In the field of marine engine applications, We are also constantly exploring and improving existing engine technology, using low-carbon emission technology, intelligent control systems and more advanced materials to improve fuel efficiency and operating efficiency, and reduce emissions of pollutants including carbon dioxide, nitrogen oxides and particulate matter. Reduce the environmental footprint and gradually achieve zero emissions.”
QSZ marine engine
Timely supplement of yacht power
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.
Cummins QSZ13 marine engine QSZ13 integrates many leading technologies of Cummins diesel engine. The ultra-high pressure fuel injection system (XPI) and Quantum electronic control system and efficient HOLSET supercharger developed by Cummins ensure excellent power performance and fuel economy. 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 light weighting, 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.
QSK50 marine engines （Localized production in China ）
Close to customer needs
As a 16-cylinder four-stroke high-speed, low-emission, high-horsepower diesel engine, the QSK50 has a cylinder bore and stroke of 159 mm, with a power coverage ranging from 1,700 horsepower to 2,200 horsepower. It can be used for ship power generation or ship propulsion, and has Certification from the world's major classification societies ABS, BV, DNV, CCS and LR.
Chongqing Cummins QSK50 marine engine
QSK50 has been widely used in government service ships, offshore engineering, ferries, wind power and engineering ships, and has won unanimous praise from users. In order to better serve the Chinese marine machinery market and customers, Cummins will introduce QSK50 into the Chinese production system in 2023 and officially put it into production at Cummins' new high-horsepower factory in Chongqing. In addition to being completely consistent with Cummins' global production system in terms of manufacturing and quality control standards, the QSK50 engine produced by Chongqing Cummins has further improved its power according to the needs of the Chinese market, greatly shortened the delivery time, and better met the diverse customization needs of domestic customers.
