Onani Kukula kwa Dizilo Generator Intake System

1, jenereta ya Cummins imayika makina otengera mpweya

Turbocharging ndi kompresa ya mpweya yomwe imagwiritsa ntchito mitambo ya mpweya wotulutsa mpweya kuchokera mu injini yoyaka mkati kuti iyendetse.Chipangizo cha supercharging chimatha kusintha kuchuluka kwa mpweya mu silinda mwa kukanikiza mpweya wofunikira pakuyatsa kwamafuta pansi pa kuchuluka komweko kogwirira ntchito komanso liwiro la jenereta ya dizilo , kenako kusintha mphamvu kachulukidwe wa jenereta dizilo.The zikuchokera dongosolo supercharger osati zikuphatikizapo supercharger thupi, intercooler, supercharger yozizira payipi hardware thupi, komanso monga supercharger kuthamanga sensa, mpweya otaya mita, liwiro sensa, detonation sensa, jekeseni mafuta, poyatsira koyilo ndi masensa ena amagetsi chizindikiro. ndemanga.Thupi lalikulu la Turbocharger limaphatikizapo valavu yotulutsa mpweya ndi valavu yopumira yolowera, chizindikiro cha sensor yamagetsi, monga dongosolo la EMS kudzera pa liwiro la oyendetsa pakufunika kwa mphamvu ya jenereta ya dizilo, kuti atulutse chiŵerengero cha ntchito yokakamiza, kuwongolera mutu wapamwamba kwambiri. valavu kutsegula, kuti utsi wochulukira mu turbine turbine mbali, kuonjezera kuthamanga, pangani kupsyinjika kolowera kukwaniritsa zolinga, Kuonjezera mphamvu ya jenereta dizilo.Pamene EMS imalandira galimoto kuchokera ku sensa iliyonse yamagetsi sichiyenera kulimbikitsa mphamvu, panthawiyi EMS linanena bungwe pressurized ntchito chiŵerengero ndi 0, utsi kuchokera bypass kukhetsa mapaipi, supercharger salinso kukakamizidwa pa kudya;EMS imayang'aniranso kutsegulidwa kwa valavu yochepetsera mphamvu yowonjezera pa supercharger kuti muchepetse msanga kupanikizika kwa mlingo wosakanizidwa ndi mphamvu ya jenereta ya dizilo ku mphamvu yomwe mukufuna.Makhalidwe a supercharger amatsimikizira kuchuluka kwamphamvu kwa supercharger.Makhalidwe a chibadwidwe cha supercharger amaphatikizapo kuthamanga kwakukulu komwe kumaloledwa ndi supercharger ndi mzere wothamanga wa supercharger.Pamene mtundu wina wa supercharger wasankhidwa kwa jenereta ya dizilo, makhalidwe amtundu wa supercharger amatsimikiziridwa.Malinga ndi liwiro lalikulu lovomerezeka la turbocharger ndi mzere wothamanga wa turbocharger, chiŵerengero chapamwamba cha turbocharging pa liwiro lililonse lamagetsi chimawerengedwa kuti chiwongolero cha jenereta ya dizilo chikuyesedwa.Pambuyo pa mawerengedwe a jenereta ya dizilo, njira yoyendetsera turbocharger yatsimikiziridwa.

Pamene liwiro ndi katundu wa jenereta wa dizilo akusintha, kuchuluka kwa mphamvu, kutulutsa mphamvu, kuthamanga ndi kuthamanga kwa mpweya, nthawi ya kulowetsedwa ndi kutulutsa mpweya, kuyaka kwa silinda ndi zosiyana, ndipo zofunikira za gawo la valve ndi kukweza kwa valve ndizosiyana. komanso zosiyana.Mwachitsanzo: pamene liwiro liri lalitali, kuthamanga kwa inlet ndikokwera kwambiri ndipo mphamvu ya inertia ndi yaikulu, kotero tikuyembekeza kuti valve yolowera idzatsegulidwa kale ndikutsekedwa pambuyo pake, kuti agwiritse ntchito mokwanira inertia ya kulowa. yendani ndi kulipiritsa mpweya watsopano mu silinda momwe mungathere;M'malo mwake, pamene liwiro la jenereta ya dizilo liri lochepa, kutsika kwa mpweya kumakhala kochepa, ndipo mphamvu ya inertia imakhala yochepa.Ngati valavu yotsekera mochedwa Engle ndi yayikulu kwambiri, mpweya watsopano womwe walowa mu silindayo udzafinyidwa mu silinda ndi pisitoni yopita m'mwamba pokanikizira.Mofananamo, ngati valavu yolowetsa imatsegulidwa mofulumira kwambiri, chifukwa pisitoni ikukwera utsi, n'zosavuta kufinya mpweya wotulutsa mpweya mu chitoliro cholowera, kuti mpweya wotsalira wotsalira uwonjezeke, koma mpweya watsopano umachepetsedwa, kotero. kuti jenereta ya dizilo siikhazikika.Zotsatira zake, palibe gawo lokhazikika la valve lomwe limapereka ntchito yabwino kwa majenereta a dizilo pa liwiro lapamwamba komanso lotsika.Dongosolo la variable valve timing (VVT) likhoza kupititsa patsogolo chuma chamafuta, mphamvu zamagetsi ndi kukhazikika kwa majenereta a dizilo pansi pa liwiro losiyanasiyana ndi katundu posintha gawo logawa majenereta a dizilo, ndikuchepetsa kuipitsidwa kwa mpweya.

3, Cummins jenereta anapereka luso valavu zamagetsi

Majenereta a dizilo pa liwiro losiyanasiyana.Zofunikira pakuyenda ma valve zimasiyana kwambiri.Pa liwiro lotsika, chifukwa voliyumu yolowera ndi yaying'ono, ngati kuyenda kwa valavu kuli kwakukulu, sikungathe kutulutsa mphamvu yokwanira yolowera, jekeseni sangathe kusakanikirana bwino ndi mpweya wopumira pambuyo pa jekeseni, zomwe zimapangitsa kuti pakhale kuyaka kochepa, torque yotsika kwambiri idzachepetsedwa kwambiri, ndipo mpweya udzawonjezekanso.Pankhaniyi, valavu yaying'ono iyenera kugwiritsidwa ntchito.Chifukwa cha maulendo ang'onoang'ono a valve, kupanikizika kolakwika kwa kudya kumawonjezeka, ndipo zotsatira zambiri za vortices zimatha kusakaniza kusakaniza kuti zigwirizane ndi ntchito yachibadwa ya jenereta ya dizilo pa liwiro lochepa.Pa liwiro lalikulu, zinthu ndi zosiyana.Panthawi imeneyi, kuchuluka kwa kudya kumakhala kwakukulu kwambiri.Ngati kuyenda kwa valve kuli kochepa kwambiri, kukana kulowetsedwa kudzakhala kwakukulu kwambiri kuti musapume mpweya wokwanira, motero kumakhudza kugwira ntchito kwa mphamvu.Choncho, pa liwiro lalikulu, m'pofunika kukhala ndi maulendo akuluakulu a valve, kuti mupeze kufunikira kwa valve yabwino.Kuti muchepetse kugwiritsa ntchito mafuta, makina osinthika a BMW amawongolera kuchuluka kwa mpweya mu jenereta ya dizilo osati kudzera pa throttle koma kudzera pakukweza kosinthika kwa valavu yolowera.Pogwiritsa ntchito shaft yosinthika yamagetsi, zochita za camshaft pa rod valve pressure rod zimasinthidwa ndi lever yapakatikati, potero imapanga chokwera chokwera.The throttle imangogwiritsidwa ntchito poyambira komanso ntchito yadzidzidzi.Muzochitika zina zonse zogwirira ntchito throttle imatsegulidwa kwathunthu ndikugwedeza pang'ono.Tekinoloje yamagetsi yamagetsi imakwaniritsa bwino mphamvu yamagetsi yamagetsi yamagetsi yamagetsi yamagetsi pansi pamikhalidwe yosiyanasiyana yothamanga kudzera pakusintha kosasintha kwa valavu.

Kupita patsogolo kosalekeza kwa anthu masiku ano kwadzetsanso mavuto ambiri pa chilengedwe chimene tikukhala.Zikatero, mchikakamizo cha tsogolo chitukuko cha sayansi ndi luso la generating ya otsika mpweya, kupulumutsa mphamvu, chilengedwe chitetezo chitukuko pang'onopang'ono wakhala achizolowezi, chitukuko cha jenereta dizilo mpweya kudya dongosolo kafukufuku, osati thandizo. Timamvetsetsanso chitukuko cha kachitidwe ka jenereta ya dizilo ya mpweya, komanso kuti tiphunzire m'tsogolomu kufufuza kwa mpweya wa jenereta kumagwira ntchito, Kuipa kwa kugwiritsa ntchito mafuta ambiri komanso kuipitsidwa kwakukulu kwa ma seti a jenereta kumatha kuthetsedwa pang'onopang'ono.
