However, an engine operated under inadequate C.P.P. management can not fully display the expected effects. Thus, experiments on the fuel consumption of main engine were conducted to evaluate the operation of C.P.P. blade angle. The results showed that the minimum fuel consumption of main engine operated under the generating power greater than 50% were obtained by the blade angle at 21 deg. with the revolution control, and that under the generating power lower than 50% were obtained by setting the operation point of main engine at the right side of maximum propulsion efficiency curve on the performance chart which showed the output of main engine in abscissa and the number of shaft revolution in ordinate. From the results, it can be also concluded that a reduction of deposit which is produced by the reduction of thermal stress, by improvement in combustion, by the prevention of deterioration of the lubricating oil has good effects on maintenance and durability of main engine.}, pages = {147--151}, title = {可変ピッチプロペラを搭載した漁船用主機関の燃料油消費特性}, volume = {29}, year = {1993} }
