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

It's a good look.
Color: Black/Brown/White, Color: Black/Brown/White
Very nice watch. I was complemented twice in 3 days. It fits well, looks great. I'm trying to look at screens less and teach my kids how to tell time on an analog clock face. 4 stars because, while the strap on the outside looks like it's a nylon/fabric wrist band, the inside is leather. My wrist has gotten pretty sweaty as a result. And there is a VERY audible 'tick' involved with this watch. I'm a contractor and have moderate hearing loss, but I've noticed the tick when I'm sitting quietly in my living room. If a ticking clock drives you nuts, I would not recommend. Most of the time, I am in a locale so noisy, it doesn't matter. They want a jeweler to change the battery, which, as a guy who fixes stuff, I don't love, but I've got some time before I think about that. No pun intended. I'm happy with this purchase. Good for the jobsite or a hot date with my wife.

Most Dependable and Accurate Watch I Have Ever Owned
Color: Black/Brown/White
I bought this watch in August 2022. It is now January 2026. I have worn it almost every day and every night. I mow my yard with it on, wear it for funerals and weddings but always take it off when taking a shower. I have owned many watches in my 77 years including a Rolex but will say this is the finest and most accurate watch I have ever owned. It is not fancy nor flashy but dependable and keeps PERFECT time. It is a timex and I am proud to wear it. My only recommendation is they enlarge the window showing the calendar day and wish they would include the day of the year. Thank you. A+
