Product catalog summary

Engine Specifications
The Baudouin 6W105M is a mechanical injection diesel engine designed for marine applications. It features 6 cylinders with a bore and stroke of 105 x 130 mm, resulting in a total displacement of 6.7 liters. The engine rotates counterclockwise and has an idle speed of 650 RPM. It is equipped with an SAE 3 flywheel and an SAE 11.5" flywheel housing.

Power and Duty Ratings
The engine is rated for various duty cycles:

P1 Continuous Duty: Suitable for deep sea trawlers, tug boats, and ferries, with an unrestricted application and an engine load factor of 80-100%.
P2 Heavy Duty: Similar applications as P1 but with a load factor of 30-80%.
P3 Intermittent Duty: For seasonal passenger vessels and fishing boats, with a load factor of 50%.
P4 Light Duty: For private pleasure boats and fast vessels.
P5 High Performance Duty: For high-performance private pleasure boats.

The engine's rated power varies with duty cycles, with P2 at 136 kW at 2100 RPM and P3 at 168 kW at 2425 RPM.

Design and Maintenance
Baudouin engines are engineered for durability and performance in marine environments. They feature individual cylinder heads for easy maintenance and are constructed with durable materials for long-term reliability.

Cooling and Lubrication Systems
The engine includes an integrated fresh water expansion tank, a gear-driven centrifugal raw water pump, and a high-efficiency tubular heat exchanger. The lubrication system features full-flow lube oil filters and a fresh water-cooled lube oil heat exchanger.

Fuel and Air Systems
The fuel system is mechanical injection with a duplex type fuel oil filter and an external fuel pre-filter with a water separator. The intake air and exhaust system includes a dry single-stage turbocharger.

Electrical System
The engine operates on a 24V DC insulated electrical system with an electrical starter and a 55A battery charger.

Optional and Standard Equipment
Optional equipment includes keel cooling configuration, wet exhaust, and elastic pads. Standard equipment encompasses the mechanical injection diesel engine with specified dimensions and dry weight.

Environmental and Performance Conditions
Reference conditions include an ambient temperature of 25°C, barometric pressure of 100 kPa, and relative humidity of 30%. The engine's performance is compliant with ISO 3046-1:2002 standards, with specific power definitions and consumption tolerances.

Performance Graphs
The document includes graphs illustrating torque, power, BSFC (Brake Specific Fuel Consumption), and fuel consumption across various RPMs, highlighting the engine's performance under full load conditions.
