The core advantage of the cumins 6CTA8.3-M260HP ferry/cargo ship motor comes from the advanced inline six-cylinder design. Each cylinder has a diameter of 114mm, a stroke of 135mm, and a displacement of 8.3L. At a rated speed of 1800rpm, it can output a stable power of 260HP (194kW) and a maximum torque of up to 1080N・m@1200rpm.

product Technical highlights
The marine version uses nano-ceramic cylinder liner technology for the first time
Intelligent wave compensation fuel injection system
Three-proof (mildew/salt/moisture-proof) electrical components
Quick disassembly and maintenance module design
The cumins 6CTA8.3-M260HP ferry/cargo ship motor, the innovative PT-CRS fuel system adopts electronically controlled single pump technology, with an injection pressure of 100MPa, and a four-valve cylinder head design, which makes the fuel atomization more uniform and improves the combustion efficiency by 12%. According to third-party testing, the fuel consumption rate of the engine is as low as 208g/kW・h, saving 6%-8% fuel cost compared with products of the same level.
Cumins 6CTA8.3-M260HP ferry/cargo ship motor high-strength alloy cast iron cylinder block has been optimized through finite element analysis, and its deformation resistance has been increased by 25%. The anti-corrosion coating that has passed the 500-hour salt spray test has extended the service life of the engine to more than 15 years in a humid marine environment.
