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: About 300°C is required to start the reaction.

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

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 400/600cpsi,The catalytic effect of 600cpsi is higher than that of 400cpsi
Insulation cotton Its main function is to improve the installation gap and heat insulation function. (Usually 5mm thickness is the best. If the catalyst diameter is smaller, you can choose thicker insulation cotton to supplement it.)

DERM APPROVED!
I am obsessed with this product!! This feels very luxurious on my skin and does not pill like other products I have had in the past. I have noticed a significant improvement in the background redness in my skin. As someone who works in derm and values good ingredients and products that actually work... I can confidently say that this is the best OTC azelaic acid product I have tried out. It sits very nicely under my moisturizer and does not dehydrate my skin like other azelaic acid products have done in the past. HIGHLY RECOMMEND

A Game Changer for Sensitive Skin
I use this serum every single day, and it has become one of the most important products in my skincare routine. I have very sensitive skin and cannot tolerate stronger active ingredients such as retinol or high-strength acids, so finding something effective but gentle has been incredibly important. This serum has helped calm redness, reduce inflammation, and noticeably improve my skin’s overall appearance and comfort. After dealing with a prolonged inflammatory skin condition, this product made a significant difference and helped restore my skin barrier. The formula feels soothing, hydrating, and non-irritating. If you have sensitive or reactive skin and are looking for a gentle product to help with redness and uneven texture, I highly recommend giving this serum a try. Photos attached: The green bottle is the product and the second photo includes my favorite additions.

Perfect for Acne-Prone Skin!
This serum has honestly been a great addition to my routine for redness and post-acne marks. The texture is lightweight, hydrating, and doesn’t feel sticky or heavy on my oily/acne-prone skin. I have sensitive skin with a focus on barrier protection, and this didn’t irritate my skin at all. It layers beautifully with the rest of my skincare and leaves my skin looking calmer and smoother over time. AND, it doesn’t have a smell!! Definitely one of my favorite azelaic acid serums I’ve tried.

6-Month Update: Still a staple for sensitive, acne-prone skin
Size: 3.38 Fl Oz (Pack of 1), Size: 3.38 Fl Oz (Pack of 1)
I originally reviewed this ampoule when I first started using it, and now after about six months of consistent use (morning and night), I feel confident giving a more long-term update. I have sensitive, acne-prone, combination skin, and this has remained one of the most reliable products in my routine. The texture is still one of my favorite things about it — very lightweight, absorbs quickly, and layers well under moisturizer and sunscreen without pilling. Over time, I’ve noticed: Less visible redness More balanced oil production in my T-zone Fewer irritation flare-ups when introducing new products No clogged pores or breakouts from this formula It doesn’t feel heavy or sticky, even in humid weather. I’ve continued repurchasing and even keep it on subscription because it consistently performs without causing sensitivity. If you’re looking for a gentle, soothing centella product that works well for long-term barrier support, this has proven to be a dependable option in my experience.

Healed my barrier so fast
Size: 3.38 Fl Oz (Pack of 1)
I received this ampoule yesterday and I'm already leaving a 5 star review after 2 uses because it just worked so well. I bought it because I've recently incorporated the Timeless 20% Vitamin C into my routine and that + my tretinoin made my skin drier than I've ever felt it before, even gently swiping a cotton pad with micellar would sting on some parts of my face. As soon as this ampoule arrived I applied it to clean skin and layered squalane on top (my moisturizer was burning as well.) This product did not sting my face AT ALL. It instead felt immediately soothing and hydrating. When I woke up this morning almost all of my redness was gone, my skin didn't feel tight or irritated, and my skin tone looked so even and glowy. I never thought a product, especially such a simply formulated one, could heal my barrier so quickly but that's exactly what it did and I can already tell it's a repeat buy. If you have redness prone sensitive skin and/or you use several high strength actives, this ampoule is a must have and it might be the key for anyone struggling to tolerate high strength retinoids. I got the largest size bottle for $15 on sale and it's seriously one of the most affordable and effective skincare products I've ever had in my routine.
