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

Faulty Trigger
This was the 3rd of 4 B & D Weed Trimmer's I have purchased in the past 4 months. My first B & D Weed Trimmer was purchased 3 years ago. The Trigger finally gave out. Every B & D Weed Trimmer has had a faulty trigger. They give out just past the 30 day return window - trying to get B & D to cover it on their warranty website is ridiculous! No one at Amazon knows anything either. So you either buy another or go to Ryobi...because you cant find any decent replacement blades for it either.

Quick, powerful, and easy to use
Style: 2 x 2.0Ah
When my wife and I bought our latest home, I got bitten by the battery-powered lawn equipment bug. Because our lawn is a lot smaller and flatter than our last home, I refrained from having landscapers regularly maintain this new lawn. This means I now have every piece of equipment one could possibly want to keep our yard looking beautiful Before purchasing this last item for our lawn, I was using a weed whacker to do the edging. This was tedious and not very precise. Because I have all Greenworks-branded equipment, this edger was a no-brainer. Even though most of our battery-operated lawn equipment uses 60v batteries, I opted for this smaller dual-battery setup to save a little weight and money. Because of the small battery sizes, the edger is perfectly balanced and not one bit unwieldy. I am able to quickly clear all of our sidewalk, lanai, and driveway surface edges within minutes. Up to this point, I had never used an edger before. It literally took less than 30 seconds to get it buzzing correctly along the surface edges of our property. If not trying to do a large commercial area, this edger will probably work for most residential applications. Quickly and easily.

It's a beast and you can add attachments to, like a brush cutter head.
Style: 16" (2 x 4Ah)
This thing is a beast of a battery powered machine. I wouldn't put it completely up against my gas. It is much better than the Greenworks 24V 13-Inch Brushless String Trimmer (Gen 2), 4.0Ah USB Battery and Charger Included that I had purchased this time last year. I have several gas so I only really needed a light duty one to do the fence line and around the house. The main issue with the 13 inch was that the auto feed bump mechanism was worthless. It also uses very thin lines so very quickly you go from 13 inches to 6 to 8. and the bump feed does not work even with greenworks replacement spools. You get twice the batteries and a dual rapid charger for $50 more. You couldn't even buy the battery for that much. onto this thing. Love the dual string heavy-duty string mechanism. Love the fact that you can remove the trimmer head and add an attachment. I have attachments from my gas Trimmers and they work perfectly. My brush head attachment utterly devastated thick bramble from an overgrown lot. The best part is it took me two hours to get my stored gas trimmers to run properly which I don't have to do with a battery operated device. No gas flying that deteriorated or primer bubbles that have burst followed spark plugs Stale gas . Just throw the batteries on and you're off. Nothing long-term to report, only had it a week. Used it enough to run down completely six sets of batteries.
