VOLVO PENTA INBOARD DIESEL Exceptional diesel developed from the latest design in modern diesel technology. The engine has common rail fuel injec- tion system, double overhead cam- shafts, 4 valves per cylinder, turbo- charger and aftercooler. Together with a large swept volume and the EVC system (Electronic Vessel Control), this results in world-class diesel performance, combined with tremely compact for its high output. D4-300 with HS63AE reverse gear World-class performance The common rail fuel injection system, con- trolled 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 feel- ing and power, when needed. 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 de- gree of integrated systems, a high-efficiency aftercooler, 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-D, a new generation of the proven Elec- tronic Vessel Control offers the best driver experience available! The new economically designed controls engage smoothly and allow for maneuvering with fingertip precision in any situation. Inte- grated pushbuttons give easy access to func- tions such as Low Speed, Cruise Control and Single Lever Control, which allows for safe Complete the helm with your choice from the full range of easy to read gauges and displays including the new 7" color display. Add the trip computer function for accurate fuel management and minimized environmental impact. Engine synchronisation is of course standard in twin installations. A propulsion package fully matched, tested and supported by Volvo Penta's hydraulically shifted reverse gear has been specially developed with a view to in- creasing the standard of comfort on board. Matched with the characteristics of the D4 engine, the hydraulic shifting mechanism and a gear technology that uses bevel gears throughout the gear train, we have developed a complete package for high torque, opera- tional reliability and reduction of engine noise The combination of 8° down angle, large drop center and small dimensions provides for opti- mized installations. V-drives are also available. In order to get full benefit of the EVC sys- tem the reverse gear is equipped with electric shifting valve. Meeting new emission standards The common rail injection system in combina- tion with electronics and an advanced com- bustion system are setting new standards in minimizing noxious emissions and particulates. The engine complies with IMO NOx limits and the comprehensive emission require- - Crankshaft power kW -----------Calculated propeller load exp. 2.5 hp, metric Fuel consumption Liters/h At calculated propellerload exp. 2.5 us gal/h
