Njengenhliziyo yemoto, injini ithinta ngqo ukusebenza kukonke kwemoto.Njengamanje, ngokuthuthukiswa kwemoto ekubhekeni kwe-lightweight, ingxenye yokusetshenziswa kwenjini ye-aluminium embonini yezimoto iphezulu futhi iphakeme.Ngenxa yokuthi ukumelana nokugqokwa kwe-aluminium alloy akukuhle njengensimbi ekhonjiwe, i-cast iron cylinder liner kufanele ishunyekwe enjinini ye-aluminium yendabuko ukuze kuthuthukiswe ukumelana nokuguga.Kodwa-ke, okubi kwe-cast iron cylinder liner ukupakishwa phakathi kwe-cylinder liner kanye ne-cylinder block.Ngenxa yezici ezihlukene zomthamo wokushisa wezinto ezimbili, kuzothinta ukuqina kwebhulokhi yesilinda senjini ye-aluminium.Mayelana nalokhu, abakhiqizi bezimoto zakwamanye amazwe baye bahlakulela ubuchwepheshe obusha benqubo, okungukuthi ubuchwepheshe be-cylinder hole spraying, obungabizwa nangokuthi ubuchwepheshe bamahhala be-cylinder liner.
Ubuchwepheshe bokufafaza nge-cylinder bore bubhekisela ekusetshenzisweni kobuchwepheshe bokufafaza okushisayo (ukufafaza nge-arc noma ukufutha nge-plasma) ukufafaza ungqimba lwe-alloy coating noma ezinye izinto eziyinhlanganisela odongeni olungaphakathi lwebhore yenjini ye-aluminiyamu eqinile ukuze kungene esikhundleni somugqa wesilinda wensimbi eyisilinda.Ibhulokhi yesilinda ehlanganisiwe ye-aluminium ehlanganisiwe iseyibhulokhi yesilinda ehlanganisiwe, futhi ugqinsi lwe-coating luyi-0.3mm kuphela.Inezinzuzo zokunciphisa isisindo senjini, ukunciphisa ukungqubuzana nokuguga phakathi kwembobo yesilinda ne-piston, ukuthuthukisa ukuqhutshwa kokushisa, ukunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa kwe-CO2.
Njengamanje, lobu buchwepheshe obusha busetshenziswe enjinini ye-ea211 yakwaVolkswagen, injini kagesi ye-Audi A8 kaphethiloli, VW Lupo 1.4L TSI, GM Opel, Nissan GT-R injini, injini yakamuva ye-BMW B-series, injini engu-5.2L V8 ( voodoo) kuFord Mustang shelbygt350 entsha, injini engu-3.0T V6 (vr30dett) ku-Nissan Infiniti Q50 entsha, njll. E-China, abanye abakhiqizi bezimoto nabakhi bezinjini nabo sebeqalile ukuhlola lobu buchwepheshe obusha.Kukholakala ukuthi ziningi izinjini ezizosebenzisa lobu buchwepheshe obusezingeni eliphezulu esikhathini esizayo.
