Diesel Power Review Colt Industries (continued from page 15) With improved fuel economy and the ability to burn some of the poorest quality heavy fuels, these two Colt-Pielstick engines will be valuable assets to the marine industry. Fairbanks Morse Engine Divi- sion continues to offer the Colt- Pielstick PC2.5V and the Fair- banks Morse opposed piston diesel engines. These two engines have been widely used by the maritime industry for many years. Four each of these two engines provide propulsion power and electric power for the U.S. Navy's LSD-41 Whid- bey Island launched during June of 1983, with engines for LSD-42, 43, and 44 on order. The Colt-Pielstick PC2, 2.3, and 2.5V engines are rated between 6,000 hp and 11,700 hp. Colt-Piel- stick engine operation is readily adaptable to remote control and automatic monitoring. Fairbanks Morse engineers have designed systems meeting ASCG and ABS 1976 rules (ACCU requirements) for a "no-man" engine room watch. All Colt-Pielstick engines enjoy parts availability in major ports all over the world. The Fairbanks Morse 38D8-1/8 series opposed piston diesel en- gines are available with ratings from 708 hp to 4,200 hp with both blower scavenged and turbo- charged models. The two-cycle op- posed piston configuration pro- vides an improved power to weight ratio and reduced space require- ments. It also results in fewer moving parts for increased relia- bility. This engine has been used in marine propulsion and power generation applications since the mid 1930s. In addition to the U.S. Navy's Whidbey Island class LSDs, Fair- banks Morse opposed piston diesel engines provide power for second- ary propulsion systems and emer- gency power for U.S. Navy sub- marines. CUMMINS Write 47 on Reader Service Card Cummins Engine Company of Columbus, Ind., manufactures six series of marine propulsion en- gines. Designed for heavy-duty workboat and fishboat applica- tions, the Cummins engines are rated at 170 to 1,250 hp (127 to 932 kw) for continuous, 24-hour- per-day propulsion service. Sev- eral reverse and reduction gears are available for each model. The compact V series diesel en- gines are V8 configuration with "oversquare" cylinders in which the bore diameter is larger than the stroke. By allowing faster rpm without increasing internal stresses, an "oversquare" engine combines high horsepower, com- pact size, and light weight. The V-504-M is a naturally aspirated engine with a 504-cubic-inch (8.3 litre) displacement and is rated at 170 continuous hp at 2,800 rpm. The 555 series engines have a 555 cubic inch (9.1 litre) displacement and are naturally aspirated when rated for continuous duty at 185 hp at 2,800 rpm. The V/VT/VTA-903 series ma- rine diesels have the "oversquare" cylinder design and range in horsepower from 255 to 320, con- tinuous duty. Today's 903 engines have proven their reliability and economy in over 40,000 marine and industrial applications. The V-903-M is naturally aspirated rated at 255 hp, the VT-903-M is turbocharged rated at 285 hp, and the VTA-903-M is both turbo- charged and aftercooled rated at 320 hp. All are rated for continu- ous operation at 2,300 rpm and have a 903 cubic inch displace- ment (14.8 litres). The Cummins N/NT/NTA-855- M series engines are Cummins' most proven marine diesel. For 50 years the 855 series and its prede- cessors, the 672 and 743 series, have been the standard for com- parison of performance and econ- omy in marine and other heavy- duty applications. These engines are six-cylinder in-line diesels with ' Operating on Bunkgrfuel 4500 sRI/10b°F with main & auxiliary engines Cut your fuel costs, use MaK THE RELIABLE ENGINE ON BOARD <§>Krupp MaK Diesel Inc. 4333 DiPaulo Center • Glenview, IL 60025 Phone: 312-298-9544 • Telex: 254 252 kmdi glvw 16 Write 479 on Reader Service Card Maritime Reporter/Engineering News
