YUCHAI YC4D SERIES MARINE ENGINE
YUCHAI YC4D SERIES MARINE ENGINE
This series diesel engine developed with Germany marine technology.
Cylinder block, cylinder head use high strength alloy to cast manufacturing ,better rigid, with integral type crankshaft and sliding bearing ,small volume light weight, high reliability.Overhaul period is more than 10000 hours.
With high performance combustion chamber and the intake swirl, the fuel consumption is superior to domestic products
With Yuchai proprietary piston ring seal technology and valve seal technology lubricating oil consumption is lower than domestic power transmission products with more than 50%.
Is the ideal power for small ships and small fishing vessels and 24 ~40kW marine generator sets.
