Kampaniyo idakhazikitsidwa mu 2007, ukadaulo umachokera pakukhazikitsa injini ya dizilo ya D28, kudzera mu kafukufuku wopitilira wakunja ndi maphunziro ndi kuitanitsa makina onse (CBU), gulu la magawo (CKD), kukhazikika ndi njira zina, kupanga amphamvu. luso mlingo, mgwirizano wamphamvu wa gulu ogwira ntchito. Kukula kosalekeza kwa msika wamagalimoto, ukadaulo wapamwamba wopanga, zida zopangira zida zamakono, luso lazowongolera zopanga, njira zamakono zoyesera kuti apange mtundu wamagetsi wamagetsi wa Wiman. Zogulitsa kuchokera ku kamangidwe, kugula, ndondomeko, malo, khalidwe ndi zina zoyendetsera bwino, komanso mogwirizana ndi zofunikira za dziko ndi zapadziko lonse zomwe zimapangidwa ndi kupanga. Kampaniyo yadutsa chiphaso cha TS16949 system.
Zogulitsa za Weiman Power zikuphatikiza 7-30L zopulumutsa mphamvu komanso chitetezo cha chilengedwe ma injini a dizilo amphamvu kwambiri, kuphimba mphamvu 84-1150kW, mitundu yosiyanasiyana ya injini za dizilo kudzera pa certification ya 3, national 4 ndi Tier2, Tier3 stage emission certification. Zogulitsa zimagwiritsidwa ntchito kwambiri pamagalimoto olemera, magalimoto opangira zida zapadera, mabasi akulu, magalimoto amisiri, makina omanga, ma jenereta ndi zolinga zina.
Wieman D mndandanda wa injini ya dizilo idayambitsa ndikutengera mapangidwe apamwamba a injini zaku Europe ndi America, zida zopangira zida zapamwamba, luso loyendetsa bwino lopanga. Pazida za hardware, sonkhanitsani zigawozo, kuchotsani zolakwika, ndipo injini imagwiritsa ntchito kuyesa kulimba kwa mpweya kuti muwonetsetse kuti injini ilibe mavuto atatu otuluka. Makonzedwe a V-woboola pakati, chiŵerengero chake chochepa cha kuponderezedwa, luso la kulimbikitsana kwamagulu, kwa nthawi yaitali lakhala lopangidwa ndi kudalirika kwakukulu, mphamvu yamphamvu, phokoso lochepa ndi ubwino wina, kuyika kwa mankhwala ndikosavuta, kulakwitsa kochepa, kukonza kosavuta, kugwiritsidwa ntchito mu kutentha, kuzizira ndi chilala ndi zina zanyengo nyengo m'dera, ndi mphamvu yabwino ya jenereta anapereka.
