I-cylinder block yenjini kaphethiloli ihlukaniswe ngensimbi eyinsimbi ne-cast aluminium. Qhathanisa okuhle nokubi kwesilinda se-aluminium nesilinda sensimbi: 1) Isisindo

Amandla adonsela phansi e-aluminium mancane kunalawo ensimbi ekhonjiwe, futhi ibhulokhi yesilinda ye-aluminium ilula kakhulu ngaphansi kwesisekelo sokuhlangabezana nezidingo zamandla. Injini ilula, okunomthelela omuhle ekusabalaliseni isisindo semoto, kanti nesisindo semoto sibuye sibe lula. Ngakho-ke, kuleli phuzu, amasilinda e-aluminium abusa.

2) Ivolumu

Ngesizathu esifanayo, amandla adonsela phansi e-aluminium mancane, futhi amandla esakhiwo se-aluminium ngeyunithi ngayinye angaphansi kwalawo ensimbi ekhonjiwe, ngakho-ke amasilinda e-aluminium avame ukuba mkhulu ngevolumu. Ibhulokhi yesilinda ye-EA113/EA888 inebanga eliphakathi nendawo ukuya kusilinda elingu-88mm, kuyilapho inguqulo ekhona inobubanzi besilinda obufika ku-82.5mm. Ngaphandle komzila wamanzi okupholisa, udonga lwesilinda empeleni luncane kakhulu. Ngale ndlela, yonke injini ihlangene kakhulu futhi incane ngosayizi. Amasilinda e-aluminium anzima kakhulu ukufeza lo mphumela. Kuleli qophelo, i-cast iron cylinder block iyinhloko. [Isengezo: Amandla aqinile we-ductile cast iron angaba ngaphezu kuka-1000MPa, kuyilapho amandla aqinile e-aviation 7075 aluminium alloy engu-524MPa, ukuminyana kwensimbi ngu-7.85, kanti ukuminyana kwe-aluminium kungu-2.7. Ngakho-ke, ukuze uthole amandla afanayo, umthamo we-aluminium alloy udinga ukukhushulwa cishe ngomunye. Izikhathi, kepha isisindo singaba ngu-40% elula]

3) Ukumelana nokugqwala namandla

I-Aluminium kulula ukusabela ngayo ngokwekhemikhali ngamanzi akhiqizwa ngesikhathi sokusha, futhi ukumelana nokugqwala kwayo akufani nokwamabhulokhi esilinda ensimbi, ikakhulukazi ezinjinini ezishajwe kakhulu ezinokushisa okuphezulu nokucindezela. Futhi isiphetho sangaphambilini mayelana nevolumu, ngakolunye uhlangothi, lapho izidingo zevolumu yenjini yakho zincane uma kuqhathaniswa, ngokuvamile kunzima ukufeza amandla e-cast iron cylinder block nge-aluminium cylinder block. Ngakho-ke, izinjini eziningi ezine-supercharge ephezulu zisebenzisa amabhulokhi ensimbi acijile, njengokuthi (ngaphambi kwesizukulwane sesi-9) i-EVO's 286hp 2.0L I4 (4G63), ehlala ingamabhulokhi ensimbi. Umkhawulo wayo ophezulu wokuguqulwa nawo waziwa kakhulu. Uma kusetshenziswa isilinda se-aluminium, kungase kungabi lula. Kuleli qophelo, i-cast iron cylinder block iyinhloko.

4) Izindleko

Izindleko ngokwemvelo ukuthi isilinda se-aluminium sibiza kakhulu, futhi akukho lutho oluchazayo. Kuleli qophelo, i-cast iron cylinder block iyinhloko.

I-5) Ukumelana nokuqhuma nokukhishwa kokushisa

I-Aluminium ihambisa ukushisa ngokushesha, ngakho inokusebenza okuhle kokupholisa, okungasiza injini yehlise amathuba okuvutha okungavamile. Ngesilinganiso esifanayo sokucindezela, izinjini ze-aluminium cylinder zingasebenzisa uphethiloli wezinga eliphansi kunezinjini zamasilinda ensimbi. Kuleli qophelo, i-aluminium cylinder block iyinhloko.

6) I-friction coefficient

Ukuze kuncishiswe i-inertia yezingxenye eziphindaphindayo futhi kwandiswe isivinini sokujikeleza kanye nesivinini sokuphendula, iningi lama-pistons lisebenzisa i-aluminium alloy njengento. Uma udonga lwe-cylinder lwenziwe nge-aluminium, i-coefficient of friction phakathi kwe-aluminium ne-aluminium inkulu kakhulu, okuthinta kakhulu ukusebenza kwenjini. I-cast iron ayinayo inkinga enjalo. Kuleli qophelo, i-cast iron cylinder block iyabusa. [Isengezo: ezinye izinjini ezibizwa nge- "all-aluminium" nazo zisebenzisa i-cast iron cylinder liners] Ekuphetheni:

Izinzuzo ze-aluminium: isisindo esilula, ukuchithwa kahle kokushisa;
Izinzuzo zensimbi: ezishibhile futhi zihlala isikhathi eside.
