Experimentation for Evaluation of Real Driving Emission Test Routes in India for LDVs 2019-26-0150
With introduction of Bharat Stage VI (BS VI) norms from 1st April 2020, automotive industry will observe one of most stringent emission reform in India. This step is in the direction to bring Indian emission regulation 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) and Heavy Duty Vehicles (HDVs) in the city of Pune, Mumbai, and Bangalore. The collected data was post processed using CO2 and work based Moving Average Window (MAW) method for LDV and HDV respectively. For LDVs data is analysed and presented based on the boundary conditions (speed, trip distance, trip share, trip duration, ambient temperature, altitude etc.), vehicle trip dynamics (Relative Positive Acceleration, and v*apos), trip completeness and trip normality. For HDVs data is analysed and presented based on the boundary conditions (speed, trip distance, trip share, trip duration, ambient temperature, altitude etc.), and trip normality. The analysis of RDE trials also gave understanding and insights to possible modifications required for Indian RDE regulation.
