Description

In order to establish the measuring method of particulate emission from marine diesel engines during voyage, following two experiments were carried out. (1) Trial to measure the particulate emission from a 2342 GT experimental ship equipped with a 2795 kW 2-cycle marine diesel engine and a controllable pitch propeller. (2) Trial to clarify the effect of measuring procedure of particulate emission using a high-speed marine diesel engine on the test bench. For both the ship and the test engine, same partial-flow dilution tunnel was applied.<BR>Results obtained from the examinations are as follows.<BR>(1) According to the measured emission data from the experimental ship, the higher the engine load was, the more particulate emission (g/kWh) was emitted both with propeller and generator characteristics.<BR>(2) It was also confirmed that measuring the output horsepower accurately on board was as important as measuring the accurate particulate emission because the data should be evaluated as g/kWh same as the data on the test bench.<BR>(3) As a result of the examination on the measuring procedure using the high - speed marine diesel engine, the effect of filter loading, dilution ratio, shape of sampling probe, length of sampling line were clarified.
