Parizvino, kune marudzi maviri makuru einjini dzemotokari: injini dzesimbi dzakakandwa uye ese-aruminiyamu injini. Saka ndeipi yeiyi injini yemidziyo ndiyo yakanakisa kushandisa? Ndeupi musiyano pakati peinjini mbiri? Muchokwadi, dzinenge dzese injini humburumbira musoro zvinhu zvinogadzirwa nealuminium, nekuti aruminiyamu silinda misoro ine yakanakisa kupisa kupisa kuita. Musoro wecylinder weinjini yesimbi yakakandwa ichokwadi aruminiyamu alloy, asi cylinder block isimbi yakakandwa.
Kana ichienzaniswa neye-aluminum injini, cylinder block yeinjini yekukanda-iron ine simba rinopisa rinopisa, iro rinowedzera kuwedzera simba rejini. Semuenzaniso, pasi pekuita kwe turbocharging, 1.5L displacement cast-iron injini inogona chaizvo kusvika kune 2.0L yekubvisa simba rinodiwa; nepo injini yearuminiyamu yese haigone kuita zvinodiwa zvakadaro. Parizvino, motokari shoma dzepamusoro-soro dzinoshandisa injini yose yealuminium.
Pamusoro pezvo, ese-aruminiyamu injini dzinowanzoita makemikari kuita nemvura panguva yebasa, uye kushora kwavo kudiki kudiki pane iyo yesimbi yakakandwa masilinda, uye kusimba kwemasilinda ealuminium akadzikira zvakanyanya kupfuura aya emasilinda esimbi. Naizvozvo, chaizvo ese ma turbocharged engines anokandwa esimbi zvidhinha. Zvakakodzera kutaura kuti iyo cast iron cylinder block inewo simba rekugadzirisa iro aluminium muviri injini haina.
Kusiyana neizvi, mukana mukuru weinjini dzese-aruminiyamu nderekuti panguva imwe chete yekutamiswa, huremu hwearuminiyamu ese-aruminiyamu injini dzinenge 20kg dzakareruka pane dzeinjini dzesimbi dzakakandwa. Mukuwedzera, kupisa kwekushisa kwejini-aruminiyamu injini iri nani zvikuru kupfuura yejini yakakandwa-simbi, iyo inogona kuvandudza kushanda kweinjini uye kubatsira kuwedzera hupenyu hwebasa rejini.
Parizvino, anenge ese ejini pistons akagadzirwa nealuminium alloy. Kana iyo cylinder wall material iriwo ese aruminiyamu, iyo coefficient yekupokana pakati pealuminium nealuminium yakakura kwazvo, izvo zvinokanganisa kushanda kweinjini. Ichi ndicho chikonzero simbi dzakakandwa dzesimbi dzinogara dzakaiswa muhumburumbira muviri weese-aluminium injini.
Muchokwadi, muchidimbu, iyo yese-aluminium injini ine hunhu hwekugadzirisa nyore, huremu huremu, uye kunaka kwekupisa kupisa. Mabhenefiti einjini dzesimbi dzakakandwa anoratidzwa mukupikiswa kwakanyanya, kupisa kwakanyanya kwekushisa, corrosion resistance, deformation resistance uye mutengo wakaderera.
