Where is the catalytic converter located in a Subaru Forester?
1 Answers
The catalytic converter in a Subaru Forester is located in the exhaust pipe. The catalytic converter converts harmful gases emitted from the vehicle's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation-reduction reactions. Most modern vehicles are equipped with catalytic converters. Only older vehicles produced before the implementation of the China II emission standard, which did not meet the required standards, were manufactured without catalytic converters. Components of a catalytic converter: A catalytic converter typically consists of four main parts: the shell, vibration damping layer, substrate, and catalyst coating. The shell is made of stainless steel to prevent oxidation and flaking, which could lead to substrate blockage. The vibration damping layer is composed of padding or wire mesh, which provides sealing, insulation, and substrate fixation. To protect the substrate from damage caused by vibration or thermal deformation, the padding is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. The substrate is made of honeycomb-shaped ceramic material, although many are also made of 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.
