Ngokuthuthuka okuqhubekayo kwenqubo yezimboni zaseShayina, inkomba yokungcoliswa komoya isiqalile ukukhuphuka, futhi kuyaphuthuma ukuthuthukisa ukungcoliswa kwemvelo. Ukubhekana nalolu chungechunge lwezinkinga, uhulumeni wase-China usethule ngokushesha izinqubomgomo eziningi ezifanele mayelana nokukhipha umoya wezinjini zikadizili. Phakathi kwazo, izinjini ezivamile zikadizili ezinengcindezi kajantshi we-National III kanye ne-Euro III emakethe yesethi yamajeneretha kadizili ziya ngokuya zithandwa emakethe.
Injini ye-diesel ye-high-pressure common ibhekisela ohlelweni lokuhlinzeka ngophethiloli oluhlukanisa ngokuphelele ukukhiqizwa komjovo kanye nenqubo yomjovo ohlelweni oluvaliwe oluhlanganiswe nephampu yamafutha okucindezela okukhulu, inzwa yokucindezela kanye neyunithi yokulawula i-electronic (ECU). I-ECU izoqapha isimo sesikhathi sangempela senjini ngesikhathi sangempela futhi ilungise umjovo kaphethiloli ngokwendawo ye-accelerator pedal. Isikhathi nevolumu yokujova uphethiloli. Namuhla, izinjini zikadizili zisetshenziswa kakhulu ohlelweni lwesizukulwane sesithathu “lokulawula ingcindezi yesikhathi”, okungukuthi, ujantshi ovamile wokucindezela okukhulu.
Izinzuzo zezinjini ezivamile zikadizili ezinomfutho ophezulu wokusebenzisa uphethiloli, ukwethembeka okuphezulu, impilo ende, kanye netorque ephezulu. Izinjini zikadizili ezinojantshi ojwayelekile zikhipha amagesi ayingozi kakhulu kunezinjini ezingenawo ujantshi ojwayelekile (ikakhulukazi i-CO engaphansi), ngakho zinobungani bemvelo uma ziqhathaniswa nezinjini zikaphethiloli.
Ububi bezinjini ezivamile zikadizili ezisezingeni eliphezulu zihlanganisa izindleko eziphezulu zokukhiqiza nezokulungisa (izintengo), umsindo ophezulu, nobunzima bokuqalisa. Uma injini isebenza isikhathi eside, izinga lokushisa lenjini nomfutho liphezulu, futhi kuzokhiqizwa umule ne-coke eyengeziwe kumasilinda, futhi uwoyela wenjini nawo uthambekele ekubeni ne-oxidation ukuze ukhiqize izinsini. Ngakho-ke, uwoyela wenjini kadizili udinga umshini wokushisa osezingeni eliphezulu.
