Njengabaninzi benu, xa ndandisengumntwana ndandivuthela imali eninzi kwiimagazini zemoto kunakwizincamathelisi (ndandingumntu oncamathelayo ngokwam…). Kwakungekho intanethi kwaye ke, i-Autohoje, iTurbo kunye neCo. zakhangelwa ngokupheleleyo kangangeentsuku.
Ngolwazi oluncinci olukhoyo ngelo xesha (enkosi kwi-intanethi!) ukufunda kudla ngokunwenwela kwiinkcukacha zephepha lobugcisa. Kwaye nanini na xa ndibona i-injini yokufuduka, kwakukho umbuzo owafika kum: "kutheni isihogo sokufuduka kwe-injini kungekhona inani elijikelezayo?"
Ewe Ndiyazi. Amanqanaba am "e-nerdism" njengomntwana ayephezulu kakhulu. Nditsho ngebhongo elithile, ndiyavuma.
Ngethamsanqa, ukuba kuphela komntwana kwibala lokudlala elineemagazini zemoto kundenze ndaduma ngokumangalisayo phakathi kwabafundi abakhulu bebanga lesi-4 – kumntu owayengakwazi ukukhaba ibhola, ndikholelwe, ndandidume kakhulu kwibala lokudlala. Kwaye loo nto yandisindisa iziqephu ezininzi zokubethwa – ngoku sele ibizwa ngokuba bubundlavini, andithi? Phambili...
Kukho inkcazo yayo yonke into. Nangenxa yokuba ukufuduswa okusebenzayo kweenjini akulona inani elichanekileyo. Umzekelo, injini ye-2.0 l ayikho ncam i-2000 cm³, ino-1996 cm³ okanye 1999 cm³. Ngendlela efanayo ukuba injini ye-1.6 l ayinayo i-1600 cm³, kodwa i-1593 cm³ okanye i-1620 cm³.
Bhalisa kwincwadana yethu
Makhe siye kwingcaciso?
Njengoko usazi, ukufuduswa kubonisa isixa somthamo wangaphakathi wazo zonke iisilinda ze-injini. Sifumana eli xabiso ngokuphindaphinda indawo yomphezulu we-cylinder nge-stroke epheleleyo yepiston. Emva kokubala eli xabiso, phinda-phinda eli xabiso ngenani lilonke leesilinda.
Ukubuyela esikolweni (kwakhona…), ngokuqinisekileyo uyakhumbula ukuba ifomula yokufumana indawo yesangqa isebenzisa ixabiso le-Pi (Π) - into engaguqukiyo yemathematika enike uluntu into eninzi yokwenza kwaye endingayi kuyenza. thetha ngayo kuba iWikipedia sele indenzele yona.
Ukongeza kolu balo kusetyenziswa inani elingenangqiqo, ubunjineli bomatshini busebenza kunye nemilinganiselo ye-millimeter kuyilo lweendawo ezahlukeneyo ze-injini. Ke ngoko, amaxabiso abalwayo akafane abe ngamanani angqukuva.
Makhe siye kwimeko ephathekayo? Kulo mzekelo siza kusebenzisa i-1.6 l ezine-cylinder injini ene-piston stroke yi-79.5 mm kunye ne-cylinder diameter yi-80.5 mm. Inxaki iya kujongeka ngolu hlobo:
Ukufuduswa = 4 x (40.25² x 3.1416 x 79.5) | Isiphumo : 1 618 489 mm³ | Uguqulo kwi-cm³ = 1,618 cm³
Njengoko ubonile, kunzima ukuza nenani elingqukuva. "Yethu" i-1.6 litre injini yi-1618 cm³ emva kwayo yonke into. Kwaye ngezinto ezininzi ezixhalabisa iinjineli kuphuhliso lwe-injini, ukubetha inani elijikelezayo ekugxothweni akuyonye yazo.
Yiyo loo nto ukufuduswa kwe-injini kungazange kube inani elichanekileyo (ngaphandle kwamathuba). Yiyo loo nto ndingazange ndithande izibalo...
