YUCHAI YCDV254FHZ-50
·The main structures, such as engine body, are time-tested, which ensuresthe high reliability of the whole engine.
·The design of integrated outlet water header pipe of cylinder head is adopt-ed, which reduces the sealing surface and improves sealing reliability.
·Leading and mature HPCR fuel system and high-efficient turbochargedintercooled technologies are adopted, which ensure precise control offuel-injection quantity and sufficient air intake; and the full combustion, lowfuel consumption and less emission of diesel engine under different loadconditions are ensured
·Good transient speed regulation and strong loading capacity , require-ments for Grade G3 generator set performance is satisfied.
