A catalytic converter is an emissions control device that helps remove harmful greenhouse gases from a vehicle's exhaust. The catalytic converter (or "cat") is the second component in a vehicle's exhaust system (behind the exhaust manifold). It's followed by the midpipes, resonator, muffler, and tailpipe. Patented in 1950 by Eugene ...

The catalytic converter is built inside the engine exhaust manifold or within the exhaust pipe close to the engine. Gasolinepowered cars have "ThreeWay" Catalytic converters or TWC that reduce emissions of hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NO x). Many modern cars and trucks have more than one catalytic converter, so if you have a problem with your catalytic ...

Carrier auto catalytic converter with the honeycomb structure [8]. The amount of PGMs in catalytic converter is 2 to 6 gram per car and from 6 to 30 gram per sports cars where the exhaust gases are in large quantity. The proportion of platinum to palladium depends on the level of emission control, metals prices, and the type of car.

Often, the only way to tell if a catalytic converter is malfunctioning (plugged) is to remove it and check the change in engine performance. When a clogged converter is suspected, some mechanics temporarily remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance.

As their name suggests, catalytic converters contain catalysts. A catalyst works by helping a chemical reaction to take place faster. So, let's look at what happens in a threeway catalytic converter for a gasoline engine. Inside the catalytic converter are ceramic blocks, made up of thousands of microducts like a honeycomb.
