2-stroke engine

E aʻo i nā neʻe 2-bar ʻekolu

Pehea ia hana?

ʻO Champion of speed, cross, enduro and even trial, ʻike ka ʻenekini 2-stroke pehea e hana ai i nā mea āpau. Pehea ʻo ia e hoʻokō ai i kēia hana? I kēia pule, hoʻoikaika ʻo Biker Repair iā ʻoe e ʻike i ka ʻōpū o kēia pumehana inveterate akā ʻaʻole hiki ke hoʻololi ʻia e hoʻomaopopo pono iā ia.

Mālama kēia KTM ʻelua-stroke i ka lako mana carburetor maʻalahi. I ka wā e hiki mai ana, e hoʻololi ʻo ia me kahi hoʻomaʻemaʻe a ʻoi aku ka maikaʻi.

Loaʻa ka 2-stroke i hoʻokahi puhi ʻana i kēlā me kēia hahau. ʻO kahi pōmaikaʻi nui ma luna o kahi 4-stroke, hiki iā ia ke hāʻawi i ka manaʻo ʻelua i ka mana ma ka neʻe like. ʻO kahi hiʻohiʻona e hāʻawi iā ia i ka maʻalahi, loaʻa kālā a ʻike ʻia i nā hoʻokolohua. E like me kāu e ʻike ai mai kā mākou pahu, 2 mau paʻi e hana i 2 mau mea i ka manawa (ma luna a ma lalo o ka piston), akā naʻe, hoʻohui iki i nā pulupulu. ʻOiaʻiʻo, hiki iā ia ke komo i nā kinoea hou i loko o nā kinoea hoʻopau. He kīnā e hoʻohaumia ai a ʻai nui. Akā, e like me kā mākou e ʻike ai ma hope, ʻaʻole pāpā ʻia kēia hemahema, ʻoiai ʻoiai he mau ʻano ʻē aʻe kekahi.

Maʻalahi a māmā

ʻAʻohe valve maʻaneʻi, akāʻo ka "māmā" i loaʻa iā ia ka inoa kapakapa "cylinder bore". ʻO ka hele ʻana o ka piston i mua o nā kukui e hōʻoiaʻiʻo i ka hāʻawi ʻana, no laila e pale aku ai i ka hoʻohana ʻana i hoʻokahi a ʻoi aku paha nā camshafts i alakaʻi ʻia e kahi kaulahao i hoʻolako ʻia me nā tensioners, nā kīwī āpau āpau ma o nā pali a i ʻole nā ​​tappets. ʻO nā ʻāpana ʻāpana e hoʻemi loa i nā kumukūʻai hana e like me ka mālama ʻana a me ke kaumaha. ʻO nā hiʻohiʻona e lilo ai ia i poʻokela hoʻokūkū.

ʻO ka ʻenekini o ka wā e hiki mai ana!

Me ka injection, ka mea e hoʻouna i ka wahie i loko o ka cylinder wale nō ma hope o ka pani ʻana o ke kinoea hoʻopau, pale ʻia ke kinoea hoʻopau mai ka nalowale ʻana o ke kinoea hou. Hoʻokaʻawale ʻia ka pollution a me ka ʻai ʻana e 2, a hiki i nā pae o nā mīkini 4-stroke o kēia manawa ʻoiai e mālama ana i ko lākou mau pono kūlohelohe. Hoʻohana ʻia kēia ʻenehana e Rotax ma kā lākou 600 a me 800 Skidoo twin-cylinders (kiʻi), e hoʻomohala ana i 120 a me 163 hp. ma 8000 rpm, kēlā me kēia. ʻAʻohe mea a mākou e ʻōlelo ai, ʻaʻole ʻōlelo ka lua i kāna ʻōlelo hope !!!

Pahu

2 paʻi a me 3 neʻe

Loaʻa kēia inoa i ka lua-stroke no ka mea e hana ana i nā ʻanuʻu 4 o kāna pōʻai ... i 2 mau ʻanuʻu. Loaʻa iā ia kēia hana ma ka hana like ʻana ma luna a ma lalo o ka piston. E nānā pono kākou i ka hana ʻana o kēia.

Kiʻi # 1:

(Ma luna o ka piston): ʻO ka hoʻokiʻekiʻe ʻana i ka piston e hoʻopaʻa i ka hui. ʻO kēia ka pae hoʻoemi.

(Ma lalo o ka piston): I ka manawa like, hoʻonui ka neʻe ʻana o ka piston i ka nui o ka pahu crankcase. No laila, hoʻomohu ke kaumaha i ka hui ʻana ma o nā kiwi. ʻO kēia ka pae ʻae.

Kiʻi # 2:

(Ma luna o ka piston): Ua hiki ka piston i ka piko o kāna hahau. Aia ʻo ia ma High Still, a i ʻole PMH. Hoʻomaka ka ʻulaʻula mai ka pahu ahi i ka ʻā a hoʻomaka ka piston e iho. ʻO kēia ka manawa puhi.

(Ma lalo o ka piston): Aia ka nui o ka pahu crankcase i kona kiʻekiʻe a pau ka intake. Ma ke ʻano maʻamau, ua lako ʻia nā manawa ʻelua me kahi inlet casing haʻahaʻa a nānā i nā kiwi, e like me kēia, e pale i ka hoʻokuʻu ʻana o nā kinoea hou i loaʻa.

Kiʻi # 3:

(Ma luna o ka piston): Hoʻonui ka puhi ʻana i ke kaomi a me ka mahana. Hoʻonui nā kinoea a hoʻohaʻahaʻa i ka piston. ʻO kēia ka pae hoʻokele o ka pōʻai, i kapa ʻia hoʻi ka hoʻomaha. I ka wehe ʻana o ke kukui hoʻopau (hema), hāʻule ke kaomi, a laila hoʻomākaukau i ke komo ʻana o nā kinoea hou i hoʻopaʻa mua ʻia i loko o ka hale haʻahaʻa.

(Ma lalo o ka piston): E emi ana ka leo o ka pahu crankcase, ka mea e pani ai na kiwi a ua hoopili mua ia na kinoea hou (maomao). ʻO ka wehe ʻana i nā kukui uila e wehe koke i nā kinoea hou mai ka cylinder. Ua ʻike ʻia ʻo ka puka ākea ākea e hiki ai i kekahi mau kinoea ke pakele mai ka ʻenekini me ke ahi ʻole. Ua kapa ʻia e ka poʻe akamai he "kaapuni pōkole"
