1 YICHEONG POWER Technical Data Sheet: YC4D series Model Features: This series diesel engine is developed by Yuchai adopting the technology of FEV,Germany; The cylinder block and head are made of the alloyed cast iron; The engine uses the integral crankshaft and so it is featured by compact construction,lighter in weight and higher reliability;the overhaul life is more htan 0,000 hours. The engine uses the high performance combustion chamber and swirl intake and so it has the excellent fuel efficiency compared with products of the same power category at home; Yuchai particular piston ring seal technology reduces lubrication oil consumption by more than 50% compared with products of the same power category at home. It is used as the ideal main machine for powering small-sized marines and fishery vessels and as the ancillary machine for 20-40kw GEN-SETS.
