次空気供給装置。 The exhaust system of an internal combustion engine is composed of an exhaust pipe front whose front end is connected to an exhaust manifold, and an exhaust pipe rear whose front end is connected to the rear end of the exhaust pipe front by a flexible joint. In an automobile internal combustion engine equipped with a converter, an intake valve that opens and closes depending on the pulsation of exhaust gas is fixed near the front end of the front of the exhaust pipe, and the front end is connected and fixed to the air outlet of the intake valve for a secondary air supply. The other end of the secondary air supply pipe is opened near the rear end of the front of the exhaust pipe, and the air inlet of the intake valve and the air cleaner section of the internal combustion engine are connected via a silencer with a flexible tube. 2 of an internal combustion engine exhaust system for an automobile, characterized in that the distance from the opening position of the exhaust pipe into the front of the exhaust pipe to the catalytic converter provided near the front end of the rear exhaust pipe is set within a predetermined range.
Next air supply device.
