Product catalog summary

Specifications
The N5.180 CR2 propulsion engine delivers a power output of 134 kW (182 hp) at the crankshaft with a displacement of 4.5 liters. It features a 4-cylinder inline configuration with 4 valves per cylinder and operates on a 4-stroke diesel cycle. The engine has a bore and stroke of 106.4 x 127 mm and a compression ratio of 16.7:1. It achieves a rated speed of 2400 rpm and an idle speed of 600 rpm, with a peak torque of 604 Nm at 2000 rpm. The engine's dry weight is 578 kg, and it is based on a John Deere engine platform. The fuel system is a high-pressure common rail with electronic control, and the air intake is turbocharged with an air-to-coolant aftercooler. The cooling system is closed with a heat exchanger, and the engine can be mounted at a 12° front up or 0° front down angle. It includes a 24 Volt, 50 Amp alternator and complies with IMO Marpol Annex VI, NRMM Tier 3, and EPA marine Tier 3 emissions standards.

Technical Description
The engine block includes replaceable wet-type cylinder liners and a water-cooled exhaust manifold. The fuel system features a common rail injection system, fuel heater, and primary and secondary fuel filters. The lubrication system includes 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 50A alternator, 24 Volt starter motor, and complete instrumentation with key switch and alarms. The air intake is turbocharged with an air-to-coolant aftercooler. Other features include a flywheel SAE 3, internal balancers, 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, and power take-off.

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.
