M65T13L: 65 kW @ 1800 rpm

Engine Block
• US EPA Tier III compliant.
• Four cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavy-duty 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 filters with air bleed and drain.
• Diaphragm-type, mechanical fuel transfer pump with manual priming lever.
Lubrication System
• Positive displacement gear-type oil pump.
• Full flow, spin-on oil filter.
• Oil spray cooling reduces piston crown temperature.
• Jacket-water, plate-type, full flow 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.
Air System
• Dry air filter 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.
ESP and DC Electrical System
• 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.
AC Generator
• 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.
