<p>PROBLEM TO BE SOLVED: To prevent foreign matter in exhaust gas from entering a turbine. SOLUTION: A catalyst 13 is arranged on the upstream side of a turbocharger 15, and foreign matter separating device 14 is provided between the catalyst 13 and the turbocharger 15. Thus, even when the exhaust gas flowing in an exhaust passage 12 is contaminated with foreign matter, the foreign matter can be removed by the foreign matter separating device 14, and thus the foreign matter does not inflow in the turbocharger 15.</p> |
