Nanni N9.380 CR2 Marine Diesel Engine The Nanni N9.380 CR2, engineered by Nanni Industries SAS, is a robust marine diesel engine tailored for propulsion in demanding nautical environments. This inline-six powerhouse delivers dependable, high-torque performance, making it an ideal choice for vessels requiring efficient and reliable power delivery. Key technical specifications underscore its engineering excellence: It produces 380 horsepower (279 kW) at the crankshaft, with a displacement of 9.8 liters (9,800 cm³) across six cylinders. Turbocharged with an intercooler for optimized air intake, the engine features a precision common-rail fuel injection system (CR2 designation) for superior combustion control. Operating at a maximum speed of 2,200 rpm under an M2 rating, it ensures balanced performance while adhering to stringent emission standards, including IMO Annex VI, EPA Marine Tier 3, and NRMM 97/68/EC compliance. The symmetrical cylinder block and corrosion-resistant construction enhance longevity in saltwater conditions. In marine applications, the N9.380 CR2 excels with its high power-to-weight ratio and fuel-efficient design, minimizing operational costs on extended voyages. The turbo-intercooler system reduces exhaust temperatures and vibrations, promoting smoother operation that safeguards passenger comfort and driveline components against the rigors of waves, humidity, and constant motion. Its direct injection technology optimizes fuel atomization, lowering emissions and boosting thermal efficiency for sustainable seafaring. Performance-wise, the engine strikes an optimal balance between responsive acceleration for maneuvering in tight harbors and sustained cruising speeds for open-water reliability, all while maintaining low noise and vibration levels inherent to its inline configuration. Suited for medium- to large-sized vessels, the N9.380 CR2 thrives in yachts, fishing trawlers, and commercial workboats, empowering operators with versatile propulsion that combines raw power, endurance, and environmental responsibility for seamless nautical adventures.
