Baudouin 6M19.3 Electronic Commercial Marine Diesel Engine

Description

Cut fuel consumption across commercial workboat operations while maintaining full EPA Marine Tier 3 emissions compliance. The Baudouin 6M19.3 Commercial Marine Engine generates 450 BHP continuous power from an 11.6-liter electronic inline-six platform. Common rail fuel injection components require ultra-clean fuel supplies, demanding dual spin-on water separators to prevent high-pressure pump damage.

High-grade cast iron forms the rigid inline-six engine block and individual four-valve cylinder heads. Replaceable wet sleeve cast iron liners provide excellent heat dissipation and simplify in-hull engine overhauls. An isolated-ground 24V electrical system includes a 6.0 kW starter and 70A marine alternator. Dry engine mass equals 2,646 lbs, requiring engine room mounting space of 74.2in length, 38.2in width, and 46.5in height with an SAE 1 flywheel housing.

Key Features of Baudouin 6M19.3

Commercial harbor operators buy Baudouin 6M19.3 engines to power pilot boats and crew transfer vessels with clean electronic injection. Fleet pricing gives commercial marine operators an economical propulsion package that balances high torque output with low fuel consumption.

• High-Pressure Common Rail injection operates up to 23,200 PSI to minimize exhaust soot.
• Continuous P1 rating outputs 450 BHP at 1,800 RPM for heavy continuous workboat duty.
• Intermittent P3 rating yields 578 BHP at 2,200 RPM for fast crew transfer runs.
• Four-valve cylinder heads optimize air intake velocity and combustion chamber swirl.
• Cupronickel tube heat exchanger resists corrosive seawater damage in coastal operation.
• Wet sleeve cylinder liners allow rapid in-hull overhauls without removing the engine block.
• Standard SAE 1 flywheel housing connects to ZF, Dong-I, or Twin Disc marine transmissions.

Electronic Common Rail Bench Testing

Dynamometer test cell evaluations document 450 BHP continuous output at 1,800 RPM with fuel burn averaging 0.340 lbs per horsepower hour. Crankshaft main journal runout measures 0.0003in TIR across induction-hardened bearing surfaces. Intake manifold boost pressure reaches 32 PSI under maximum continuous load. Closed circuit coolant temperatures stabilize at 176°F under full water brake loading. Engine room acoustic sensors measure 94 dB at 3ft distance during peak continuous torque output of 1,313 ft-lbs.

Engine Room Usability Service Schedule

The electronic control system communicates through standard J1939 CAN-bus networks, feeding real-time fuel rate and boost pressure data to helm displays. Do not install this electronic common-rail engine in workboats lacking primary 2-micron fuel water separator filtration systems.

• Replace 2-micron primary fuel filter cartridges and drain water bowls every 250 hours.
• Change the 7.92-gallon lube oil sump and spin-on filters every 500 operating hours.
• Check cupronickel heat exchanger sacrificial zinc anodes for metal loss every 90 days.
