Iyo cylinder block yepeturu injini yakakamurwa kuita simbi yakakandwa uye yakakandwa aluminium. Enzanisa zvakanakira uye kuipa kwealuminium cylinder uye cast iron silinda:
1) Kurema
Iyo chaiyo giravhiti yealuminium idiki pane iyo yesimbi yakakandwa, uye aluminium cylinder block yakareruka zvakanyanya pasi pechikonzero chekusangana nezvinodiwa zvesimba. Injini yakareruka, iyo ine simba rakanaka pakuparadzirwa kwehuremu hwemotokari, uye uremu hwemotokari zvakare zvakareruka. Naizvozvo, panguva ino, masimbi ealuminium anotonga.
2) Inzwi
Nechikonzero chimwe chete, iyo chaiyo giravhiti yearuminiyamu idiki, uye kuumbwa kwesimba realuminium pavhoriyamu yevhoriyamu ishoma pane yesimbi yakakandwa, saka masilinda ealuminium anowanzo kukura muhuwandu. EA113/EA888's cylinder block ine pakati-ku-cylinder chinhambwe che88mm, nepo shanduro iripo ine silinda dhayamita kusvika 82.5mm. Kunze kwemugero wemvura inotonhorera, madziro ecylinder akanyanya kutetepa. Neiyi nzira, iyo injini yese yakanyanya compact uye idiki muhukuru. Aluminium cylinders yakanyanya kuoma kuita izvi. Panguva ino, iyo cast iron cylinder block ndiyo inotonga. [Kuwedzera: Kusimba kwesimba re ductile cast iron inogona kudarika 1000MPa, ukuwo simba rekusimba rendege 7075 aruminiyamu alloy i524MPa, density yesimbi i7.85, uye density yealuminium i2.7. Naizvozvo, kuti uwane simba rakafanana, huwandu hwealuminium alloy hunoda kuwedzerwa neinenge imwe. Nguva, asi huremu hunenge 40% kureruka]
3) Corrosion kuramba uye simba
Aluminium iri nyore kuita kemikari nemvura inogadzirwa panguva yekupisa, uye kudzivirira kwayo kwekuora hakuna kunaka seye cast iron cylinder blocks, kunyanya kumajini ane supercharged ane tembiricha yepamusoro uye kudzvanywa. Uye mhedziso yapfuura nezve vhoriyamu, kune rumwe rutivi, kana injini yako inoda vhoriyamu iri diki, kazhinji zvakaoma kuwana simba reiyo cast iron cylinder block nealuminium cylinder block. Nokudaro, injini dzakawanda dzepamusoro-soro dzinoshandisa zvidhinha zvesimbi, zvakadai se (pamberi pechizvarwa chechi9) EVO's 286hp 2.0L I4 (4G63), iyo inogara yakakanda simbi. Muganho wayo wepamusoro wekugadzirisa unozivikanwa zvakare. Kana aluminium cylinder ikashandiswa, zvingasava nyore. Panguva ino, iyo cast iron cylinder block ndiyo inotonga.
4) Mutengo
Mutengo wacho ndewekuti aluminium cylinder inodhura zvakanyanya, uye hapana chekutsanangura. Panguva ino, iyo cast iron cylinder block ndiyo inotonga.
5) Kurwisana nekuputika uye kupisa kupisa
Aluminium inoitisa kupisa nekukurumidza, saka ine yakanaka kutonhora kuita, iyo inogona kubatsira injini kuderedza mukana wekupisa kusingaite. Panguva imwechete yekumanikidza reshiyo, injini dzealuminium cylinder dzinogona kushandisa peturu yegiredhi yakaderera pane inokandwa simbi silinda injini. Panguva ino, iyo aluminium cylinder block ndiyo inotonga.
6) Friction coefficient
Kuti uderedze inertia yezvikamu zvinodzokorora uye kuwedzera kukurumidza kutenderera uye kumhanya kwekupindura, mazhinji emapistoni anoshandisa aluminium alloy sechinhu. Kana iyo cylinder wall yakagadzirwawo nealuminium, iyo coefficient of friction pakati pealuminium nealuminium yakakura, iyo inokanganisa zvikuru kushanda kwejini. Simbi yakakandwa haina dambudziko rakadaro. Panguva ino, simbi yakakandwa cylinder blocks inotonga. [Kuwedzera: mamwe anonzi "all-aluminium" injini dzinoshandisawo cast iron silinda liners]
mukupedzisa:
Zvakanakira zvealuminium: uremu huremu, kunaka kwekupisa kupisa;
Zvakanakira simbi: yakachipa uye yakasimba.
