Yintoni i-throttle yemoto
Ivalvu yokuphuthuma yivalvu elawula umoya wokungenisa injini kwaye ilungisa amandla okukhupha kunye nokusetyenziswa kwepetroli yenjini ngokulungelelanisa ukuhamba komoya.
Iivalvu ze-throttle zezithuthi, ezaziwa ngokuba ziivalvu ze-throttle okanye iivalvu ze-gas pedal, zizinto ezibalulekileyo kwiinkqubo zolawulo lweenjini zezithuthi. Umsebenzi wayo ophambili kukulawula amandla aphumayo kunye nokusetyenziswa kwepetroli yenjini ngokulawula ukuhamba komoya kwinjini, nto leyo echaphazela ubungakanani bokufakwa kwepetroli.
Umgaqo wokusebenza wevalvu ye-throttle yemoto
Ulawulo lokuhamba komoya: Xa umqhubi ecinezela ipedali yegesi, ii-sensors ziguqula isenzo sibe sisignali yombane edluliselwa kwiYunithi yoLawulo lwe-elektroniki (ECU). I-ECU ilungisa ukuvulwa kwevalvu ye-throttle ngexesha langempela ngokwendawo ye-throttle, imeko yenjini kunye nezinye izinto, ngaloo ndlela ilawula ubungakanani bomoya ongena enjinini.
Ulawulo lokukhupha amandla: Utshintsho lokuvula ivalvu ye-throttle luchaphazela ngokuthe ngqo umthamo wokungenisa injini, nto leyo echaphazela ubungakanani bokufakwa kwepetroli kunye nokusebenza kakuhle kokutshisa. Ukwandisa ukuvulwa kuphucula ukusebenza kwenjini, ngelixa ukunciphisa ukuvulwa kunceda ukunciphisa ukusetyenziswa kwepetroli.
Ulawulo lweNdalo kunye noKhuhlane: Ngokulawula ngokuchanekileyo umlinganiselo womoya kunye namafutha, iivalvu ze-throttle zinceda ekufezekiseni inkqubo yokutsha esebenza ngcono, ngaloo ndlela kunciphisa ukukhutshwa kwezinto eziyingozi ezifana ne-carbon dioxide, i-carbon monoxide kunye ne-nitrogen oxides kumbhobho wasemva.
Ukubaluleka kwe-throttle yemoto
Ukulungiswa kokusebenza: Ulawulo oluchanekileyo lwe-throttle luphucula iimpawu zokukhupha amandla enjini, ezinje ngamandla kunye ne-torque, nto leyo ephucula amava okuqhuba.
Ukonga amafutha: Ngokulungisa ngokuchanekileyo ukuhamba komoya, ivalvu ye-throttle inceda ukuphucula ukusebenza kakuhle kokutsha kwamafutha kunye nokunciphisa ukusetyenziswa kwamafutha.
Igalelo kwindalo esingqongileyo: Iivalvu zombhobho zidlala indima ebalulekileyo ekunciphiseni ukukhutshwa kwegesi eyingozi kwaye zithobela imithetho engqongqo yokusingqongileyo.
Ukugcinwa kunye neendlela zokhuseleko
Njengomnini wemoto, kubalulekile ukucoca nokugcina i-throttle rhoqo ukuqinisekisa ukuba isebenza kakuhle kwaye igcine injini isebenza kakuhle. Umzekelo, ukufakwa kwekhabhoni kunokuchaphazela isantya sempendulo ye-throttle kunye nokuchaneka kokuvula kwayo, ngoko ke kufuneka ihlolwe kwaye icocwe rhoqo.
Ngamafutshane, i-throttle yeemoto yinxalenye ebalulekileyo yenkqubo yolawulo lweenjini, enefuthe elibalulekileyo ekusebenzeni kwesithuthi, ukonga amafutha kunye nolawulo lokukhutshwa komoya ongcolileyo kwindalo esingqongileyo.
Umsebenzi ophambili wevalvu ye-throttle yemoto (ekwaziwa ngokuba yivalvu ye-throttle) kukulawula umbane ophumayo kunye nokusebenza kakuhle kwepetroli ngokulawula umthamo wokungenisa injini. Imisebenzi yayo ethile ingashwankathelwa ngolu hlobo lulandelayo:
Ulawulo lwamandla kunye nolawulo lwesantya
Umqhubi ulawula ngokuthe ngqo ukuhamba komoya kwinjini ngokunyathela i-accelerator pedal ukutshintsha indawo evulekayo ye-throttle. Xa ukuhamba komoya kusanda, umthamo we-fuel injection uyanda ngokufanayo, kwaye ukutsha kugcwele ngakumbi, nto leyo enyusa amandla enjini (njengokukhawulezisa okanye ukunyuka); Ngokwahlukileyo koko, isantya kunye nokusetyenziswa kwepetroli kuyancitshiswa (njengesantya esifanayo okanye iimeko zokucothisa). Olu hlengahlengiso luvumela imoto ukuba iphendule ngokulula kwiimfuno ezahlukeneyo zokuqhuba.
Ukuphucula ukusebenza kakuhle kokukhupha umoya kunye nokuphucula ukusebenza kakuhle kokutshisa
Ivalvu ye-throttle inciphisa ubungakanani be-carbon monoxide (CO) kunye nee-hydrocarbons (HC) kwigesi yokukhupha umoya ngokulawula ngokuchanekileyo umlinganiselo womoya-fuel. Umzekelo, phantsi kweemeko zomthwalo ophantsi, ukunciphisa ngokufanelekileyo ukungena komoya kunokwenza ukutsha kube nzima ngakumbi kwaye kunciphise ukukhutshwa kongcoliseko.
Ulawulo loKhuseleko lweNjini kunye noKhuseleko
Xa kufunyenwe iimeko ezingaqhelekanga ezifana nokungqongqoza nomlilo, ivalvu ye-throttle ingakhawulezisa ukunciphisa umthamo wokungenisa kwaye inciphise umthwalo wenjini ukuze kuthintelwe umonakalo woomatshini. Kwangaxeshanye, umsebenzi wayo womda wesantya uthintela ukuguguleka kwezixhobo ngenxa yesantya esiphezulu.
ulungelelwaniso lwenkqubo encedisayo
Kwiinkqubo ezine-turbocharged okanye ezixutyiweyo, i-throttle iqhagamshelwe kwiyunithi yolawulo lwe-elektroniki (ECU) ukuze kuphuculwe ukunyusa uxinzelelo kunye nokusebenza kakuhle kokubuyisela amandla. Umzekelo, ezinye iimodeli zinciphisa ukumelana nokungena kwaye ziphucule ukubuyiselwa kwamandla ngokuvala i-throttle ngexesha lokubhuleka.
Umzekelo womahluko wesicelo
Izithuthi zedizili ezixhotyiswe ngeevalvu ze-throttle: zisetyenziselwa kakhulu ukulawula ukukhutshwa komoya endaweni yokulawula umbane (kuba iinjini zedizili zisebenzisa umgaqo wokusebenza kokucinezelwa komlilo)
Iinkqubo zeHybrid: Iivalvu zombhobho zihlala zisebenza ngaxeshanye nemoto ukuze kusasazwe amandla ngokuchanekileyo.
