1. Ukwethembeka okuphezulu

Izingxenye ezibalulekile neziyingxenye ezifana nebhulokhi yenjini, ikhanda le-cylinder, i-crankshaft, i-bearing bush, ne-gearbox zifana nalezo zenjini kadizili, okwenza umkhiqizo ube nethembeke kakhulu. Ngaleso sikhathi, ingcindezi yokushiswa nokuqhuma kwenjini kagesi ingaphansi ngo-20% ~ 30% kunaleyo yedizili, iqinisekisa umkhawulo omkhulu wokwethenjwa. Indandatho yepiston iphathwa nge-nitriding, ithuthukisa ukumelana nokuguga.

2. Ukusebenza okuphezulu kanye nobuhle bemvelo

Injini kagesi inemisebe ye-carbon ephansi uma iqhathaniswa nenjini kadizili ezingeni lamandla elifanayo. Injini kagesi inemisebe ye-carbon ephansi uma iqhathaniswa nenjini kadizili ezingeni lamandla elifanayo. Cishe akukho misebe ye-PM ne-sulfide; imisebe ye-HC, CO, ne-NOx ihlangabezana nezimfuneko zemithetho yezinga lokukhishwa kwemikhumbi i-China II.

3. Umklamo ophelele wesiqinisekiso sokuphepha

I-intake manifold inikezwe kahle ngomshini wokuvimbela ukuqhuma komoya ukuze kuqinisekiswe ingcindezi ephephile nelawulwa yomgodi wokungena ngesikhathi sokusebenza komshini. Umklamo wokuvimbela ukuqhuma kwe-crankcase: Umshini okhethekile wokuvimbela ukuqhuma unikezwa ohlangothini lwe-crankcase yomshini ukuze kuqinisekiswe ukuthi ingcindezi ye-crankcase ingaphakathi kwebanga elamukelekayo.

4. Ukulawula okuthuthukisiwe kokushisa

Ubuchwepheshe bokushisa obuqinile obunama-turbocharger & intercooled buqinisekisa ukushisa okusebenzayo nokuhlanzekile kanye nomnotho omuhle. Ubuchwepheshe bokulawula ama-turbocharger nge-elektroniki kanye nobuchwepheshe bokudlula ama-turbocharger buqinisekisa ukulawulwa okunembayo kwengcindezi ye-turbocharged kanye nokuphendula okuthuthukisiwe komshini. Ubuchwepheshe bokulawula okujikelezayo kwenzwa ye-oxygen buvumela ukulawulwa okunembayo kwesilinganiso somoya-futhi kanye nokusebenza okuthuthukisiwe nokuzinza komshini. Ubuchwepheshe bokuvutha okuphezulu buqinisekisa amandla okukhanyisa andisiwe, ukushisa okusheshayo komshini okusheshayo, kanye nomnotho ongcono.
