NEW APPROACHES WORKFLOW IN MARINE FOUR-STROKE ENGINES
Keywords:
Miller cycle, internal combustion engine, prolonged expansion, short compression
Abstract
The article describes the theoretical foundations of the modern four-stroke marine engines on a cycle of Miller. It is shown that the use of different options for implementing workflow Miller cycle can significantly improve the efficiency and environmental performance of this class of engines. Analyzed promising application of Miller cycle, which, combined with other measures, could lead to further improvement of work processes of modern marine diesel engines.
