Kodi Automotive turbocharger control ndi chiyani
Makina owongolera agalimoto a turbocharger amadziwika makamaka ndi makina owongolera amagetsi otulutsa mpweya wa turbocharger pressure control system. Dongosololi limapangidwa ndi valavu yothandizira solenoid, pneumatic actuator, bypass valve ndi supercharger. Kuwongolera kwa kupanikizika kwa dongosolo lachilimbikitso kumazindikiridwa kupyolera mu kutsegula ndi kutseka kwa valve yodutsa: pamene valavu yodutsa imatsekedwa, pafupifupi mpweya wonse wotulutsa mpweya umayenda kupyolera mu chilimbikitso, ndipo mphamvu yowonjezera ikuwonjezeka; Pamene valavu yodutsa imatsegulidwa, gawo lina la mpweya wotulutsa mpweya limatulutsidwa mwachindunji kudzera munjira yodutsa, ndipo mphamvu ya booster imachepetsedwa.
Kutsegula ndi kutseka kwa valve bypass kumatheka ndi ECU (Electronic control Unit) kupyolera mu kuwongolera kwa valve solenoid valve ndi pneumatic actuator. ECU imayang'anira kuthamanga kwamphamvu molingana ndi kukakamizidwa kwa ma intake, ndipo valavu yodutsa imatsegulidwa pa liwiro lalikulu komanso katundu wamkulu kuti apewe kuchulukitsitsa kwamakina ndi kutentha kwa injini pa liwiro lalikulu. Kuonjezera apo, zitsanzo zina zimagwiritsanso ntchito njira yotsekera-loop, kupyolera mu sensa ya malo kuti idyetse zotsatira zenizeni za kuphedwa kwa ECU, kusintha molingana ndi kupatuka, kuti muwongolere molondola mphamvu ya injini .
Mfundo yogwirira ntchito ya turbocharger ndikuyendetsa turbine kudzera mu mpweya wotulutsa mpweya wotulutsidwa ndi injini, ndiyeno kukanikiza mpweya wolowa kuti uwongolere kachulukidwe ka mpweya, motero kuwongolera kuyaka bwino komanso mphamvu zotulutsa. Turbocharger imagwiritsa ntchito mphamvu ya inertia ya mpweya wotulutsa mpweya wotulutsidwa ndi injini kukankhira turbine m'chipinda cha turbine, imayendetsa coaxial impeller kuti ipanikizire mpweya mu silinda, kumawonjezera kuthamanga ndi kachulukidwe ka mpweya, motero kumawonjezera mphamvu ya injini.
Ntchito zazikulu zamagalimoto a turbocharger zikuphatikiza izi:
Wonjezerani mphamvu ya injini ndi torque : Ma turbocharger amawonjezera kuchuluka kwa mpweya womwe umalowa mu silinda, zomwe zimapangitsa injini kubaya mafuta ochulukirapo pamalo omwewo, potero amawonjezera mphamvu ya injini ndi torque. Ambiri, turbocharger akhoza kuonjezera mphamvu pazipita injini ndi 20% mpaka 40%, ndi makokedwe pazipita 30% mpaka 50%.
Chepetsani kugwiritsa ntchito mafuta komanso kutulutsa mpweya : Ma Turbocharger amachepetsa kugwiritsa ntchito mafuta komanso kutulutsa mpweya mwa kukhathamiritsa kuyaka kwa injini ndikuwongolera kutentha. Makamaka, turbocharger imatha kuchepetsa kugwiritsa ntchito mafuta a injini ndi 5% mpaka 10%, komanso kutulutsa mpweya woipa monga CO, HC ndi NOx kumachepetsedwanso.
Kukwera kwamafuta amafuta : Injini zokhala ndi ma turbocharger zimayaka bwino, kupulumutsa 3% mpaka 5% yamafuta. Kuphatikiza apo, ma turbocharger amakulitsa mawonekedwe ofananira ndi injini komanso mawonekedwe oyankha kwakanthawi kuti apititse patsogolo chuma chamafuta.
Limbikitsani kusinthika kwa injini ndi kudalirika : Turbocharger imatha kupanga injini pamtunda wosiyanasiyana, kutentha ndi katundu kuti ikhale yogwira ntchito bwino komanso yokhazikika, kupewa injini yocheperako, kugogoda, kutenthedwa ndi zovuta zina. Nthawi yomweyo, ma turbocharger amathanso kukulitsa moyo wa injini ndikuchepetsa kulephera.
Ntchito yamalipiro a Plateau : m'dera lamapiri, chifukwa cha mpweya woonda, magwiridwe antchito a injini wamba adzakhudzidwa ndipo mphamvu idzachepa. The turbocharger imatha kukonza bwino kutayika kwa mphamvu chifukwa cha mpweya wochepa kwambiri powonjezera kuchuluka kwa kudya.
