Engine Block • US EPA Tier III compliant. • Four cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavyduty industrial engine blocks. • Balanced, forged crankshaft with induction hardened journals and rolled fillets for long life. • Replaceable, wet cylinder liners for long life and low rebuild costs. • Bimetallic valves with chrome stems and 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. • A single poly-vee drive belt powers the alternator and jacket-water pump. Fuel System • High pressure common rail fuel injection for smooth, clean delivery. • Direct fuel injection system. • Ring clamp fuel lters with air bleed and drain. • Diaphragm-type, mechanical fuel transfer pump with manual priming lever. Lubrication System • Positive displacement gear-type oil pump. • Full ow, spin-on oil lter. • Oil spray cooling reduces piston crown temperature. • Jacket-water, plate-type, full ow oil cooler reduces heat and prevents lube oil breakdown. • Large capacity oil pan. • A closed loop crankcase vent traps oil vapor to keep the engine room clean. • Dry air lter silences intake noise. • Turbocharger with jacket water cooled turbine housing for safety. Cooling System • Heat exchanger with keel cooled option. • Gear driven sea water pump with self-priming flexible impeller. Bronze with stainless steel shaft. • Cast iron expansion tank. • Two thermostats for quick warm-ups and safety. • Cast-iron exhaust manifold for reliable temperature control. • Negative ground, 12 volt DC system has circuit breaker, starter motor and alternator with regulator. • Low oil pressure and high coolant temperature safety shutdowns. •Optional control panels help you specify the amount and type of information required. Comprehensive list of optional alarms and safety shutdowns. • Optional DC logic system for simplified maintenance. • Optional pre-wired engine, panel with terminal strips. • Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design. • All NL generators meet or exceed class society standards with Class “H” insulation, accessible diodes, oversized ball bearings, marine grade shafts and conservative 90°/50° heat rise ratings. • Engines and generators are torsionally matched for long life. • Automatic voltage regulator; ±0.5% regulation over the entire range from no load to full load. • Configured for 0% isochronous droop with integral electronic governor control supplied by ECU. Special Equipment • PMG option for 300% short circuit protection. • Welded steel base frame. • Sparkling white IMRON® polyurethane paint. • Operator’s and parts manuals. • Optional sound enclosure for industry best sound and vibration attenuation in a compact design.
