Ma ke kaʻina hana maoli o ka injector, ʻaʻole pili wale ka kahe kahe o ka nozzle e ka neʻe ʻana o ka valve needle, akā ma ke ʻano o ke kahua kahe i loko o ka nozzle. No ka mīkini diesel, hoʻopili pololei ka mea hoʻoheheʻe wahie i loko o ka cylinder, a ʻo ka haʻahaʻa wela kiʻekiʻe a me ka hoʻololi nui o ke kaomi ambient e hoʻololi i ka neʻe ʻana o ka valve needle a me ka cavitation ma ka puka o ka nozzle. A no ka paʻakikī loa o ka hana o ka wahie injector, ua hōʻike pololei ʻia i ke keʻena kuni, a ʻo nā waiho kalapona i hana ʻia e ka oxidation a me ka polymerization o ka ʻaila kiʻi ma ka puka nozzle e hōʻiliʻili i ka puka nozzle, e hopena i kahi loli. i ka huina kahe a pili i ke ola kino o ka wahie injector. No laila, ʻo ka ʻike koke ʻana i ka nānā ʻana ma ka laina o ka coefficient kahe nozzle o ka injector i ka wā o ka neʻe ʻana o ka valve needle hiki ke hoʻokō pono i ka loiloi olakino a me ka hōʻoia hewa o ka injector, a hāʻawi i kumu no nā hoʻolālā hoʻokele waiwai nui.
no ke kuhikuhi ana.
Ma nā ʻāpana like ʻole o ka neʻe ʻana o ka neʻe ʻana o ka nila, aia nā ʻokoʻa nui i ka coefficient kahe o ka nozzle. Ke hoʻomau mau ʻia ka valve nila ma ke kūlana hoʻokiʻekiʻe kiʻekiʻe, e hoʻomau mau ʻia ka wahi kahe kūpono o ka nozzle i ke kūlana o ka nui o ka kahe kahe, a ʻaʻole loli ka nui o ka wahie, ʻoiai ke hoʻololi nui ʻia ka coefficient kahe o ka nozzle i ka wā o ka nila. wehe ʻia ka valve a noho. ʻO ka maʻamau, ʻo ka manawa injection hoʻokahi e pili ana i 1ms, a ʻo ka valve needle ka hapa nui ma kahi neʻe ʻana ma mua o ka palena kiʻekiʻe.
