Iphaneli ye-hood yenjini: Umqaphi wenjini oguquguqukayo
Iphaneli ye-engine hood, ebonakala ingeyona ingxenye ebalulekile emotweni, empeleni idlala izindima eziningi ezibalulekile futhi iyisiqinisekiso esibalulekile sokusebenza okuvamile kwenjini.
Okokuqala, inomsebenzi wokuvikela ngokomzimba. Ifana "nezembatho zempi" zenjini, ezikwazi ukuvimba ngempumelelo imfucumfucu endizayo, uthuli, amanzi emvula nezinye izinto zangaphandle ngesikhathi sokushayela, zivimbele ukuthintana ngqo nezingxenye eziyinhloko kanye namapayipi azungezile enjini, ngaleyo ndlela kuncishiswe izingozi zokugqwala kwezingxenye, ukuguguleka kwepayipi ngisho nokujikeleza kwesekethe okufushane. Uma kwenzeka ukushayisana okuncane, amanye amaphaneli e-hood angavimbela amandla okushaya ngokuguquguquka kwawo, anciphise amathuba okulimala kwezingxenye eziyinhloko zenjini.
Okwesibili, maqondana nokulawula umsindo, iphaneli ye-hood yenjini nayo idlala indima ebalulekile. Amaphaneli amaningi e-hood agcwele ngaphakathi izinto zikakotini ezimunca umsindo, ezingamunca futhi zibonise umsindo womshini okhiqizwa ukusebenza kwenjini. Ngokuvamile, lokhu kunganciphisa umsindo wangaphakathi ngo-20%-30%. Ekushayeleni ngesivinini esikhulu noma lapho injini isebenza ngaphansi komthwalo omkhulu, lo mphumela wokunciphisa umsindo ubaluleke kakhulu, okuthuthukisa kakhulu induduzo yokushayela nokugibela.
Ukuthuthukisa i-aerodynamics nakho kungomunye wemisebenzi yayo eyinhloko. Ubuso bamaphaneli okuqala e-hood yefektri-injini buvame ukuba nama-arcs alula, aqinisekiswe ngokuhlolwa kwemigudu yomoya ukuze kuqondiswe ukuhamba komoya ngaphezu kwegumbi lenjini ngokushelela, kunciphisa ukumelana nomoya. Idatha ikhombisa ukuthi ukwakheka kwe-hood okulungiselelwe kunganciphisa i-coefficient yokumelana nomoya yemoto ngo-0.01-0.03, okuhambisana nokonga ukusetshenziswa kukaphethiloli okungaba amalitha angu-0.2-0.4 ngamakhilomitha ayi-100, kunciphisa ngempumelelo izindleko zikaphethiloli esikhathini eside.
Ngokuphathelene nebhalansi yokuphathwa kokushisa, iphaneli ye-hood yenjini nayo ibalulekile. Amanye amaphaneli e-hood amamodeli asebenzisa imiklamo enezimbobo noma iziteshi zokungenisa umoya ezigciniwe, kuhlanganiswe nohlelo lokupholisa lwegumbi lenjini, kungenza ukushisa kuhlakazeke ngokulinganayo. Ngesikhathi esifanayo, kungavimbela umoya obandayo ukuthi ungayithinti ngqo injini, kusize injini ifinyelele izinga lokushisa lokusebenza elijwayelekile ngokushesha ngesikhathi sokuqala okubandayo, kunciphise ukusetshenziswa kukaphethiloli kanye nokukhishwa komoya ngesikhathi sokuqala okubandayo.
Ngaphezu kwalokho, umsebenzi wokuvikela ukuphepha awunakushaywa indiva. Amaphaneli e-hood yenjini yemoto yesimanje akhiwe kakhulu ngezinto ezivimbela ilangabi. Uma kunezimo eziphuthumayo njengokuvuza kwamafutha enjini kanye nomlilo endaweni yenjini, anganciphisa ukusabalala komlilo futhi anikeze umnikazi isikhathi esengeziwe sokusingatha isimo esiphuthumayo. Amanye amamodeli aphezulu nawo anemisebenzi yokuvikela abahamba ngezinyawo. Lapho imoto ishayisana nomuntu ohamba ngezinyawo, iphaneli ye-hood izovela ngokuzenzakalelayo, yakhe isikhala se-buffer, inciphise ubunzima bokulimala kwabahamba ngezinyawo. Ngaphezu kwalokho, ingavikela amapayipi ayinkimbinkimbi kanye nezintambo endaweni yenjini, yenze indawo ibukeke icocekile futhi ihlelekile, ilula ukuhlolwa nokugcinwa kwansuku zonke.
Amaphutha avamile kanye nezixazululo zamaphaneli e-hood yenjini
Nakuba amaphaneli e-hood enjini enemisebenzi eminingi, ngesikhathi sokusetshenziswa isikhathi eside, kungase kube namaphutha athile, adinga umnikazi ukuthi awabone futhi awaphathe ngesikhathi.
Ukuqhaqhazela kwephaneli ye-hood kungenye yamaphutha avame kakhulu. Ukusha kwenjini kabi kuyimbangela ebalulekile yale nkinga. Amaphutha ohlelweni lokushisa, njengamakhoyili okushisa owonakele, ama-spark plug, ama-fuel injector angasebenzi kahle noma amasekethe awo, kanye nomfutho ophansi wesilinda, konke kungaholela ekusebenzeni kwenjini okungazinzile futhi kamuva kubangele ukuthi iphaneli ye-hood inyakaze. Ukuguga noma ukukhululeka kweglue ye-foot yenjini nakho kungadlulisela ngqo ukuqhaqhazela kwenjini kuphaneli ye-hood. Ngaphezu kwalokho, amadiphozithi ekhabhoni amaningi kumasilinda, ukwehluleka kwesistimu kaphethiloli, i-throttle noma izihlungi zomoya ezingcolile, ukusebenza okungajwayelekile kwe-spark plug, ukulungiswa okungafanele noma ukukhululeka kwephedi yerabha ngaphansi kwe-hood yenjini, nezinye izici kungabangela ukuthi iphaneli ye-hood inyakaze. Ukuze kuxazululwe lezi zinkinga, umnikazi udinga ukwenza uphenyo olunzulu, njengokulungisa amaphutha esistimu yokushisa kanye neyokufaka uphethiloli, ukufaka esikhundleni seglue ye-foot yenjini endala, ukuhlanza amadiphozithi ekhabhoni, ukuhlanza i-throttle kanye nesihlungi somoya, ukufaka esikhundleni sama-spark plug, njll.
Ukungavali kahle kwephaneli ye-hood nakho kuyinkinga ekhathaza abanikazi abaningi. Izindlela zokukhiya ezigugile noma ezishintshiwe ziyizimbangela ezivamile. Ukuvulwa nokuvalwa kwesikhathi eside kwephaneli ye-hood kuzokwenza izingxenye zensimbi zendlela yokukhiya ziguge kanye nezikulufo zokulungisa zikhululeke. Ngalesi sikhathi, izikulufo zidinga ukuqina noma indlela yokukhiya ishintshwe. Ukwehluleka kwenduku ye-hydraulic kuzokwenza iphaneli ye-hood iwe futhi yehluleke ukukhiya, futhi idinga ukushintshwa ngokushesha. Izinkinga ezifana nentambo yokudonsa i-lock, ukuguquguquka kwepuleti lesembozo, intwasahlobo yangaphakathi ye-lock ephukayo, kanye nokuguga kwe-sealing strip nakho kungabangela ukuthi ipuleti lesembozo lingangeni kahle. Izixazululo ezifanayo zifaka phakathi ukuhlanza noma ukufaka esikhundleni sentambo yokudonsa, ukulungisa ipuleti lesembozo eligugile ngensimbi yeshidi, ukufaka esikhundleni sentwasahlobo yangaphakathi ye-lock, nokufaka esikhundleni se-sealing strip, njll.
Ukungahambelani kwepuleti lesimbozo nakho kuthinta ukusetshenziswa kwezimoto. Izinkinga ezifana nocingo lokudonsa lwe-hood olungabuyeli endaweni yalo yokuqala, ukuguquguquka kwe-lock, ukuguquguquka kwepuleti lesimbozo ngenxa yokushayisana, amaphutha okukhiqiza nokuhlanganisa, ukudlidliza kwesikhathi eside kanye namandla okubangela ukukhululeka nokuguquguquka kwe-lock, umonakalo wokubamba i-lock, ukuguga kwesivikelo semvula, kanye nezikulufo ezikhululekile, konke kungaholela ekutheni ipuleti lesimbozo lingahambelani. Ukungahambelani okuncane kungalungiswa nguwe. Vula i-hood, khulula izikulufo ezixhumanisa umzimba, ulungise endaweni efanele, bese uziqinisa; uma ukuguquguquka kukhulu noma izingxenye zonakele, kudingeka usizo lochwepheshe lokulungisa.
Ngaphezu kwalokho, kungase kube nezinkinga ezifana nepuleti lesembozo eligxumayo, njengokwehluleka ukuvala ngokuphelele, okubangela ukukhanya kwesixwayiso ukuthi kuvuleke, izinto zakwamanye amazwe zibhajwe, ucingo lokudonsa luqine kakhulu, ukuguguleka kokubamba ilokhi, ukungasebenzi kahle kweswishi, ukuphuka noma ukuhlukana kocingo lokudonsa, ukugcotshwa okunganele kwentwasahlobo yamazinyo okukhiya, njll. Uma uhlangabezana nalezi zinkinga, lungisa kabusha ukuvala, susa izinto zakwamanye amazwe, lungisa ukucindezeleka kocingo lokudonsa, shintsha ukubamba ilokhi, thumela ukuze kulungiswe iswishi, shintsha ucingo lokudonsa, engeza uwoyela wokugcoba, njll. Uma kunezinkinga zomzimba, kunconywa izinsizakalo zokulungisa zobungcweti.
