Gịnị ma ọ bụrụ na ọ bụ ọgba tum tum ENGINE kacha mma?

N'oge gara aga anyị mara 3-cylinder 2-stroke, online na Kawasaki, Suzuki na Motobécane ma ọ bụ V-ejima na Honda. N'ezie, maka Honda, ndị a bụ linear engines nke cylinders e staggered iji nweta obosara. Enwere naanị otu mkpanaka njikọ maka manetton, na cylinder nke ọ bụla nwere ụlọ mgbapụta nwere onwe ya. Ejiri igwe ndị a nwere SRP ụzọ 400 yana 500 RS na NS GP. Nkọwa na-atọ ọchị, a tụgharịrị na okirikiri nhọrọ ukwuu: cylinders 2 kwụ ọtọ na nke kwụ ọtọ n'okporo ụzọ, na-abụghị nke GP. Eleghị anya na okwu ndị metụtara ngafe ite ntụrụndụ na okpomọkụ a tọhapụrụ ...

Na nkenke, ụbọchị ndị a, engines cylinder atọ bụ engines nwere ifufe na ụgbọ mmiri ha, ma ha niile nwere otu ụkpụrụ ụlọ: engine inline na n'ezie okirikiri 4-strok, n'ihi na strok abụọ anaghịzi enwe ifufe. n'ọnụ ụzọ ya…

Otu maka mmadụ niile, niile n'ịntanetị!

Maka nhazi kacha mma n'ihe gbasara ịma jijiji na oge cyclic, a na-edobe crankcase ọ bụla 120º iji hụ na arụ ọrụ mgbe niile, yana combustion ọ bụla 240º (otu ntụgharị/2). Na 70s/80s, Laverda pụtara na 180º atọ-cylinder 1000, nke nwere ọtụtụ ihe "njirimara" engine karịa nsụgharị ndị sochiri 120 °. Igwe a, aha ya bụ "Jota" n'otu n'otu na Spanish maka ọrịa strok atọ, ka dị iche.

4-strok atọ-cylinder na GP

Igwe silinda atọ ahụ mekwara nke ọma na GP, nke mbụ n'ime nzọụkwụ 4, n'oge MV Agusta dị ebube, wee na nzọụkwụ abụọ. Oge gara aga dị ebube nke na ọbụna taa a na-akpọ 2 F800 dịka "MV3" 3 (350) na 1965 (500). 1966 mepụtara gburugburu 500 hp. na 80 rpm ma gafere 12 km / h. O meriri ihe na-erughị 000 aha ụwa n'etiti 270 na 6 n'aka Giacomo Agostini! Ọ bụrụ na igwe mebere igwe na-eweghara ihe owuwu a, injin nke ọgbara ọhụrụ nwere crankshaft na-agbanwe agbanwe nke na-ebelata mmetụta gyroscopic igwe kwụ otu ebe ma na-enyere aka ike ya.

N'oge na-adịbeghị anya, anyị hụrụ GP-cylinder atọ ọzọ n'oge mgbanwe gaa na ọrịa strok anọ. Otú ọ dị, na 2003, n'okpuru uwe nke Aprilia Cube, ọ bụchaghị nkwenye karịa VM. N'ezie, usoro a na-ejikọta ikwu narrowness na ike ime mgbanwe na ya mere ịzụlite dịtụ nnukwu kpọmkwem ike.

Ọ bụ n'ihi nke a na n'ụdị egwuregwu supersport, dị ka na SBK, cylinders atọ enwetala uru nkwụghachi karịa 4-cylinder. Ya mere, anyị hụrụ strok 675cc nke atọ cylinders MV na Triumph megide 3cc cylinders nke 600 cylinders. Na SBK n'oge 3 4-cylinder, 750 atọ-cylinder na 4 abụọ-cylinder. Nke a kwere ka Petronas na-agba ọsọ 900 na-adọrọ mmasị na engine gbadoro anya: ntụgharị (ngwunye n'azụ, ntinye n'ihu na cylinders gbatịrị azụ). Ezigbo ihe atụ nke "ụkwụ atọ".

Iwu ntachi obi na-ewe 600 cylinders anọ, mana cylinders atọ ga-agafe 750 cm3. Ọdịiche ndị na-adịghị na GP, karịsịa taa mgbe iwu setịpụrụ kacha nke 4 cylinders na ntanye nke ọ dịghị ihe karịrị 81mm. N'ezie, akụkụ nke GP-cylinder atọ, nke kachasị mma na ngbanwe, ga-abụ 81 X 48,5 mm ma ọ bụ oke ọsọ nke ihe dịka 17 rpm na ọsọ piston linear nke 000 m / s. Na mgbakwunye na ike kachasị, ma eleghị anya ntakịrị ihe ngosi, ngwa ngwa ngwa ngwa, na-ekwekọghị na ọnụ ọgụgụ nke engines kwere maka oge, ka a ga-atụ egwu. Yabụ, ewezuga ịchọta ihe isi ike, ọ nweghị onye ga-ewe injin silinda atọ ruo mgbe amara ọzọ.

Banyere okporo ụzọ na egwuregwu, okpukpu atọ na-eleghara okwu ndị a anya. Ọ na-egwuri egwu na compactness ya (800 MW na-atụ naanị 52 n'arọ!) Iji jee ọgba tum tum na-akpali akpali mgbe niile, ekele maka nhazi ya, nke na-enye ya ezigbo nzaghachi trotul na ezigbo "ọnụnọ". A na-egosipụta nke a site n'ọkpụkpụ si na ntuziaka injin a ma ama. Nke mbụ, anyị na-ahụ ike ozugbo nke injin cylinder atọ dị 1616cc (3 X 3cc).

E nwere ọnụ ọgụgụ kasị elu na 603 Nm, mgbe na-esote usoro 4 cylinders 2155 (4 X 538 cm3), nke ka o sina dị elu nkezi torque (180 Nm vs 135), nwere nanị 425 Nm nke ozugbo kacha torque !

Na nkenke, na obere mgbagharị na obere mgbawa nke dị ala, ọnụ ọgụgụ dị elu ozugbo nke cylinder atọ dị elu karịa nke injin 4-cylinder, nke pụtara ahụmahụ karịa maka onye na-anya ụgbọelu.
