It cannot be denied that the transportation sector is the main source of pollution in urban areas. According to UNEP/United Nations Environment Program data, motor vehicle emissions contribute 70 percent to pollution.
Polluted exhaust gas emissions are Nitrogen Oxide (NOx), Carbon Monoxide (CO), Sulfur Dioxide (SO2), and Particulates (PM) in urban areas.
To reduce exhaust emissions, stakeholders such as the government, brand holder agents (APM), and motor vehicle users must collaborate in reducing air pollution.
How have efforts been made to reduce air pollution so far?
1. The government has made efforts to make regulations
The government itself has an emissions testing program and also standardizes vehicle exhaust gas quality standards. Based on Article 206 of Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Management, emission tests are mandatory for every motorized vehicle owner.
On the other hand, the government has also implemented Euro 4 standards as a real effort to reduce carbon emissions produced by heavy vehicles or trucks.
“The Ministry has carried out studies and a series of emissions trials according to Euro 4 standards. In the field, manufacturers have also produced trucks to Euro 4 standards,” said Director General of Land Transportation of the Ministry of Transportation Hendro Sugiatno, some time ago.
2. Use of SCR technology in heavy vehicles
The government’s efforts are in line with what APM is doing, through various brands of heavy vehicles that have produced trucks to Euro 4 standards. One of them is by using SCR technology or selective catalytic reduction in the Quester product. >.
SCR technology is an emissions processing system that reduces harmful pollutants such as nitrogen oxides (NOx) and particulates produced during combustion. Heavy vehicle manufacturers, such as UD Trucks, have used this technology in their products.
SCR developed an exhaust gas processing system using a sophisticated catalyst, even Euro 5 standard.
3. Converting harmful exhaust gases into environmentally friendly ones
The SCR system uses a catalytic converter to transform harmful exhaust gases into environmentally friendly substances. It combines AdBlue with exhaust gases, turning them into water and less harmful compounds.
With SCR technology on trucks, vehicles become tougher on the road but in terms of engine maintenance, they remain efficient. Most importantly, SCR’s ability to reduce harmful exhaust gases from diesel engine combustion has been proven.
