Iphaneli ye-hood yenjini: Umkhuseli wenjini oguquguqukayo
Iphaneli ye-engine hood, ebonakala ngathi ayibalulekanga kangako emotweni, idlala indima ebalulekileyo kwaye isiqinisekiso esibalulekileyo sokusebenza kwenjini ngokuqhelekileyo.
Okokuqala, inomsebenzi wokukhusela ngokwasemzimbeni. Ifana "nesikrweqe" senjini, esikwaziyo ukuthintela ngokufanelekileyo inkunkuma ebhabhayo, uthuli, amanzi emvula kunye nezinye izinto zangaphandle ngexesha lokuqhuba, ukuthintela ukuba zingadibani ngqo nezinto eziphambili kunye nemibhobho ejikelezileyo yenjini, ngaloo ndlela kunciphisa umngcipheko wokubola kwenxalenye, ukuguguleka kwemibhobho kunye nokujikeleza okufutshane kwesekethe. Kwimeko yokungqubana okuncinci, ezinye iiphaneli zehood zinokuthintela amandla ombane ngokusebenzisa ukuguqulwa kwazo, ukunciphisa amathuba okonakala kwezinto eziphambili zenjini.
Okwesibini, ngokubhekiselele kulawulo lwengxolo, iphaneli ye-hood yenjini nayo idlala indima ebalulekileyo. Uninzi lweephaneli ze-hood zizaliswe ngaphakathi zizinto zekotoni ezifunxa isandi, ezinokufunxa kwaye zibonakalise ingxolo yoomatshini eveliswa kukusebenza kwenjini. Ngokwesiqhelo, oku kunokunciphisa ingxolo yangaphakathi ngama-20%-30%. Ekuqhubeni ngesantya esiphezulu okanye xa injini isebenza phantsi komthwalo omkhulu, esi siphumo sokunciphisa ingxolo sibaluleke ngakumbi, siphucula kakhulu intuthuzelo yokuqhuba nokukhwela.
Ukuphucula i-aerodynamics kukwangomnye wemisebenzi yayo ephambili. Imiphezulu yeephaneli zokuqala ze-hood zefektri-injini idla ngokuba nee-arcs ezilungelelanisiweyo, eziye zaqinisekiswa ngovavanyo lwe-wind tunnel ukukhokela ukuhamba komoya ngaphezulu kwe-injini ngokutyibilikayo, kunciphisa ukumelana nomoya. Idatha ibonisa ukuba uyilo lwe-hood oluphuculweyo lunokunciphisa i-coefficient yokumelana nomoya yesithuthi nge-0.01-0.03, okuhambelana nokonga ukusetyenziswa kwepetroli malunga ne-0.2-0.4 yeelitha kwiikhilomitha ezili-100, okunciphisa ngempumelelo iindleko zepetroli kwixesha elide.
Ngokuphathelele ibhalansi yolawulo lobushushu, iphaneli ye-hood yenjini nayo ayibalulekanga. Ezinye iiphaneli ze-hood zeemodeli zisebenzisa uyilo oluneembobo okanye imijelo yomoya egciniweyo, kunye nenkqubo yokupholisa yegumbi lenjini, zinokwenza ubushushu busasazeke ngokulinganayo. Kwangaxeshanye, inokuthintela umoya obandayo ekuchaphazeleni injini ngokuthe ngqo, incede injini ifikelele kubushushu obuqhelekileyo bokusebenza ngokukhawuleza ngexesha lokuqala okubandayo, inciphise ukusetyenziswa kwepetroli kunye nokukhutshwa komoya ngexesha lokuqala okubandayo.
Ukongeza, umsebenzi wokukhusela ukhuseleko awunakutyeshelwa. Iiphaneli ze-hood zenjini yemoto zanamhlanje zenziwe kakhulu ngezinto ezithintela umlilo. Xa kukho iimeko ezingxamisekileyo ezifana nokuvuza kweoyile yenjini kunye nomlilo kwindawo yenjini, zinokucothisa ukusasazeka komlilo kwaye zinike umnini ixesha elingakumbi lokujongana nongxamiseko. Ezinye iimodeli eziphezulu nazo zinemisebenzi yokukhusela abahambi ngeenyawo. Xa imoto ingqubana nomntu ohamba ngeenyawo, iphaneli ye-hood iya kuvela ngokuzenzekelayo, yenze indawo yokukhusela, inciphise ubunzima bokwenzakala kwabahamba ngeenyawo. Ngaphezu koko, inokukhusela imibhobho entsonkothileyo kunye neentambo kwindawo yenjini, yenze indawo ibukeke icocekile kwaye ihlelekile, iququzelele ukuhlolwa nokugcinwa kwemihla ngemihla.
Iimpazamo eziqhelekileyo kunye nezisombululo zeepaneli ze-hood yenjini
Nangona iiphaneli ze-engine hood zinemisebenzi emininzi, ngexesha lokusetyenziswa ixesha elide, ezinye iimpazamo zinokwenzeka, nto leyo edinga ukuba umniniyo azibone aze aziphathe ngexesha elifanelekileyo.
Ukushukuma kwephaneli yeHood yenye yezona mpazamo zixhaphakileyo. Ukutsha kwenjini kakubi yimbangela ebalulekileyo yale ngxaki. Iimpazamo kwinkqubo yokutsha, ezinje ngeekhoyili zokutsha ezimoshakeleyo, iiplagi zentlantsi, ii-fuel injectors ezingasebenzi kakuhle okanye iisekethe zazo, kunye noxinzelelo oluphantsi lwesilinda, zonke ezi zinto zinokukhokelela ekusebenzeni kwenjini okungazinziyo kwaye emva koko zibangele ukuba iphaneli yehood ishukume. Ukwaluphala okanye ukukhululeka kweglue yenyawo yenjini kunokudlulisela ngokuthe ngqo ukushukuma kwenjini kwiphaneli yehood. Ukongeza, iidiphozithi zekhabhoni ezigqithisileyo kwiisilinda, ukusilela kwenkqubo yepetroli, i-throttle okanye izihluzi zomoya ezimdaka, ukusebenza okungaqhelekanga kweplagi yentlantsi, ukulungiswa okungafanelekanga okanye ukukhululeka kwephedi yerabha phantsi kwehood yenjini, kunye nezinye izinto zonke zinokubangela ukuba iphaneli yehood ishukume. Ukujongana nale micimbi, umnini kufuneka enze uphando olucokisekileyo, njengokulungisa iimpazamo zenkqubo yokutsha kunye ne-fuel injection, ukutshintsha iglue yeenyawo zenjini endala, ukucoca iidiphozithi zekhabhoni, ukucoca i-throttle kunye nesihluzi somoya, ukutshintsha iiplagi zentlantsi, njl.
Ukungavaleki kakuhle kwephaneli ye-hood nako kuyingxaki ekhathaza abanini abaninzi. Iindlela zokutshixa ezigugileyo okanye ezitshintshiweyo zezona zinto zixhaphakileyo. Ukuvulwa nokuvalwa kwexesha elide kwephaneli ye-hood kuya kubangela ukuba izinto zesinyithi zendlela yokutshixa ziguge kwaye izikrufu zokulungisa zikhululeke. Ngeli xesha, izikrufu kufuneka ziqiniswe okanye indlela yokutshixa itshintshelwe. Ukungaphumeleli kwentonga ye-hydraulic kuya kubangela ukuba iphaneli ye-hood iwe kwaye ingatshixeki, kwaye kufuneka itshintshwe ngokukhawuleza. Imicimbi efana nocingo lokutsala i-lock, ukuguquka kwepleyiti yokugquma, intwasahlobo yangaphakathi yokuphuka kwe-lock, kunye nokuguga kwe-sealing strip nako kunokubangela ukuba ipleyiti yokugquma ingangeni kakuhle. Izisombululo ezifanelekileyo ziquka ukucoca okanye ukutshintsha i-pull wire, ukulungisa ipleyiti yokugquma egugileyo nge-sheet metal, ukutshintsha intwasahlobo yangaphakathi ye-lock, kunye nokutshintsha i-sealing strip, njl.
Ukungahambelani kwepleyiti yokugquma nako kuchaphazela ukusetyenziswa kwezithuthi. Iingxaki ezinje ngocingo lokutsala lwe-hood olungabuyeli kwindawo yalo yokuqala, ukuguquka kwesitshixo, ukuguquka kwepleyiti yokugquma ngenxa yokungqubana, iimpazamo zemveliso kunye nokuhlanganiswa, ukungcangcazela kwexesha elide kunye namandla abangela ukukhululeka kunye nokuguquka kwesitshixo, umonakalo ekubambeni kwesitshixo, ukuguga kwe-rain shield, kunye nezikrufu ezikhululekileyo, zonke ezi zinto zinokubangela ukuba ipleyiti yokugquma ingahambelani. Ukungahambelani okuncinci kunokuhlengahlengiswa nguwe. Vula i-hood, khulula izikrufu ezidibanisa umzimba, ulungelelanise kwindawo efanelekileyo, uze uziqinise; ukuba ukuguquguquka kukhulu okanye izinto zonakele, kufuneka uncedo lokulungisa oluyingcali.
Ukongeza, kunokubakho iingxaki ezifana nepleyiti yokugquma etsibatsibayo, njengokusilela ukuvala ngokupheleleyo, okubangela ukuba isibane sesilumkiso sivuleke, izinto zasemzini zibambeke, ucingo lokutsala luqine kakhulu, ukuguguleka kwe-lock catch, ukungasebenzi kakuhle kweswitshi, ukwaphuka okanye ukuqhekeka kwe-pull wire, ukuthambisa okwaneleyo kwe-lock tooth spring, njl. Xa udibana nezi ngxaki, lungisa kwakhona i-closure, susa izinto zasemzini, lungisa uxinzelelo lwe-pull wire, tshintsha i-lock catch, thumela ukuba kulungiswe i-switch, tshintsha i-pull wire, yongeza i-oyile yokuthambisa, njl. Kwiingxaki zomzimba, kucetyiswa iinkonzo zokulungisa zobungcali.
