Baudouin 4W105M Auxiliary Commercial Marine Diesel Engine

Description

Eliminate auxiliary electrical blackout risk using the Baudouin 4W105M Marine Auxiliary Engine, built for continuous duty generation on commercial barges, fishing tenders, and harbor pushboats. Delivering 90 kW mechanical drive power at 1800 RPM, this four-cylinder four-stroke diesel engine powers shipboard generator stators, hydraulic power packs, and fire pumps across continuous multi-week offshore voyages without thermal degradation.

A high-tensile cast-iron engine block houses a 4.5L displacement cylinder assembly featuring dry cylinder liners and individual four-valve cylinder heads. Dual-circuit water cooling circulates fluid through a cupronickel tube-and-shell heat exchanger driven by gear-driven raw water and freshwater pumps. Weighing 1433 lbs dry, this inboard marine powerplant occupies a machinery space envelope measuring 45.3 inches long by 31.5 inches wide by 38.6 inches high.

Key Features of Baudouin 4W105M

Fleet engineers who buy Baudouin 4W105M marine auxiliary engine units secure commercial vessel repower hardware engineered for mechanical longevity. The mechanical inline injection pump tolerates varying marine fuel lubricity while maintaining balanced fuel delivery across continuous commercial generator duty cycles.

• 90 kW continuous mechanical output drives prime marine generator alternators under maximum continuous electrical load.
• 1800 RPM mechanical governor speed stabilizes 60 Hz electrical output across sudden switchboard load additions.
• Mechanical inline injection pump tolerates variable fuel lubricity without electronic sensor communication faults.
• Individual cylinder heads simplify top-end overhauls inside tight commercial vessel machinery spaces.
• 4W105M commercial vessel repower hardware incorporates gear-driven seawater pumps to eliminate drive belt slip.
• Water-cooled exhaust manifold lowers engine compartment radiant temperatures to protect nearby wiring looms.
• Dual spin-on fuel filters permit clean fuel changes during non-stop vessel propulsion shifts.
• Automated mechanical shutdown levers protect the forged crankshaft from low oil pressure or high coolant heat.

Torque Rise Combustion Thermal Performance

Operating with low brake specific fuel consumption, this turbocharged engine provides prompt torque response to counteract sudden hydraulic motor starts and heavy electrical step loads. The mechanical governor clamps engine speed within a 3 percent droop curve, holding 1800 RPM steady under 50 kW load steps. Burning 3.1 GPH of diesel at 75 percent continuous load, the engine yields high thermal efficiency while maintaining exhaust backpressure well below 10 kPa limits.

Hull Bedding Propeller Shaft Clearances

Mount the engine base directly to structural steel hull stringers using fitted grade-eight marine foundation bolts. Maintain 18 inches of clearance around fuel injectors and oil filters for overhaul access. Connect the water-cooled exhaust flange to dry silencers or wet water-lift exhausts, incorporating flexible stainless bellows to isolate vibration from hull plates.

Engine Room Usability Scheduled Inspections

Dual oil fill ports and a reversible oil dipstick accommodate port or starboard engine room access walkways. This commercial engine is not engineered for light-duty pleasure craft hydroplane hulls, nor for installations lacking continuous sea chest raw water circulation.

• Inspect sea strainers and check lube oil dipstick levels before each shift.
• Change engine lubricating oil and install fresh spin-on oil filters every 250 runtime hours.
• Check valve lash clearances and test fuel injector crack pressure every 1500 runtime hours.

Marine Warranty Freight Crate Manifest

Baudouin protects this auxiliary engine with a 2-Year commercial continuous duty warranty covering the engine block, crankshaft, and cylinder heads. The shipping pallet delivers the Baudouin 4W105M engine, instrument gauge panel, wiring loom harness, spare oil filters, and comprehensive technical workshop manual.
