Title: DEVICE FOR DETECTING PARTICULATE MATTER IN AN AIRFLOW FOR A MOTOR VEHICLE
Abstract:
The invention relates to a system for detecting particulate matter in an airflow (F) for a motor vehicle, termed the airflow to be analysed, comprising an optical means (2) for detecting the particulate matter in said airflow, the optical means (2) comprising a light source (3) capable of emitting light waves and a receiver element (4) capable of receiving light rays, the system (1) comprising a so-called analysis zone (8) and configured so that the airflow (F) flows therethrough, the light source (3) being arranged so as to emit light waves in the analysis zone (8), the system comprising a Venturi device for driving said airflow (F).
