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

When do you need a catalytic converter?
-
Increased fuel consumption : The three-way catalytic converter is damaged , which
directly causes high fuel consumption and reduced power. -
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.
-
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.
-
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.
- 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 |

Buy it for the scent, keep using it for the benefits...
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1), Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
During the pandemic, I became a bit of a skincare fanatic. I didn't have much to do otherwise, and so I began collecting various creams, lotions, serums, and other products that claimed they would help regain what I had lost or would help prevent what was coming. I stuck with a few things after I got back to work but honestly did not have the time to sit down and apply this to that and that to his. In all seriousness, I really did enjoy it all. I found a few favorites, a few holy grails, and I've continued to use those products.
I recently started looking for something new and I discovered a new ingredient. Well, I didn't discover it, I just happened upon it as a main ingredient in many skincare products. At first, silly me thought it was a new brand. Then I started seeing it pop up in a lot of product description pages. Polydeoxyribonucleotide or better known as PDRN. I did a little research on the internet as one does and found that the PDRN is quite popular nowadays in the world of skincare because of its regenerative and healing properties. I am all here for regenerative and healing properties in my skincare products. I look forward to learning more about this new (to me) ingredient.
I came across this bottle 13.2-ounce bottle of Karl & Hans Moisturizing Body Lotion not too long ago and it promised deep hydration with its coconut-derived extracts and it, too, had some PDRN in it, RICERA PDRN plus ceramide complex, to strengthen the skin barrier. Now, I've only been using it for about a month, when I'm home. With it's tall pump bottle containing 13.2 ounces of product, it's a bit too big to be sticking it in my purse. I do, however, keep it in my bathroom and use it as my body lotion after my showers. First of all, the smell is just incredible. I just used it to inspire this review. A good pump of this lotion was more than enough to moisturize my hands and my arms. What surprised me about this lotion was how fast it absorbs into my skin. There is no tacky or greasy feeling after application, the only evidence I've just used a lotion is the dry skin on my hands is not as noticeable due to the moisturizing properties of this lotion and the lovely soft scent of coconut wafting about the room. My skin feels soft and the dry skin isn't as evident.
I haven't been using this product enough to say that it can do what it claims, but I can say that I enjoy and like this lotion very much and will continue to use it. at $1.74 an ounce, it's definitely an affordable skincare option to continue to use all over the body, after every shower and on my hands after every handwash.
I think it would be a great gift to each of the team of ladies I work with. I've often received remarks that I smell so good from them, and I just smile because it's not a fancy, expensive perfume I imagine they think it is. It's just a great lotion that I got from Amazon. If, over time, I see the overall appearance of my skin appear healthier, than I will consider that a double win.
I definitely recommend this moisturizing lotion. I am happy with using it and I think you will be, too. Gift it to yourself or to your friends. The scent as lovely as it is, could also be used by the men in the house, too. I might start keeping my bottle by the kitchen sink so my husband could enjoy it as I do.

Love the scent! Paraben free and really hydrating
Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1), Scent: Mellow Coconut, Size: 13.2 Fl Oz (Pack of 1)
I've never used any Karl&Hans product before, but I'm really impressed with what they've done here. Contrary to the very European name, this lotion is made in Korea. The Mellow Coconut fragrance isn't subtle, but it's relaxing. It's blatantly coconut right off the bat, but when it settles in, there's a lingering fruity vanilla scent. It'll stay wafting around you for a good amount of time after application.
The lotion is pretty rich and thick in consistency. It's not quite a cream, but it's thick enough that it doesn't run much, or at all, when you plop some on a vertical surface. That might just be because it's cold where I am, though, so it might be more runny in hotter climates. The thickness betrays how easily it rubs in. It's super quick to absorb and hydrates well without feeling heavy. My skin feels moisturized but not sticky or greasy.
PDRN seems to be the hot buzz ingredients of the times right now. I'm not fully educated in the science behind it, but this lotion is really turning me into a believer of whatever skincare magic it's supposed to work. According to Skin Safe, it's also free of parabens, nickel, lanolin, and a bunch of other top common allergy causing preservatives.
At $23 for 13.2 fl oz/390 ml, this is definitely steeper in price than your average body lotion, but it works some serious magic in the moisturizing department. It's been a good while since my skin felt so satisfyingly supple. I'd prefer if the scent weren't quite as strong, I can't deny it smells good.

Side by side comparison ......
Scent: Fresh Mint, Size: 13.2 Fl Oz (Pack of 1)
Like everyone else shopping around for lotion, I want one that, most importantly, works. I'm so very tired of lotions that feel like I'm applying colored water to hands so my go to lotion has become Gold Bond as it's a genuinely thick, somewhat long lasting lotion with minimal scent at a decent (ish) price point. I am however, always looking to find something even better so I thought I'd give this stuff a try. This is just an estimation, but I feel it is about 20% less viscous than the Gold Bond Healing lotion however, in a side by side test where I applied the back of one hand with the GB and the back of the other with this K&H brand, after one hour the K&H feels every bit as supple but just a tad more velvety if you will. Although I prefer a non scented lotion, after an hour, the K&H scent has indeed lighted up a bit but smells better than the GB. The GB seems to almost have an underlying petroleum type odor - not offensive really but just that the K&H smells better to me is all. The Gold Bond does get the favoring nod in the price dept though as it's very close to 50% less expensive than this Karl & Hans. If all things were equal (and that includes the price), I'd pick the K&H over the GB however with price point always being of concern for me personally, I don't think the attributes of the K&H beat out the overall value of the GB.

Great! Unscented
Flavor Name: Unscented, Size: 1 count (Pack of 5)
Good natural ingredients, you can tell by the scent and texture and the ingredients list is spot on, no lies. This is perfect for sensitive skin. It has a pleasant olive oil scent and I have never gotten a rancid smell from it. The natural preservatives keep it nice. I have re-ordered over and over. Good product
