ʻO ka mea mua, ka mana o ke kahe wai hoʻoluʻu: lawa ʻole ka wai anuanu.Thermostat hairpin, malfunction.Ua pōʻino ka pama a i ʻole e paheʻe ke kāʻei conveyor, e hana maikaʻi ʻole ai ka pama.
ʻElua, ʻo ka mana o ka hiki ke hoʻoheheʻe wela i ka mahana o ka wai: radiator, cylinder, cylinder head water jacket waiho nui loa, hoʻemi i ka hana hoʻoluʻu wai.A ʻo ka nui o ka nui o ka waiho ʻana i loko o ka ʻaʻahu wai e hoʻemi ʻia ka ʻāpana pipeline e hoʻemi ʻia, no laila e hoʻemi ʻia ka nui o ka wai e komo ana i ka pōʻai hoʻomaha, a laila e hōʻemi ana i ka absorption o ka cylinder block. wai hooluolu.ʻOi aku ka liʻiliʻi o ka mana radiator, liʻiliʻi loa ka wahi hoʻoheheʻe wela, e pili ana i ka hopena wela, e hopena i ka wela o ka wai.
ʻEkolu, ka mana o ka hoʻouka ʻana o ka ʻenekini i ka wela o ka wai.ʻAʻole hana maikaʻi ka mīkini diesel.Overload no ka manawa lōʻihi ma haʻahaʻa māmā holo, i ka diesel engine overheating, kumu excessive wai wela.
Nā kumuwaiwai:
ʻO nā mea maikaʻi o nā mīkini diesel he torque nui a me ka hana waiwai maikaʻi.ʻO ke kaʻina hana o ka ʻenekini diesel he nui nā mea like me ka mīkini ʻaila.ʻO kēlā me kēia pōʻaiapili hana e hele pū i nā ʻehā ʻehā: intake, compression, power and exhaust.Akā, no ka mea, he diesel wahie, kona viscosity ua nui ma mua o ka petrola, 'aʻole maʻalahi e evaporate, a me kona spontaneous combustion wela mea haʻahaʻa ma mua o gasoline, no laila, i ka hoʻokumu a me ka ignition o combustible hui 'okoʻa mai ka gasoline engine.
ʻO ka ʻokoʻa nui ʻo ia ka hui ʻana i loko o ka cylinder o kahi mīkini diesel i hoʻopaʻa ʻia ma mua o ka puhi ʻia.Ke hana ka ʻenekini diesel, komo ka ea i ka cylinder.Ke hoʻopili ʻia ka ea i loko o ka cylinder a hiki i ka hopena, hiki i ka mahana ke hiki i 500-700℃a hiki i ke kaomi ke hiki i 40-50 mau ea.
Ke kokoke ka piston i ke kikowaena make o luna, hoʻokomo ka nozzle injector o ka ʻōnaehana hoʻolako aila i ka wahie i loko o ke keʻena puhi pahu cylinder ma ke kaomi kiʻekiʻe loa i kahi manawa pōkole loa.Hoʻokumu ka ʻaila diesel i nā ʻāpana ʻaila maikaʻi, i hui pū ʻia me ka ea o ke kaomi kiʻekiʻe a me ke kiʻekiʻe kiʻekiʻe.ʻO ka hui pū ʻana e puhi wale ʻia, a ua hoʻokumu ʻia ka ikaika pahū e ka hoʻonui ikaika, e koi ana i ka piston e hana i lalo.ʻO ke kaomi a hiki i ka 60-100 atmospheres a he kiʻekiʻe loa ka torque, no laila ua hoʻohana nui ʻia ka mīkini diesel i nā lako diesel nui.
ʻO nā hiʻohiʻona o ka mīkini diesel kuʻuna: ʻoi aku ka maikaʻi o ka wela a me ka hoʻokele waiwai, hoʻohana ka ʻenekini diesel i ka ea i hoʻopaʻa ʻia e hoʻomaikaʻi i ka mahana o ka ea, i ʻoi aku ka mahana o ka ea ma mua o ka wahi hoʻoheheʻe ʻia o ka wahie diesel, a laila hoʻokomo ʻia i loko o ka wahie diesel, ʻūhā diesel. a hui pū ka ea i ka manawa like i ko lākou puhi ahi.ʻO ka hopena, ʻaʻole pono nā ʻenekini diesel i kahi ʻōnaehana hoʻāla.
I ka manawa like, ʻoi aku ka maʻalahi o ka ʻōnaehana hoʻolako wahie diesel, no laila ʻoi aku ka maikaʻi o ka hilinaʻi o nā mīkini diesel ma mua o nā ʻenekini.He kiʻekiʻe koʻikoʻi ka ʻenekini diesel no ka mea ʻaʻole i kaupalena ʻia e ka deflagration a me ka pono o ka puhi ʻana i ka diesel.ʻOi aku ka maikaʻi o ka thermal a me ka hoʻokele waiwai ma mua o ka mīkini ʻaila, i ka manawa like i ke ʻano o ka mana hoʻokahi, ʻoi aku ka nui o ka torque diesel engine, haʻahaʻa ka wikiwiki o ka mana, kūpono no ka hoʻohana ʻana i nā kaʻa.
