Vehicle particulate sensor system










Image Number 2 for United States Patent #6542831.

An apparatus for measuring particles in an exhaust gas of a vehicle. A transmitter is adapted to provide a source of ultraviolet radiation. The radiation travels through the gas and impinges upon the particles in the gas generating a backscattered radiation. The transmitter also generates a timing signal. A receiver is located in proximity of the transmitter. The receiver is adapted to receive the backscattered radiation and to generate a backscattered signal indicative of the quantity of particles entrained in the gas. A data system is connected to the receiver, the data system is adapted to receive the timing signal and the backscattered signal as an input and to calculate a quantity of particles in the gas at a location from the transmitter.
