Product catalog summary

Specifications
The N6.270 E propulsion engine delivers a power output of 199 kW (271 hp) at the crankshaft with a displacement of 6.8 liters. It features a 6-cylinder inline configuration and operates as a 4-stroke diesel engine. The bore and stroke measure 106.4 x 127 mm, with a compression ratio of 17.0:1. The engine's rated speed is 2500 rpm, with an idle speed of 650 rpm. It achieves peak torque of 975 Nm at 1800 rpm. The dry weight of the engine is 735 kg, and it is based on a John Deere engine. The fuel system includes a rotary fuel injection pump that is electronically controlled, and the air intake is turbocharged with an air-to-seawater aftercooler. The cooling system is closed with a heat exchanger, and the engine can be mounted at angles of 9° front up or 0° front down. The alternator is rated at 24 volts and 50 amps, with emission compliance to IMO Marpol Annex VI and NRMM Tier 2 standards.

Technical Description
The engine block features replaceable wet-type cylinder liners and a water-cooled exhaust manifold. The fuel system includes a fuel filter and a mechanical fuel injection pump that is electronically controlled. The lubrication system has a replaceable full-flow oil filter, oil dipstick, and oil cooler. The cooling system includes a gear-driven self-priming raw water pump, coolant circulating pump, and water-cooled exhaust elbow. The electrical system includes a 24V 50A alternator, a 24-volt starter motor, and complete instrumentation with key switch and alarms. The air intake is turbocharged with an air-to-seawater aftercooler. Other features include a flywheel SAE 3, flexible engine mounting, and a damper pulley.

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 3000 annual operating hours with a load factor up to 40%. Full power can be used for no more than 1 hour out of each 12 hours of operation, with the remaining time at or below cruising speed.
