Reduce the environmental footprint and gradually achieve zero emissions.”
QSZ13 high-power inline 6-cylinder engine, with a displacement of 13 liters and a maximum output of 800 horsepower. This model is a high-quality product developed over two years by the marine engine development teams of Chongqing Cummins and Dongfeng Cummins, relying on Cummins’ local advanced R&D resources and manufacturing processes in China. Suitable for high-speed boat applications such as yachts, government service ships, and leisure fishing boats. It meets China’s Phase II and IMO Tier II emission standards, and has the ability to meet stringent emission standards such as US EPA Tier III, EU EU3A, and RCD2.
QSZ13 integrates many leading technologies of Cummins diesel engine.

Together with optimized low-temperature intercooling technology, they can meet the requirements of many ship emission regulations. The excellent engine structural design not only meets the requirements of lightweighting, but also ensures reliability under high power output conditions.
The truck equipped with this model has participated in the Dakar Rally and won both first and second place. The engine performance is mature and reliable. With the advantages of localized production and local supply chain, QSZ13 has unique advantages in product delivery and product after-sales. Relying on Cummins’ comprehensive after-sales service network, it brings users a more convenient service experience and more advantageous maintenance costs.
