June 2012 marinelink.com23plies the complete drive-line for ship propulsions from one source: engine ?transmission ? instruments. Coupling ?shaft and propeller are assembled fromchosen, strategic partners. With the on-board gensets the company delivers the engine and the chosen part- ners contributing frame and instrument panels 13- and 16-liter engines forpropulsion and auxiliaryScania?s engine range illustrates the essence of the thinking: maximum up-time, proven reliability and outstanding operating economy. All this in compact and powerful packages built on Scania?s modular product system, which simpli-fies servicing and parts management, and facilitates individual specifications as well as volume production. Power at the new in-line DI13 is available from 294 to 551 kW at speeds with 1,800 and 2,300rpm for main-drives and outputs from 323 to 426 kW with speeds at1.500/1,800 rpm for on-board gensets. SCANIA INTRODUCES ITS NEW DI16 MARINE DIESEL ENGINE The company showcased its new series of diesel engines for marine application,including the new DI16 series, at the Sea-work show in the UK. With the new DI 16 diesel engine, es- pecially developed for applications in workboats as well as in patrol boats and yachts,Scania is aiming to consoli-date its position in the marine market seg- ment.The turbocharged and aftercooled en- gine is available as 8-cylinder, in V-90 degrees configuration, only. With 130 mm bore and 154 mm stroke it features a displacement of 2.04 liters per cylinder. With the total displacement of 16.32 liters (a displacement increase of around5% compared to the former DI 16 marinedrive), the engine is capable of develop- ing an output of 735 kW (1,000 hp). With this power increase Robert Sobocki, Vice President Engines, says: ?we are now highly competitive with engines well above 16-litres.? Thetorque ratings of up to 3,340 Nm are par- ticularly high for this output class. This ensures ample performance even at low revolutions, while facilitating running at favorable revolutions in all conditions, in- cluding high sea and high load. Individ- ual cylinder heads with four valves per cylinder promotes repairability and fuel economy. The new DI 16 fulfills the emission standards IMO II, EU StageIIIA and US Tier 2, Scania said. The en- gine is equipped with a Scania developed Engine Management System, EMS, inorder to ensure the control of all aspectsrelated to engine performance. The in- jection system is based on electronicallycontrolled PDE unit injectors that gives low exhaust emissions with good fuel economy and a high torque already atlow revolutions. According to Scania: Vital for marine installations is that the engine is compact, has easy-to-fit auxil- iaries and is designed for easy servicing.Scania's V8 engines traditionally meet all of these requirements thanks to the com-pact vee-design, which reduces the over- all length. Ancillaries can be efficiently accommodated inside the footprint of theengine. Scania?s-Saver ring, placed at the top of each cylinder liner, reduces carbon deposits on the edge of the piston crown and reduces cylinder liner wear. In spite of higher performance andtighter emission levels, Scania has been able to raise maintenance and oil-changeintervals to 500 hours. MR June12 # 3 (17-24):MR Template 6/12/2012 8:51 AM Page 23
