VOLVO PENTA AQUAMATIC DUOPROP

D6-280/DP

206 kW (280 hp) crankshaft power acc. to ISO 8665

Performance for marine use

Volvo Penta’s new 6-cylinder D6-280 is developed from the latest design in modern diesel technology. The engine has com- mon 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 Con- trol), this results in world-class diesel performance, combined with low emissions.

World-class performance The common rail fuel injection system, con- trolled by EVC, in combination with a large swept volume, ensures outstanding torque during the 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.

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 tem- perature (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.

Compact and robust The engine is lightweight and extremely compact for its large swept volume and high output. With the rear-end transmission, driv- ing the high-pressure injection pump and the camshafts, a high degree of integrated sys- tems, a high-efficiency aftercooler, a mariniza- tion performed with very few hoses, and a fully symmetric engine, the package simply gets that compact.

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

The new Duoprop drive The new corrosion-resistant aluminum drive is based on the experience with the well-proven original DP drive, and fully matched to the very powerful engine. The modern styling, the hydrodynamic design for low drag, and the Duoprop high strength bronze propellers, spe- cially delevoped for the drive, make the package complete. This results in unbeatable boat char- acteristics in terms of acceleration, top speed, and drivability.

The drive comes equipped with fully hydraulic further developed X-act steering. It features inte- grated external steering cylinders, controlled by an exact feedback valve as standard.

EVC/EC – Plug and go EVC Electronic Vessel Control is the latest development in engine control and instru- mentation for Volvo Penta marine engines. It offers a higher level of integration in your boat: electrical shift and throttle for smooth and safe control, new power trim control, a complete new range of easy to read, data link gauges, a large LCD display (option) and much more, everything in just one CAN cable.

The integrated exhaust system and seawater in- take, a hallmark for Volvo Penta, are also standard.

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 particles. The engine will meet future comprehensive emission require- ments to be introduced in Europe and the US in 2006.

EVC makes boating easier and safer, offer- ing twin engine and power trim synchroniza- tion and adjustable power trim limits. EVC is scalable from one station up to four, from

The new DP drive has been designed to lead exhaust gases into the propeller path, to avoid the “station wagon effect” and keep noise levels at a minimum.
