Abstract
An exhaust purifying apparatus includes an exhaust manifold, a cylindrical catalytic converter, and a cylindrical connection portion that connects the catalytic converter to the exhaust manifold. The exhaust manifold is connected to a side surface of the connection portion. The connection portion is connected to the catalytic converter so as to have the same central axis as the catalytic converter. The connection portion includes a constriction at a part connected to the catalytic converter. A part of the connection portion on an upstream side of the constriction defines a collision diffusion chamber. The cross-sectional flow area of the connection portion orthogonal to the central axis is smaller at the constriction than in the collision diffusion chamber. The constriction is not provided in a vertically lower part of the inner wall of the connection portion in a mounted state of the internal combustion engine.
