RDE testing of small Motorcycle in Indian Road Conditions and study the impact of instrumentation on emission and fuel economy

This paper presents the results of real-world driving emissions and fuel economy measurements for two-wheelers in India using a state-of-the-art FTIR PEMS technology. The study aimed to characterize the emissions profiles of a small motorcycle under typical Indian driving conditions, including congested urban traffic and highway driving. This is the continuation of the study conducted previously on bigger motorcycle using gas analyzer [ JSAE 20179041 / SAE 2017-32-0041][1], with necessary adaptations to suit the specific conditions of Indian roads and traffic. Key parameters such as NOx, CO, CO2 and Fuel consumption were measured during real-world driving cycles and comparison is done with standard WMTC emission testing cycle. The findings of this study provide valuable insights into the actual on-road emissions of two-wheelers in India, which can be used to inform regulatory policies, develop more accurate emission models, and guide the development of cleaner and more efficient two-wheeler technologies. Key Considerations: • Specifics of Indian Driving Conditions: Emphasize the unique challenges posed by Indian traffic, such as stop-and-go traffic, frequent idling, and high ambient temperatures. • Data Analysis and Interpretation: Discuss how the data was analyzed and the statistical methods used to assess the significance of the findings. • Comparison with Laboratory Tests: Compare the real-world emission results with those obtained from laboratory tests to assess the accuracy of current regulatory testing procedures. • Policy Implications: Discuss the implications of the findings for future emission regulations and the development of cleaner two-wheeler technologies in India. This abstract provides a concise overview of the research and highlights the key findings and their significance. Study is also conducted and compiled to show the effect of measurement devices on the actual emissions and fuel economy of the vehicle tested in standard WMTC emission testing cycle inside the lab conditions.
