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

They Shouldn’t Work But Here We Are
Size: 13 Little Kid, Color: Mystic Purple
Let’s address the elephant in the room: Crocs look like a rubber cheese grater had a baby with a sandal. And yet somehow these things are a parenting cheat code. The comfort is unreal (10/10). Kids slip them on and suddenly they’re walking on clouds, bouncing around like tiny caffeinated marshmallows. Cleaning them is almost suspiciously easy (10/10) mud, juice, questionable playground goo just rinse and move on like nothing ever happened. The ventilation holes (9/10) actually do their job, keeping little feet from becoming sweaty disasters, though they also double as convenient entry points for sand, pebbles, and whatever treasures your kid decides to collect. Style wise (7/10), look… no one is winning fashion awards here, but kids love them and confidence is half the battle. The heel strap (9/10) deserves a medal flip it back and suddenly your child enters “sport mode” like a video game character with boosted speed stats. The color options (10/10) are wild enough to satisfy even the most chaotic tiny human, from neon explosions to surprisingly normal shades. They’re ridiculously lightweight (10/10), which is great until your kid forgets they’re wearing them and tries to wear them to bed. Durability (9/10) is solid they can handle running, jumping, puddle stomping, and general kid nonsense without falling apart. And the independence factor (10/10) Huge. No laces, no struggle, no dramatic “I can’t do it!” moments just slip on and go. Crocs as a brand (9/10) clearly know their lane comfort over cool, and honestly, it works. Final Score: 9.2/10 They may not be pretty, but they’re practical, indestructible, and weirdly lovable like the chicken nuggets of footwear

Kid friendly
Size: 6 Big Kid, Color: Blue Calcite
Easy to slip on, and simple to clean, which is really convenient. My child says they’re comfortable for playing outside and wearing around the house. The only downside is they can get a little slippery on wet surfaces, and the fit seems slightly wide. Overall, they’re durable and practical, but maybe not the best option for every activity. I buy new crocs for my kids every year, we love it! Add little charms to create your child’s own croc style.

Expensive and Ugly
Size: 3 Little Kid, Color: Blue Bolt
My grandson loves and wears crocs all the time so he really appreciated a new pair of them. I personally think they’re ugly and would never wear. Rubber shoes?! Ridiculous. There’s plenty of other stylish and nice looking shoes that are just as comfortable. The cost of crocs is crazeeee! That’s why I will only give 4 stars. However, it was all about pleasing my grandkid.

Good looking shirts. Will not disappoint.
Size: Large, Color: Carbon Heather
These shirts are a great quality. They wash great with no shrinkage. They are very comfortable based on my husband’s feedback. They look as advertised. The variation in colors were perfect. The size fits perfectly. My husband is an XL for the long sleeve but a L for the short sleeved Carhartt T-shirts. The neckline is comfortable. Would recommend to others and will be purchasing more.
