Dizilo Injector Fuel Injector 095000-8730 Denso Injector for Shangchai, Toyota, Hyundai, Mitsubishi Fuso

Poyerekeza ndi kafukufuku experimental, kayeseleledwe manambala ndi okhwima, kotero manambala kayeseleledwe njira ndi njira yothandiza kuphunzira cavitation otaya mu jekeseni wa mkulu kuthamanga dizilo injini, ndipo angapereke mfundo zofunika kafukufuku. Pakadali pano, akatswiri apanga kafukufuku wokhudza momwe ma cavitation amapangidwira mkati mwa jekeseni wa dizilo pogwiritsa ntchito njira yoyeserera manambala, kutsata mitundu yosiyanasiyana ya mawerengedwe a cavitation, geometry ya nozzle, magwiridwe antchito ndi zinthu zina, ndipo apanga kafukufuku wofunikira. Zitha kupezeka kuchokera ku zitsanzo izi kuti khoma losalala limatengedwa kuti ligwiritsidwe ntchito pakhoma. Ndipotu khoma lamkati la mphuno ndi khoma lolimba. Chifukwa cha kuthamanga kwambiri komanso kuthamanga kwambiri kwamadzimadzi mu jekeseni, padzakhala kupsyinjika kwakukulu kwa kukameta ubweya pafupi ndi khoma lolimba, zomwe zidzabweretse kusokoneza kwina kwa liwiro ndi kuthamanga. Komabe, chikoka limagwirira wa chisokonezo ichi pa cavitation otaya makhalidwe mu jekeseni si bwino. Pokhazikitsa chitsanzo chololera cha masamu kuti ayese kutuluka kwa cavitation mkati mwa jekeseni wa dizilo, magawo opanda malire monga cavitation parameter K ndi mafunde a coefficient Cd amagwiritsidwa ntchito pofotokoza makhalidwe a cavitation otaya mkati mwa nozzle, ndi chikoka cha roughness pakhoma pakuyenda kwakukulu, kugawa gasi gawo ndi kugawa liwiro mkati mwa nozzle amawerengedwa.

1) Pamene kulowetsedwa kwa cholowera kumakhala kochepa, kutsika kwapakati kumachepa ndi kuwonjezeka kwa roughness; Pamene kulowetsedwa kolowera kuli kwakukulu, chikoka cha roughness pa otaya coefficient ndi ochepa.

2) Kuthamanga kwapakati kumawonjezeka pang'onopang'ono ndi kuwonjezeka kwa parameter ya cavitation. Pamene chizindikiro cha cavitation ndi chachikulu kuposa mtengo wina, kuthamanga kwa coefficient sikumasinthanso ndi parameter ya cavitation.
