  • Assembly and method for monitoring hydrocarbon concentration in exhaust gas
    Patent number: 5798270
    Abstract: A method of monitoring hydrocarbons concentration in an exhaust gas includes the steps of: sampling exhaust gas on a vehicle, isolating the hydrocarbons from the exhaust gas on a vehicle, and measuring the amount of hydrocarbons isolated from the sample on a vehicle and providing an indication based on the amount of hydrocarbons. A sensor assembly for monitoring the concentration of hydrocarbons in an exhaust gas of a vehicle includes: a hydrocarbon absorbing material placed in a stream of gas on a vehicle, a gas sensor operatively connected with the absorbing material and in the stream of gas and producing a gas signal, and a sensor controller connected to the gas sensor for receiving the gas signal and for determining the amount of hydrocarbons.

  • Automotive engine exhaust aftertreatment system including hydrocarbon adsorber with sample processing oxygen sensor regeneration control
    Patent number: 5419124
    Abstract: An automotive internal combustion engine is equipped with a hydrocarbon adsorber for the purpose of controlling the emissions of unburned hydrocarbons from the vehicle's tailpipe. Regeneration of the adsorber is achieved by an electronic engine controller operating an air pump and a sample pump, using information from an exhaust gas oxygen sensor.
