ʻO ka mea hoʻoheheʻe Diesel 095000-8981 Denso injector no Isuzu

1) Mai ka hiʻohiʻona o ka mīkini hana diesel kaʻina hana
Ua manaʻo ʻo Caprotti et al.!7 ma hope o ka pani ʻia ʻana o ka pahu kui o ka ʻenekini hoʻoheheʻe pololei ʻia, aia kahi wahi liʻiliʻi o ke koena diesel i loko o ka lua injection, a hoʻonui ka cylinder e hana i ka hana, e hopena i ka piʻi ʻana o ka mahana. i loko o ka cylinder, a hoʻolaha ka diesel i ka puka o ka puka hoʻoheheʻe a me ka injector wahie.Ma luna, ua hoʻokumuʻia kahi kiʻiʻaila wai;ʻo ke kiʻekiʻe o ka wela i loko o ke keʻena puhi ahi e hoʻoheheʻe ʻia nā ʻāpana wahie, a ke hele nei ka wahie i nā hopena ʻokiʻoki kiʻekiʻe e hana i nā waihona kalapona viscous;ʻo ka ʻūhū, hydrocarbons hoʻolapalapa kiʻekiʻe a me nā mea ʻaila lubricating i hana ʻia i ka wā o ka hoʻopau ʻana aia ma ka ʻili o nā waihona kalapona.ʻO ka hōʻiliʻili ʻana, ka nui o ka diffusion kiʻekiʻe o ka aila diesel, ka soot environment i loko o ke keʻena puhi ahi a me nā mea ʻē aʻe e hōʻoia i ka wikiwiki o ka hoʻokumu ʻana o ke kalapona;ʻO ka loaʻa ʻana o ka soot e hoʻokiʻekiʻe mau ai ka wela o ka piko o ka injector, e pale pono i ka hopena o ka wahie wai ma nā waihona kalapona.
2) Mai ka hiʻohiʻona o ka wehewehe elemental, Lepperhoff et al.ʻike ʻia ʻo nā mea nui o nā waihona kalapona he mau mea kūlohelohe (carbon, hydrocarbons, oxygen and nitrogen) a me kahi mea liʻiliʻi o nā mea inorganic (sulfur, ), ma o ka nānā ʻana o nā waihona kalapona;pā a me ka aila ʻO ke ala pili o nā droplets kahi kūlana kūpono no ke kūkulu ʻana i nā waihona kalapona.ʻO ka hapa nui o nā mea hoʻopili pili he hydrocarbons me nā wahi paila kiʻekiʻe.Hiki ke hoʻokaʻawale ʻia ke kaʻina hana o nā waihona kalapona i ʻelua mau kaʻina: ka wā induction a me ka wā ulu, e like me ka mea i hōʻike ʻia ma ka Figure 1. Ma waena o lākou: (1) I ka wā o ka hoʻokomo ʻana o ka waiho ʻana o ke kalapona, no ka haʻahaʻa haʻahaʻa o ka ʻili o ka pā. , Hoʻopili ʻia nā hydrocarbons me nā wahi paila kiʻekiʻe e hana i kahi kiʻiʻoniʻoni viscous ma ka ʻili o ka paia, a hoʻopili ʻia nā ʻāpana liʻiliʻi ma muli o ka hopena pepa paʻa;(2) I ka wā ulu o ka waiho kalapona, hoʻopili mau ʻia nā ʻāpana a me nā mea viscous ʻē aʻe.Piʻi ka mānoanoa o ka hoʻopaʻa kalapona a me ka hopena paipai e hoʻonui ai i ka wela o ka ʻili o ka hoʻopaʻa kalapona a emi ka ikaika hoʻopaʻa, e kaupalena ana i ka hoʻohui ʻana o nā mea ʻē aʻe.I ka manawa like, ke kahe o ke kinoea ke kumu Hoʻonui ka viscosity o ka waihona kalapona.Ke hoʻopili ʻia ka waihona kalapona i ka pā, ma lalo o ka mana o ka mahana wela lōʻihi, e hana ʻia nā hopena kemika e like me ka decomposition, dehydration, a me ka polymerization, a e hoʻopili hou ʻia ka papa waiho kalapona.
