Me ka hoʻomau mau ʻana o ka pae hoʻokuʻu ʻana i ka pollutant control, ʻo ka hapa nui o nā ʻenekini diesel i kēia manawa e hoʻohana nei i ka uila uila kiʻekiʻe-pressure maʻamau ʻōnaehana wahie maʻamau, ʻōnaehana ʻōnaehana mai 1600bar a 2500bar, electronically controlled fuel injector ka mea nui loa o ka uila holoʻokoʻa. ʻO ka ʻōnaehana wahie kaʻa maʻamau, ka paʻakikī a me ka paʻakikī ka mea nui loa. Hoʻokuʻu ʻo ECU i ka solenoid valve o ka injector e wehe i ka wikiwiki kiʻekiʻe. ʻO ka nui o ka hoʻoheheʻe wahie e pili ana i ka manawa mana o ka valve solenoid, ke kaomi injection, ke anawaena o ka nozzle a me nā mea ʻē aʻe. Ma muli o ka pane koke ʻana o ka injector kaʻa maʻamau kiʻekiʻe, ua lilo ka nui o ka injection i kekahi o nā hiʻohiʻona nui loa o ka ʻōnaehana wahie maʻamau.

ʻO ka pahu injector solenoid valve ka mea nui o ka ʻōnaehana mana uila diesel, kona ikaika electromagnetic a me ka hiki ke pane wikiwiki e hoʻopili pololei i ke kaomi injection a me ka pololei injection.

Hoʻopili nui ʻia ka ikaika electromagnetic static o ka valve solenoid e ka hoʻokele ʻana i kēia manawa, ka hoʻomaʻemaʻe hana, ka huli ʻana o ka coil, ka mea magnetic core, ka wahi pole magnetic i loko a i waho electromagnet, ka mānoanoa armature a me nā mea ʻē aʻe. ʻO nā ʻāpana hoʻokele i hōʻike ʻia e ka hoʻokele o kēia manawa, nā ʻāpana hui i hōʻike ʻia e ka hana ʻana i ka ea a me ka damping gap, a ʻo nā ʻāpana hoʻonohonoho i hōʻike ʻia e nā huli coil nā ʻāpana koʻikoʻi e pili ana i ka ikaika electromagnetic o ka solenoid valve.

I ka emi ʻana o ke kaʻa kaʻa ma mua o 4A, liʻiliʻi ka liʻiliʻi o ka solenoid valve, ʻaʻole maʻalahi nā mea magnetic maʻalahi e hana i kahi hanana saturation magnetic, ʻo ka hoʻokele ʻana i kēia manawa ke kumu nui e pili ana i ka hoʻololi ʻana i ka ikaika electromagnetic. Ke ʻoi aku ka nui o ke kaʻa kaʻa ma mua o 4A, ʻoiai ʻo ka piʻi ʻana o ka flux holoʻokoʻa ke kumu nui no ka hoʻonui ʻana i ka ikaika electromagnetic, ʻo ka piʻi ʻana o ka holo ʻana o ka valve solenoid e hoʻonui i ka emi ʻana o ka ikaika electromagnetic, e alakaʻi ana. i ka emi ana o ka ikaika electromagnetic o ka solenoid valve.
