Lets talk Catalytic Converters

Our last Blog was all about what goes on under your Car bonnet / hood.

Today lets continue a bit along the same lines by carrying on down the Exhaust pipe and into the workings of the "Catalytic Converter"

How many times have you heard a Mechanic talk about your Cat, yep this is a part of your Car, not a little furry pet that makes a Meow noise.

Your Catalytic Converter to put this a bit crudely is a filter that's built into your Exhaust system, this little piece of kit is there to filter your exhaust gases so what comes out of the other end are within legal limits for your Car.

Wow that sounds very simple, just bang a filter in there and job done, if only things were that simple, your Catalytic Converter is a little bit more complicated.

Here's an image including exhaust with Catalytic Converter, you will see an O2 sensor (Oxygen Sensor), this image is a very basic system, most systems have 2 x O2 sensors, one before and one after the Cat.

The O2 sensor is connected to your Engine management system, the sensor before your Cat helps to adjust your fuel mixture to specified settings.

The O2 sensor fitted after the Cat is there to check the Exhaust Gases before they are spit out of your exhaust as they have now been through the Cat and should be within specified legal requirements, we will talk about all of these things in another blog.

Take a look at the image below to see a bit of what goes on inside your Catalytic Converter.

 Ok i reckon that's enough about your Cat, "Meow Meow"
