Weichai X170 Series of Marine Diesel Engine 258Kw-601Kw
X170ZC series marine diesel engines (including X6170ZC series, 8170ZC series) come from the former 170Z series. After a betterment of both design and quality, the new series consist of 6-cylinder and 8-cylinder engines. With an optimized configuration of supercharger, high-pressure oil pump, oil injector, intake pipe, and combustion chamber, the new series excel themselves in power coverage, oil efficiency, emission, and quick start-up. In the meantime, an improvement of engine block, cylinder liner, exhaust pipe and oil pan has further enhanced its reliability and performance and made it easier to operate and maintain.
The X170ZC series have passed the International Association Classification Society Certificates of CCS, ZY, ABS, GL, BV, DNV , RS and LR. Besides, it complies with IMO Tier II emission standard.
This series can be widely used on offshore and river fishing boats, transport ships and engineering vessels. Power Range: 258-601kW Rotation Speed: 1,000-1,500r/min
