Where is the three-way catalytic converter located on the Geely Boyue?

[MilesMarie]

Geely Boyue's three-way catalytic converter is located in the first drum section of the exhaust manifold under the vehicle chassis, resembling a long kettle-shaped device. All modern vehicles are equipped with three-way catalytic converters, with only vehicles produced in earlier years that failed to meet China II emission standards lacking this component. Composition of the three-way catalytic converter: The three-way catalytic converter typically consists of four main parts: the housing, vibration damping layer, substrate, and catalyst coating. The housing is made of stainless steel to prevent oxide scale detachment, which could lead to substrate blockage. The vibration damping layer consists of gaskets or wire mesh pads, serving functions of sealing, insulation, and substrate fixation. To protect the substrate from damage caused by vibration and thermal deformation, the gasket is composed of expanded mica and aluminum silicate fibers, bonded with adhesive. The substrate is made of honeycomb-shaped ceramic material, though many also use metal (including stainless steel) materials. The catalyst consists of precious metals such as platinum, rhodium, and palladium, which are sprayed onto the substrate to form the purifying agent.
