I-Infiniti's 2019 QX50 iyimoto yokuqala ohlwini lwabo ukufaka eyabo I-VC-Turbo Injini (ye-Variable-Compression) engashintsha ukulinganiswa kokucindezelwa endizeni ukuze kwandiswe ukusebenza kahle kukaphethiloli. Izimoto ezijwayelekile zivamise ukuba nesilinganiso esisodwa sokucindezelwa esivezwa ngendlela efana no-10: 1, oqhathanisa ubukhulu nenani eliphansi levolumu yesilinda njengoba i-piston ihamba kuwo wonke umjikelezo wayo. Kalula nje, imithwalo ephakeme idinga ukulinganisa okuphansi ukugcina ukusebenza kahle, futhi okuphambene nalokho.
Injini isebenza isebenzisa ikhompiyutha ekhombisa imoto kagesi ehambisa ingalo ye-actuator ukunciphisa ukufinyeleleka kwama-piston ngaphakathi kwenjini, okwehlisa isilinganiso sokucindezelwa ngezikhathi lapho kusetshenziswa amandla aphezulu we-turbo, okwenza imoto yande amandla kagesi. Lapho imoto ingasebenzisi i-turbocharger kaningi, ingalo ye-actuator yandisa ukuhamba kwamapiston, okukhuphula isilinganiso sokucindezelwa.
Injini ye-VC-T nayo ingasebenza kufayela le- Umjikelezo we-Atkinson ukuqhubekisela phambili ukusebenza kahle, okusebenza ngokuvula kancane amavalvu wokungenisa izinjini, ukudonsela umoya owengeziwe emagumbini omlilo ngasikhathi sinye ama-piston aqala ukucindezela ingxube kaphethiloli womoya. Lokhu kuvumela injini ukuthi isebenze ngokufana nemoto encane, esebenza kahle lapho amandla we-turbo engadingeki.
Lapho ukuthungela kwemoto kuqhubeka, i-VC-T ikhiqiza amandla njengenjini enkulu, futhi uma iba ngaphansi kwengcindezi ephezulu, ishintshela kumjikelezo we-Atkinson njengoba imoto inamandla anele okusindisa, ngaleyo ndlela igcina ukusebenza kwayo kahle. Injini yakwa-Infiniti i-VC-T okwamanje itholakala kuphela ku-2019 QX50 yenkampani, kepha singalindela ukuyibona kuhlu lwangakusasa lwe-Infiniti.
