Advantages of 6CTA8.3-M220 Marine Engine

1. Advanced design, exquisite manufacturing technology, reliable and durable, suitable for high-strength and heavy-duty operations under severe working conditions.
2. Using high-pressure fuel pump, combustion is more complete under high fuel injection pressure, less energy loss, strong power, strong fuel adaptability, and lower emissions.
3. Adopt Holset supercharger with integral wastegate valve, low speed responsiveness and strong power.
4. Integral cylinder design, the number of parts is about 25% less than similar products, the failure rate is lower, and the maintenance is more convenient.
5. The cylinder liner adopts a platform mesh honing design and a corrosion-resistant high-nickel cast iron piston, which greatly reduces oil loss, enhances durability, and has a longer service life.
