Volvo Penta D4-300 300HP Marine Diesel Inboard

New Volvo Penta D4-300 300 HP Marine Diesel Inboard

Exceptional diesel performance for its size:

Volvo Penta’s 4-cylinder D4-300 is developed from the latest design in modern diesel technology. The engine has common rail fuel injection system, double overhead camshafts, 4 valves per cylinder, turbocharger and aftercooler. Together with a large swept volume and the EVC system (Electronic Vessel Control), this results in world-class diesel performance, combined with low emissions. The engine is extremely compact for its high output. 

World-class performance:

The common rail fuel injection system, controlled by EVC, in combination with a large swept volume, ensures outstanding torque during acceleration, with virtually no sign of smoke. This matched with the engine’s high load carrying capability creates a sporty feeling and power, when needed. 

Compact and robust:

The engine is extremely compact for its large swept volume and high output. With the rear end transmission, driving the high-pressure injection pump and the camshafts, a high degree of integrated systems, a high-efficiency after cooler, a marinization performed with very few hoses, and a fully symmetric engine, the package simply gets that compact. 

The rigid cast-iron cylinder block and head, combined ladder frame and balance shafts, and exactly controlled (up to three steps) fuel injection gives excellent onboard comfort with low noise and vibration levels.

EVC/EC – Plug and go:

EVC Electronic Vessel Control is the latest development in engine control and instrumentation for Volvo Penta marine engines. It offers a higher level of integration in your boat: electronic shift and throttle for smooth and safe control, a complete range of easy to read data link gauges, an EVC System Display (option) and much more, everything in just one CAN cable. EVC makes boating easier and safer with twin engine synchronization and new software functions such as Volvo Penta Low Speed (option), which signifi cantly reduces boat speed at idle to simplify maneuvering in tight quarters.

EVC is scalable from one station up to four, from a classic dashboard up to an advanced driver information system. EVC works closely together with the engine management system offering you constant power output regardless of temperature (5–55°C / 41–131°F) and quality of the fuel. The system is built on the latest automotive technology with waterproof connectors, so it’s just plug and go. 

A propulsion package fully matched, tested and supported by one company:

Volvo Penta’s hydraulically shifted re verse gear has been specially de vel oped with a view to increasing the stand ard of com fort on board. Matched with the characteristics of the D4 engine, the hy drau lic shifting mechanism and a gear tech nol o gy that uses bevel gears through out the gear train, we have developed a complete package for high torque, operational reliability and reduction of engine noise and vibrations. The combination of 8° down angle, large drop center and small dimensions provides for optimized installations. V-drives are also available. In order to get full benefi t of the EVC system the reverse gear is equipped with electric shifting valve.

Meeting new emission standards:

The common rail injection system in combination with electronics and an advanced combustion system are setting new standards in minimizing noxious emissions and particulates. The engine complies with IMO NOx limits and the comprehensive emission requirements EU RCD and US EPA Tier 2.
