Ubwino ndi kuipa kwa injini ya dizilo ya common rail yomwe imayendetsedwa ndi mphamvu yamagetsi ndi ziti?

Ndi chitukuko chopitilira cha njira zopangira mafakitale ku China, chiŵerengero cha kuipitsidwa kwa mpweya chayamba kukwera, ndipo ndikofunikira kwambiri kukonza kuipitsidwa kwa chilengedwe. Poyankha mavutowa, boma la China lakhazikitsa nthawi yomweyo mfundo zambiri zoyenera zochotsera mpweya wa injini ya dizilo. Pakati pawo, injini za dizilo za sitima zapamtunda zomwe zimakhala ndi mpweya wa National III ndi Euro III pamsika wa jenereta ya dizilo zikutchuka kwambiri pamsika.

Injini ya dizilo yamagetsi yamagetsi yamagetsi imatanthawuza njira yoperekera mafuta yomwe imalekanitsa kwathunthu kupanga kwa kuthamanga kwa jakisoni ndi njira yojambulira mu dongosolo lotsekedwa lopangidwa ndi pampu yamafuta yamagetsi yamagetsi, sensa yamagetsi ndi unit yowongolera zamagetsi (ECU). Ma injini a dizilo olamulidwa ndi magetsi sadaliranso kuzama kwa throttle ya dalaivala kuti alamulire kuchuluka kwa jakisoni yamafuta a pampu yamakina, koma amadalira ECU yamagetsi kuti igwiritse ntchito zambiri za makina onse. ECU idzayang'anira momwe injini ilili nthawi yeniyeni ndikusintha jakisoni yamafuta malinga ndi malo a accelerator pedal. Nthawi ndi kuchuluka kwa jakisoni yamafuta. Masiku ano, injini za dizilo zimagwiritsidwa ntchito kwambiri mu dongosolo la jakisoni yamafuta la m'badwo wachitatu la "nthawi yowongolera kuthamanga kwamagetsi", kutanthauza, njanji yamagetsi yamagetsi yamagetsi yamagetsi.

Ubwino wa injini za dizilo za common rail zothamanga kwambiri ndi kugwiritsa ntchito mafuta ochepa, kudalirika kwambiri, moyo wautali, komanso mphamvu yayikulu. Mainjini a dizilo okhala ndi common rail amatulutsa mpweya woipa kwambiri kuposa mainjini opanda common rail (makamaka CO yochepa), kotero ndi abwino kwa chilengedwe poyerekeza ndi mainjini a petulo.

Zoyipa za injini za dizilo zamtundu wa common rail zomwe zimakhala ndi mphamvu yayikulu zimaphatikizapo ndalama zambiri zopangira ndi kukonza (mitengo), phokoso lalikulu, komanso kuvutika kuyatsa. Ngati injini ikugwira ntchito kwa nthawi yayitali, kutentha kwa injini ndi kupanikizika kumakhala kwakukulu, ndipo soot ndi coke zambiri zimapangidwa m'masilinda, ndipo mafuta a injini nawonso amatha kusungunuka kuti apange chingamu. Chifukwa chake, mafuta a injini ya dizilo amafunika detergent yabwino yotenthetsera kutentha kwambiri.
