Air pollution is a growing concern in India, and vehicular emissions are a significant contributor. In 2020, Indian government introduced the Bharat Stage 6 (BS6) norms to reduce automotive pollutants, and now, the second phase of these standards will be initiated from April 2023. The second phase of BS6 calls for the implementation of Real Driving Emission (RDE) norms, which aim to reduce the gap between laboratory emission values and real-world conditions. In this article, we will discuss everything you need to know about RDE norms. |
To understand RDE norms, it is essential to know what Bharat Stage Emission Norms are. Regulated by the Government of India, Bharat Stage Emission Norms are standards followed by automakers to control and regulate vehicular emissions. These aim to decrease the emission of gases like carbon dioxide (CO2), carbon monoxide (CO), Hydrocarbons, and Oxides of Nitrogen. RDE norms will come into effect from April 1st, 2023, and will require carmakers to test and measure pollutants emitted from their vehicles in a real-world driving scenario. This will be done by equipping the vehicles with a Portable Emissions Measurement System (PEMS). Car makers will need to use Selective Catalytic Reduction (SCR) systems in all diesel engines, which will reduce emissions of compounds such as nitrogen oxides (NOx) by converting pollutants into water, nitrogen, and minute amounts of carbon dioxide. |
Additionally, it is now mandatory to have an Onboard Diagnostic (OBD) system to inform vehicle owners/technicians how efficient different vehicle systems are. This OBD device will process readings from key components, including oxygen sensors and catalytic converters, to constantly check emissions levels. If the emissions exceed the desired parameters of the BS6 norms, an alert will be displayed to the driver, indicating that the vehicle needs to be serviced immediately. RDE norms are a significant development in the regulation of vehicular emissions in India. They will help reduce the gap between laboratory emission values and real-world conditions by measuring emissions in actual driving conditions. This will lead to cleaner air and better health for citizens. The second phase of the BS6 norms is a significant step towards a greener future for India. ease of use. |
