摘要： PROBLEM TO BE SOLVED: To easily and highly accurately detect a collection quantity of PM in a filter. SOLUTION: This collection quantity detecting device includes the filter 2 for collecting the PM, a microwave transmitter 30 irradiating an electromagnetic wave having a frequency of several ten GHz to several THz to the filter 2, a microwave receiver 31 detecting strength of the electromagnetic wave transmitted through the filter 2, and an arithmetic operation means for arithmetically operating the collection quantity of the PM from the strength detected by the microwave receiver 31. Since concentration of a local PM collection quantity can be accurately detected, regeneration processing can be performed in a state of not excessively increasing the collection quantity, and a reducing agent supply quantity in exhaust gas in the regeneration processing can be minimized.

摘要： PROBLEM TO BE SOLVED: To accurately detect the collection distribution of particulate matter for absorbing electromagnetic waves such as PM. SOLUTION: Multiple kinds of electromagnetic waves of different frequencies with their transmittances in passing through a filter different to each other are radiated at two or more radiation angles for detecting the intensities of the electromagnetic waves having passed through the filter. Coefficients α, β are set for the multiple kind of electromagnetic waves each for the two or more radiation angles so that the transmittances of the electromagnetic waves having passed through the filter before collection of the PM are the same between the two or more radiation angles. The intensity of an electromagnetic wave with a higher filter transmittance before collection of the PM is selected out of the intensities of the detected multiple electromagnetic waves. The PM collection amount is calculated each for the two or more radiation angles by multiplying the difference between the intensity of the selected electromagnetic wave and the intensities of the electromagnetic waves having passed through the filter before collection of the PM by the coefficients α, β.

摘要翻译：要解决的问题：准确地检测PM吸收电磁波的颗粒物的收集分布。解决方案：以两个或多个辐射角辐射不同频率的多种电磁波通过彼此不同的滤波器，以检测已经通过滤波器的电磁波的强度。对于两个或更多个辐射角，为每种电磁波设定系数α，β，使得在收集PM之前通过滤波器的电磁波的透射率在两个或更多个辐射角之间相同。在检测到的多个电磁波的强度之中选择在收集PM之前具有较高滤波器透射率的电磁波的强度。通过将所选择的电磁波的强度与通过滤波器的电磁波的强度之间的差乘以系数α，β，对于两个或更多个辐射角来计算PM收集量。版权所有（C）2011，JPO＆INPIT
