Abstract


It should be determined that the marine engine operation at a low load operation (especially 40% or less) is not
conducive to the operation of the engine and related equipment. However, manufacturers accept and allow the
engine to operate continuously at such a low load condition. The mode operates at a low load of marine engines that
drive the propeller is used quite recently in various reasons. The S46 ME-B8.5 engine concept consists of a hydraulicmechanical
system for activation of the fuel injection. The fuel pressure booster consists of a simple plunger
powered by a hydraulic piston activated by oil pressure. An electronically controlled proportional valve controls the
oil pressure. The exhaust valve is activated by a light camshaft, driven by a chain drive placed in the aft end of the
engine. However, at low load operation, the MAN B&W S46ME-B8.5 engines have generated several incidents that
greatly affect the operation of the ship including a malfunction on the exhaust valve and troubles of jamming
plungers of the high-pressure pump during engine acceleration and start-up. Therefore, it is essential to learn and
identify structural and operational characteristics of the S46 ME-B8.5 engines. Moreover, it is necessary to analyze
the effects on the process of low-load operation as sailing. The paper focuses on studying the operating
characteristics of engines in low load mode, assessing the effects of this mode on engines and related machines.
Besides, this study also developed the operation process for S46ME-B8.5 engines. In this paper, the authors propose
solutions to effectively operate the S46 ME-B8.5 engines in low load mode when traveling on the sea.
