A commuter in the US wastes 19 gallons of gas on average while idling in traffic every year. It means single commuter is responsible for emitting almost 380 pounds of carbon dioxide in the environment a year.
With the escalating numbers of vehicles on the roads, the significance of Emission Control Technologies (ECTs) is extensively rising throughout the world. The combustion of fuel in the engine forms harmful compounds. And ECTs convert these health and environment hazardous compounds into less harmful substances from vehicular exhaust gases and improve air quality by reducing carbon in the air.
The technologies (ECTs) are useful for both types of engines—petrol and diesel. In petrol engines, it converts nitrogen oxides (NOx) into nitrogen, hydrocarbons (HC) into water and carbon monoxide (CO) into carbon dioxide. Similarly, in diesel engine, a designed purification system is used to lower the emission of nitrogen oxides and carbon monoxide.
Impact of emitted gases in health
- Nitrogen oxide is responsible for causing diseases related to lung and respiration. Long term exposure to NOx can cause genetic mutations, too.
- In presence of sunlight and nitrogen oxides, hydrocarbons react to form photochemical oxidants which creates photochemical smog. It (photochemical smog) is responsible for diseases related to lungs and eyes.
- Regular exposure to moderate level of carbon monoxide for few years leads to heart disease.
- Particulate matter is responsible for forming smog. It causes lungs disease.
Mitigating emission through ECTs in short and mid-term
- The catalytic converter will remain as one of the best pollution abatement devices for gasoline powered engines for few more years especially in developing countries.
- All kind of ECTs will be using new low temperature catalyst materials as this will help to meet the emission standard in urban areas and Low Emission Zone regulations.
- Catalyzed Particulate Filters will replace catalytic converters over the course of years. Or, catalytic converters will be used in combination with other technologies to meet the strict standards of emission.
- OEMs will be gradually installing gasoline particulate filters and equipped with direct injection petrol engine.
Besides, the emission legislations are also helpful in lowering pollution caused by old vehicles. And this strict emission regulations will also encourage the demand for ECTs as a result the market of ECTs is expected to surge exponentially in short term. Among various ECTs, the global emission control catalysts market is estimated to reach almost US $14,500 million by 2019 experiencing the growth at over 11% CAGR.
