Hoʻolauna huahana:
Hoʻokomo ka ʻōnaehana hoʻoheheʻe diesel i ka wahie a puʻunaue i waena o nā ʻāpana e hui pū me ka ea i loko o ke keʻena puhi.
Hoʻokumu nui ʻia ia me kahi mea hoʻoheheʻe wahie a me kahi kino injector.Hoʻokaʻawale ʻia nā injectors wahie i kau ʻia ma ke poʻo cylinder i ʻelua ʻano: ʻano wehe a me ke ʻano pani.He ʻano maʻalahi ka injector hāmama akā ʻino ka atomization a ʻaʻole hoʻohana ʻia.Hoʻohana nui ʻia nā injectors wahie pani i nā ʻenekini diesel like ʻole.Hoʻomoʻa ka ʻenekini diesel i ka ea maʻemaʻe i ka wā o ka intake stroke.I ka wā e kokoke ana ka hahau hoʻoemi ʻana i ka hopena, hoʻonui ʻia ka ʻaila diesel i ʻoi aku ma mua o 100MPa e ka pauma hoʻoheheʻe wahie, hoʻokomo ʻia i loko o ka cylinder ma o ka injector wahie, a hui pū ʻia me ka ea wela kiʻekiʻe i hoʻopaʻa ʻia i ka manawa pōkole loa e hana i kahi. huihuʻi puhi.Ma muli o ke kiʻekiʻe compression ratio o nā mīkini diesel (maʻamau 16-22), hiki i ke ea kaomi i loko o ka cylinder ke hiki i 3.5-4.5MPa i ka hopena o ka hoʻopiʻi ʻana, a ʻo ke kiʻekiʻe o ka mahana e like me 750-1000K (ʻoiai ke kaomi kinoea hui ʻana. ʻO nā engines gasoline i kēia manawa e 0.6-1.2MPa , hiki i ka mahana ke 600-700K), kahi iʻoi aku ma mua o ka mahana wela o ka diesel.No laila, ma hope o ka hoʻokomo ʻia ʻana o ka wahie diesel i loko o ka cylinder, e hoʻā koke a ʻā iā ia iho ma hope o ka hui ʻana me ka ea i ka manawa pōkole loa.Piʻi wikiwiki ka ea i loko o ka cylinder i 6-9MPa, a piʻi pū ka mahana i 2000-2500K.Ke alakaʻi ʻia e ke kinoea piʻi kiʻekiʻe, neʻe ka piston i lalo a hoʻokele i ka crankshaft e hoʻololi e hana i ka hana, a hoʻokuʻu pū ʻia ke kinoea hoʻopau i ka lewa ma o ka paipu hoʻopau.
Hoʻokele ʻia ka ʻenekini diesel maʻamau e ka ʻenekini camshaft, a hāʻawi ʻia ka ʻaila diesel i ke keʻena wahie o kēlā me kēia cylinder ma o kahi ʻaila ʻaila kiʻekiʻe.Pono e hoʻololi kēia ʻano hoʻolako ʻaila me ka hoʻololi ʻana i ka wikiwiki o ka ʻenekini, a ʻaʻole hiki ke hoʻokō ʻia ka nui o ka hoʻolako ʻana i ka aila ma nā ʻano wikiwiki.ʻO ka ʻōnaehana hoʻolako wahie hoʻoheheʻe kaʻa maʻamau i loko o ka pauma wahie kiʻekiʻe, ka paipu wahie maʻamau, ka wahie injector, ka mana uila (ECU) a me kekahi mau mea ʻike paipu.Hoʻopili ʻia kēlā me kēia wahie injector i loko o ka ʻōnaehana i ka hoʻolako wahie maʻamau ma o kāna paipu wahie kiʻekiʻe.Hoʻopili ʻia nā paipu, a ʻo ka paipu hāʻawi wahie maʻamau e hana ma ke ʻano he hydraulic pressure accumulator no ka injector.I ka hana ana, ke kiʻekiʻe-puʻi wahie pauma hāʻawi wahie i ka lehulehu wahie lako paipu ma kiʻekiʻe puʻe, a me ka kiʻekiʻe-puʻe wahie pauma, puʻe kiʻi a me ECU hana i pani-loop hana e precisely kaohi i ka aila puʻe i loko o ka lehulehu wahie lako. paipu, hoʻololi loa i ke kaomi ʻaila me ka hoʻololi ʻana i ka wikiwiki engine.Phenomenon.ʻO kāna mau hiʻohiʻona nui e like me kēia:
1. Hoʻokaʻawale loaʻia ka manawa hoʻolālā wahie mai ka mīkini mīkini, a ke hoʻomaluʻia ka'eneʻena a me ke kaʻina hana wahie e ka ECU i ka manawa.
2. Hiki ke hoʻololi i ke kaomi wahie o kēlā me kēia cylinder, ka hoʻomaka ʻana a me ka lōʻihi o ka wahie e like me nā kūlana hana o ka ʻenekini, i mea e alualu ai i ka wahi mana maikaʻi loa o ka wahie.
3. Hiki ke hoʻokō ʻia ke kaomi wahie kiʻekiʻe a me ka pre-injection o ka diesel.
