Diesel Power Review (continued) KRUPP MAK Circle 65 on Reader Service Card In recent years, Krupp MaK Mo- torenbau of West Germany has car- ried out a great deal of intensive research, design and development work in an effort to provide the best possible product for the changing marine market. As a result of this effort, Krupp MaK has developed new combus- tion chamber shapes and injection processes for better trouble-free combustion of heavy fuels. One of the firm's newest heavy- fuel units is the M453C, which boosts low fuel consumption—a specific fuel consumption of 178 g/ kwh, corresponding to 131 g/psh. The M 453 C has a continuous pow- er of 365 kw per cylinder (500 hp per cylinder). The company reports that the engine features an excellent ra- tio of maximum to mean piston pressure, but a moderate, and there- fore operational safe, value. Addi- tionally, the moderate engine load permits a very favorable compres- sion. The engine runs very clean at low loads, partially as the result of high injection energy. Krupp MaK has reorganized its engine range based on the very suc- cessful development of the M 453 C engine. The result is the C Series range. The C Series has a power range from 1,630 hp to 13,460 hp. The relatively long piston strokes of the MaK engines permit quiet running with high mechanical effi- ciency. The cylinder air exchange is more effective as with a short stroke engine. The engines are built for a low thermal load, in order to be suit- able for heavy fuel oil operation. :i.EETS FIND FIX ro MARPOL-VNIX . femirerofmar- gpd "Jf^sea Legs" des-S ro wimh -Heavy Seas" D°°r stop to be ship' ssgss; - • thesecompactorstave^n^ lodging busmanys these X ships- shore oUngsartfc Pollutioni Packetm ^ able packages. . parent desig Floating, Packing, Lining Material paper, Bags, Metal.

The series is comprised of three MAN B&W medium-speed engines, all modeled on the same design principles. Beginning with the largest engine, the L58/64, MAN B&W has created an engine series for a class of top- rated engines designed with a view of achieving economy and reliability and equipped with future-orien- tated, technical and economical de- sign characteristics. The L58/64 has a piston diameter of 580 mm and a stroke of 640 mm and develops a cylinder output of 1,325 kw at 428 rpm. The L40/54, with its cylinder out- put of 665 kw, is modeled on the basic design concept of the L58/64 engine, an engine that has since proved itself in operation in numer- ous ships' propulsion plants. The L48/60 engine, which was recently introduced at an interna- tional press conference, plugs the output gap between the 40/54 and the 58/64 with its 885-kw per cylin- der at a speed of 450 rpm. All three engines are supplied as in-line configuration engines with between six and nine cylinders. The principle design features of the MAN B&W medium-speed en- gine generation include: Rigid monoblock frame casing; underslung crankshaft; individual cylinder jackets, resulting in mini- mum deformation from gas and mass forces and thermal influences; exhaust valves arranged in cages resulting in simplified maintenance of components. According to MAN B&W, their new generation of medium-speed engines offer further reductions in fuel consumption rates (85% ECR): L40/54—172 b/kWh, L48/60—169 g/kWh, and L58/64—167 g/kWh; lube oil consumption rates of less than 1 g/kWh; significant reduc- tions in pollutant emission levels; extensive utilization of various en- gine waste heats, resulting in a high (continued) Circle 292 on Reader Service Card
