Product catalog summary

Specifications
The N9.380 CR2 propulsion engine delivers a power output of 280 kW (381 hp) at the crankshaft with a displacement of 9 liters. It features a 6-cylinder inline configuration and operates on a 4-stroke diesel cycle. The engine has a bore and stroke of 118.4 x 136 mm and a compression ratio of 16.3:1. It achieves a rated speed of 2200 rpm and an idling speed of 650 rpm. The peak torque is 1572.8 Nm at 1700 rpm. The engine's dry weight is 948 kg, and it is based on a John Deere engine platform. The fuel system utilizes direct injection with a high-pressure common rail that is electronically controlled. The air intake system is turbocharged with an air-to-seawater aftercooler, and the cooling system is closed with a heat exchanger. The engine can be mounted at a maximum angle of 0° front up and 12° front down. It includes a 24 Volt, 100 Amp alternator and complies with IMO Annex VI, EPA marine Tier 3, and NRMM 97/68/EC emission standards.

Technical Description
The engine block features replaceable wet-type cylinder liners and 4 valves per cylinder, with a water-cooled exhaust manifold. The fuel system includes primary and secondary fuel filters and a common rail fuel injection system. The lubrication system has a replaceable full-flow oil filter, oil dipstick, and oil cooler. The cooling system is equipped with a gear-driven self-priming raw water pump, coolant circulating pump, and water-cooled exhaust elbow. The electrical system includes a 24V 100A alternator, a 24 Volt starter motor, and complete instrumentation with key switch and alarms. The air intake system features a water-cooled turbocharger and air-to-seawater aftercooler. Other features include a flywheel SAE 2, damper pulley, and flexible engine mounting.

Optional Equipment & Accessories
Options include keel cooling adaptation, dry exhaust elbow, complete marine propulsion systems, marine transmission adaptation kits, throttle and shift controls, additional instrumentation, flying bridge extension harness, rigid engine mounting, power take-off, and type approval.

Rating
The engine is rated for up to 5000 annual operating hours with a load factor up to 65%. Full power operation is limited to 16 hours out of each 24-hour period, with the remaining time at or below cruising speed.
