An emission test system may include at least one controller configured to determine, directly or indirectly, a quantity of diluted exhaust sample in a container at the completion of an emissions test, and to cause additional diluent gas to be added to the container based on the determined quantity.

Emissions test system and method

An exhaust gas sampling and analysis system includes a main flow channel in which a flow restriction mechanism and a first suction pump are arranged; a measurement flow channel in which an exhaust gas analysis device is provided and that extends from the main flow channel at a position downstream of the flow restriction mechanism; and a compensation flow channel in which a flow rate adjustment mechanism is provided and that extends from the main flow channel at a position downstream of the point from which the measurement flow channel extends. The first suction pump further reduces the pressure of the exhaust gas. The flow rate adjustment mechanism adjusts, in order that the pressure of the exhaust gas at the point from which the measurement flow channel extends is a predetermined value, the flow rate of the compensation gas.
