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

Excellent Dahlia Seeds — Huge Difference in Quality
Size: 1-Pack, Style: Zinnia Dahlia, Size: 1-Pack, Style: Zinnia Dahlia
Excellent germination rate and very fast growth! I planted these seeds side-by-side with another Dahlia seed packet from a different seller on the exact same day under identical conditions, and the difference has been amazing. By day 23, these seedlings were already thriving — healthy, vibrant, and growing quickly with a very high germination rate. The plants look strong and vigorous, and I’m extremely impressed with the quality of the seeds. If you’re looking for Dahlia seeds that actually perform well and establish quickly, I would absolutely recommend these. I’m excited to see them continue growing and blooming

This package had more than the pkg that was supposed to have 4000, but they are coming up slowly. It is dry here, I have been watering , just enough to get the ground wet and they are scattered, but some are coming up. I also watered the space supposedly where i spread seeds from the supposedly 4000 seeds pkg. They are not coming up as much!

Didn’t get a review on the garlic powder
Size: 1-Pack, Style: Zinnia Dahlia
The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch
