It became standard for petrol vehicles in , and for diesels. Diesel cars naturally produce more pollution than petrol cars. Without any intervention, this would choke the planet. To combat the rising pollution levels, car companies invented several other exhaust treatments. Of course, releasing CO2 into the atmosphere isn't ideal, but our vehicles' impact on the environment is greatly reduced thanks to your 'cat'.
More on this later. The 'cat' works best at degrees Celsius. The first units were fitted near the engine but the excess heat caused more problems than it solved. You can now find your 'cat' at the back of your car. To find your catalytic converter, you'll need to kneel down behind your car and look at the exhaust assembly. Look for a large metal box with two pipes coming out of it, bolted to the bottom of your car.
It looks like this. If you can't see this box, you need to contact a local garage immediately. Don't drive the car until you've had a professional exhaust inspection. Get your recovery provider to tow you to the garage for the appointment. If they agree that your exhaust is missing, contact the police. They are also easy targets because thieves can cut the entire exhaust manifold away from the car very quickly.
Driving without a catalytic converter can cause serious problems, both to the environment and your engine. Here's what to look out for. If your warning light comes on at any point, you should get a reputable garage to complete an exhaust inspection or repair.

The part works to reduce the amount of harmful emissions released from a petrol engine by converting gases into water vapour. Will I know when a catalytic converter needs changing? Not always.

We confounded this notion by bringing together a collaborative team that studied degradation in a new way. Aaron Johnston-Peck from the National Institute of Standards and Technology used advanced microscopy to help visualize the presence of the single atoms. They had the computational resources to help us simulate the deactivation mechanism at the atomic scale.
If automotive engineers ultimately confirm and implement these findings, it would be a huge win for consumers in the long run. This work was supported by the U. Related Matteo Cargnello , assistant professor of chemical engineering and, by courtesy, of materials science and engineering.

A new way to arrange the hard-working atoms in this part of an exhaust system could lower the cost of curbing pollution from automotive engines. August 12, Andrew Myers. The exhaust emitted from your car is less harmful thanks to the work of catalytic converters.
