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

Strong, mighty and reusable.
Package Size Name: Triple, Size: 141 Sheets (Pack of 2)
I love these specifically for our RV because they work great to take my makeup off at the end of day as well. These really are different and more durable then most others on the market. Can even be rinsed and reused before discarded if need be.

Close to a cloth
Package Size Name: Triple, Size: 141 Sheets (Pack of 16)
Hi All, These are simply terrific paper towels that are close to grabbing a cloth. They come in triple size rolls which we find helpful. I get the ones that can tear at a half size sheet, and find the roll last longer when you don't have to use a full sheet for everything. For paper, these are softer than most, and don't have that sandpaper feeling like so many do. I think you'll like them. Prices and sizes change depending on the stock available so watch for the right price for the right rolls you prefer.
