M944T3

Product catalog summary

Engine Block
The M944T3 features a four-cycle, 4-cylinder, dry turbocharged, overhead valve diesel engine. It includes an induction hardened crankshaft made of forged carbon steel, which is stronger than cast iron. The timing and PTO gears are helical cut and ground from carbon steel to reduce noise, and it has a cross-flow head for efficient breathing.

Cooling System
The engine uses a freshwater cooling system available in heat exchanger or keel cooled configurations. The exhaust manifold is a large, easy-fill single-piece that is freshwater cooled for safety, reducing the need for hot, dry risers and minimizing hoses and gaskets. It is made of cast iron to resist corrosion and electrolysis, with zinc anode protection. The standard heat exchanger is a cupro-nickel tube-type with removable ends for easy cleaning, and the seawater pump is gear-driven, made of bronze and stainless steel.

Fuel System
The fuel system includes direct injection with glow plugs, a Bosch-type in-line injection pump with a 5% mechanical governor for close AC frequency control, pintle injectors, and a mechanical lift pump with a hand primer. It features a large spin-on fuel filter and flexible fuel lines routed to the base. The stop solenoid controls the fuel rack to eliminate speed variances and linkage problems.

Intake and Exhaust
The system meets US EPA Tier III emission standards and includes a dry turbocharger. A washable air cleaner in the cast intake manifold reduces intake noise, and a cast iron, wet exhaust elbow is included for safety.

Lubrication System
The lubrication system features a full-flow, spin-on oil filter with bypass, a 10.5 qt (10.0 ltr) center well oil pan with 250-hour oil change intervals, and an oil drain for quick, clean oil changes.

DC Electrical System
The DC system uses reliable relays instead of an unrepairable printed circuit board. It includes a 12-volt starter motor and battery charging alternator with a regulator and belt guard. The standard panel is remote mountable and includes an hour meter, stop-start switch with run light, preheat switch, and gauges for oil pressure, coolant temperature, and DC voltage. Safety shutdowns are included for low oil pressure, high coolant temperature, and high exhaust temperature.

AC Generator
The Northern Lights direct-coupled, brushless AC generator is maintenance-free, with a 12-wire 50 or 60 Hz output standard. It features an automatic voltage regulator powered by a dedicated AC winding for true 300% short circuit capability and circuit breaker protection, with quick ±1% RMS no-load to full-load voltage regulation.

Special Equipment
The unit includes a welded steel base frame with a drip pan, four platform mounts to isolate vibration, a belt guard for operator protection, and is painted with white, long-life polyurethane paint. Operator’s and parts manuals are standard.

Classification Standards
For classification standards, consult the factory for details.

Dimensions and Weight
The overall dimensions are 60.0 x 29.0 x 30.5 inches (1524 x 736 x 775 mm), with a sound enclosure weight of 140 lbs (64 kg). The approximate dry weight is 1416 lbs (642 kg).

AC Output
The generator provides 40 kW at 60 Hz, 1800 RPM, with a voltage regulation of ±1%.

Engine Specifications
The Lugger L944 engine is a vertical inline 4-cylinder diesel with a displacement of 203 in3 (3.3 ltr), bore/stroke of 3.70/4.72 in (94/120 mm), and turbocharged aspiration. It delivers 60.0 HP at 1800 RPM and 50.0 HP at 1500 RPM. Fuel consumption varies with load and RPM.
