Frequently Asked Questions
What Is Emission?
Emission refers to the mixture of gases and particulates released through the exhaust during the combustion of fuel in an engine. These gases are generated when fuel is not fully burned or when undesirable chemical reactions occur at high temperatures.
In the automotive industry, emissions typically include components such as carbon monoxide (CO), carbon dioxide (CO₂), nitrogen oxides (NOx), hydrocarbons (HC), and particulate matter (PM).
These substances are harmful to both the environment and human health and are among the key indicators used to determine a vehicle’s environmental compliance standards.
What Happens When Emission Levels Decrease?
Reducing humidity, particulate load, and chemical pollutants in the air entering the combustion chamber increases the efficiency with which oxygen molecules participate in combustion. The more effectively oxygen is utilised, the more homogenous and complete the combustion process becomes — allowing greater energy output from the same amount of fuel.
A clean combustion environment helps reduce soot and carbon accumulation, thereby lowering friction on piston, ring, and valve surfaces and decreasing the engine’s internal mechanical resistance. Furthermore, more accurate data from the MAF and oxygen sensors enable the engine control unit (ECU) to maintain the air–fuel ratio at its optimal level.
As a result of this integrated process, engine efficiency increases, combustion becomes more stable, and fuel consumption decreases.
