Iimfuno zokuphumeza imigangatho engqongqo yokukhutshwa kwezithuthi kunye nokusetyenziswa kwepetroli kukhokelele kulo lonke ushishino lweenqwelo-mafutha ukuba lugxadazele ukuhlangabezana nolu phuculo.Ukuze kuncitshiswe ukusetyenziswa kwamafutha kunye nokukhutshwa kwe-exhaust, indlela eqhelekileyo ibikukunciphisa ubunzima bemoto.Ke ibhloko ye-aluminium alloy cylinder block endaweni yentsimbi etyhidiweyo iye yavela kwindlela yophuhliso.Ukongeza, ukusebenza kakuhle kokutsha kwe-injini kunokuphuculwa ngokumangalisayo ngokunciphisa ukukhuhlana ngaphakathi kwe-injini.Ke ngoko, itekhnoloji entsha ye-injini yemoto "ye-cylinder Liner less" itsale ingqalelo yabaninzi abavelisi beemoto.
Iinjini zeemoto (ii) cylinder liner ngaphantsi kwetekhnoloji yaphunyezwa ngokungeniswa kobuchwephesha bokutshiza nge-thermal.Ukusetyenziswa kokutshiza kwe-thermal kwenziwa ngexesha lenkqubo yokuvelisa i-injini ye-injini.Isitshizi sigalelwa kumphezulu wamabhore e-cylinder enjini ye-aluminiyam.Isitshizi songeza umaleko ongagugiyo wengxubevange enekhabhoni ephantsi ukuze ungene endaweni yesilinda yesilinda yentsimbi.Ukusetyenzwa kweebhloko ze-cylinder ezingenazo ii-liners kubandakanya oku kulandelayo kumacandelo eenkqubo kunye nezicelo:
● ukuphosa
● ukwenza rhabaxa ibhloko yesilinda
● texturing-roughing up the cylinder bore
● ukufudumeza umgangatho
● ukutshiza nge-thermal
● ukugqiba oomatshini
● ukugqiba ukucula
Iinkqubo eziphambili zetekhnoloji ye-cylinder encinci ye-liner zenziwa kwi-coaxial surfaces (ii-cylinders ezimbini ezine-cylindrical surfaces zibandakanya imigca edlula kwizangqa ezigxininisiweyo kwinqwelo-moya enikeziweyo kwaye i-perpendicular kule nqwelo-moya) ngokugqithisa umphezulu we-cylinder.Oku kuphunyezwa ngu:
Injongo yokwenziwa rhabaxa kumphezulu kuyafuneka ukunyusa umgangatho womhlaba ukwenza ubume bomphezulu obuvumela ukwambathisa ukuba udityaniswe ngoomatshini kumphezulu we-substrate, ukwandisa amandla okuluma ngoomatshini kwi-substrate kunye nokuvula ngakumbi kunye nokuphucula umphezulu. Amandla okubopha izinto eziphathekayo.Ukwenziwa rhabaxa phezu komhlaba kwenziwa ngeendlela ezahlukeneyo, njengokuqhushumba kwegrit, ukurhabaxa ngoomatshini, kunye noxinzelelo oluphezulu lwejethi yamanzi.Igrit blasting lolona nyango luxhaphakileyo lusetyenziswayo lokurhaxa kwaye lusebenza kuzo zonke iindawo ezirhabaxa.
Imiphezulu yentsimbi ingacocwa, irhabaxa kwaye isebenze kakhulu emva kokuqhunyiswa kwesanti.Lo mphezulu urhabaxa emva koko ucocwe ngomoya owomileyo ongenao-oyile ophezulu phambi kokufaka inkqubo yokutshiza.
Ukurhabaxa (Ukusebenza komphezulu) nako kunokwenziwa ngokusetyenziswa komatshini.Kwaye kukho iinkqubo apho umphezulu we-aluminiyam ubunjwe ube yicontour ethile.Oku kwenziwa ngokusetyenziswa kweziko lomatshini omnye-axis kunye nokusetyenziswa kwezixhobo zokusika ezifakiweyo.Le yinkqubo yexesha elinye ukugqibezela iimpawu ngendlela eneendleko.Kwimeko ye-cylinder yentsimbi endala erhawuzekileyo kakhulu, ukunxitywa kwesixhobo esigqithisileyo kunye nokukrazuka kuye kwadalwa rhoqo okwenza oku kungamkeleki kwezoqoqosho.
Uxinzelelo oluphezulu lwejethi yamanzi lusebenza kuphela kwi-cylinder ye-aluminium kwaye ayisebenzi kwi-cylinder yentsimbi.Inkqubo yejethi yamanzi ayisebenzisi iibrasives ezibizayo.Nangona kunjalo ukusetyenziswa ngokuthe ngqo kwejethi yolwelo kumphezulu we-substrate kwenziwa kuphela xa umphezulu womile.Kwaye nangona kunjalo ixabiso loburhabaxa bomphezulu lisezantsi xa lithelekiswa nezinye iinkqubo.
I-Surface roughening njengenkqubo ephambili kwitekhnoloji ye-non-cylinder ichaphazela ngokuthe ngqo amandla okudibanisa kunye neempawu zokugquma kwengubo.Ke ngoko, kubalulekile ukunikela ingqalelo kwinkqubo yokurhabula komhlaba ekusetyenzisweni kwetekhnoloji yebhloko yesilinda esincinci.Ukukhethwa kweyona ndlela ifanelekileyo yokurhaxa kubalulekile ekuphumezeni eyona ndlela ilungileyo yokusebenza komphezulu kunye nokusebenza kakuhle kwemveliso.
