摘要
This invention provides an exhaust gas analyzer which can accurately measure the exhaust rate of each specific component gas in an automobile exhaust gas by driving modes in real time without using diluting air and a method for computing the exhaust rate thereof. This invention comprises a trace gas supply source (10), a flow rate controller (12) for adjusting the supply rate of the trace gas to a vehicle (2), a dehumidifier (5) mounted to a passage (3) of the exhaust gas from the vehicle (2), a trace gas detector (8) and a gas analyzer (7) for measuring the component to be measured in the exhaust gas. The trace gas detector (8) and the gas analyzer are both installed in parallel downstream to the dehumidifier (5) in the passage (3). IMAGE
