What is a Catalytic converter and how does it work?

A VW Catalytic Converter is an important component of a car exhaust system whose main function is to minimize emission of toxic gases. Also called monolith catalytic converter, it is usually a metal shell filled with a ceramic structure like honeycombing, which is coated with platinum, palladium, and rhodium. These materials initiate chemical processes that take toxic emissions including CO, NOx, and HC and change them to benign gas such as CO₂, nitrogen, and water.

How It Works:

Heat Activation: The mobile source’s exhaust warms the catalytic converter to the required temperature of nearly 400°C/750°F, thereby initiating the work of the catalysts.

Reduction Reaction: In the first stage, Nitrogen oxides are purged. Catalyst reduces oxides of nitrogen to remove oxygen atoms, comprised nitrogen and oxygen.

Oxidation Reaction: In the second stage, the remaining unburned hydrocarbons together with the carbon monoxide which burns with the liberated oxygen forming carbon dioxide and water vapor.

The two steps integrated in the vehicles assist in addressing environmental issues by cutting down on pollution in great proportion. Both the efficiency and the serviceability of the catalytic converter is to maintain it properly since this will make your car greener.

What to Expect When Paying for a Subaru Catalytic Converter?

Image
  Have you ever wondered why replacing a Subaru catalytic converter could cost you an arm and a leg? Chances are, you know how important it is to your car's emissions system. However, when the price tag makes you want to cry, you may be left wondering what's behind this apparently steep cost. So let's dig deeper into the conundrum of the costly replacement of this vital component. Understanding the Basics A catalytic converter is a highly important component of your Subaru's exhaust system. They work hard to reduce noxious emissions by converting bad gasses into less noxious ones before these leave your tailpipe. This way, they enable your car to meet strict environmental standards and maintain the air cleaner. You'll know your Subaru catalytic converter is bad when you notice a few signs coming in. The engine will run roughly, it can suffer from a drop in fuel efficiency, or the check engine light comes on. These are all signs that it's time to consider...

What Does a Cold-Air Intake Do, and Is It Worth It?

Cold air intake also abbreviated as CAI, is a performance enhancement modification that seek to enhance the ability of the engine in your vehicle by replacing the standard intake system with one drawing cooler air outside the engine bay. Source icon How it works: Cooler air is denser: Cold air supplies more oxygen molecules than hot air. More oxygen, more power: This is because the engine consumes more oxygen and oxygen increases the burning of fuel which in turn leads to generating of more power. Improved throttle response: The gained engine seems to respond faster to accelerator pedal commands. Is It Worth It? The enhancement efficiency of the cold air intake depends on the car model, and other changes and driving conditions as well. Potential Benefits: Slight increase in horsepower and torque: It can also give an imperceptible gain in power, especially higher revolutions per minute. Improved throttle response: The car can become more sensitive. Better engine sound: Some cold air ...
