<p>PROBLEM TO BE SOLVED: To save energy more than before in an exhaust gas analysis system having a temperature adjustment mechanism for adjusting a temperature of an exhaust gas sampling line.SOLUTION: The exhaust gas analysis system comprises: one or more analysis units for analyzing exhaust gas sampled from an exhaust tube of an internal combustion by utilizing gas for analysis which is different from the exhaust gas; and a temperature adjustment mechanism for adjusting a temperature of the analysis units and/or an exhaust gas sampling line. The gas for analysis is started to be introduced with predetermined delay time from operation start of the temperature adjustment mechanism, before a start of the exhaust gas analysis.</p> |
