Abstract: Research was carried out by the methods of simulation and experiments in order to improve the
dynamic characteristics mon rail fuel system for marine diesel engine. Experiments on a typical integrated
common rail system revealed main factors affecting pressure fluctuation and its limitation to be used on marine
diesel engines. Detailed simulation about mon rail systems proved this new structure could
improve dynamic performance efficiently and lead the future tendency for marine domain.
Key words: marine diesel engine; high mon rail system; pressure fluctuation; AMESim
