Features + Benefits

.Four cylinder, four cycle, in-line, liquid cooled, overhead valve, marine diesels based on heavy-duty engine blocks. Balanced, forged crankshaft with induction hardened journals and rolled fillets. 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. Dual gear-driven, counter-rotating balancing shafts for smooth operation. A single poly-vee drive belt powers the alternator and jacket-water pump.

Keel cooled with heat exchanger optional. Cast expansion tank. Two thermostats for quick warm-ups and safety. Cast-iron exhaust manifold for reliable temperature control.

High pressure common rail fuel injection for smooth, clean delivery. Direct fuel injection system. Ring clamp fuel filters with air bleed and drain. Electric fuel pump integrated into primary fuel filter. Computer controlled priming for ease of operation.

Dry air filter silences intake noise. Turbocharger with jacket water cooled turbine housings for safety.

Positive displacement gear-type oil pump. Full flow, spin-on oil fi lter. Oil spray cooling reduces piston crown temperature for longer life. Jacket-water, plate-type, full flow oil cooler reduces heat and prevents lube oil breakdown. Large capacity oil pan. Closed loop crankcase vent traps oil vapor to keep the engine room clean.

Negative ground, 12 volt DC system includes starter motor and alternator with regulator. Low oil pressure and high coolant temperature safety shutdown system. 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 110°/50° heat rise ratings. .Engines and generators are torsionally matched for long life. Automatic voltage regulator; ±1% regulation over the entire range from no load to full load. Configured for isochronous frequency control with ECU electronic governor control.
