Kuyini i-throttle yemoto
I-throttle valve iyi-valve elawula umoya ongenayo injini futhi ilungisa amandla okukhipha kanye nokusetshenziswa kukaphethiloli kwenjini ngokulungisa ukugeleza komoya.
Amavalvu e-throttle ezimoto, aziwa nangokuthi amavalvu e-throttle noma amavalvu e-gas pedal, ayizingxenye ezibalulekile ezinhlelweni zokuphathwa kwenjini yezimoto. Umsebenzi wawo oyinhloko ukulawula ukuphuma kwamandla kanye nokusetshenziswa kukaphethiloli kwenjini ngokulawula ukugeleza komoya enjinini, okuthinta inani lokufakwa kukaphethiloli.
Umgomo wokusebenza we-valve ye-throttle yemoto
Ukulawula ukugeleza komoya: Uma umshayeli ecindezela phansi i-pedal yegesi, izinzwa ziguqula isenzo sibe isignali kagesi edluliselwa kwi-electronic control Unit (ECU). I-ECU ilungisa ukuvulwa kwe-throttle valve ngesikhathi sangempela ngokuya ngesimo se-throttle, isimo senjini nezinye izici, ngaleyo ndlela ilawula inani lomoya ongena enjinini.
Ukulawulwa kokukhishwa kwamandla: Ushintsho ekuvulekeni kwevalvu ye-throttle luthinta ngqo ivolumu yokungenisa yenjini, okuthi futhi kuthinte inani lokufakwa kukaphethiloli kanye nokusebenza kahle kokushisa. Ukwandisa ukuvulwa kuthuthukisa ukusebenza kwenjini, kuyilapho ukunciphisa ukuvulwa kusiza ukunciphisa ukusetshenziswa kukaphethiloli.
Ukulawulwa Kwemvelo Nokukhishwa Kwegesi: Ngokulawula ngokunembile isilinganiso somoya nophethiloli, ama-valve e-throttle asiza ekufezeni inqubo yokushisa esebenza kahle, ngaleyo ndlela kuncishiswe ukukhishwa kwezinto eziyingozi njenge-carbon dioxide, i-carbon monoxide kanye ne-nitrogen oxides emthanjeni wangemuva.
Ukubaluleka kokushintshashintsha kwemoto
Ukulungiswa kokusebenza kahle: Ukulawulwa okunembile kwe-throttle kuthuthukisa izici zokukhipha amandla enjini, njengamandla ne-torque, okuthuthukisa ulwazi lokushayela.
Ukonga uphethiloli: Ngokulungisa ukugeleza komoya ngendlela enembile, ivalvu ye-throttle isiza ukuthuthukisa ukusebenza kahle kokushisa uphethiloli nokunciphisa ukusetshenziswa kukaphethiloli.
Umnikelo wezemvelo: Ama-valve e-throttle adlala indima ebalulekile ekunciphiseni ukukhishwa kwegesi okuyingozi futhi ahambisana nemithethonqubo yezemvelo eqinile.
Ukugcinwa kanye nezinyathelo zokuphepha
Njengomnikazi wemoto, kubalulekile ukuhlanza nokugcina i-throttle njalo ukuqinisekisa ukuthi isebenza kahle nokugcina injini isebenza kahle kakhulu. Isibonelo, ukufakwa kwekhabhoni kungathinta isivinini sokuphendula kwe-throttle kanye nokunemba kokuvula kwayo, ngakho-ke idinga ukuhlolwa nokuhlanzwa njalo.
Ngamafuphi, i-throttle yezimoto iyisici esibalulekile sohlelo lokuphathwa kwenjini, esinomthelela obalulekile ekusebenzeni kwemoto, ukonga uphethiloli kanye nokulawula ukukhishwa komoya ongcolile endaweni ezungezile.
Umsebenzi oyinhloko we-automotive throttle valve (eyaziwa nangokuthi i-throttle valve) ukulawula ukukhishwa kwamandla kanye nokusebenza kahle kukaphethiloli ngokulawula ivolumu yokungenisa injini. Imisebenzi yayo ethile ingafingqwa kanje:
Ukulawulwa kwamandla kanye nokulawulwa kwesivinini
Umshayeli ulawula ngqo ukugeleza komoya enjinini ngokunyathela i-accelerator pedal ukuze ashintshe ukuvulwa kwe-throttle. Lapho ukugeleza komoya kukhuphuka, ivolumu yokufaka uphethiloli iyanda ngokufanayo, futhi ukushisa kugcwele kakhulu, ngaleyo ndlela kwandisa amandla enjini (njengokusheshisa noma izimo zokukhuphuka); Ngokuphambene nalokho, isivinini kanye nokusetshenziswa kukaphethiloli kuyancishiswa (njengezimo zejubane elifanayo noma zokunciphisa ijubane). Lokhu kulungiswa kuvumela imoto ukuthi iphendule ngokuguquguqukayo ezidingweni ezahlukene zokushayela.
Ukuthuthukiswa kokukhishwa komoya kanye nokusebenza kahle kokushisa
I-throttle valve inciphisa inani le-carbon monoxide (CO) kanye nama-hydrocarbon (HC) kugesi yokukhipha umoya ngokulawula ngokunembile isilinganiso somoya-fuel. Isibonelo, ngaphansi kwezimo zomthwalo ophansi, ukunciphisa okufanele ukungena komoya kungenza ukushisa kube kukhulu futhi kunciphise ukukhishwa kokungcola.
Ukulawulwa Kokuvikelwa Kwenjini Nokuphepha
Uma kutholakala izimo ezingavamile njengokungqongqoza nomlilo, i-throttle valve ingakhawulela ngokushesha ivolumu yokungena futhi inciphise umthwalo wenjini ukuze kugwenywe umonakalo wemishini. Ngesikhathi esifanayo, umsebenzi wayo womkhawulo wejubane uvimbela ukuguguleka kwezingxenye ngenxa yesivinini esikhulu.
ukubambisana kwesistimu yokusiza
Ezinhlelweni ze-turbocharged noma ze-hybrid, i-throttle ixhunywe kuyunithi yokulawula kagesi (i-ECU) ukuze kuthuthukiswe ukucindezela kanye nokusebenza kahle kokubuyisa amandla. Isibonelo, amanye amamodeli anciphisa ukumelana kokungenisa futhi athuthukise ukubuyisa amandla ngokuvala i-throttle ngesikhathi sokubhuleka.
Isibonelo somehluko wohlelo lokusebenza
Izimoto zikadizili ezihlonyiswe ngama-valve e-throttle: zisetshenziselwa kakhulu ukulawula ukukhishwa komoya kunokulawula amandla (ngoba izinjini zikadizili zisebenzisa isimiso sokusebenza sokucindezela ukushisa)
Izinhlelo ze-hybrid: Ama-valve e-throttle avame ukusebenza ndawonye nenjini ukuze kusatshalaliswe amandla ngendlela enembile.
