ʻEkolu pahu

He aha inā inā he moto ENGINE par excellence?

I ka wā ma mua, ua ʻike mākou i ka 3-cylinder 2-stroke, ma ka pūnaewele ma Kawasaki, Suzuki a me Motobécane, a i ʻole V-like ma Honda. ʻO ka ʻoiaʻiʻo, no Honda, he mau motika laina kēia, ua hoʻopololei ʻia nā cylinders e loaʻa ai ka laulā. Hoʻokahi wale nō koʻokoʻo hoʻohui i kēlā me kēia manequin, a ʻo kēlā me kēia cylinder i kona pahu pahu kūʻokoʻa kūʻokoʻa. Ua lako keia mau enekini me 400 alanui PSA a me 500 RS a me NS GP. ʻO kahi kikoʻī ʻakaʻaka, ua hoʻohuli ʻia nā hoʻolālā i hoʻohana ʻia: 2 pahu pahu a me kahi kū pololei ma ke alanui, ʻo ka ʻaoʻao ma GP. Malia paha ma nā pilikia e pili ana i ka hele ʻana o nā ipu hoʻomaha a me ka wela i hoʻokuʻu ʻia ...

ʻO ka pōkole, ʻekolu mau pahu pahu i kēia mau lā he mau ʻenekini makani i loko o kā lākou peʻa, akā like lākou a pau i ka hoʻolālā like: he ʻenekini in-line a ʻoiaʻiʻo he pōʻai 4-stroke, no ka mea, ʻaʻohe makani i loko o ka lua-stroke. kona mau pea...

Hoʻokahi no nā mea a pau, a pau ma ka pūnaewele!

No ka calibration maikaʻi loa e pili ana i ka vibration a me ka maʻamau cyclical, hoʻonoho ʻia ka pahu pahu i kēlā me kēia 120 ° no ka hana maʻamau, e puhi ana i kēlā me kēia 240 ° (hoʻokahi huli / 2). I ka 70s / 80s Laverda i hoʻokuʻu i ka 180 ° ʻekolu-cylinder 1000, ʻoi aku ka nui o ka mīkini "ʻano" ma mua o nā mana i ukali ʻia 120 °. ʻO kēia kaʻa, i kapa ʻia ʻo "Jota" ma hope o kekahi ma ka Spanish three-stroke, he ʻokoʻa wale nō.

ʻO 4-stroke ʻekolu-cylinder ma GP

Ua 'oi aku ka maika'i o ka engine ekolu-cylinder i ka GP, mua ma 4 mau 'anu'u, i ke au hanohano MV Agusta, a laila ma 2 mau 'anu'u. He nani loa kona wā i hala a hiki i kēia lā ke lilo ka 800 F3 i ka MV3 350 (1965) a me 500 (1966) kaulana. 500 i kūkulu ʻia ma kahi o 80 hp. ma 12 rpm a ʻoi aku ma mua o 000 km / h. Ua lanakila ʻo ia ma ka liʻiliʻi he 270 mau poʻokela honua ma waena o 6 a me 1966 ma ka lima o Giacomo Agostini! Inā lawe nā mīkini virtual i kēia hoʻolālā fetish, loaʻa nā ʻenekini hou i kahi crankshaft counter-rotating e hōʻemi i ka hopena gyroscopic o ke kaʻa a hoʻonui i kona agility.

Ua ʻike hou mākou i ka GP ʻekolu-cylinder i ka wā o ka hoʻonui ʻana i ka ʻehā-stroke. I ka makahiki 2003, ua hoʻololi ʻia ʻo ia ma ke ʻano he Aprilia Cube, ʻoi aku ka liʻiliʻi o ka manaʻo ma mua o ka VM. ʻOiaʻiʻo, hoʻohui kēia mīkini i ka haiki pili a me ka hiki ke hoʻololi a no laila e hoʻomohala i nā mana kikoʻī nui. ʻO "Relatively" paha he ʻāpana o ka pilikia Cuba, no ka mea i kēia manawa pono ʻoe e hōʻea i nā wikiwiki loa e hoʻoikaika iā ʻoe iho i kāu GP.

ʻAʻole kūpono nā ʻano hana me ka hoʻokaʻawale ʻana i nā neʻe. Hoʻopaʻi kēia i nā wikiwiki laina o ka piston, e like me kā mākou e kūkākūkā ai ma hope. Me nā iwi ʻaoʻao 88,6 X 53,5 "i hoʻolaha ʻia", ua hakakā ka cube ma mua o 15 rpm. He haʻahaʻa loa ka ʻai, me ka laulā haiki. ʻO ka hopena he ʻenekini hana ʻino i keakea i ka paʻa a me ka maʻalahi o ke kaʻa.

Kaulike

ʻO ia ke kumu i loaʻa ai i ka māhele supersport, e like me ka SBK, ua loaʻa i nā cylinders ʻekolu kahi lanakila offset ma luna o nā cylinders 4. No laila ua ʻike mākou i ka hahau 675 cc o ka MV ʻekolu pahu a me ka Triumph versus ka 3 cc 600 cylinder. Ma SBK i ka manawa o 3 4-cylinder, 750 ʻekolu-cylinder a me 4 twin-cylinder. Ua ʻae kēia iā Petronas e hoʻohana i kahi 900 hoihoi me kahi ʻenekini hoʻohuli: hoʻohuli (ka pau ʻana ma hope, ke komo ʻana ma ke alo a me nā pahu pahu tilted i hope). ʻO kahi laʻana maikaʻi o "nā wāwae ʻekolu".

ʻO ke kānāwai no ka hoʻomanawanui he 600 ʻehā mau pahu, akā no ʻekolu mau pahu e pono e ʻoi aku ma mua o 750 cm3. ʻAʻole ʻike ʻia nā ʻokoʻa i ka GP, ʻoi aku i kēia lā, i ka wā i hoʻonohonoho ai nā lula i ka nui o 4 cylinders a me kahi pahu ʻaʻole ʻoi aku ma mua o 81mm. ʻO ka ʻoiaʻiʻo, ʻo nā ana o ka GP ʻekolu-cylinder, hiki ke hoʻololi ʻia i ka maikaʻi loa, ʻo ia ka 81 X 48,5 mm a i ʻole ka wikiwiki kiʻekiʻe ma kahi o 17 rpm ma kahi piston linear wikiwiki o 000 m / s. Ma waho aʻe o ka horsepower kiʻekiʻe, ʻoi aku ka maikaʻi, aia ka lole wikiwiki e makaʻala, ʻaʻole kūpono me ka helu o nā ʻenekini i ʻae ʻia i kēlā me kēia kau. No laila, ʻokoʻa ka ʻimi ʻana i nā pilikia, ʻaʻohe mea e hoʻolimalima i ka ʻekolu-cylinder a hiki i ka ʻike hou aku.

Liʻiliʻi akā ikaika

I ka wā e pili ana i ka heihei alanui a me nā haʻuki, hoʻowahāwahā ka triple i kēia mau pilikia. Hoʻokani ʻo ia me kona compactness (800 MW wale nō ke kaumaha o 52 kg!) No ka lawelawe ʻana i nā kaʻa kaʻa e hoʻohauʻoli mau loa i kāna hoʻokani ʻana, e hāʻawi iā ia i kahi pane throttle ʻoluʻolu a me kahi noho maoli. Hōʻike ʻia kēia e nā pihi mai ka manual engine kaulana. ʻO ka mua, ʻike mākou i ka torque hikiwawe o ka ʻenekini 1616cc (3 X 3cc) ʻekolu pahu.

Aia nā kiʻekiʻe ma 603 Nm, ʻoiai ma ka ʻaoʻao aʻe ka 4 cylinders 2155 (4 X 538 cm3), akā naʻe e hoʻomohala i kahi kiʻekiʻe awelika torque (180 Nm versus 135), he 425 Nm wale nō o ka torque kiʻekiʻe koke. !

ʻO ka pōkole, me ka liʻiliʻi o ka neʻe ʻana a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka kiʻekiʻe o nā kiʻekiʻe kiʻekiʻe o ʻekolu pahu ma mua o ka mīkini 4-cylinder, ʻo ia hoʻi ka hauʻoli o ka mea hoʻokele.

hopena

Inā he mauna alahele, alanui kaʻa a i ʻole mauna kaʻa haʻuki, he ʻenekini hoʻohiwahiwa ʻoi aku ka liʻiliʻi a ʻoi aku ka māmā ma mua o ka pahu ʻehā. ʻO nā hiʻohiʻona e hoʻohiki iā ia i ka wā e hiki mai ana ma nā huila ʻelua a ʻehā. ʻOiaʻiʻo, ke kau ʻia nei ma lalo o nā puʻupuʻu o nā kaʻa hou i nā mana me ka supercharging o 1000 a i ʻole 1200 cm3. ʻOiaʻiʻo, ʻaʻole i pau kāna kāhāhā iā mākou!
