18 MARITIME REPORTER & ENGINEERING NEWS ? JANUARY 2013 Building on Scania?s new global engine platform is the 16-liter marine V8, de- livering up to 1,000 hp and 2,460 Ib./ft. for patrol craft applica-tions, a compact power source that leverages technology and architecture with Scania?s truck and bus engines. ?The new 16 liter engine has gone up in horsepower for each duty cycle we offer, which means that we can ap- proach larger vessels,? said Mikael Lindner, President, Scania U.S.A. Inc. ?It also means is that this engine is now able to compete with a 18-24 liter engines, which is a huge benefit because you can get a smaller engine, that is lighter with great power, and better fuel consumption.?Central to the Scania line and this powerplant in particular is adher- ence to high power-to-weight ratio, a critical factor in the marine market for easy installation, refit and perfor- mance. ?One of the criteria?s when developing the new 16 was that it should be easily interchangeable with the current 16,? said Lindner. ?When you re-power the predecessor, it?s plug and play.? The official North American launch was in New Orleans early last month, where the company showcased its new 16 and 13-liter engines, as well as the enhanced instrumentation.Besides the new 16-liter V8, Sca- nia?s marine engine range includes a 13-liter inline six-cylinder unit launched in 2011, an engine intended for propulsion and auxiliary use.Each engine in the new range is designed for higher strength and du-rability, and many components are shared across the range, significantly reducing the number of unique parts per engine and assisting in the repair and maintenance of the unit. ?We use a modular design on the 13 liter and 16 liter engines, which have the same cylinder head, the same combustion chamber and the same lin-ers. Scania develops a single cylinder engine with one combustion chamber, and then adds cylinders as needed?Scania has a history of conducting basic engine development and manu-facturing, as well as the development of engine management, fuel injec-tion and emission control systems in-house, a strategy it sees as central to its goals in fuel economy, environ- mental performance and robustness.16-LITER V8S FROM 550 TO 1,000 HP The output of the new 16-liter ma-rine engines spans from 550 hp for continuous use to 1,000 hp for patrol craft use. The ratings have been uprat- ed for planing and displacement ves-sels, and the company?s engines are competitive with engines above the 16-liter threshold. Of particular note is the torque rating of up to 2,463.5 lb./ft., a high number for this output class. Engine rooms, particularly on smaller vessels, are generally ?space challenged,? and Scania sees to it that its engines produce high power from compact packages, enabling quick refit and easy servicing while main-TECHNICAL FEATURE PROPULSIONScania Unveils the Future 1,000 hp V8 Engine Launched in New OrleansEngine DimensionsEngine type Swept volume Length Width Height 13-liter inline 6 12.7 liters 59.0 in 37.6 in 42.2 in 16-liter V8 16.4 liters 61.0 in 49.2 in 47.8 in Dry weights 13-liter inline 6 16-liter V8 With heat exchanger 2,623.5 lbs 3,681.7 lbsWith keel cooling 2,513.3 Ibs 3,527.4 lbsEngine performance 13-liter inline 6 16-liter V8 Power 400-750 hp 550-1,000 hp 294-551 kW 405-736 kWTorque 1,365-2,165 lb/ft 1,760-2,465 lb/ftTHE NEW 16-LITER V8S ...
