Chidziwitso cha malonda:
Dongosolo la jekeseni wa dizilo limayatsa mafutawo ndikugawa pakati pa zigawo zomwe zimasakanikirana ndi mpweya muchipinda choyaka.
Amapangidwa makamaka ndi jekeseni wamafuta ndi thupi la jekeseni.Majekeseni amafuta omwe amaikidwa pamutu wa silinda amagawidwa m'mitundu iwiri: mtundu wotseguka ndi mtundu wotsekedwa.Injector yotseguka imakhala ndi mawonekedwe osavuta koma ma atomization ndi osagwiritsidwa ntchito kawirikawiri.Majekeseni otsekedwa amagwiritsidwa ntchito kwambiri mu injini zosiyanasiyana za dizilo.Injini ya dizilo imakoka mpweya wabwino panthawi yomwe akudwala.Pamene kuponderezedwa kukuyandikira kumapeto, mafuta a dizilo amawonjezeka kufika pa 100MPa ndi pampu ya jekeseni ya mafuta, jekeseni mu silinda kupyolera mu jekeseni wa mafuta, ndikusakanikirana ndi mpweya wotentha kwambiri mu nthawi yochepa kwambiri kuti apange choyaka osakaniza.Chifukwa cha psinjika mkulu chiŵerengero cha injini dizilo (kawirikawiri 16-22), kuthamanga mpweya mu yamphamvu akhoza kufika 3.5-4.5MPa pa mapeto a psinjika, ndi kutentha ndi mkulu monga 750-1000K (pamene mpweya osakaniza kuthamanga wa injini mafuta pa nthawi imeneyi adzakhala 0.6-1.2MPa , kutentha kufika 600-700K), amene kwambiri kuposa kudzikonda poyatsira kutentha dizilo.Choncho, mafuta a dizilo akalowetsedwa mu cylinder, nthawi yomweyo amawotcha ndikuyaka yokha pambuyo posakanikirana ndi mpweya mu nthawi yochepa kwambiri.Kuthamanga kwa mpweya mu silinda kumakwera mofulumira kufika ku 6-9MPa, ndipo kutentha kumakweranso kufika 2000-2500K.Poyendetsedwa ndi mpweya wothamanga kwambiri, pisitoni imatsika pansi ndikuyendetsa crankshaft kuti izungulira kuti igwire ntchito, ndipo mpweya wotulutsa mpweya umatulutsidwanso mumlengalenga kudzera mu chitoliro chotulutsa mpweya.
Injini ya dizilo wamba imayendetsedwa ndi camshaft ya injini, ndipo mafuta a dizilo amaperekedwa kuchipinda chamafuta pa silinda iliyonse pogwiritsa ntchito pampu yamafuta yothamanga kwambiri.Njira yoperekera mafuta iyi iyenera kusintha ndikusintha kwa liwiro la injini, ndipo kuchuluka kwamafuta oyenera pama liwiro osiyanasiyana sikungakwaniritsidwe.Dongosolo lodziwika bwino la jakisoni wamafuta anjanji limapangidwa ndi pampu yamafuta othamanga kwambiri, chitoliro chamafuta wamba, jekeseni wamafuta, gawo lowongolera zamagetsi (ECU) ndi masensa ena amapaipi.Injector iliyonse yamafuta mu dongosolo imalumikizidwa ndi mafuta wamba kudzera pa chitoliro chake champhamvu chamafuta.Mipopeyo imalumikizidwa, ndipo chitoliro chamafuta wamba chimagwira ntchito ngati hydraulic pressure accumulator ya jekeseni.Pogwira ntchito, pampu yamafuta othamanga kwambiri imapereka mafuta ku chitoliro chamafuta amtundu wapagulu pakuthamanga kwambiri, ndipo pampu yamafuta othamanga kwambiri, sensa yamagetsi ndi ECU imapanga ntchito yotseka kuti iwonetsetse kuthamanga kwamafuta pagulu lamafuta. chitoliro, kusintha kwathunthu kuthamanga kwa mafuta ndi kusintha kwa liwiro la injini.Zodabwitsa.Zigawo zake zazikulu ndi izi:
1. Nthawi ya jekeseni ya mafuta imasiyanitsidwa kwathunthu ndi metering ya mafuta, ndipo kuthamanga kwa jekeseni wa mafuta ndi ndondomeko ya jekeseni ya mafuta imayendetsedwa ndi ECU mu nthawi.
2. Kuthamanga kwa jekeseni wa mafuta pa silinda iliyonse, malo oyambira ndi nthawi ya jekeseni wa mafuta akhoza kusinthidwa malinga ndi momwe injini ikugwirira ntchito, kuti atsatire njira yabwino yoyendetsera jekeseni wa mafuta.
3. Kuthamanga kwambiri kwa jekeseni wamafuta ndi jekeseni ya dizilo isanayambe kutheka.
