99 - 185 kW, 60 Hz @ 1800 RPM 80 - 155 kW, 50 Hz @ 1500 RPM Aftercooled For High Power Density A Northern Lights exclusive. No other set builder has aftercooled this engine! All A and H models have an aftercooler that cools the intake air. Cool air has more oxygen for better combustion. This after-cooler, along with electronically controlled fuel injection, give you more kW output. Electronic System Profiler “ESP” is a window to your set’s real time operating condition. The ECU that controls the electronic fuel injection produces a SAE J1939 data stream of engine information that can be shown on an optional CAN Bus monitor panel. Component Specific Features Engine Block • Lugger six cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesel based on heavy-duty industrial engine block. • Balanced, forged, hardened crankshaft with induction hardened journals and rolled fillets. • Bimetallic valves have chrome stems & rotators. • Replaceable valve seats and guides. • Three ring aluminum alloy pistons with Ni-Resist insert for the top ring. Keystone piston ring reduces carbon buildup under light loads. • Torsional crankshaft vibration damper for smooth operation. • 8 groove, poly-vee drive belt powers the DC alternator & freshwater coolant system pump. • Replaceable, wet cylinder liners for long life and low rebuild costs. Fuel System • Direct fuel injection systems (see feature box below) • Ring clamp fuel lter with air bleed and drain. • Diaphragm-type, mechanically driven fuel transfer pump with manual priming lever. Electric fuel transfer pump on “A2, A3”. • Flexible fuel lines routed to fuel manifold on base frame for easy installation of vessel’s hard piping. Lubrication System • 500 hour oil change interval when fuel and oil requirements are met. (375 hours on M1066H @ 60 Hz) • Positive displacement gear-type oil pump. • Full ow, spin-on oil lter. • Oil spray cooling reduces piston crown temperature for longer life. • Freshwater, plate-type, full ow oil cooler reduces heat and thermal breakdown of lube oil. • Large capacity oil pan. • Cast aluminum rocker arm cover traps valve noise and acts as a closed loop crank-case vent to keep oil vapor in the engine. • Lube oil drain for quick oil changes. Freshwater Cooling System • 2 thermostats for safety and quicker warm-ups. • Heat exchanger cooling includes: Gear driven, flexible impeller seawater pump. Easy to clean, tube-type heat exchanger is made of cupro-nickel for long life. • Cast iron, expansion tank with brass ller neck for easy lling. • Cast-iron exhaust manifold has double pass freshwater ow for even temperature control, fast warm-up and no hot spots. • Zinc anode electrolysis protection. • M1066T available in keel cooled configuration. Classification Standards • ABS Type approval on A1, A2, A3 and H models. Lloyd’s Register states that Northern Lights marine generator sets have been successfully tested in accordance with relevant requirements of Lloyd’s Register for Marine Generator applications. Superior PMG Generator Ends Northern Lights generator ends achieve ±0.5% voltage regulation. All have low temperature rise ratings that meet or exceed classification society requirements including ABS and Lloyds. All M1066’s have Permanent Magnet Generators for 300% short circuit capability required for classed vessels. Committed to Providing Complete Solutions Northern Lights generator sets are thoroughly factory tested and go through a complete quality control program to ensure your total satisfaction Our design philosophy allows us to provide comprehensive solutions to your power production needs. Because engine room space is always at a premium, Northern Lights offers Low-Profile generator sets that save valuable inches where you need it most. Our line of options and accessories are designed to integrate into a total power system specifically built for your vessel. PTO’s, sound enclosures and custom panels are among the options that make your power system as unique as your boat. Air System-Turbocharger-Aftercooler • Dry air lter cleans air and reduces air intake noise. • A1, A2, A3, H models have aftercooler with aircraft quality, 70/30 cupro-nickel, two pass element. Oval water tubes are easy to clean and stronger than round tubes. Corrugated air cooling fin design supports tubes better than plate fin type. Seawater piping is cast bronze and stainless steel. Water never touches the cast aluminum air ducts. No gaskets; all components are machined and have o-ring seals. Seawater direct from the pump for maximum cooling. Dry bolt holes protect cylinders. • Turbocharged to increase output. The turbocharger turbine housings are freshwater cooled for safety. • M1066H is US EPA Tier III certified. DC Electrical System and Electronic System Profiler • Standard, S-3B remote mount control panel with NEMA enclosure has engine hour meter, coolant temperature gauge, oil pressure gauge, DC voltage meter, start-stop switch and shutdown bypass switch. • Low oil pressure and high coolant temperature safety shutdowns. • Northern Lights ESP supplies SAE J1939 data stream through a CAN bus plug for optional engine monitor. • Negative ground, 12 volt DC system has circuit breaker, starter motor and battery charging alternator with regulator. • Reliable relay based DC system is easy to trouble shoot and repair. Each relay is inexpensive and simply plug-in. No expensive printed circuit board to fail. Relays make multi-panel installation up to 110 ft from set quick & easy. Engine and panel are pre-wired and have terminal strips. AC Generator • Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design. • Generators meet or exceed ABS standards and include class H insulation, accessible diodes, oversized ball bearings and marine grade shafts. Conservative heat rise rating of 95°/50° on T, A Series and 60 Hz H units. (Heat rise rating of 110o/45o on 50 Hz H units.) • Engines and generators are torsionally matched for long life. • Isochronous electronic governor for 0% AC frequency droop. • Automatic voltage regulator gives fast response to electrical load changes. Voltage is regulated to ±0.5% (one half of one percent) over the entire range from no load to full load. • All M1066 models have PMG (permanent magnet generator) to power the automatic voltage regulator for 300% short circuit capability needed by classed vessels. Special Equipment • Hydrolastic mounts isolate 98% of set vibration from hull. • Welded steel base frame with drip pan. Easy to clean. • Beltguard protects operator. • Sparkling white, IMRON® poly-urethane paint protects your set. • Operator’s and parts manuals. • Optional low profile sound enclosure for industry best attenuation in smaller package.
