Zvakanakira zvealuminium:

Parizvino, cylinder blocks ye peturu injini akakamurwa kuita simbi yakakandwa uye akakanda aluminium. Muinjini dzedhiziri, simbi yakakandwa cylinder blocks ndiyo yakawanda. Mumakore achangopfuura, nekukurumidza kukura kweindasitiri yemotokari, mota dzakakurumidza kupinda muhupenyu hwevanhuwo zvavo, uye panguva imwecheteyo, kuchengetedza mafuta kwemotokari kwave kutariswa zvishoma nezvishoma. Deredza huremu hweinjini uye chengetedza mafuta. Kushandiswa kweakakandirwa aluminium cylinder kunogona kuderedza huremu hweinjini. Kubva pakuona kwekushandiswa, mukana wekukanda aluminium cylinder block uremu huremu, hunogona kuchengetedza mafuta nekuderedza uremu. Muinjini yekutamiswa kwakafanana, kushandiswa kweinjini yealuminium-cylinder kunogona kuderedza huremu hwemakirogiramu makumi maviri. Kune yega yega kuderedzwa kwegumi muzana muhuremu hwemotokari pachayo, kushandiswa kwemafuta kunogona kudzikiswa ne6% kusvika 8%. Zvinoenderana neazvino data, huremu hwemotokari dzekunze hwakadzikiswa ne20% kusvika 26% zvichienzaniswa nekare. Semuenzaniso, Focus inoshandisa iyo yose-aluminium alloy material, iyo inoderedza uremu hwemotokari yemotokari, uye panguva imwechete inosimudzira kupisa kwekupisa kwejini, inovandudza kushanda kweinjini, uye ine hupenyu hurefu. Kubva pamaonero ekuchengetedza mafuta, zvakanakira mainjini ealuminium yakakandwa mukuchengetedza mafuta zvakwezva pfungwa dzevanhu. Pamusoro pemusiyano wehuremu, kune zvakare misiyano mizhinji pakati peakakanda simbi silinda zvidhinha uye akakanda aruminiyamu silinda zvidhinha mukugadzira maitiro. Iyo yekukanda simbi yekugadzira mutsara inotora nzvimbo yakakura, ine yakakura kusvibiswa kwezvakatipoteredza, uye ine yakaoma kugadzirisa tekinoroji; nepo maitiro ekugadzira eakakanda aluminium cylinder blocks ari kungopesana. Kubva pamaonero emakwikwi emusika, akakanda aluminium cylinder blocks ane zvimwe zvakanakira.

Zvakanakira iron:

Zvinhu zvemuviri zvesimbi nealuminium zvakasiyana. Iyo yekupisa inotakura huwandu hweiyo cast iron cylinder block yakasimba, uye kugona kwesimbi yakakandwa yakakura maererano nesimba reinjini parita. Semuenzaniso, simba rekubuda re 1.3-litre cast iron engine rinogona kudarika 70kW, nepo simba rekubuda reinjini yealuminium yakakandwa inogona kusvika 60kW. Zvinonzwisiswa kuti 1.5-litre displacement cast iron injini inogona kusangana nezvinodiwa zvesimba zve 2.0-litre displacement injini kuburikidza ne turbocharging uye mamwe matekinoroji, nepo iyo yakakandwa aruminiyamu humburumbira injini yakaoma kuzadzisa ichi chinodiwa. Naizvozvo, vanhu vazhinji vanogona zvakare kuputika zvinoshamisa torque kubuda kana uchityaira Fox nekumhanya kwakaderera, izvo zvisingaite chete kutanga uye kukurumidza kwemotokari, asi zvakare inogonesa kuchinjika kwekutanga kwegiya kuti uwane mhedzisiro yekuchengetedza mafuta.　　Aluminium cylinder block ichiri kushandisa simbi yakakandwa kune chikamu cheinjini, kunyanya silinda, inoshandisa simbi yakakandwa. Iyo yekupisa yekuwedzera kweyero yeakakandirwa aluminium uye simbi yakakandwa haisi yunifomu mushure mekunge mafuta apiswa, rinova dambudziko re deformation consistency, iro dambudziko rakaoma mukukanda maitiro ekukanda aluminium cylinder blocks. Kana injini iri kushanda, iyo yakakandwa aluminium silinda injini yakashongedzerwa nesimbi yakakandwa masilinda inofanirwa kusangana nezvinodiwa zvekuisa chisimbiso. Nzira yekugadzirisa dambudziko iri idambudziko rinokanda aluminium cylinder block makambani anobhadhara zvakanyanya.
