Umuvuduko muke moteri ya mazutu ya marine ebyiri, irangwa nubukungu bwiza no kwizerwa cyane, ikoreshwa cyane mumato manini, itwara hafi 70% yubunini bwimizigo kwisi kandi ikagira uruhare runini muri gahunda yubukungu bwisi. Umuvuduko muke moteri ya marine ya mazutu ifite imbaraga nyinshi kandi isohora ibintu byinshi byangiza. Umuryango mpuzamahanga w’amazi (IMO) watangiye gushyira mu bikorwa amahame yo mu cyiciro cya III mu turere tumwe na tumwe two kugenzura ibyuka bihumanya ikirere, bisaba ko moteri ya mazutu yo mu mazi ifite umuvuduko uri munsi ya 130r / min yohereza ibicuruzwa bitarenze 3.4g / (kW · h) bya NOx muri agace kagenzura imyuka ihumanya ikirere. Amato adashoboye kubahiriza ibipimo by’ibyuka bihumanya ikirere ahura n’uko adashobora kugenda mu nyanja mu bihugu bimwe na bimwe byateye imbere. Kugeza ubu, hari inzira ebyiri zingenzi za tekinike ya moteri yihuta ya moteri ya Marine yujuje ibyangombwa byoherezwa mu cyiciro cya III: (1) ikoreshwa rya catalitiki yatoranijwe (selivecatalyticreduction, SCR) ikoranabuhanga rya catalitike yo kugabanya NOx wongeyeho urea N2, ikeneye inyongera gushiraho ibikoresho byinshi nyuma yo gutunganya, nigiciro kinini cyo kubungabunga; . Mu myaka yashize hamwe nogukoresha bwa mbere tekinoroji yumuvuduko mwinshi wa gari ya moshi mumuvuduko muke wa moteri ya Marine kunoza imiterere ya sisitemu yo gutera inshinge hamwe ningamba zo gutera inshinge byagaragaye ko bifite imbaraga nyinshi zo kunoza amavuta ya silindiri hamwe na gaze no kuvanga no gutwika. Mu buvanganzo algorithm ya micro-genetique ikoreshwa mugutezimbere ibipimo byabanjirije gutera inshinge kandi ugasanga ingamba zikwiye mbere yo gutera inshinge zishobora kugabanya igihe cyo gutinda gutwika kuzamura imikorere yumuriro no kugabanya gukoresha lisansi neza.
