Kodi throttle ya galimoto ndi chiyani?
Vavu yopukutira ndi valavu yomwe imalamulira mpweya wolowa mu injini ndikusintha mphamvu yotulutsa ndi kugwiritsa ntchito mafuta a injini mwa kusintha kayendedwe ka mpweya.
Ma valve opopera magalimoto, omwe amadziwikanso kuti ma valve opopera kapena ma valve opopera gasi, ndi zinthu zofunika kwambiri mu makina oyang'anira injini zamagalimoto. Ntchito yake yayikulu ndikulamulira mphamvu yotulutsa ndi kugwiritsa ntchito mafuta a injini mwa kulamulira kayendedwe ka mpweya kulowa mu injini, zomwe zimakhudza kuchuluka kwa mafuta omwe amalowetsedwa mu injini.
Mfundo yogwirira ntchito ya valavu yopumira yamagalimoto
Kuwongolera kayendedwe ka mpweya: Dalaivala akakanikiza pedal ya gasi, masensa amasintha ntchitoyo kukhala chizindikiro chamagetsi chomwe chimatumizidwa ku electronic control Unit (ECU). ECU imasintha kutseguka kwa valavu ya throttle nthawi yeniyeni malinga ndi malo a throttle, momwe injini ilili ndi zinthu zina, motero imayang'anira kuchuluka kwa mpweya wolowa mu injini.
Kulamulira mphamvu yotulutsa mphamvu: Kusintha kwa kutsegula kwa valavu ya throttle kumakhudza mwachindunji kuchuluka kwa injini, zomwe zimakhudza kuchuluka kwa mafuta omwe amalowa komanso momwe amayatsira bwino. Kuwonjezera kutsegula kumawongolera magwiridwe antchito a injini, pomwe kuchepetsa kutsegula kumathandiza kuchepetsa kugwiritsa ntchito mafuta.
Kuwongolera Zachilengedwe ndi Utsi: Mwa kuwongolera bwino kuchuluka kwa mpweya ndi mafuta, ma valve opopera amathandizira kukwaniritsa njira yoyaka bwino, potero amachepetsa kutulutsa kwa zinthu zovulaza monga carbon dioxide, carbon monoxide ndi nitrogen oxides m'chitoliro cham'mbuyo.
Kufunika kwa throttle ya galimoto
Kuwongolera magwiridwe antchito: Kuwongolera bwino kwa throttle kumawongolera mawonekedwe a mphamvu ya injini, monga mphamvu ndi torque, zomwe zimapangitsa kuti kuyendetsa bwino kukhale koyenera.
Kusunga mafuta: Kudzera mu kusintha kwa kayendedwe ka mpweya molondola, valavu yopukutira mafuta imathandiza kukonza kuyaka bwino kwa mafuta ndikuchepetsa kugwiritsa ntchito mafuta.
Zothandizira zachilengedwe: Ma valve oteteza mpweya amathandiza kwambiri kuchepetsa mpweya woipa komanso kutsatira malamulo okhwima okhudza chilengedwe.
Kusamalira ndi njira zodzitetezera
Monga mwini galimoto, ndikofunikira kuyeretsa ndi kusamalira throttle nthawi zonse kuti muwonetsetse kuti ikugwira ntchito bwino komanso kuti injini igwire bwino ntchito. Mwachitsanzo, kuyika mpweya m'galimoto kungakhudze liwiro la throttle komanso kutseguka kwake molondola, kotero iyenera kuyang'aniridwa ndikutsukidwa nthawi zonse.
Mwachidule, mphamvu yoyendetsa galimoto ndi gawo lofunika kwambiri pa kayendetsedwe ka injini, zomwe zimakhudza kwambiri magwiridwe antchito a galimoto, kuchepetsa mafuta komanso kuwongolera utsi woipa womwe umawononga chilengedwe.
Ntchito yaikulu ya valavu yothira mafuta yagalimoto (yomwe imadziwikanso kuti valavu yothira mafuta) ndikuwongolera mphamvu yotulutsa mafuta komanso kugwiritsa ntchito bwino mafuta mwa kuwongolera kuchuluka kwa injini yomwe imalowa. Ntchito zake zenizeni zitha kufotokozedwa motere:
Kulamulira mphamvu ndi kuwongolera liwiro
Dalaivala amalamulira mwachindunji kayendedwe ka mpweya kulowa mu injini poponda pedal yotsatsira kuti asinthe malo otseguka a throttle. Pamene kayendedwe ka mpweya kakukwera, kuchuluka kwa mafuta omwe amalowa m'galimoto kumawonjezeka mofanana, ndipo kuyaka kumakhala kodzaza kwambiri, motero kumawonjezera mphamvu ya injini (monga kuthamanga kapena kukwera); M'malo mwake, liwiro ndi kugwiritsa ntchito mafuta zimachepa (monga liwiro lofanana kapena kuchepetsa liwiro). Kusintha kumeneku kumalola galimotoyo kuyankha mosavuta ku zosowa zosiyanasiyana zoyendetsa.
Kukonza bwino mpweya woipa ndi kukonza bwino kutentha kwa moto
Valavu yopukutira mpweya imachepetsa kuchuluka kwa carbon monoxide (CO) ndi ma hydrocarbons (HC) mu mpweya wotulutsa utsi mwa kuwongolera bwino kuchuluka kwa mpweya ndi mafuta. Mwachitsanzo, ngati katundu ndi wotsika, kuchepetsa koyenera kwa mpweya wolowa kungapangitse kuyaka kukhala kokwanira komanso kuchepetsa kutulutsa mpweya woipa.
Chitetezo cha Injini ndi Kulamulira Chitetezo
Zinthu zosazolowereka monga kugogoda ndi kuyaka zikapezeka, valavu yotsekera imatha kuchepetsa mwachangu kuchuluka kwa injini ndikuchepetsa katundu wa injini kuti ipewe kuwonongeka kwa makina. Nthawi yomweyo, ntchito yake yoletsa liwiro imaletsa kuwonongeka kwa zigawo chifukwa cha liwiro lalikulu.
mgwirizano wothandizira wa dongosolo
Mu makina okhala ndi turbocharged kapena hybrid, throttle imalumikizidwa ndi electronic control unit (ECU) kuti iwonjezere mphamvu ndi kubwezeretsanso mphamvu. Mwachitsanzo, mitundu ina imachepetsa kukana kudya ndikuwongolera kubwezeretsanso mphamvu mwa kutseka throttle panthawi yotseka.
Kusiyana kwa zitsanzo za ntchito
Magalimoto a dizilo okhala ndi ma valve opopera: amagwiritsidwa ntchito makamaka powongolera mpweya woipa m'malo mowongolera mphamvu (chifukwa injini za dizilo zimagwiritsa ntchito mfundo yogwirira ntchito yopondereza kuyaka)
Machitidwe a Hybrid: Ma valve a throttle nthawi zambiri amagwira ntchito limodzi ndi injini kuti apereke mphamvu molondola.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
