Kunezinhlobo ezimbili zabantu emhlabeni. : lezo ezidumisa imoto bese zilinda ngesineke injini ifinyelele izinga lokushisa elivamile lokusebenza, nalezo eziqala ngokushesha lapho imoto iqalwa. Ngakho yikuphi ukuziphatha okulungile? Ukuze uphendule lo mbuzo, u-Jason Fenske - ovela ku-Engineering Explained channel - ubeke ikhamera eshisayo enjini ye-Subaru Crosstrek yakhe.
Ngaphezu kokusiza ukugcina injini igcobile, uwoyela ubalulekile kunqubo yokwandisa izinga lokushisa kwenjini , futhi kuye ngokuthi i-viscosity yayo, kungase kungadingeki ngisho nokulinda injini ukuthi ifudumale ngokungenzi lutho. Njengoba sesichazile kulesi sihloko, ukusheshisa ngokungenangqondo ngethemba lokufudumala injini ngokushesha kungaba yingozi, njengoba injini ingashisi ngokwanele, futhi ngenxa yalokho uwoyela awekho, okwenza uwoyela ungagcobi. ngendlela efanele nokwandisa ukuguga/ukungqubuzana kwangaphakathi.
Kulokhu, ngezinga lokushisa elizungezile elingu-6 degrees Celsius, injini ye-Subaru Crosstrek ithathe imizuzu engaphezudlwana nje kwe-5 ukufinyelela izinga lokushisa elifanele lokusebenza. Buka ividiyo engezansi ukuze uthole incazelo enemininingwane eyengeziwe:
Manje ngesi-Portuguese esihle...
Ngaphandle uma izinga lokushisa langaphandle liphansi kakhulu, enjinini yesimanje futhi enohlobo olufanele lukawoyela asikho isidingo sokulinda ukuthi ifudumale uma ingenzi lutho . Kodwa qaphela: emizuzwini embalwa yokuqala yokushayela, kufanele sigweme ukusheshisa okungazelelwe, ukuyisa injini ebangeni eliphezulu le-rpm.
