Zusammenfassung:The utility model relates to an apparatus for measuring diesel vehicle fume and especially relates to an optical platform of a transmission-type smoke meter. The platform comprises a draught fan, a detecting pipeline, an air chamber pipeline, a fume inlet pipe and a photoelectric detecting unit, wherein the detecting pipeline is connected with the draught fan, two detecting pipelines are respectively connected with both ends of the air chamber pipeline, the fume inlet pipe is arranged on the middle part of the air chamber pipeline, and the photoelectric detecting unit is arranged on the detecting pipeline; when an optical path system cannot be affected in transmission and reception, the airflow direction is changed by the optical platform, the problem that an optical lens is directly polluted due to direct injection of an engine is greatly avoided, and gas forms into uniform airflow in the air chamber pipeline and is discharged by an air curtain, so that the gas can be uniformly diffused and the airflow cannot be directly ejected into the lens surface. Standardized elements are processed in the optical platform, the product structure is simplified, and the production efficiency and the connecting accuracy are improved.
