Ngokuthuthuka okuqhubekayo kwenqubo yezimboni zaseChina, inkomba yokungcoliswa komoya isiqalile ukukhuphuka, futhi kuyaphuthuma ukuthuthukisa ukungcoliswa kwemvelo.Ukubhekana nalolu chungechunge lwezinkinga, uhulumeni waseShayina usethule ngokushesha izinqubomgomo eziningi ezifanele mayelana nokukhipha umoya wenjini kadizili.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 isho isistimu yokuphakela uphethiloli ehlukanisa ngokuphelele ukukhiqizwa komjovo kanye nenqubo yomjovo ohlelweni lwe-loop oluvaliwe oluhlanganiswe nephampu kaphethiloli enengcindezi ephezulu, inzwa yokucindezela kanye neyunithi yokulawula kagesi (ECU) .Izinjini zikadizili ezilawulwa nge-elekthronikhi azisanciki ekujuleni kwe-throttle yomshayeli ukuze zilawule umthamo womjovo kaphethiloli wephampu engumshini, kodwa zithembele ku-ECU yenjini ukucubungula ulwazi lwawo wonke umshini.I-ECU izoqapha isimo sesikhathi sangempela senjini ngesikhathi sangempela futhi ilungise umjovo kaphethiloli ngokwendawo ye-accelerator pedal.Isikhathi kanye 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.
