Mufananidzo: Maonero maviri eiyo isina mafuta turbocharger yakagadzirwa neNASA.Mufananidzo nerubatsiro rweNASA Glenn Research Center (NASA-GRC).
Wakamboona mota dzichibhururuka dzichipfuura nepauri nehutsi hwesooty uchiyerera kubva mupipe yavo?Zviri pachena kuti utsi hwemhepo hunokonzera kusvibiswa kwemhepo, asi hazvisi pachena kuti vari kutambisa simba panguva imwe chete.Exhaust musanganiswa wemagasi anopisa anopomba achibuda nekukurumidza uye simba rose rinenge ririmo—kupisa uye kufamba (kinetic energy)—iri kupera zvisina basa mumhepo.Kwaisazova kutsvinda here kudai injini yaigona kushandisa simba rinorasa iroro neimwe nzira kuita kuti motokari imhanye nokukurumidza?Ndizvo chaizvo zvinoita turbocharger.
Injini dzemotokari dzinoita simba nekupisa mafuta mumagaba esimbi akasimba anonzi macylinders.Mhepo inopinda mucylinder yega yega, wosangana nefuturu, wotsva kuita kakuputika kanoburitsa pisitoni, uchitenderedza mashafts nemagiya anotenderera mavhiri emota.Kana piston yadzokera mukati, inopomba mweya wemarara uye mafuta musanganiswa kubva muhumburumbira semhepo.Kuwanda kwesimba rinogadzirwa nemotokari kwakanangana nekupisa kwairi kupisa mafuta.Iyo yakawanda silinda yaunayo uye yakakura, iyo yakawanda mafuta mota inogona kupisa sekondi yega yega uye (inoretically kanenge) nekukurumidza iyo inogona kuenda.
Imwe nzira yekuita kuti mota iende nekukurumidza ndeyekuwedzera mamwe masilinda.Ndosaka mota dzemitambo dzinomhanya-mhanya kazhinji dziine masilinda masere negumi nembiri panzvimbo yemasilinda mana kana matanhatu mumotokari yemhuri.Imwe sarudzo ndeye kushandisa turbocharger, iyo inomanikidza mweya wakawanda kupinda mumasilinda sekondi yega yega kuitira kuti vapise mafuta nekukurumidza.Turbocharger iri nyore, yakachipa, yakawedzera chidimbu chekiti inogona kuwana simba rakawanda kubva muinjini imwe chete!
