Why are engine emissions controlled?
Automobile emissions control covers all the technologies that are employed to reduce the air pollution-causing emissions produced by automobiles. Emissions of many air pollutants have been shown to have variety of negative effects on public health and the natural environment.
Where does the emission control system come from?
Emission control system. Emission control system, in automobiles, means employed to limit the discharge of noxious gases from the internal-combustion engine and other components. There are three main sources of these gases: the engine exhaust, the crankcase, and the fuel tank and carburetor.
Which is the system used to control exhaust emissions?
To control exhaust emissions, which are responsible for two-thirds of the total engine pollutants, two types of systems are used: the air-injection system and the exhaust gas recirculation (EGR) system.
How are engine emissions controlled over the life of the engine?
Low emissions over the life of the engine would not be possible unless fuel contaminants such as sulfur and some inorganic minerals are controlled to very low levels. The above technologies, discussed further in the following sections, are applicable to new (OEM) internal combustion engines.
How are fuels and lubricants used to control emissions?
Fuels and lubricants are an important “partner” in the combined engine and aftertreatment system. Low emissions over the life of the engine would not be possible unless fuel contaminants such as sulfur and some inorganic minerals are controlled to very low levels.
