1. Ukwethembeka okuphezulu

Izingxenye ezibalulekile neziyingxenye ezifana nebhulokhi yenjini, i-crankshaft, i-connecting rod, i-bearing bush, kanye ne-gear train zifana nalezo zenjini kadizili, okwenza umkhiqizo uthembeke kakhulu. Ngaleso sikhathi, ingcindezi yokushisa nokuqhuma kwenjini kaphethiloli ingaphansi ngo-20% ~ 30% kunaleyo kadizili, iqinisekisa umkhawulo omkhulu wokuthembeka.

2.Ukusebenza okuphezulu kanye nokuba nobuhlobo nemvelo

Injini kaphethroli inemikhiqizo ye-carbon ephansi uma iqhathaniswa nenjini kaphethiloli ezingeni lamandla elifanayo. Cishe akukho ukukhishwa kwe-PM ne-sulfide. Ukukhishwa kwe-HC, i-CO, ne-NOx kuhlangabezana nezimfuneko zokulawula ezijwayelekile ze-China II zokukhishwa kwemikhumbi.

3. Umklamo ophelele wesiqinisekiso sokuphepha

Umklamo wokuvimbela ukuqhuma kwe-crankcase: Kunikezwe ivolovula ekhethekile yokuvimbela ukuqhuma ohlangothini lwe-crankcase ukuqinisekisa ukuthi ingcindezi ye-crankcase ingaphakathi kwebanga elamukelekayo. Umklamo wokuqapha izinga lokushisa lokukhipha umoya: Inzwa yokushisa yokukhipha umoya yakhelwe ukuqapha izinga lokushisa lokukhipha umoya enjinini, iqinisekisa ukuphepha kwayo enjinini. Ipayipi lokukhipha umoya elipholiswa ngamanzi liqinisekisa ukukhishwa okuncane kokushisa, ukuncishiswa kwezinga lokushisa kwesigaba, nokufinyeleleka okuhle.

4. Ubuchwepheshe bokulawula ukushisa obuthuthukisiwe

Ubuchwepheshe bokushisa obunomoya opholiswe kahle obune-turbocharger buqinisekisa ukushisa okusebenzayo nokuhlanzekile kanye nomnotho omuhle. Ubuchwepheshe bokulawula i-turbocharging nge-elektroniki buqinisekisa ukulawula okunembayo kwengcindezi ye-turbocharged kanye nokuphendula okuthuthukisiwe kwenjini. Ubuchwepheshe bokulawula okuyindilinga nge-oxygen sensor buvumela ukulawula okunembayo kobudlelwano bomoya-nomlilo kanye nokusebenza okuthuthukisiwe nokuzinza kwenjini. Ubuchwepheshe bokuvutha obunamandla aphezulu buqinisekisa amandla okuthungela aphezulu, ukushisa okusheshayo kwenjini okusheshayo, kanye nomnotho ongcono.
