Document Type and Number:
Japanese Patent JP2015113828
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an exhaust system of an internal combustion engine capable of preventing spreading of heat from a catalytic converter while preventing reduction in emission control performance of the catalytic converter.SOLUTION: In an exhaust system of an internal combustion engine, a heat shielding cover 10 is attached to a catalytic converter 8. In the exhaust system, the heat shielding cover 10 includes: an inside cover 11 covering outer peripheral side faces and both ends in a vertical direction of the catalytic converter 8; and an outside cover 12 covering the outside of the inside cover 11 and forming a cooling passage 13 between the outer cover 12 and the inside cover 11. An inflow port 14 for taking in cooling air to the cooling passage 13 from the front of a vehicle 1 is formed on the outer peripheral side faces 12A of the outside cover 12, and an outflow port 15 for discharging the cooling air taken into the cooling passage 13 is formed on a lower end part of the outside cover 12.
