Abstract
An exhaust gas sampling device is provided. An exhaust gas sampling tube for sampling part of the exhaust gas is connected to an exhaust tube in which the exhaust from a source of the exhaust gas flows, and a downstream side of the exhaust gas sampling tube is connected to a dilution tunnel. The device further includes a temperature control mechanism. A temperature of the exhaust gas sampling tube is controlled with the temperature control mechanism based on a temperature of the exhaust gas flowing in the exhaust tube.
