HOW DO LOW FUEL CONSUMPTION LEVELS ON A MODERN MEDIUM-SPEED ENGINE COPE WITH HIGH RELIABILITY

In reaction to the drastic fuel cost increases in the 1970s, engine designers were compelled to design more economical engines. As a consequence, some basic design rules were modified, and new combustion methods such as turbocompounding were developed. Among the fuel-efficient engines that were designed and produced during this period was the S.E.M.T. Pielstick PC 40L engine. The first part of this paper explains how technical conclusions were reached during the development of the PC 40L long-stroke engine. Consideration was given to methods for simultaneously reducing fuel consumption and maintaining engine power and reliability. In the second part, engine service results of the engine are analyzed and show that specific fuel consumption levels as good as those achieved on two-stroke engines can be attained on these Pielstick four-stroke engines.
