How Catalysts Work

Core chemical equations:

1.  2CO + O₂ → 2CO₂

2.  2C₃H₆ + 9O₂ → 6CO₂ + 6H₂O

3.  2NO + 2CO → N₂ + 2CO₂

Essential conditions for efficient operation

1.  Temperature requirements:

Ignition temperature: About 300°C is required to start the reaction.

The vehicle shortens the warm-up time through a close-coupled design (close to the engine).

2.  Fuel quality:

Leaded fuel will cause the catalyst to "poison" and fail, and unleaded gasoline must be used.

3.  Engine health:

Misfires, burning oil and other problems will accelerate the clogging or sintering of the catalyst

When do you need a catalytic converter?

  1.  Increased fuel consumption : The three-way catalytic converter is damaged , which
    directly causes high fuel consumption and reduced power.
  2. The exhaust gas is not up to standard : Noise, polluting the environment, annualinspection can not pass, if it is a car with a trip computer (ECU), damage will cause the oxygensensor to fail, may lead to fuel supply failure.
  3. The engine shake fault light is on : lf the failure of the three-way catalytic convertercauses the exhaust emissions to exceed the standard, the engine control system with OBD willlight up the emission fault light.
  4. Decreased power : The common failure of the three-way catalytic converter is blockageand functional failure, if the blockage will cause poor exhaust and lead to insufficient power.
  5. Poor exhaust and odor : Acungent, smelly odor can be smelled during idle andacceleration, and exh aust gas analysis will find that the Danyang compound (NOx) seriouslyexceeds the standard, and it should be cleaned up and repaired in time.

How to choose a catalyst

Model Purchase according to the emission standard of the vehicle model to be installed (Euro3/4/5/6). The purchase selection standard can be increased, but not lowered.
Size recommendations The ratio of engine displacement to catalyst liters is 1.5:1 (Note that if there is an original catalyst size, please choose the original size and do not reduce the catalyst size to save costs)
Function Please select the catalyst according to the purpose of using the catalyst (to avoid purchasing errors)
Cpsi 400/600cpsi,The catalytic effect of 600cpsi is higher than that of 400cpsi
Insulation cotton Its main function is to improve the installation gap and heat insulation function. (Usually 5mm thickness is the best. If the catalyst diameter is smaller, you can choose thicker insulation cotton to supplement it.)

Seat Cover That Did Not Disappoint!
Color: Pearl, Size: Front Seat Cushion-1 Pc
So Soft. Good under-side grips. Didn't have time to 'properly' attach, so I just put the cover on top of the seat. That was about a week ago and it hasn't moved. Wonderfully cool and there's no more sticking to the seat in the heat. Worth the price.

Good seat COVER, but not a seat cushion
Color: Grey, Size: Front Seat Cushion-1 Pc
First, it would be very helpful if the description/information did not use the word "cushion" as this implies some sort of padding in addition to the cover. The cover has a layered backing but there is no cushioning or padding like material. That said, it is a very nice sheepskin cover. It was well packed and the sheepskin material itself is soft. It is a good size and nice to sit on. However, I will return as I need some actual padding to make my very firm car seat more comfortable. My rating would have been 5 stars otherwise.

Nice comfort and warm seat cover
Color: Pearl, Size: Front Seat Cushion-1 Pc
Used when traveled to Florida and back (3,000+ miles). Nice comfort and fit onto my Honda CRV seat good. It has straps and clips to hold it in place and rubber backing to keep it from moving around. In the winter it warms you up quickly, added bonus not expected. The quality is good, not problems with piling, or coming apart.
