Ii-injectors zepetroli - "Iimimoya zepetroli" zenjini
Kwinkqubo entsonkothileyo yenjini yemoto, i-fuel injector idlala indima ebalulekileyo njenge "fuel spirit", enye yezona zinto ziphambili kwiinjini ze-electronic fuel injection. Ngokuyintloko, yivalvu elula ye-electromagnetic. Xa i-electromagnetic coil inikwe amandla, amandla okufunxa avelisiweyo aya kuphakamisa ivalvu yenaliti, ivule i-nozzle, kwaye ipetroli iya kutshizwa ngesantya esiphezulu ngesithuba esiphakathi kwentloko yenaliti kunye ne-nozzle, yenze imeko efana ne-mist, ethi emva koko ixubane nomoya ukuze kufezekiswe iimeko ezilungileyo zokutsha kwenjini.
Ukuchaneka kokusebenza kwe-fuel injector kumisela ngokuthe ngqo ukusebenza kwenjini. Phantsi kwemiyalelo echanekileyo yeyunithi yokulawula ye-elektroniki yenjini (ECU), itshiza ipetroli kwisilinda ngamaxesha athile kwaye ngobuninzi obumiselweyo ngokwemeko yokusebenza kwenjini. Kukho iintlobo ezimbini eziphambili zeendlela zokutshiza ipetroli: enye yi-intake manifold injection, apho i-fuel injector ikwi-intake manifold kwaye itshiza ipetroli kwi-intake manifold ukuze ixubane nomoya ngaphambi kokuba ingene kwisilinda; enye yi-direct injection kwi-cylinder, apho i-fuel injector ingena ngqo ngaphakathi kwesilinda kwaye itshiza ipetroli ngoxinzelelo oluphezulu kwisilinda. Nangona ezi ndlela zimbini zinemigaqo efanayo yokwakha, i-direct injection fuel injector kufuneka imelane noxinzelelo oluphezulu, oluqhele ukuba phakathi kweekhilogram ezingama-24 ukuya kuma-200, ngelixa uxinzelelo lwe-intake manifold injection ngokubanzi luphakathi kweekhilogram ezi-2 nezi-8.
Ukujova ipetroli ngokuchanekileyo sisiqinisekiso sokusebenza kakuhle kwenjini. I-fuel injector ilawula ubungakanani be-fuel injection kunye nexesha ukuqinisekisa ukuba injini inokufumana umlinganiselo ofanelekileyo womoya-fuel phantsi kweemeko ezahlukeneyo zokusebenza, ngaloo ndlela ifezekisa ibhalansi engcono kakhulu yokukhupha amandla, ukonga ipetroli, kunye nokukhutshwa komoya. Kunokuthiwa imeko yokusebenza kwe-fuel injector ichaphazela ngokuthe ngqo ukusebenza kwamandla enjini, inqanaba lokusetyenziswa kwepetroli, kunye nomgangatho wokukhutshwa komoya.
Ukungasebenzi kakuhle kwe-injector yepetroli - "Umbulali ongabonakaliyo" wenjini
Njengoko isantya semoto sisanda kwaye imeko-bume yokusetyenziswa itshintsha, ii-fuel injectors nazo zinokudibana nokusilela okuhlukeneyo, zibe "ngumbulali ongabonakaliyo" ochaphazela ukusebenza kwenjini. Izizathu zokusilela kwe-fuel injector ziyinkimbinkimbi kwaye zinxulumene kakhulu nomgangatho we-fuel, imikhwa yokusetyenziswa, kunye nokuguga kwenxalenye. Iintsini, ukungcola kwi-fuel, kunye nothuli oluziswa ngexesha lokugcina nokuthuthwa ziya kuqokelelana ngokuhamba kwexesha kwindawo ye-fuel injector, zenze iidiphozithi. Ezi diphozithi, xa zishushu, ziya kuba ziidiphozithi zekhabhoni eqinileyo, zivale ivalvu yenaliti kunye nemingxunya yevalvu ye-fuel injector. Ukongeza, ukuxinana kwezithuthi ezidolophini kuhlala kubangela ukuba izithuthi zisebenze ngesantya esiphantsi kwaye zingasebenzi, nto leyo eya kukhawulezisa ukwakheka kunye nokuqokelelwa kweediphozithi.
Ukungasebenzi kakuhle kwe-fuel injector kuya kubangela uthotho lweempawu ezicacileyo, nto leyo eya kwazisa i-车主 ukuba inikele ingqalelo. Uphawu lokuqala kukuncipha kwamandla kunye nobunzima bokukhawulezisa. Xa i-fuel injector ivalekile kwaye umthamo we-fuel injection awanelanga, injini ayinakufumana amafutha aneleyo, kwaye amandla aya kuncipha kakhulu ngokwemvelo, ingakumbi xa ikhawuleza ngokukhawuleza, kuya kubakho ukulibaziseka okubonakalayo. Uphawu lwesibini kukunyuka okungaqhelekanga kokusetyenziswa kwe-fuel. Ukungasebenzi kakuhle kwe-fuel atomization kuya kubangela ukutsha kwe-fuel okungaphelelanga, kwaye injini iya kwandisa umthamo we-fuel injection ukugcina amandla, nto leyo ekhokelela ekwandeni okukhulu kokusetyenziswa kwe-fuel.
Ukungenzi nto kunye nokungcangcazela okungalinganiyo nazo ziimpawu eziqhelekileyo. Ukuvaleka kwe-fuel injector okanye i-atomization embi kuya kubangela ukusasazwa kwamafutha okungalinganiyo kwi-cylinder, okwandisa umahluko kumsebenzi we-cylinder, kwaye nokuba i-ECU yenza uhlengahlengiso, ayinakuyilungisa ngokupheleleyo, ngaloo ndlela ibangele ukuguquguquka kwesantya sokungenzi nto kunye nokungcangcazela kwesithuthi. Ukongeza, ukukhutshwa okugqithisileyo komoya ophumayo, ubunzima ekuqaliseni okubandayo, kunye nezibane zempazamo zenjini ezikhanyayo nazo zinokuba ziimpawu zokungaphumeleli kwe-fuel injector. Ukungaphumeleli okukhulu kwe-fuel injector kunokukhokelela ekunqongophaleni kwe-injini cylinder, ukucima injini ngequbuliso, kunye nezinye iingxaki ezinkulu ezichaphazela ukhuseleko lokuqhuba.
Impendulo kunye nokuthintela ukungasebenzi kakuhle kwe-fuel injector
Ukujongana nokusilela kwe-fuel injector, iimpendulo ezifike ngexesha nezisebenzayo zibalulekile. Xa kuvela ezi mpawu zingasentla, umnini angasebenzisa inkqubo yokuxilonga ekwibhodi (i-OBD) kuqala ukuze afunde iikhowudi zempazamo ukuze amisele unobangela wokungaphumeleli. Kwiingxaki ezincinci ze-fuel injector, izongezo ze-fuel eziqulethe izinto ze-PEA zingasetyenziselwa ukucoca. Ngokubanzi, ukuzisebenzisa izihlandlo ezi-2-3 kunokunyibilikisa ngempumelelo kwaye kususe iidipozithi zekhabhoni, ukubuyisela i-fuel injector ekusebenzeni okuqhelekileyo.
Ukuba ingxaki inkulu, njengevalvu yenaliti ebambekileyo kwi-injector yepetroli okanye ikhoyili etshisiweyo, kuyimfuneko ukuya kwivenkile yokulungisa yobungcali ukuze ilungiswe okanye itshintshwe ngoko nangoko. Ngexesha lenkqubo yokulungisa, iingcali zobungcali ziya kusebenzisa izixhobo zobungcali ukucoca, ukuvavanya nokulungisa i-injector yepetroli ukuqinisekisa ukuba ibuyela kwisimo sayo esiqhelekileyo.
Ukuthintela ukungasebenzi kakuhle kwe-injector yepetroli kubaluleke kakhulu ekugcinweni kwemihla ngemihla. Kucetyiswa ukuba abanini beemoto benze uhlolo lwe-injector yepetroli kunye nokucoca kanye kwiikhilomitha ezingama-2-3 amawaka. Ukuba imoto isebenzisa ipetroli esemgangathweni kwaye igcinwe kakuhle, ixesha lingandiswa liye kwiikhilomitha ezingama-4-6 amawaka. Kwangaxeshanye, khetha isikhululo sepetroli esithembekileyo ukuze wongeze ipetroli esemgangathweni ophezulu ukuze uphephe ukusebenzisa ipetroli engaphantsi, enokunciphisa umonakalo kwi-injector yepetroli obangelwa bukungcola kunye neentsini kwipetroli. Ukongeza, zama ukuphepha ukungenzi nto ixesha elide kwaye unciphise ukuqala rhoqo kunye nokuma kwiimeko zezithuthi zasezidolophini, okunokucothisa ngempumelelo ukwakheka kwediphozithi zekhabhoni kwi-injector yepetroli.
Ngamafutshane, i-fuel injector yinxalenye ebalulekileyo yenjini, kwaye umsebenzi wayo awunakutshintshwa. Ukuqonda umgaqo wokusebenza kunye neempawu zempazamo ze-fuel injector, kunye nokukwazi ukuphendula ngokuchanekileyo kunye neendlela zokuthintela, kunokunceda abanini bemoto ukuba babone kwaye basombulule iingxaki ngexesha, baqinisekise ukuba injini ihlala ikwimeko engcono yokusebenza kwaye inike ukhuseleko oluthembekileyo lokusebenza kwamandla esithuthi kunye nokhuseleko lokuqhuba.
