Sei injini ichidhonza zvakanyanya panguva yekunaya, uye "inodya" zvakanyanya
Vatyairi vazhinji vanowanzoona marudzi ese ehunhu hunoenderana nemamiriro ekunze, dutu remagineti, huwandu hwemafuta mutangi, uye zviratidzo zvakafanana kuseri kwemotokari yavo. Mimwe yeiyi "tsika" yemotokari inogona kuverengerwa nyore kune manzwiro evaridzi, asi vamwe vane chinangwa chakakwana. Portal "AutoVzglyad" inotaura nezveimwe yemaitiro aya.
Tiri kutaura nezve shanduko yehunhu hweinjini panguva yekunaya. Icho chokwadi ndechekuti kana kuchinaya, hunyoro hwemhepo hwemhepo hunokurumidza kusvetuka kusvika kune hutsika.
Izvi zvinonyanya kucherechedzwa kana kupisa kwezhizha kunopisa mukati memaminitsi mashoma kunotsiviwa nemabhanan'ana nemvura inonaya. Zvinoshamisa, asi vatyairi vakasiyana vanoongorora shanduko muchimiro chekushanda kweinjini yemotokari yavo panguva yekunaya nenzira yakanyatsopesana. Vamwe vanoti mota yave nani kutyaira, uye injini iri kuwedzera simba nekukurumidza uye nyore. Vadzivisi vavo, pane zvinopesana, vanocherechedza kuti mumvura injini "inodhonza" zvakanyanya uye "inodya" mafuta akawanda. Ndiani akarurama?
Vatsigiri vezvakanakira kunaya kwemvura vanowanzoita nharo dzinotevera. Kutanga, musanganiswa wehuni ine yakakwira yemhute yemvura inopisa "zvinyoro", sezvo mwando unofungidzirwa kudzivirira detonation. Pamusana pekusavapo kwayo, kushanda kwechikwata chemagetsi chiri kukura, uye chinobudisa simba rakawanda. Chechipiri, masensa ekuyerera kwemhepo yakawanda, inoratidzika, nekuda kwehukuru hwayo hwekupisa uye kupisa kwemhepo mumvura inonaya, inoshandura zvishoma kuverenga kwavo, kumanikidzira injini yekudzivirira injini kupinza mamwe mafuta mumasilinda. Nokudaro, vanoti, kuwedzera kwesimba.
Ivo varidzi vemotokari vakafanana vanorangarira zviri nani izvo zvekutanga fizikisi vane maonero ekuti mumvura inonaya kubva mumotokari, pane kudaro, unogona kutarisira kurasikirwa kwesimba.
Nharo dzavo dzinobva pamitemo inokosha. Ichokwadi ndechokuti panguva imwechete yekushisa uye mhepo yemhepo, chikamu cheokisijeni mumhepo, zvimwe zvinhu zvakaenzana, zvichange zvisingashanduki. Iyo yakawanda yemhepo inoyerera sensor inozopa iyo injini yekudzora unit ine data kuverenga huwandu hweokisijeni - kugadzirira iyo yakakwana mafuta musanganiswa. Zvino fungidzira kuti hunyoro hwemhepo hwakasvetuka zvakanyanya.
Kana iwe ukatsanangura "paminwe", ipapo mhute yemvura yakangoerekana yaonekwa mairi yakatora chikamu che "nzvimbo" iyo yaimbova yakagarwa neokisijeni. Asi iyo mass air flow sensor haigone kuziva nezve izvi. Ndiko kuti, nehunyoro hwepamusoro panguva yekunaya, oksijeni shoma inopinda mumasilinda. Injini yekudzora unit inocherechedza izvi nekushandura kuverenga kwe lambda probe uye, maererano naizvozvo, inoderedza mafuta ekugovera kuitira kuti usapisa zvakanyanya. Somugumisiro, zvinoitika kuti pahupamhi hunyoro hunyoro, injini haishande sezvainogona, kuwana "ration" yekucheka, uye mutyairi, zvechokwadi, anonzwa izvi.
