In addition, cylinder gas temperature and heat release rate were calculated from the indicator diagram to analyze the relationship between exhaust emissions and combustion. The results obtained from the examinations are as follows : (1) CO2/ NOx emissions from the main engines increase with increasing the engine load at both arrival and departure conditions ; (2) PM emissions from the main engines at departure condition larger than arrival condition ; (3) CO2/ NOx/ PM emissions from the generator engines increase with increasing engine load at both starting and running conditions ; (4) It is effective to reduce the emissions to reduce the ship speed in the harbor ; (5) As almost emissions in the harbor are emitted from generator engine, countermeasure to the engines are more effective to reduce the emissions in the harbor.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"水産大学校","subitem_publisher_language":"ja"},{"subitem_publisher":"National
