CCEC KT38–D(M)679 Marine Engine Product Advantages

Excellent Durability
The cylinder block and head adopt high-strength integrated design, reducing failure rates. Durable and has earned an excellent reputation.

Outstanding Performance
Equipped with an advanced PT fuel system and ultra-high injection pressure, it features unique advantages such as overspeed protection, low-pressure fuel supply, fewer pipelines, and low failure rates. This ensures optimal fuel atomization and efficient combustion, delivering high energy-saving performance. The STC oil timing control valve precisely adjusts timing, improving combustion and reducing smoke emissions during low-idle conditions.

Exhaust System
Chongqing Cummins marine engines are designed with a rational exhaust system. The wet turbocharger and water-cooled exhaust pipes effectively reduce surface temperatures, complying with SOLAS safety regulations.

Easy Maintenance
Modular design with compact and integrated components. Parts are detachable with high reusability. Shared platform design ensures high parts commonality.

Emission Compliance
Compliant with IMO Tier II emission standards. Features a marine-optimized turbocharger and intercooler from Chongqing Cummins, paired with low-temperature intercooling technology. This enhances operational efficiency, reduces fuel consumption and emissions, and improves engine reliability.

Classification Society Certifications
Certified by multiple international classification societies, including CCS and BV.
