The new V12-1800 MAN Nutzfahrzeuge presents a genuine power package of a top performing diesel in its engine range generating a maximum torque of 6020 Nm even at 1200 rpm and accelerating at an impressive pace. The 12-cylinder brings yachts into the planing phase fast, achieving high speeds in next to no time. Common Rail direct injection enables fuel injection at very high pressure, producing optimally smooth running and the pleasant ride comfort of this V12. Two-stage turbocharging also features in the engine's technology. Compactly scaled at 2087 x 1153 x 1275 mm (L x W x H without gearbox), the V12-1800 leaves designers plenty of freedom and flexibility when planning their yachts. Weight is another advantage, in relation to performance the 12-cylinder at just 2365 kg weighs in at 1.31 kg per unit of horsepower. To achieve features like these, MAN's engineers further developed the V-series throughout, optimising engine components in the process. Cooling of the new V12 is by a plate heat exchanger, which allows flexible configuration of the cooling system. In addition to this the V12 comes with a space-saving and low-weight SAE1 flywheel housing. An advantage for engine installation by a boat builder is the modified exhaust system with a central gas outlet. All parts needing maintenance such as fuel and oil filters are arranged for ease of access. And the water pump is driven by a gear instead of a belt. Turning to the engine proper, here too the designers have made interesting modifications. The V12-1800 generates a constant 1800 hp (1324 kW) between 2100 and 2350 rpm. The use of extremely high-strength materials, such as steel pistons, permits gas pressures up to 240 bar and ignition pressures up to 1600 bar. Here a bedplate concept is implemented in a yacht engine for the first time to create the extra strength. This bedplate replaces the single bearing caps of the crankshaft, and plays a major part in reinforcing the crank case and minimising noise emission. Second-generation Common Rail injection plus an optimally conceived combustion process mean high performance together with exemplary emission figures. The V12-1800 naturally complies with current international exhaust directives. November 11, 2008
