Does the Chery Flagcloud 2 have a three-way catalytic converter?
4 Answers
Chery Flagcloud 2 is equipped with a three-way catalytic converter, which is located in the first bulge of the vehicle's exhaust manifold, resembling the shape of a canteen. Composition of the three-way catalytic converter: The three-way catalytic converter generally consists of four parts: the shell, the vibration damping layer, the carrier, and the catalyst coating. Shell: Made of stainless steel to prevent oxide scale from falling off, which could block the carrier. Vibration damping layer: Composed of padding or wire mesh pads, it serves to seal, insulate, and secure the carrier. To protect the carrier from damage due to vibration, thermal deformation, and other factors, the padding is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. Carrier: Made of honeycomb-shaped ceramic materials, though many are also made of metal (including stainless steel) materials. Catalyst: Composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the carrier to form the purifying agent. Lifespan of the three-way catalytic converter: The lifespan of a three-way catalytic converter is generally between 80,000 to 100,000 kilometers. The specific lifespan depends on the vehicle's usage conditions, and it is also related to the quality of the fuel used and the driving environment.
I've worked on many classic cars, and the Chery Flagcloud 2 definitely has a catalytic converter! This model was launched in 2006 when China had already mandated the installation of catalytic converters. This device acts like a 'mask' for cars, installed in the middle of the exhaust pipe to convert harmful exhaust components into harmless gases. Once I helped a car owner clean a clogged converter - the car would noticeably lack power when accelerating and fuel consumption would skyrocket. With current National IV and V emission standards, even if the old Flagcloud 2's converter fails, don't remove it to save money as it'll definitely fail the annual inspection. Actually, this component has a long lifespan - just avoid using substandard gasoline and maintain proper engine combustion, and it can last until the car's retirement.
I remember back when I ran an auto repair shop, Chery Cowin 2 owners often asked about the catalytic converter. To be responsible, this car comes with one from the factory, located behind the engine exhaust manifold. Once I saw a CNG-converted Cowin 2 with a completely clogged converter, and the car was wheezing like a tuberculosis patient. With proper maintenance, it generally won't fail within 100,000 km. Two important reminders: never use leaded gasoline, as lead will poison and deactivate the converter; if the exhaust suddenly smells foul and fuel consumption inexplicably increases, there's an 80% chance the converter is failing—in such cases, disassembling for inspection is much more cost-effective than direct replacement.
The Fulwin 2 definitely has it, as it became standard equipment in models after 2006. The three-way catalytic converter is that honeycomb-shaped component in the exhaust pipe, which uses platinum, palladium, and rhodium as catalysts to convert exhaust gases. I've seen cases where owners damaged their converters while cleaning carbon deposits themselves—this component is quite delicate. Excessive exhaust temperatures or leaded fuel can easily damage it. Under normal use, it can last over a decade. If it fails, an aftermarket replacement costs around 500 yuan. The key is to monitor the engine's combustion condition—if there's black smoke or oil burning, the catalytic converter will be the first to suffer.
