With introduction of Bharat Stage VI (BS VI) norms from 1st April 2020, automotive industry will observe one of most stringent Indian emission regulation implementation in line with International standards. The Bharat Stage VI (BS VI) regulation also mandates for Real Driving Emission (RDE) measurement from 1st April 2020 for data collection and subsequently establishment of RDE compliance Factor (CF) by 1st April 2023. Indian RDE test procedure will be largely based on European RDE with minor changes in terms of climatic conditions, traffic pattern, speed limit, topography, and vehicle population. For performing a successful RDE trial one of the most critical part is selection of a route on which all RDE boundary conditions can be met. This technical paper summarizes the outcome of RDE experiments carried out on Light Duty Vehicles (LDV) in the city of Pune, Mumbai, and Bangalore. The collected data was post processed using CO2 based Moving Average Window (MAW) method.
