Product catalog summary

Overview: The Baudouin 12M26.3 is a marine propulsion engine designed for various marine applications, offering durability, performance, and reliability. It features a V12 cylinder configuration with a bore and stroke of 150 mm each, and a total displacement of 31.8 liters. The engine rotates counterclockwise and has an idle speed of 650 RPM.

Specifications: The engine is equipped with a two-stage cooling system, a common-rail electronic fuel injection system, and a high-efficiency dry turbocharger. It operates on a 24V DC electrical system and includes optional equipment such as an external fuel pre-filter and keel cooling.

Performance Ratings: The engine is available in different duty ratings: P1 (Continuous Duty) with 883 kW at 1800 RPM, P2 (Heavy Duty) with up to 1104 kW at 2200 RPM, and P3 (Intermittent Duty) with 1214 kW at 2300 RPM. Fuel consumption varies with duty and is optimized for IMO III and EPA 4 standards.

Applications: The engine is suitable for a range of vessels including deep sea trawlers, tug boats, ferries, and pleasure boats. It supports continuous, heavy, intermittent, light, and high-performance duties.

Dimensions and Weight: The engine alone measures 2501 mm in length and weighs 3350 kg. Configurations with additional systems like SCR or Stage V vary in dimensions and weight.

Environmental and Operational Conditions: The engine is designed to operate efficiently under ambient temperatures up to 45°C and raw water temperatures up to 32°C, with a fuel oil relative density of 0.840 ± 0.005.

Key Features: Baudouin engines are engineered for easy maintenance with individual cylinder heads and are built with durable materials to ensure long-term reliability. The engines comply with ISO 3046-1:2002 standards and classification societies' maximum temperature definitions without power derating.
