Product catalog summary

Engine Specifications
The Baudouin 6M26.3 engine is designed for marine applications, featuring a common rail injection system. It has six inline cylinders with a bore and stroke of 150 mm each, resulting in a total displacement of 15.9 liters. The engine rotates counterclockwise and has an idle speed of 650 RPM. It is equipped with a 14-inch flywheel and an SAE 1 flywheel housing.

Performance and Fuel Consumption
The engine offers different power ratings and fuel consumption values depending on the duty cycle:

P1: 442 kW (601 HP) at 1800 RPM with fuel consumption of 200/201 g/kWh.
P2: 515 kW (700 HP) at 2000 RPM and 552 kW (751 HP) at 2100 RPM with fuel consumption ranging from 200 to 221 g/kWh.
P3: 599 kW (814 HP) at 2100 RPM with fuel consumption of 225/230 g/kWh.

Duty Applications
The engine is suitable for various marine applications:

P1 Continuous Duty: Deep sea trawlers, tug boats, freighters, ferries, etc.
P2 Heavy Duty: Similar applications as P1 with additional load capacity.
P3 Intermittent Duty: Seasonal passenger vessels, fishing boats, pilot boats, etc.
P4 Light Duty: Private pleasure boats, survey vessels, military fast vessels.
P5 High Performance Duty: High-speed private and multi-hull pleasure boats.

Engine Design and Features
The engine is engineered for durability and performance in demanding marine environments. It features individual cylinder heads for easy maintenance, high-efficiency turbochargers, and a two-stage cooling system. The lubrication system includes full-flow lube oil filters and a fresh water-cooled lube oil heat exchanger.

Fuel and Exhaust Systems
The engine uses a common-rail injection system with a high-pressure pump and shielded injection rail. It includes a double flow raw water-cooled intake air heat exchanger and a high-efficiency dry turbocharger.

Electrical and Optional Equipment
The electrical system operates at 24V DC with a 175A battery alternator. Optional equipment includes external fuel pre-filters, keel cooling, wet exhaust, and more.

Dimensions and Installation
The engine dimensions vary based on configuration, with the engine alone measuring 2102 mm in length. It supports adaptable configurations such as over-gearbox and stand-alone installations.

Environmental and Performance Standards
The engine complies with IMO III and EPA4 standards, ensuring efficient fuel consumption and reduced emissions. It operates effectively under various ambient conditions, with specific reference conditions outlined for optimal performance.
