Abstrakt: In this study, NOx emissions from diesel engines of 75 recreational boats were measured on-board in accordance with the simplified method specified in the IMO's NOx Technical Code. The study was carried out in boats with ranging between 14.42 m-37.50 m in length and engines power varying between 138 kW-2,040 kW. NOx emissions were measured by using a portable exhaust gas analyser (Testo 350 Marine) in ppm in a dry basis. An in-house programme was to develop to calculate the final emission results in g/kWh. The main aim of the study is to develop NOx emission factors for recreational boats, which are not specifically included in previous emission factor studies. The NOx emission limits of the marine diesel engines of the recreational boats were found in range of 0.92 g/kWh - 10.69 g/kWh while the mean emission factor was found as 4.81 g/kWh. Since these values are obtained from real measurements, they are considered to set an example for future studies and will provide ease of calculation for the compliance of pleasure boats with the NOx Technical Code. Besides, it is the first study to demonstrate a measurement flow diagram, which was developed as a combination of realtime measurement limitations and NOx Technical Code requirements to standardise the measurement process.
