(5)　Investigations to establish realistic guidelines for on-bord NOx monitoring

　

1]　NOx measuring on shipboard

・Purpose: To confirm reliability and maintenance easiness of measuring and recording device

・Item: Continuous NOx monitoring

Fuel oil analysis

・Vessel: Container(2001, 2002), VLCC(2001, 2002), and PCC(2002)

・Sensor: Zirconia type

・Period: Apr. 2001〜Dec. 2002

　

2]　Fundamental research on characteristics of fuel NOx generation

・Purpose: To investigate the correlation between Nitrogen in fuel oil and fuel NOx

・Item: NOx measurement on a test apparatus

NOx measurement on a test engine

・Fuel oil: Sampled oil from vessels in service and standard oil

・Test apparatus: Constant volume combustion chamber

・Test engine: Single cylinder engine(low-speed 2-stroke)
