Izizathu ezi-5 zokuthi kungani injini ingavele "ishaye iminwe"
Abaningi baye baqaphela ukuthi lapho injini isebenza, umsindo we-metallic othambile uzwakala ngokuzumayo, lapho abashayeli abanolwazi baqaphela ngokushesha ngokuthi "iminwe engqongqozayo". Futhi kunezimo lapho ukukhala kucishe kumise ukusebenza kwenjini. Ukuthi iculo elinjalo lingakhuluma ngani, ingosi ye-AvtoVzglyad ithi.
Ake siqale ngethiyori encane. Iphinikhodi ye-piston, okuyimbangela yokukhala, iyi-axis yensimbi ngaphakathi kwekhanda le-piston ukuze ivikele induku yokuxhuma. Uhlobo olunjalo lwehinge likuvumela ukuthi udale ukuxhumana okunyakazayo, okudluliselwa kuwo wonke umthwalo ngesikhathi sokusebenza kwesilinda. Isixazululo ngokwaso sinokwethenjelwa, kodwa futhi siyehluleka.
Ngokuvamile lokhu kwenzeka lapho izingxenye zenjini seziguge kakhulu. Noma okuhlukile kungenzeka lapho kungqongqoza kuvela ngemuva kokulungiswa kwemisebenzi yezandla. Isibonelo, abadwebi bakhetha izingxenye zesayizi ezingalungile futhi ngenxa yalokhu, iminwe ayihambisani nesihlalo. Ngenxa yalokho, kutholakala ama-backlashes, ukudlidliza kuyanda, imisindo engaphandle iyahamba. Uma unganaki lokhu, izingxenye ezintsha nazo zizoba nokugqoka okunzima, okuzodingeka kushintshwe futhi.
Izingcweti ezinolwazi zinquma umsindo weminwe ngendlebe. Uma i-motor igugile, khona-ke amadivaysi akhethekile awadingeki kulokhu, kodwa uma inkinga isanda kuvela, basebenzisa i-stethoscope, bayisebenzise ezindongeni ze-cylinder block. Ngendlela, ngisho nezokwelapha zifanelekile, ngoba zilalela iyunithi ngokufanisa, njengesiguli esigulayo.
Esinye isizathu esivamile sisekuqhunyisweni kwenjini ngenxa yezinga eliphansi likaphethiloli noma ngisho nophethiloli “oculiwe”. Ngamafutha anjalo, ukuqhuma kwangaphambi kwesikhathi kwengxube ye-air-fuel kwenzeka, okuvimbela i-piston ukuthi isebenze ngendlela efanele. Ngenxa yalokho, i-piston skirts ngokumelene nezindonga zomkhono. Yilapho ukukhala kwensimbi kuvela khona, ikakhulukazi ngesikhathi sokusheshisa. Uma uqala inkinga, khona-ke ama-scuffs avela ezindongeni zamasilinda, okuletha injini eduze nokulungiswa okukhulu.
Khumbula ukuthi i-detonation ayenzeki kusilinda esisodwa, kodwa eziningana ngesikhathi esisodwa. Ngakho-ke, imiphumela yayo izobonakala kuwo wonke injini.
Okokugcina, i-metallic knocking kungenzeka uma injini ivalwe ngamadiphozithi. Ngenxa yalokhu, ikhanda le-piston liyasuswa futhi lisontekile, futhi isiketi salo sishaya odongeni lwesilinda. Lokhu kuhambisana nokundindizela okunamandla, njengokungathi injini inyakaza ngamandla angaziwa.
