I-Yangdong Co., Ltd., inkampani engaphansi kwe-China YITUO Group Co., Ltd., iyinkampani esitokwe ehlangene egxile ocwaningweni nasekuthuthukisweni kwezinjini zikadizili nokukhiqizwa kwezingxenye zezimoto, kanye nebhizinisi kazwelonke lobuchwepheshe obuphezulu.
Ngo-1984, inkampani yathuthukisa ngempumelelo injini yokuqala kadizili engama-480 yezimoto eChina.Ngemuva kweminyaka engaphezu kwengu-20 yentuthuko, manje isingesinye sezisekelo ezinkulu zokukhiqiza injini ye-dizili enezinhlobo eziningi, imininingwane kanye nezikali e-China.Inamandla okukhiqiza izinjini ezingu-300000 zama-multi cylinder diesel ngonyaka.Kunezinhlobo ezingaphezu kuka-20 eziyisisekelo zezinjini ze-multi cylinder diesel, ezine-cylinder diameter engu-80-110mm, ezishintshayo zibe ngu-1.3-4.3l namandla afinyelela ku-10-150kw.Siqede ngempumelelo ucwaningo nokuthuthukiswa kwemikhiqizo yenjini kadizili ehlangabezana nezidingo ze-Euro III kanye nemithethonqubo yokukhipha umoya ye-Euro IV, futhi sinamalungelo aphelele azimele empahla yengqondo.Phakamisa injini ye-diesel enamandla aqinile, ukusebenza okuthembekile, umnotho nokuqina, ukudlidliza okuphansi nomsindo ophansi, isiphenduke amandla athandwayo kumakhasimende amaningi.
Le nkampani isiphumelele isitifiketi se-ISO9001 sesistimu yekhwalithi yamazwe ngamazwe kanye nesitifiketi sesistimu yekhwalithi ye-ISO / TS16949.Injini encane ye-multi cylinder diesel ithole isitifiketi sokukhululwa sokuhlolwa kwekhwalithi yomkhiqizo, futhi eminye imikhiqizo ithole isitifiketi se-EPA II sase-United States.
