the standard 3500 Series B engines, pro- viding more displacement, therefore generating more power. Power is reportedly increased by up to 13 per- cent, giving the new 3516B a continu- ous rating of 2,260 bhp and a top com- mercial rating of 2,500 bhp at 1,600 rpm. In addition, the engine also saves on fuel, with a reported seven percent improvement in power to weight ratios and a seven percent improvement in fuel economy. Displacement is increased through component changes to the crankshaft, connecting rods and pistons that length- en engine stroke by 25.4 mm (1 in.) from 190 mm to 215 mm (7.5 to 8.5 in.). This adds more than a half a liter per cylinder, giving the new 3516B engine 78.1 liters (4,763 cu. in.) of displace- ment. Turbochargers and aftercoolers use the same technology proven in 3500 Series B engines, but capacities are increased. Circle 66 on Reader Service Card New Marine Diesel Jointly Produced The Austria-based engine manufactur- er Steyr-Daimler-Puch Motorentechnik has launched two new lightweight marine high speed diesels, to be distrib- uted by the Danish Company Aabenraa Motorfabrik. The new brand name is Bukh+Steyr Solas and the two new engines are approved according to Solas/IMO. The following are technical details of the two new units: They are designed for high reliability and efficiency, feature high-pressure unit injectors (up to 2,000 bar); a monoblock design without cylinder head gasket; and noise encapsulation. While application parameters are varied, the engines are said to be particularly suited for fast rescue boat, RIB, patrol boat, firefighting vessel and special mis- sion boat applications.
