Products
1.High reliability
The engine block and cylinder head are made of alloy cast iron, with high strength; the integral forged steel crankshaft and the sliding bearing make the product highly reliable, small in size, and light in weight; the overhaul period is over 15000 hours.
2.Energy saving and environmental friendliness
The application of the four-valve technology and Yuchai's patented combustion technology ensures the combustion and emission optimization and more adequate combustion. The HPCR system, high-performance combustion chamber, and intake swirl make the fuel consumption index far superior to that of domestic products at the same power level. The application of full electronically-control technology makes the product meet China II and IMO II emission standards for marine engines.
3.Safety and comfort
Digital intelligent local and remote monitoring instruments are equipped to monitor and protect the operation of the engine in real time; the equipped integral cast iron fresh water cooling jacket exhaust pipe ensures lower cabin temperature, safer use, stable operation, and low noise and vibration.
4.High adaptability
It has automatic and manual parallel functions, with its performance meeting the relevant provisions of the General Technical Condition for Marine Diesel Generator Sets (GB/T13032-2010).
