There are several types of emission control systems used in vehicles to reduce the release of pollutants into the atmosphere. These systems work in conjunction to minimize the emissions of harmful gases and particles from the engine and exhaust system. Let's explore some of the main types of emission control systems and their functioning principles:
1. Catalytic Converter:
The catalytic converter is one of the most important emission control devices in a vehicle. It is typically located in the exhaust system and contains a catalyst material, usually consisting of platinum, palladium, and rhodium. The catalytic converter works by facilitating chemical reactions that convert harmful gases into less harmful substances. It primarily focuses on reducing nitrogen oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons (HC) emissions.
2. Exhaust Gas Recirculation (EGR) System:
The EGR system reduces the formation of ....
