Volvo Penta D4-230 Marine Engine

The Volvo Penta D4-230 marine engine is a compact and high-performance diesel propulsion solution designed for leisure and commercial vessels requiring strong acceleration, reliability, and fuel efficiency. Built on Volvo Penta’s advanced 4-liter engine platform, the D4-230 delivers 230 horsepower (169 kW) from a 3.7-liter inline four-cylinder configuration, combining lightweight construction with impressive torque characteristics for responsive handling and smooth cruising across varying sea conditions.

Equipped with high-pressure common-rail fuel injection and turbocharging with charge-air cooling, the engine achieves optimized combustion efficiency, reduced fuel consumption, and low emissions compliance with major international marine standards. The engine’s strong low-RPM torque enables faster planing, improved maneuverability, and consistent performance even under heavy loads, making it suitable for patrol boats, workboats, and recreational craft alike.

A key advantage of the D4-230 is its integration with Volvo Penta’s Electronic Vessel Control (EVC) system, which allows seamless communication between engine, transmission, and onboard electronics. This integration supports advanced features such as joystick docking, digital displays, and intelligent monitoring systems that enhance operator control, safety, and overall vessel efficiency.

The engine is engineered for durability and simplified maintenance, incorporating robust materials, efficient cooling systems, replaceable full-flow and bypass oil filters, and sensor-based monitoring for oil level and temperature. Long service intervals and easy access to maintenance points help reduce downtime and operating costs while maintaining peak performance throughout the engine’s lifespan.

With its combination of compact size, high torque output, advanced electronic control, and proven marine reliability, the Volvo Penta D4-230 is an excellent propulsion choice for modern vessels demanding dependable power, efficiency, and maneuverability.
