Main Features of Engines Used on Indian Two-Wheelers

Main Features, Fuels and Uses of Indian Three-Wheelers

Progression of Indian Emission Standards for 2 & 3-Wheelers All limit values for mass emissions in g/km under Indian Driving Cycle

Known, Potential and Emerging Technologies for 2&3–Wheelers

Expected Time-Line for Evolution of Engine Technologies for 2-Wheelers

Changes in Technology Choice Resulting from Consumer Preferences & Emission Standards The proportions of 2-stroke and 4-stroke have been calculated based on a study of the sales figures of various companies obtained from Society of Indian Automobile Manufacturers (SIAM) and from the knowledge of the models produced by manufacturers

Methodology for the Estimation of Fuel Consumption and CO 2 Emissions – 1/2 (a) Baseline fuel consumption of current technologies is average of “Type Approval Test” results of several models published by the Automotive Research Association of India (ARAI)*. ARAI calculates fuel consumption in km/litre using the ‘carbon balance method’ from measured exhaust emission levels under “Indian Driving Cycle” run on a chassis dynamometer (b) The baseline data for average CO 2 emissions (tail pipe only) of each category of vehicle has also been determined from the same source of data * Source: Bhanot B, Kulkarni U.,”Indian Auto Emission Profile”, Symposium on International Vehicle Technology, Automotive Research Association of India, 2001

Methodology for the Estimation of Fuel Consumption and CO 2 Emissions – 2/2 (c ) The fuel consumption of new Internal Combustion Engine (ICE) technologies based on the indications in literature. (d)All the fuel consumption values converted to MJ/km by using appropriate values of density and Lower Heating Values of the respective fuels. (e) CO 2 emissions of new ICE technologies derived from the fuel consumption by establishing a relationship between fuel consumption and CO 2 emissions

Fuel Consumption Trends of Different Categories of 2 & 3-Wheelers Resulting from Various ICE Technologies

Progressive Reduction in Fuel Consumption of 2-Wheelers Resulting from Improved ICE Technologies

Progressive Reduction in CO 2 Emission of 2-Wheelers Resulting from Improved ICE Technologies

Progressive Reduction in Fuel Consumption of 3-Wheelers Resulting from Improved ICE Technologies and CNG

Progressive Reduction in CO 2 Emission of 3-Wheelers Resulting from Improved ICE Technologies and CNG

Methodology for the Estimation of Fuel Consumption and CO 2 Emissions of EV and Hybrid EV ( a) The energy consumption (in MJ/km) of battery operated electric vehicle was considered to be 30% of the energy consumption of the basic ICE. This is based on the reported energy consumption of 0.06 kWh/km of the Bajaj three wheeler(1). (b) The energy consumption of hybrid electric vehicles has been considered as 85% of that of the EV based on literature for both the hybrid and electric four wheelers (2). (c) CO 2 emission of EV and Hybrid EV based on ratio of the fuel consumption of the hybrid and corresponding basic ICE used in the category of vehicle Sources (1) Berry R.K., Schweitzer Samuel, Basu Tapan, Bedewi Nabih, Vincent Daniel, Dhungana Atulya, “Indian Zero Emission Transportation Program – a driving force for change”, International Symposium on Automotive Electronics and Alternative Energy Vehicles, Indian Institute of Technology, Kanpur, November (2) Ybema J.R., Lako P., Gielen D.J., Oosterheert R.J., Kram T., “Prospects For Energy Technologies in the Netherlands, Volume 2, Technology characterizations and technology results”, ECN, August 1995

Conclusions 1/2 There is a rapid increase in the number of motor vehicles in India, the population being dominated by two wheelers, yet, vehicle penetration is among the lowest in the world Progressively stringent emission standards and customer demand for fuel economy resulted in manufacturers adopting new technologies to reduce emissions and fuel consumption that have also resulted in reduction in CO 2 emissions

Conclusions 2/2 Adoption of more stringent standards for 2&3 wheelers in the coming years is expected to lead to the adoption of newer technologies which are also expected to bring about further reductions in fuel consumption and CO 2 emissions. CO 2 contribution of the Indian transport sector is estimated to be 15% of the total ( ). While the rapidly increasing population of vehicles may lead to an increase in this, the progressively reducing levels of CO 2 emissions may have a compensating effect.
