Volvo Penta D11-625 Marine Diesel Engine

Volvo Penta D11-625 Marine Diesel Engine

The Volvo Penta D11-625 is an in-line, 6-cylinder, 10.8-liter marine diesel engine equipped with common-rail fuel injection, overhead camshaft, and a twin-entry turbocharger with a water-cooled exhaust manifold. This advanced configuration delivers excellent operating economy, world-class performance, and reduced emissions.

The engine is built with a rigid cast-iron cylinder block and cylinder head, ensuring exceptional strength, reliability, and long-lasting durability, even in the most demanding marine environments.

Volvo Penta’s signature marine torque provides:

• Rapid acceleration and strong low-end power

• High load-carrying capability

• Consistent cruising speeds regardless of sea conditions

This ensures smooth handling and responsive performance in maneuvering and open-water operation.

The advanced high-pressure common-rail fuel injection system enhances combustion efficiency. The electronic control unit continuously optimizes fuel delivery, resulting in lower fuel consumption and improved operating cost efficiency.

With a large displacement and electronic engine management system, the D11-625 delivers:

• Smooth engine operation

• High power output

• Reduced emissions

• Excellent acceleration and cruising efficiency

Volvo Penta offers two certified onboard control systems:

• Electronic Vessel Control (EVC): Fully integrates engine and electronic systems, enabling features like single-lever control, cruise control, and advanced monitoring displays.

• Marine Commercial Control System (MCCS): An open system designed for seamless integration into vessel-wide control systems.

Volvo Penta propulsion systems are designed for simplified maintenance and long-term durability. Use of genuine oils, lubricants, and coolants ensures sustained performance. A fuel pre-filter accessory helps maintain engine cleanliness and reliability.
