ʻO wai ka maikaʻi?ʻEnekinia ʻElua a i ʻole ʻEnekini ʻEhā?

ʻElua ʻenekini kīkī a me ʻehā ʻenekini, ʻoi aku ka maikaʻi?I kēia lā ʻo Diingbo Power hui pū me ʻoe ma muli o ke kumu hana a me nā pono o lākou.

He aha ke kumu hana o ka ʻenekini diesel ʻelua-stroke?

ʻO ka ʻenekini diesel e hoʻopau ana i ka pōʻaiapuni hana ma o ʻelua paʻi ʻana o ka piston i kapa ʻia he ʻenekini diesel ʻelua.Hoʻopau ka ʻenekini ʻaila i ka pōʻaiapili hana a hoʻokahi wale nō hoʻololi ka crankshaft.Ke hoʻohālikelike ʻia me kahi ʻenekini diesel ʻehā-stroke, ua hoʻomaikaʻi ʻo ia i ka mana hana.Nui nō hoʻi nā ʻokoʻa ma ke ʻano o ka hoʻolālā kikoʻī a me ke kumu hana.

He aha nā mea maikaʻi o ka mīkini diesel ʻelua-stroke?

1. Ke hoʻohālikelike nā ʻāpana hana a me nā ʻāpana hana o ka engine diesel, e hoʻohālikelike i ko lākou mana, no nā ʻenekini diesel non-supercharged, ʻo ka mana hoʻopuka o kahi engine diesel ʻelua ma kahi o 60% -80% kiʻekiʻe ma mua o kēlā. he enegini diesel eha.Mai ka hiʻohiʻona o ka pōʻaiapuni kumu, ʻike ʻia he ʻelua-stroke diesel engine ʻelua ʻoi aku ka mana ma mua o ka ʻenekini ʻehā-stroke diesel .ʻO kaʻoiaʻiʻo, no ka loaʻaʻana o nā awa ea ma ka paia cylinder o ka engine dieselʻelua, ua ho'ēmiʻia ka hahau maikaʻi, ua nalowale ke kaʻina hana hoʻololi ea, a ua pau ka mana e hoʻokuʻu i ka pamu scavenging.Hiki ke hoʻonui ʻia ka mana e 60% -80%.

2. He mea maʻalahi ka hoʻolālā o ka mīkini diesel ʻelua-stroke, me nā ʻāpana liʻiliʻi a ʻaʻohe ʻāpana a i ʻole ʻāpana wale nō i loaʻa ke ʻano valve, kahi kūpono no ka mālama ʻana.

3. Ma muli o ka manawa pōkole o ka hahau mana, holo mālie ka mīkini diesel.Loaʻa i nā ʻenekini diesel ʻehā-stroke a me nā ʻenekini diesel ʻelua-stroke i kā lākou pono ponoʻī, a ʻokoʻa kā lākou noi i ka hana ʻana.Hoʻohana nui ʻia nā ʻenekini diesel ʻelua ma nā moku.

He aha ke kumu hana o nā ʻenekini diesel ʻehā?

ʻO ke kumumanaʻo hana o ka mīkini diesel ʻehā-stroke Ua hoʻopau ʻia ka hana o ka mīkini diesel e nā kaʻina hana ʻehā o ka intake, compression, combustion expansion and exhaust.ʻO kēia mau kaʻina hana ʻehā he pōʻaiapuni hana.ʻO ka mīkini diesel kahi e hele ai ka piston ma nā kaʻina hana ʻehā no ka hoʻopau ʻana i kahi pōʻaiapili hana i kapa ʻia he ʻenekini diesel ʻehā-stroke

He aha nā mea maikaʻi o ka ʻenekini diesel ʻehā-stroke?

1. Haʻahaʻa wela haʻahaʻa.Ma muli o ka manawa nui ma waena o nā kaha mana, ʻoi aku ka haʻahaʻa o ka haʻahaʻa wela ma ka piston, cylinder a me ke poʻo cylinder o ka mīkini diesel ʻehā-stroke ma mua o ka mīkini diesel ʻelua-stroke, e pale ana i ka luhi wela (e pili ana i nā ʻāpana. pōʻino ma muli o ka loaʻa ʻana o ka wā lōʻihi i nā wela kiʻekiʻe, e hopena i ka hoʻohaʻahaʻa ʻana i nā waiwai mechanical) ʻoi aku ka maikaʻi ma mua o nā mīkini diesel ʻelua-stroke.

2. ʻOi aku ka maikaʻi o ke kaʻina hana hoʻololi ea ma mua o ka mīkini diesel ʻelua-stroke, ua hoʻokuʻu ʻia ke kinoea hoʻopau maʻemaʻe, a ʻoi aku ka maikaʻi o ka hoʻouka ʻana.

3. Ma muli o ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, maʻalahi ka hoʻohana ʻana i ka turbocharging exhaust gas e hoʻonui i ka mana o ka mīkini diesel.

4. Hoʻokō waiwai maikaʻi.Ma muli o ke kaʻina hana hoʻoheheʻe kūpono a me ka hoʻohana piha ʻana i ka ikehu wela, ua haʻahaʻa ka nui o ka wahie.Ma muli o nā hiʻohiʻona hoʻolālā, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana i ka aila lubricating o ka mīkini diesel ʻehā.

5. ʻOi aku ka maikaʻi o nā kūlana hana o ka ʻōnaehana wahie.No ka mea, hoʻokahi wale nō hoʻoheheʻe wahie i ka crankshaft i kēlā me kēia ʻelua hoʻololi ʻana, ʻoi aku ka lōʻihi o ke ola lawelawe o ka pālua plunger o ka paila jet ma mua o ka mīkini diesel ʻelua-stroke.He haʻahaʻa ka haʻahaʻa wela o ka nozzle jet i ka wā o ka hana a he liʻiliʻi nā hemahema.

I loko o ka ʻenekini diesel ʻehā, lawe ka piston i ʻehā mau paʻi e hoʻopau ai i kahi pōʻaiapili hana, ʻelua mau paʻi (intake a exhaust), ua like ka hana o ka piston me kahi pamu ea.I loko o kahi ʻenekini diesel ʻelua-stroke, kēlā me kēia hoʻololi o ka crankshaft, ʻo ia hoʻi, ʻo kēlā me kēia ʻelua paʻi o ka piston e hoʻopau i kahi pōʻai hana, a ua hoʻopau ʻia nā kaʻina hana intake a me ka hoʻopau ʻana e ka ʻāpana o ka hoʻopiʻi a me ke kaʻina hana, no laila ka piston o ka. ʻaʻole ʻo ka ʻenekini diesel ʻelua-stroke ʻO ke kuleana o ka paila ea.

Ma muli o ka ʻokoʻa o ka nui o nā paʻi i kēlā me kēia pōʻai hana o nā ʻano ʻenekini diesel ʻelua, a me nā ʻano like ʻole o ka hoʻololi ʻana i ka ea, loaʻa iā lākou ko lākou ʻano ponoʻī ke hoʻohālikelike ʻia me kekahi.Akā ʻo ka mea holoʻokoʻa he ʻehā-stroke engine maʻalahi e hoʻohana.I kēia mau lā, ʻo ka hapa nui o nā ʻenekini diesel o ka generator set he ʻehā mau kī.Ke hoʻohālikelike ʻia me ka ʻenekini ʻelua-stroke, ua loaʻa i ka ʻenekini ʻehā haʻahaʻa wahie hoʻohana , hana hoʻomaka maikaʻi a haʻahaʻa haʻahaʻa haʻahaʻa.
