NL944D3 Features and Benefits Engine Block • Lugger four cycle, 4 cylinder, liquid cooled, naturally aspirated, overhead valve industrial duty diesel engine block. • 2 valves per cylinder. • Double wall oil pan. • Crankshaft is induction hardened, forged carbon steel; stronger than cast iron. • Helical cut and ground carbon steel timing gears reduce noise. DC Electrical System • 12 volt starter and battery charging alternator with regulator. • DC system uses reliable relays instead of unrepairable printed circuit boards. • Standard panel: unit mounted S-1B has hour meter, shutdown bypass, stopstart switch and preheat switch. • Expandable to six panels, 110 ft from set. • Low oil pressure, high coolant temp shutdowns are standard. • Cross flow head for efficient breathing. • Liquid cooled with radiator and pusher cooling fan. Radiator shroud and fan hand guard. • Direct coupled, 4-pole, revolving field generator with Class H insulation and pre-lubricated, double sealed bearing. Brushless design is maintenance free. 12 lead-3 phase standard. Cooling System Fuel System • Indirect Injection with glow plugs. • Bosch-type in-line injection pump with 5% mechanical governor for close AC output frequency control. • Pintle type injectors. • Conservative heat rise rating of 95°F / 50°C, ideal for tropical applications and continuous operation. • Automatic Voltage Regulator (AVR) gives quick +/-1% RMS no load to full load voltage regulation. • High air flow from cast aluminum fan keeps generator running cool. • Terminal strip in j-box for easy voltage changes and connection to AC distribution system. • Mechanical fuel lift pump with hand primer. • Large spin-on fuel filter. Special Equipment • Flexible fuel lines routed to base. • Steel base frame provides rigid support and makes installation easy. • Stop solenoid controls fuel rack, not throttle, for fast engine shutdowns. • Vibration mounts isolate engine vibration for smooth, quiet operation. • Meets US EPA interim Tier IV emission requirements. • Large air cleaner with replaceable filter element.
