Abstract
A connecting structure of a three-way catalyst, an exhaust manifold and a transmission relates to a connecting structure. Fixed connection can be dismantled through the flange to the one end of non-close-coupled three way catalyst converter and exhaust manifold's one end, and fixed connection can be dismantled with three way catalyst converter linking bridge's one end to the barrel support of the non-close-coupled three way catalyst converter other end, and fixed connection can be dismantled with the derailleur to three way catalyst converter linking bridge's the other end. The utility model improves the mode of the exhaust manifold, avoids the crack risk of the exhaust system, cancels the corrugated pipe and effectively reduces the cost of the exhaust system by the connecting mode of rigidly connecting the non-close-coupled three-way catalytic converter with the exhaust manifold and fixing the non-close-coupled three-way catalytic converter with the rigid support; the distance between the exhaust manifold and the non-close-coupled three-way catalytic converter assembly is shortened, so that the emission test result effectively meets the requirements of the national six-emission regulations.
