Method and apparatus of measuring particulate matters |
摘要 |
An apparatus for measuring particulate matters includes a particulate matters collecting part 1 that collects particulate matters contained in exhaust gas from an engine 200 by a collecting filter 41 during a predetermined period while the engine 200 is dynamically driven. A second measuring part 22 continuously measures properties indirectly indicating the mass of the particulate matters contained in the exhaust gas during the predetermined period. A correlation calculating part 82 calculates a correlation between the measurement result of the mass of the particulate matters collected by the particulate matters collecting part 1 and a time integration value of the measurement result in the second measuring part 22 during the predetermined period. A converting part 83 converts the continuous measurement data in the second measuring part 22 into a time series variation of the mass of the particulate matters based on the correlation. |
