VOLVO PENTA INBOARD DIESEL New standard for yacht comfort diesel features minimal vibrations, quiet and economical running thanks to a robust block with balance shafts and ladder frame and a low cruising rpm. A smooth-running engine with excellent low end torque for demanding maneu- vers, operated by electronic shift and Fully electronic world-class diesel performance, clean exhausts and low emissions achieved by common rail fuel injection, double overhead camshafts, and 4 valves per cylinder makes this en- gine the ideal choice for yacht comfort. D4-180 with HS45AE 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 for maneuverability, with virtually no sign of smoke. Matched with the low rated rpm, this makes the engine ideal for displacement The engine is extremely compact for its large swept volume. With the rear-end transmis- sion, 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-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 maneuver- ing with fingertip precision in any situation. Integrated pushbuttons give easy access to functions such as Low Speed, Cruise Con- trol and Single Lever Control, which allows for safe and easy boating. 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 environ- mental 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 increasing 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 optimized installations. V-drives and in-line reverse gears are also available. In order to get full benefit of the EVC sys- tem the reverse gear is equipped with elec- tric shifting valve. Meeting new emission standards The common rail injection system in com- bination with electronics and an advanced combustion system are setting new stan- dards in minimizing noxious emissions and particulates. The engine complies with IMO NOx limits and the comprehensive emission Crankshaft power --- Calculated propeller load exp. 3 hp, metric
