ʻO ka mea hoʻoheheʻe wahie maʻamau hou F00RJ01683 Hui Pū ʻIa Mana no ka Injector 0445120080 0445120268

Ka helu helu a me nā haʻawina hoʻokolohua e pili ana i ka solenoid common rail diesel injector me ka pahu hoʻomalu ʻeleʻele(ʻāpana 1 )

ʻĀpana.

Ua hoʻomohala ʻia ke kumu hoʻohālike makemakika o kahi solenoid common rail fuel injector. ʻO kona ʻokoʻa mai nā hiʻohiʻona e kū nei ʻo ka control valve wear simulation. Ua hoʻohana ʻia kahi mea hoʻokele kaʻa maʻamau o 0445110376 Series (Cummins ISf 2.8 Diesel engine) i hana ʻia e Bosch Company ma ke ʻano he mea noiʻi. Ua hoʻoholo ʻia nā ʻāpana injector (ka lawe ʻana i ka wahie a me ka leakage hope) e ka helu ʻana a me nā ʻano hoʻokolohua. ʻO ka awelika ʻo GT-Suite R2 he 0.93, ʻo ia hoʻi, wānana pololei ʻo ia i ke ʻano o ka nui o ka injection (nominal a marginal technical conditions of a injector). Ua hōʻike ʻia ka ʻike helu helu a me nā haʻawina hoʻokolohua e hoʻonui ana ka hoʻohana ʻana i ka valve control i ka leakage hope a me ka lawe wahie (ʻoi loa ma 160 MPa). Ua hoʻomohala ʻia nā hiʻohiʻona regression no ka hoʻoholo ʻana i ka hāʻawi wahie a me nā hopena leakage hope ma ke kaomi wahie a me ka manawa hoʻoikaika (no nā kūlana ʻenehana nominal a marginal).

ʻO ka hapa nui o nā kaʻa hou me nā ʻenekini diesel ua lako me nā ʻōnaehana hoʻoheheʻe wahie maʻamau. Kōkua lākou i ka hoʻokō ʻana i nā koi koʻikoʻi no ka nui o ka hoʻokuʻu kinoea. Hiki kēia ma muli o ke kiʻekiʻe o ke kaomi wahie (a hiki i 300 MPa) a me ka hoʻohana ʻana i ka wahie biodiesel [1-4]. ʻO nā mea hoʻokomo wahie kaʻa maʻamau ka mea nui loa o ka ʻōnaehana [5]. Hāʻawi lākou i ka hāʻawi wahie i loko o nā cylinders me ka pololei kiʻekiʻe ma muli o ke ʻano hana ʻenekini. ʻElua ʻano o ka injectors - me ka piezo actuators a me solenoid actuators [6-8]. Loaʻa i kēlā me kēia o lākou kekahi mau pono a me nā hemahema [9]. ʻO ke ʻano o ka injector i hoʻohana ʻia, pono e hāʻawi ʻia ka pololei kiʻekiʻe o ka lawe ʻana i ka wahie no ka manawa lōʻihi. Hoʻololi nā kūlana ʻenehana o kahi ʻōnaehana hoʻoheheʻe wahie maʻamau me ka piʻi ʻana o ka mile kaʻa [10].
