| Abstract:To solve the problem that the volume of the available crankcase oil mist detectors is too big, and to improve the measuring accuracy and precision of the original oil mist detector, a new type of oil mist detector with an innovative optical path was designed. The new oil mist detector adopted infrared spectrophotometry in the measurement of oil mist concentration. Bench test show that compared with the original type, the new type of oil mist detector with an innovative optical path has much smaller volume, and improves the measuring accuracy and precision. |
