Kafukufuku pa Mphamvu ya Kusuntha kwa Valve ya Singano ya Injector ya Dizilo pa Makhalidwe a Jakisoni wa Bowo Lililonse. (gawo 1)
Pamene malamulo oyendetsera mpweya ndi mafuta akuchulukirachulukira, ma injini oyatsira mkati akupitilizabe kupita kumalo aukhondo, abwino komanso opulumutsa mphamvu. Malamulo okhwima otulutsa mafuta amaika patsogolo zofunika kwambiri pamakina operekera mafuta, ndipo kuthamanga kwa jakisoni wamafuta kumatha kufika pafupifupi 250MPa kapena kupitilira apo. Mkulu-anzanu wamba njanji wakhala ambiri m'munda wa injini dizilo chifukwa cha luso lapadera ubwino, ndi jekeseni mafuta, monga actuator terminal kulumikiza kumtunda mkulu-anzanu wamba njanji ndi mtsinje mafuta jekeseni, ndi zodziwikiratu. Banja la singano la singano silimangogwira ntchito ya mafuta odzola, kusindikiza ndi kuzungulira, komanso limagwiranso ntchito ngati gawo lachindunji la jekeseni wamafuta, lomwe limatsimikizira mawonekedwe a jekeseni wamafuta ndi kupopera, ndiyeno zimakhudza khalidwe losakanikirana lamafuta ndi gasi. umuna makhalidwe.
Gulu la singano la singano limapangidwa ndi valavu ya singano ndi thupi la singano. Ndi kuwonjezeka kosalekeza kwa kuthamanga kwapamwamba kwa jekeseni wa njanji, kuthamanga kwa mafuta othamanga kwambiri mumphuno (wopangidwa ndi gulu la singano la valve, chipinda choponderezedwa, ndi zina zotero) osati kungokhala ndi chiwerengero cha Reynolds chapamwamba Kugwedezeka kwachangu kwa jet. amatsagana ndi cavitation chifukwa pulse contraction ndi madzimadzi vortex kuyenda, kupanga zovuta mpweya-zamadzimadzi awiri-gawo otaya, amene amakhudza mafuta atomization khalidwe. kumapeto kwa dzenje la nozzle. Kutengera izi, kuchokera pakuwona kuyenda kwakanthawi kwa valavu ya singano, pepalali limasanthula chikoka cha kusuntha kwanthawi zonse (popanda kuganizira za eccentricity) ndi kusuntha kosakhazikika (poganizira eccentricity) ya valavu ya singano pamayendedwe amkati ndi mawonekedwe a jekeseni wa aliyense. dzenje, ndikupanga njira yomwe imaganizira kupsinjika kwamafuta amafuta. Kutengera mtundu wa gasi wokhala ndi magawo awiri a transonic otuluka mumphuno, zomwe zimapangitsa kuti pakhale zotanuka komanso kusuntha kwa valavu ya singano zimafufuzidwa, zomwe zimapereka maziko amalingaliro okhathamiritsa mapangidwe ndi kupanga jekeseni.
