Assembly and method for monitoring hydrocarbon concentration in exhaust gas |
摘要 |
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. |
