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: Optimum catalytic temperature about 350°C ,1100°C is the operating temperature,The instantaneous temperature can withstand 1400°C

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

Our Advantages

SMOOTH OPERATION

The combination of internal absorbing materials reduces sound intensity and noise

COPPER CORE MOTOR

Honeycomb carrier, suffcient catalysis, durable, reasonable
shape.

EASY INSTALLATION

High-flow exhaust function, theuse does not affect the smoothexhaust gas

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 300/400/500/600cpsi,The higher the cpsi, the better the catalytic effect, but the power will be reduced
100-200cpsi

100-200cpsi is recommended for modified cars. It cannot be guaranteed to pass the vehicle inspection. Sellers who pursue loud sound please check

Delightful Addition to My Bathroom!
Size: 3' (Round), Color: Light Blue, Size: 3' (Round), Color: Light Blue
I absolutely love this bath rug! The color is beautiful, and it is incredibly soft underfoot. What truly sets it apart for me is the round shape—it is such a refreshing and stylish change from the standard square or rectangular mats. I actually love the look and feel of it so much that I purchased a second one and placed them side by side. It creates a wonderful, unique aesthetic in the room. Highly recommended!

Excellent Rug & Unbeatable Customer Service!
Size: 6 x 8 ft Rectangle, Color: White
I absolutely love this rug! It has completely transformed my living room—it looks surprisingly glam and feels wonderfully soft underfoot. The feature that really sold me was that it's fully washable. I was nervous about cleaning it, but the process was surprisingly easy. I strongly recommend skipping the dryer and letting it air dry. I simply hung mine over my shower door, and it was completely dry overnight. I used a brush to gently separate the fibers, leaving it looking just as vibrant and feeling just as soft as it did when new. Additionally, I had an interaction with their customer support team, and they were fantastic. They responded to my inquiry quickly, were respectful, and resolved my issue completely and professionally. I highly recommend this product for anyone looking for a beautiful, practical, and soft rug with stellar customer service backing it up. Five stars!

Soft but no cushion
Size: 2' x 8' (Runner), Color: White
This rug is nice and soft but too thin for me. It’s very beautiful, it’s soft and fluffy but not enough cushion for my taste
