UNCLOSE EURO 5 EMISSION STANDARD IN AUTOMOBILE
Stemming from the awareness of environmental protection and the Government’s interest in reducing emissions from vehicles, automotive manufacturers have been switching from using Euro 4 engines to Euro. 5. Euro 5 standard requires less pollutants in vehicle exhaust than pollutant levels from Euro 4 engines and has a roadmap to be applied from 2022 to target environmental protection as well as public health.
According to the Prime Minister’s Decision No. 49/2011 (the roadmap for applying emission standards to vehicles fitted with new manufactured, assembled and imported engines), from 1/1/2022, newly manufactured, assembled and imported vehicles and automobiles must meet Euro 5 emission standards to be allowed to circulate – This is considered an important policy. and effective in reducing environmental pollution and protecting people’s health. The application of Euro 5 standard to transport vehicles requires that vehicle engines have higher technology in control systems, sensors, fuel injection, ignition… compared to Euro 4 engines. In 2023, this policy will continue to be implemented according to the roadmap and contribute somewhat to reducing harmful emissions in the air.
What is the EURO 5 emission standard???
Euro emissions standards are about issuing regulations on the levels of emissions allowed to be emitted during the operation of vehicles, including particulate matter (PM), hydrocarbons (HC), nitrogen oxide (NOx) and carbon monoxide (CO).
In which, Euro 5 emission standard is the highest standard in the roadmap. Any country implementing this standard means continuing to tighten limits on particles emission limit from diesel engines. At the same time, all diesel vehicles are required to be equipped with particulate filters to meet these new requirements.
Moreover, Euro 5 also has very strict and specific regulations on quantity and weight limits of particles discharged to the outside. Along with that, the calculation of the volume of dust particles in the exhaust gas is also applied to the direct injection engine.
The implementation and application of Euro 5 emission standards in Vietnam will significantly contribute to eliminating vehicles that generate a lot of harmful emissions and pollute the air environment. At the same time, it is possible to produce or import new vehicles that run on cleaner fuels, helping to improve pollution and protect the environment.
