A na-ekewa ihe mgbochi cylinder nke engine petrol ka ọ bụrụ ígwè nkedo na aluminom. Tụlee uru na ọghọm dị na aluminum cylinder na nkedo ígwè cylinder: 1) Ibu ibu

Nnukwu ike ndọda nke aluminom dị ntakịrị karịa nke nkedo ígwè, na ngọngọ cylinder aluminom dị ọkụ karị n'okpuru ebe obibi nke imezu ike chọrọ. Igwe ahụ dị ọkụ, nke na-enwe mmetụta dị mma na nkesa arọ nke ụgbọ ala, na ịdị arọ nke ụgbọ ala ahụ dịkwa ọkụ. Ya mere, n'oge a, aluminom cylinders na-achịkwa.

2) Olu

N'ihi otu ihe ahụ, ike ndọda kpọmkwem nke aluminom dị ntakịrị, na ike nhazi nke aluminum kwa otu olu dị obere karịa nke nkedo ígwè, ya mere, aluminom cylinders na-abụkarị ibu na olu. Ihe mgbochi cylinder nke EA113/EA888 nwere oghere etiti-na-cylinder nke 88mm, ebe ụdị dị adị nwere dayameta cylinder ruo 82.5mm. Ewezuga ọwa mmiri jụrụ oyi, mgbidi cylinder dị ezigbo mkpa. N'ụzọ dị otú a, dum engine bụ nnọọ kọmpat na obere na size. Aluminom cylinders siri ike karị iji nweta mmetụta a. N'oge a, ihe nkedo cylinder block na-achị. [Mgbakwunye: Ike ike nke ductile cast iron nwere ike karịa 1000MPa, ebe ike ike nke ụgbọ elu 7075 aluminum alloy bụ 524MPa, njupụta nke ígwè bụ 7.85, na njupụta nke aluminom bụ 2.7. Ya mere, iji nweta otu ike ahụ, ọ dị mkpa ka a na-amụba olu nke aluminum alloy site na otu. Oge, mana ịdị arọ dị ihe dịka 40% dị mfe.]

3) Nguzogide corrosion na ike

Aluminom dị mfe iji mmiri eme ihe n'ụzọ kemịkal na mmiri a na-emepụta n'oge combustion, na nguzogide corrosion ya adịghị mma dị ka nke nkedo ígwè cylinder blocks, karịsịa maka nnukwu engines nwere okpomọkụ na nrụgide dị elu. Na nkwubi okwu gara aga banyere ụda olu, n'aka nke ọzọ, mgbe ịchọrọ olu engine gị dị ntakịrị, ọ na-esikarị ike iji nweta ike nke nkedo ígwè cylinder block na aluminum cylinder block. Ya mere, ọtụtụ engines nwere nnukwu ụgwọ na-eji ihe nkedo ígwè, dị ka (tupu ọgbọ nke itoolu) EVO's 286hp 2.0L I4 (4G63), bụ nke a na-agbanye ígwè mgbe niile. Oke mgbanwe mgbanwe ya bụkwa nke amara nke ọma. Ọ bụrụ na ejiri cylinder aluminum mee ihe, ọ nwere ike ọ gaghị adị mfe. N'oge a, ihe nkedo cylinder block na-achị.

4) Ọnụ ego

Ọnụ ego a na-akwụ bụ na aluminom cylinder dị ọnụ karịa, ọ dịghịkwa ihe ọ bụla ịkọwa. N'oge a, ihe nkedo cylinder block na-achị.

5) Mgbochi mgbawa na ikpo ọkụ ọkụ

Aluminom na-eduzi okpomọkụ ngwa ngwa, n'ihi ya, ọ na-arụ ọrụ dị mma nke ọma, nke nwere ike inyere engine aka belata ohere nke combustion na-adịghị mma. N'otu aka ahụ mkpakọ, engines aluminom cylinders nwere ike iji mmanụ ụgbọala dị ala karịa nke nkedo ígwè cylinder engine. N'oge a, aluminom cylinder block na-achị.

6) ọnụ ọgụgụ esemokwu

Iji belata inertia nke akụkụ ndị na-emegharị ahụ ma mee ka ọsọ ọsọ na-agba ọsọ na ọsọ nzaghachi, ọtụtụ n'ime pistons na-eji aluminum alloy dị ka ihe. Ọ bụrụ na a na-ejikwa aluminom mee mgbidi cylinder ahụ, ọnụọgụ nke esemokwu n'etiti aluminom na aluminom dị oke ibu, nke na-emetụta ọrụ nke engine. Igwe nkedo enweghị nsogbu dị otú ahụ. N'ebe a, ihe nkedo cylinder blocks na-achịkwa. [Mgbakwunye: ụfọdụ ihe a na-akpọ "all-aluminum" engines na-ejikwa nkedo cylinder liners. na ngwụcha:

Uru nke aluminom: ịdị arọ dị arọ, ikpo ọkụ dị mma;
Uru nke ígwè: ọnụ ala na inogide.
