that the sfc of the 9-cylinder 9L58/ 64 engine will be 121 g/bhph. The 3-cylinder test engine was operated from the very beginning on fuel with a viscosity of 7,000 sec Redwood 1/100 F. In addition to high operating ef- ficiency, the 58/64 engines will provide excellent waste heat re- covery opportunities. Exhaust gas temperature downstream of the turbocharger will be 660 F over a broad operating range. In a num- ber of applications, this means that the at-sea electrical load can be produced by the waste heat re- covery system instead of an auxil- iary generator, resulting in addi- tional fuel savings.

M.A.N.-B&W HOLEBY Circle 28 on Reader Service Card M.A.N.-B&W Holeby in Den- mark manufactures heavy fuel oil marine generator sets with out- puts from 500 to 4,000 kw per unit at 720-750 rpm. As a member of the M.A.N.-B&W group of compa- nies, Holeby's gensets are based upon 80 years of experience in die- sel engine design, 70 years of ex- perience in marine genset design, and 45 years of experience in gen- set operation on heavy fuel oil. Holeby has extensive experience and continuing research and de- velopment in the diesel field. It manufactures four-stroke engines with power outputs from 450 to 5,500 bhp. In addition to diesel engines, Holeby production includes spare parts and components such as crankshafts and connecting rods for the manufacture of M.A.N.- B&W diesels by licensees. It also manufactures fuel oil mixing units and other auxiliary equipment. As a result of recent develop- ment projects, all types of Holeby engines can now be supplied in uprated four-valve versions that operate efficiently on the same heavy fuel oil used in the main propulsion engines. Holeby has termed this its Uni-Fuel Concept, which features simplified fuel oil system, simplified and cheaper bunkering, and the ability to op- erate on fuels up to 7,000 sec Red- wood 1 at 100 F. MIRRLEES BLACKSTONE Circle 29 on Reader Service Card Mirrlees Blackstone, the British diesel engine manufacturer that is a wholly owned subsidiary of the Hawker Siddeley Group, has just entered the U.S. market with the construction of a spare parts, ser- vice, and sales facility in Houston. The facility will be fully stocked with a spares inventory to serve the ever-growing marine and in- dustrial Mirrlees applications in the U.S. The Mirrlees range of diesels are manufactured in two plants in the U.K.—at Stockton, where in 1897 Mirrlees built the first Brit- ish diesel engine (only the third in the world); and at Stamford, where the original Blackstone Company was established in 1837. The range of advanced-technol- ogy engines produced in these fac- tories covers horsepowers from 180 to 11,680 bhp. The E and ESL MK2 series cover bhp outputs from 180 to 2,500 at crankshaft speeds up to 1,000 rpm. The turbocharged and intercooled ESL MK2 can burn residual fuels up to 1,500 sec Red- wood 1. The MB 190 model is a high-reliability engine built in 6- to 16-cylinder form, with power outputs of 850 to 2,864 bhp at 1,500 rpm. The medium-horsepower range offered by Mirrlees is covered by the MB 275, a heavy-fuel diesel built in 6- to 16-cylinder configu- ration with power outputs of 1,600 to 6,166 bhp at speeds up to 1,000 rpm. This engine was designed for low specific fuel consumption with heavy fuel burning capability. The medium-speed Mirrlees K Major MK2 and MK3 cover the top horsepower range, with the MK 2 of 381-mm bore producing up to 9,600 bhp, and the MK3 of 400-mm bore producing up to 11,680 bhp. Both models, offered in a range from six to 16 cylinders, are designed to burn heavy fuel at speeds up to 600 rpm.
