Kimwe na benshi muri mwe, nkiri umwana nateraga amafaranga menshi kubinyamakuru by'imodoka kuruta kuri stikeri (Nanjye ubwanjye nari inkoni…). Nta enterineti yariho rero, Autohoje, Turbo na Co zashakishijwe cyane muminsi irangiye.
Hamwe namakuru make cyane aboneka muricyo gihe (urakoze kuri enterineti!) Gusoma akenshi bigera kubisobanuro byurupapuro rwa tekiniki. Kandi igihe cyose nabonaga moteri yimurwa, hari ikibazo cyangezeho: "kuki ikuzimu ari kwimura moteri atari numero izengurutse?"
Yego ndabizi. Urwego rwanjye rwa "nerdism" nkumwana rwari hejuru cyane. Ibi ndabivuze nishimye, ndatuye.
Ku bw'amahirwe, kuba umwana wenyine ku kibuga gikinirwaho hamwe n'ibinyamakuru by'imodoka byatumye mbona icyamamare mu banyeshuri bakomeye bo mu kiciro cya 4 - ku muntu utazi gutera umupira, munyizere, nari nkunzwe cyane ku kibuga. Kandi ibyo byankijije ibice byinshi byo gukubita - ubu byitwa gutotezwa, sibyo? Imbere…
Hano haribisobanuro kuri buri kintu. Ndetse kuberako kwimura neza moteri atari umubare nyawo. Kurugero, moteri ya 2.0 l ntabwo ari cm 2000 neza, ifite cm 1996 cyangwa cm 1999. Kimwe nuko moteri ya 1,6 l idafite cm 1600, ariko cm 1593 cyangwa cm 1620.
Iyandikishe mu kanyamakuru kacu
Reka tujye kubisobanuro?
Nkuko mubizi, kwimura byerekana igiteranyo cyimbere yimbere ya silinderi zose. Twabonye agaciro mugwiza ubuso bwa silinderi hamwe na piston yose. Nyuma yo kubara agaciro, gwiza gusa agaciro numubare rusange wa silinderi.
Tugarutse ku ishuri (nanone…), uribuka rwose ko formulaire yo kubona agace k'uruziga ikoresha agaciro ka Pi (Π) - imibare ihoraho yahaye ikiremwamuntu byinshi byo gukora kandi sinzabikora vuga kuberako Wikipedia yamaze kunkorera.
Usibye iyi mibare ukoresheje nimero idafite ishingiro, imashini yubukorikori ikorana na milimetero mugushushanya ibice bitandukanye bya moteri. Kubwibyo, kubara agaciro ni gake cyane.
Reka tujye murubanza rufatika? Kururugero tugiye gukoresha moteri ya 1,6 l enye ya moteri ifite piston ya piston ni 79.5 mm na diameter ya 80.5 mm. Ikigereranyo cyasa nkiki:
Gusimburwa = 4 x (40.25² x 3.1416 x 79.5) | Igisubizo : 1 618 489 mm³ | Guhindura cm³ = 1,618 cm³
Nkuko wabibonye, biragoye kuzana numubare uzengurutse. Moteri ya litiro 1,6 ni cm 1618 nyuma ya byose. Kandi hamwe nibibazo byinshi abajenjeri bafite mugutezimbere moteri, gukubita uruziga mukuzimura ntabwo arimwe muribi.
Niyo mpamvu kwimura moteri atari numubare nyawo (usibye kubwamahirwe). Kandi niyo mpamvu ntigeze nkunda imibare…
