Augsburg Marine Engines Delivered to Spain and China

Monday, October 14, 2002
MAN B&W Diesel Group has revised their 32/40 engine series based on a number of innovations, the engine’s soot concentration was reduced under the visibility limit almost over the whole load range. At the same time, the fuel consumption sank. The company has now received two orders for the delivery of six 32/40 engines in total. Two 9L32/40 large-bore Diesel engines with an output of just under 5900 HP each will, by the end of the year, be built for the German shipping company Bockstiegel, Emden, delivered to China and installed in two new 502-TEU container vessels in the Jingling shipyard, Nanjing. In spring 2003, MAN B&W Diesel will deliver the engine components for four 7L32/40 (approx. 4600 HP) to the Spanish licensee IZAR in Cartagena. The engines will propel a so-called Ro-Pax ferry, which will be in service between the Faroe Islands. The engines of the 32/40 type were presented in 1992/93. Since then 610 engines have been sold, 535 of them for vessel projects, the remaining 75 for power generation in Diesel power plants. 57 engines of the 32/40 series run in oil-drilling ships and other offshore vessels. The revision focused on the combustion chamber and its environment. An injection nozzle with smaller spray hole cross section and reduced blind end bore volume is used, which results in an increased injection pressure and avoids fuel dripping. This permits a better atomisation of the fuel and, therefore, improved combustion and reduced exhaust smoke. In addition, water-cooled injection nozzles reduce the exhaust soot of the engine, particularly if very poor fuel qualities are run. In the combustion chamber design, special attention was paid to smooth combustion chamber walls and small gap sizes. In addition, the new turbocharger has a special effect, which results in a considerable reduction of the soot values, above all in the mean load range.
