izindleko, ingahlangabezana nezidingo
2. I-valve yokuvala amafutha
Ivalvu efakwe ukuvimbela uphethiloli ukuthi ingavuzi iba ivalve yokuvala uphethiloli. Njengoba i-valve yokuvala uphethiloli idinga ukubhakwa ku-100 ° C ngemva kokufakwa kwe-anti-corrosion coating, izinto zokwenza le ngxenye kufanele zimelane nezinga lokushisa lika-130 ° C.
Njengamanje, izinto ezisetshenziswa kakhulu kule ngxenye yiPA6+GFimpahla. Njengamanje, cishe ama-70% amamodeli ajwayelekile asetshenziswaPA6impahla eguquliwengemizimba yama-valve, kanye nokusetshenziswa okungaba ngu-10%.PA66impahlazokukhiqiza. Kwamanye amamodeli asezingeni eliphezulu, amamodeli angama-20% asele akhiqizwa kusetshenziswa i-PBT eqinisiwe ye-glass fiber ephansi.
3. Ithangi lamafutha
Ukuze kuzuzwe umklamo wemoto ongasindi futhi ohlelekile, ithangi likaphethiloli wepulasitiki i-PFT selisetshenziswe kabanzi emhlabeni jikelele. Izici zendawo nosayizi zenza ukubukeka kwamamodeli ezimoto kuhluke kakhulu futhi kuhluke.
Idizayini yethangi likaphethiloli elinezingqimba eziningi yamukela umqondo wokuhlanganisa izendlalelo ezisebenzayo zama-resin ahlukene ne-FAW, okunciphisa izindleko kuyilapho kuhlangatshezwana nezidingo zokungena.PA6impahla ivame ukusetshenziswa njengesendlalelo sesithiyo emathangini kaphethiloli anezingqimba eziningi ngenxa yokumelana kwawo okuhle nokungena kuphethiloli.
4. Ipayipi lamafutha noma ipayipi likaphethiloli
Ipayipi likaphethiloli kufanele limelane nokuguguleka kukaphethiloli, libe nezakhiwo ezinhle zokuthiya ukuze lihlangabezane nezidingo zokudlulisa, futhi limelane namazinga okushisa asuka ku-40°C kuya ku-80°C, likwazi ukumelana nokukhathala okuhle, likwazi ukuguquguquka futhi limelane nesimo sezulu.
Ngaphansi komkhuba wokwehlisa izindleko kanye nokusetshenziswa kwamandla ezimoto, kuvele isisombululo sepayipi lepulasitiki elinezindleko eziphansi zokuhlanganisa nokuhlangabezana nezimo ezingenhla. Ipayipi lepulasitiki liyipayipi elendlalelo elilodwa elenziwe ngezinto ze-PA11. Njengoba ukukhiqizwa kwezimoto emhlabeni wonke kukhuphuka unyaka nonyaka, izinto ze-PA11 azisakwazi ukuhlangabezana nezidingo, ngakhoPA12,PA1010,PA1012,PA612,PA1212kanye neminye imikhiqizo yakhiwe futhi yathuthukiswa ukuze kukhiqizwe amashubhu ongqimba olulodwa.
5. Isixhumi Esisheshayo
Le ngxenye idinga ukumelana nowoyela okuphezulu kanye nokuzinza kwe-dimensional kwento, ngakho-ke isixhumi esisheshayo esenziwePA12 iye yaduma ekusetshenzisweni.
6. Izinsimbi zamafutha
Isitimela sikaphethiloli siyingxenye eyinhloko yendlela yamanje yomjovo we-elekthronikhi enamaphuzu amaningi kanye nomshini wokujova uphethiloli olawulwa nge-elekthronikhi. Izidingo zezinto ezisetshenziswayo ikakhulukazi ukumelana nowoyela, ukumelana nokushisa, ukwahlukanisa izinga lokushisa, ukubekwa uphawu okuhle, ukumelana nokucindezela kanye nokumelana nomthelela. Ikhiqizwa ikakhulukazi kusetshenziswaPA66+GF.
7. Isitsha
I-canister iyisisetshenziswa sokukhangisa segesi kaphethiloli, emunca igesi evuthuluke kuphethiloli ethangini likaphethiloli. Ivamise ukwakhiwa ngekhabhoni ecushiwe, isihlungi esingalukiwe senayiloni kanye nesembozo se-PA66. Ingxenye idinga ukumelana nomthelela, ukushisa nokudlidliza futhi okwamanje ikhiqizwa kusetshenziswaishintshiwe ngokuqinaPA6 nomaPA66.
8. Izithako zamafutha
I-fuel injector iyisisetshenziswa somjovo esilawulwa nge-elekthronikhi esijova uphethiloli usuka endaweni yokungena eduze kwekhanda lesilinda ngezikhathi ezithile. Impahla yomzimba oyinhlokoPA66+GF. Phakathi kwazo, uhlaka lwekhoyili lwe-electromagnet ludinga ukusetshenziswaInayiloni eqinisiwe yengilazi engavimbeli ukushisaimikhiqizo, ngokuvamilePA6T,PA9t, futhiPA46.
