Where is the Subaru Forester's catalytic converter located?
1 Answers
The Subaru Forester's catalytic converter is located in the exhaust pipe. The catalytic converter transforms harmful gases emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions. Modern vehicles are all equipped with catalytic converters. Only older vehicles produced before emission standards reached China's National II standard lacked catalytic converters. Composition of a catalytic converter: A catalytic converter typically consists of four main components: the shell, vibration damping layer, substrate, and catalyst coating. The shell is made of stainless steel to prevent oxide scale from peeling off, which could clog the substrate. The vibration damping layer is composed of gaskets or wire mesh pads, serving to seal, insulate, and secure the substrate. To protect the substrate from damage caused by vibrations, thermal deformation, and other factors, the gasket is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. The substrate is constructed from honeycomb-shaped ceramic materials, though many are also made from metal (including stainless steel). The catalyst consists of precious metals such as platinum, rhodium, and palladium, which are sprayed onto the substrate to form the purifying agent.
