Kiʻekiʻe DLLA145P864 no Denso Common Rail Nozzle Diesel Engine Spare Parts

ʻO nā ʻenehana ʻenehana nui ʻelua i ka hoʻomohala ʻana i ka ʻenehana mīkini diesel e pili ana i ka ʻōnaehana wahie.ʻO ka hoʻohana ʻana i ka ʻenehana hoʻokele uila i manaʻo ʻia he mea nui i ka hoʻomohala ʻana i ka ʻenehana mīkini diesel.

ʻO nā ʻāpana nui o ka injector wahie he solenoid valve, control valve, piston a me nā ʻāpana ʻāpana o ka nila.Lawe ʻia ka wahie piʻi kiʻekiʻe e ka paipu kaʻa maʻamau.ʻElua mau ala lawe wahie i loko o ka injector wahie, hele kekahi i loko o ke keʻena hoʻomalu ma luna o ka piston mana a ʻo kekahi e hele i loko o ke keʻena accumulator ma ka piko o ka valve needle.Ke hoʻoikaikaʻoleʻia ka valve solenoid, ua paniʻia ka pukaʻaila i loko o ka lumi hoʻomalu.No ka mea, ʻoi aku ka nui o ka ʻāpana cross-sectional o ka piston control ma mua o ka ʻāpana o ka ʻili o ka neʻe valve conical pressure surface, i hui pū ʻia me ka ikaika preloading o ka pūnāwai piston, ua paʻa paʻa ka valve nila ma ka ʻili o ka noho;Ke loaʻa i ka valve solenoid ka hōʻailona hoʻomalu a pili ʻia, ua wehe mālie ʻia ka puka puka ʻaila, i kēia manawa, e emi mālie ka ʻokoʻa kahe o ka wahie i loko o ke keʻena hoʻomalu, nāwaliwali ke kaomi wai ma ka piston, e hoʻemi mālie ʻia ka valve needle. piʻi, kahe ka wahie i loko o ke keʻena kaomi nozzle ma hope o ka lua hoʻoheheʻe, ka hoʻokumu ʻana o ka wahie.Ke hoʻemi ʻia ka mana o ka solenoid valve, ka ikaika electromagnetic, ʻaʻole lawa ke kaomi hydraulic e lanakila ai i ka ikaika preload puna a hana i ka valve needle e noho hou, ka hopena o ka ʻaila ʻaila.
