I-throttle: "I-Power Valve" yeNjini
I-throttle yaziwa ngokuba yi-"throat" yenjini yemoto. Iqhagamshela kwi-air filter ephezulu kunye nesilinda yenjini ezantsi. Yivalvu elawulwayo engundoqo elawula ukungena komoya enjinini. Umsebenzi wayo ophambili kukulawula ngokuchanekileyo umthamo wokungenisa ngokulungelelanisa iqondo lokuvula kwayo, ngaloo ndlela ihambelana neemeko zokusebenza ezahlukeneyo zenjini kunye nemfuno yamandla.
Xa umqhubi enyathela i-accelerator pedal, ukuvulwa kwe-throttle kuyanda, okuvumela umoya omninzi ukuba ungene kwisilinda, uxutywe nepetroli ukwenza umxube ovuthayo, oya kuthi emva koko uvuthelwe kwaye ukhuphe amandla amaninzi okuqhubela imoto phambili. Xa i-accelerator ikhululwa, ukuvulwa kwe-throttle kuyancipha, kunciphisa umthamo wokungenisa kwaye kubangele ukuba isantya senjini sehle. Kwimo yokungenzi nto, i-throttle igcina ukuvulwa okuncinci ukuze inike umthamo wokungenisa ozinzileyo kwinjini, igcina isantya sokungenzi nto esizinzileyo, nokuba i-air conditioning, i-steering assist, kunye neminye imithwalo ivuliwe, kwaye ilungisa ngokuzenzekelayo umthamo wokungenisa ukuqinisekisa ukuba injini isebenza ngokuqhelekileyo.
Kwangaxeshanye, i-throttle isebenza ngokusondeleyo neyunithi yolawulo lwe-elektroniki yenjini (ECU) ukuze kufezekiswe ulawulo oluchanekileyo lomlinganiselo womoya-fuel. I-ECU isebenzisa idatha yomthamo wokungenisa ovela kwi-throttle ukubala umthamo ofanelekileyo wokufaka ipetroli, ivumela umoya kunye namafutha ukuba axubane ngomlinganiselo ofanelekileyo, onokunyusa amandla okukhupha ngelixa kunciphisa ukusetyenziswa kwepetroli kwaye kuncitshiswe ukukhutshwa komoya. Kwezinye iimodeli, i-throttle ekwindawo evulekileyo ngokupheleleyo inokunceda ekususeni iidipozithi zekhabhoni kwisilinda ngesantya esiphezulu sokungenisa umoya kunye nobushushu bokutsha, yandisa ubomi benjini.
Ukusombulula iingxaki: "Uphawu oluNgxamisekileyo" lweThrottle
Nangona i-throttle incinci ngobukhulu, isenokungasebenzi kakuhle ngenxa ye-carbon deposits, ukuguguleka, njl.njl., nto leyo enokuchaphazela ukusebenza kwesithuthi. Abanini banokubamba "uphawu olungxamisekileyo" lwe-throttle ngezi mpawu zilandelayo ziqhelekileyo.
Ukungenzi nto ngendlela engaqhelekanga yeyona nto ixhaphakileyo xa i-throttle ingasebenzi. Xa imoto imile kwaye ingasebenzi, i-tachometer pointer inokutsiba ngokuphindaphindiweyo phakathi komgama we-800-1200 rpm, ihamba nokushukuma komzimba okukhulu, ingakumbi xa uqala imoto phantsi kweemeko ezibandayo. Oku kungenxa yokuba i-carbon deposits ibangela ukuba i-throttle ibambeke, okwenza kube nzima ukulawula umthamo wokungenisa ngokuzinzileyo, kwaye i-ECU inokulungisa kuphela ukufakwa kwepetroli ukuze iqhubeke nokusebenza.
Ukukhawulezisa okucothayo kunye namandla angonelanga ziimpawu eziqhelekileyo. Emva kokunyathela i-accelerator, imoto ikhawuleza kancinci, kwaye injini iphendula kancinci xa i-accelerator icinezelwe ngamandla. Xa idlula okanye inyuka iinduli, amandla "athambile kwaye abuthathaka". Oku kungenxa yokuba i-throttle ayinakukwazi ukulungisa inqanaba layo lokuvula ngokuphendula kwisignali ye-accelerator ngexesha, nto leyo ebangela ukuba umthamo wokungenisa unganeli kwaye kuncitshiswe ukusebenza kakuhle kokutshisa amafutha.
Ukongeza, ukungaphumeleli kwe-throttle kunokubangela ukwanda okukhulu kokusetyenziswa kwepetroli. Ukungalingani komlinganiselo we-air-fuel okubangelwa kukungaphumeleli kuya kubangela ukuba injini yonyuse ukufakwa kwepetroli ukuze igcine amandla, kwaye umnini uya kuqaphela ukuba ngemikhwa efanayo yokuqhuba, isantya sokugcwalisa amafutha siyanda kakhulu. Kwiimeko ezinzima, isibane se-fault senjini okanye isibane se-EPC kwideshibhodi siya kukhanyisa, esisisilumkiso esithunyelwa yi-ECU emva kokubona imiqondiso ye-throttle engaqhelekanga. Ngeli xesha, kufuneka kusetyenziswe isixhobo sokuxilonga ukufunda ikhowudi ye-fault ukuchonga ingxaki ethile.
Ukuba kukho iidipozithi zekhabhoni ezininzi okanye ukuvaleka okukhulu kwe-throttle, kunokubangela ubunzima ekuqaliseni okubandayo, okanye ukucima injini okungalindelekanga ngexesha lokuqhuba, okubangela ingozi yokhuseleko.
Ukugcinwa Kwemihla ngemihla: Ukugcina "Umqala" Ungaphazanyiswa
Ukuze kuthintelwe ukungaphumeleli kwe-throttle okuchaphazela ukusebenza kwesithuthi, ukugcinwa kwemihla ngemihla kubalulekile. Kucetyiswa ukuba ujonge imeko ye-throttle kanye rhoqo kwiikhilomitha ezingama-2-3 amawaka kwaye ucoce iidipozithi zekhabhoni ngexesha. Xa ucoca, sebenzisa isicoci esikhethekileyo. Ukuba umnini akaqhelananga nolwakhiwo lwemoto, kungcono ukuba iqhutywe yingcali ukuze kuthintelwe ukonakalisa izinto ze-throttle.
Kwangaxeshanye, ukusebenzisa ipetroli esemgangathweni ophezulu kunye nokutshintsha isihluzi somoya rhoqo kunokunciphisa ukungcola ekungeneni kwi-throttle, kunciphise ukwakheka kweediphozithi zekhabhoni. Ezinye iimodeli ezineenkqubo zokuzicoca ezikrelekrele ze-throttle zinezinga lokusilela eliphantsi ngama-67% xa kuthelekiswa nee-throttle zendabuko. Abanini banokunika ingqalelo ekhethekileyo kolu qwalaselo xa bekhetha imoto.
