Baudouin 6M19.3 Electronic Commercial Marine Diesel Engine

Description

Fast offshore crew vessels rely on the Baudouin 6M19.3 Electronic Commercial Marine Diesel Engine to maintain rigorous offshore transport schedules. Displacing 11.6 liters (708 cu in), this common rail platform complies with IMO Tier II and EPA Marine Tier 3 emissions. Tight forward engine flat clearance complicates raw-water pump access, while high-mounted turbocharger ducting demands adequate overhead deckhead space.

Individual four-valve cast iron cylinder heads provide this Baudouin compact six cylinder diesel with outstanding thermal stability across high load factors. Replaceable wet sleeve liners allow efficient in-frame cylinder overhauls without removing the engine block from the vessel stringers. High-pressure common rail injection optimizes fuel atomization across variable speeds. An isolated 24V marine ground prevents electrolytic pitting on aluminum hulls. Bare dry mass registers at 1,200 kg (2,646 lbs) without transmission.

Key Features of Baudouin 6M19.3

Requesting a verified Baudouin 6M19.3 repower quote helps port engineers match existing engine bearers and shaft couplings. Electronic controls streamline helm integration across multiple steering stations.

• Bore and stroke measurements of 126 x 155 mm (4.96 x 6.10 in) create 11.6 L (708 cu in) of displacement.
• Delivers a continuous P1 commercial rating of 450 BHP (331 kW) at 1,800 RPM.
• Reaches maximum intermittent outputs of 578 BHP (425 kW) at 2,200 RPM for fast response.
• Serves as a high-efficiency commercial shaft propulsion engine for workboats and pilot cutters.
• A water-cooled charge air intercooler drops intake manifold air temperatures to boost combustion density.
• Standard SAE 1 flywheel housing with SAE 14 flywheel connects cleanly to commercial marine transmissions.
• Heavy structural mounting feet anchor the 1,200 kg (2,646 lbs) dry propulsion mass.

Fuel Burn and Thermal Limits

Electronic common rail fueling generates aggressive low-end torque, with the turbocharger establishing positive manifold pressure past 1,200 RPM to lift planing hulls onto step. Working this 550 hp commercial diesel near maximum intermittent rating consumes approximately 28.5 GPH (108 LPH). Wet exhaust gas temperatures must stay below 1,022°F (550°C) to safeguard turbine housing metallurgy. Ambient engine room temperatures above 122°F (50°C) trigger electronic fueling derates. Ensure adequate blower airflow. Multi-pulse injection prevents low-idle wet stacking during slow harbor patrol duty.

Machinery Space Servicing and Protection

Machinery flat ergonomics determine turnaround speed during crew boat turnarounds. Checking lube oil requires 380 mm (15.0 in) overhead clearance above valve covers to withdraw the dipstick cleanly. Closed crankcase breathers route blowby mist to intake air, preventing oily bilge film. Fuel filter servicing demands drip trays to catch diesel spills. Sacrificial zinc anodes on heat exchanger caps require bi-monthly checks to halt galvanic pitting. Anti-seize paste prevents seized pipe bolts.

• Inspect raw-water pump impellers seasonally for blade cracking.
• Evacuate the 30.0-liter oil sump using low-mounted manual drain valves.
• Maintain shaft coupling alignment within 0.05 mm across resilient mounts.
