PROPULSION UPDATE M.A.N.-B&W Turbochargers Reduce Fuel Consumption —Literature Available Cross-section of an NA exhaust gas turbo- charger. This series covers the range up to a maximum engine output of 22,000 kw (29,920 hp) per turbocharger. During the past year, the Polish engine manufacturer ZGODA tested an NA 34/T M.A.N.-B&W high-effi- ciency turbocharger on the test bed of a 6 ZL 40 engine. After successful tests, an identical engine from the four-engine plant of the ferry Pom- erania was equipped with an NA 34T. Because of excellent results achieved during a 2,000-hour period of operation, the vessel's owner, Pol- ish Baltic Shipping Company, de- cided to equip the other three en- gines with M.A.N.-B&W turbo- chargers. Polish Baltic reports the following advantages with the new turbo- chargers: • A reduction in the rate of fuel consumption by 4.5-6.0 grams per kilowatt hour, depending on engine load. For each engine this results in fuel savings of up to $7,000 per year. • Following the installation of the improved turbocharging system, all engines may now be operated at full load without thermal overload. Con- sequently, the ferry can be operated at higher speeds during the busy season. • Technical improvements allow one or two main engines to be shut down sooner than was previously possible when operating at lower speeds during the slow season.
