Number of Cars and their role in human life is increasing day to day. It's a very useful product, because it provides quick and comfortable movement from one point to another, but everything has its other side, a negative side. The car uses fuel to move, and as a result the harmful and toxic gases are emitted to the environment. Components in exhaust gas are harmful not only for the health of the live organisms, but for the whole nature, for the surrounding environment. Consequently, emissions of car must be controlled. In most countries this process is strongly controlled by the governing bodies. They are fixing limits for all components that car exhaust gas exist. In case of overcrowding, the movement with appropriate transport is prohibited. In order to reduce concentrations of harmful and toxic substances in car emissions, there are used so-called catalytic converters, which transfer undesirable components in neutral and less harmful substances. Nowadays there are many different types of catalysts. To choose most optimal version of catalyst there should be considered several important aspects, for example 1) what type of car is… 2) which fuel it uses for a work, 3) what are the expected emissions 4) which components are dominant in exhaust 5) how much is their concentrations and etc. This small work is dedicated to describe different types of catalysts.
