Monetary support was provided by the Greenpeace India Society just for this study. Thanks are because of Mr. L. Soumyabrata of Greenpeace India and Mr. Manoj Sharma of IIT Kanpur intended for providing aid in collection of specialized data pertaining to Indian automobiles.


Vehicle gas efficiency (FE) rules are staying implemented everywhere to conserve energy and for lowering of carbon dioxide exhausts. In the USA, fleet average FE standards were set starting from the year 1978, but these remained at standstill after the season 1992 until the year june 2006 when the criteria for light trucks were upgraded. The new standards intended for the light vans are based on motor vehicle size defined in terms of ‘footprint'. The new ALL OF US standards intended for cars are expected to be finished soon. The European Union standards derive from fleet averaged carbon dioxide exhausts while the Asia standards derive from vehicle weight. The EU has already established the standards suitable for the model year 2012 and Japan for the entire year 2015. America and The japanese standards are mandatory. The EU criteria are voluntary in characteristics so far nevertheless become necessary from the year 2012. Main fuel economy improvement technologies being pursued and implemented in modern gasoline vehicles will be; multi-valve machines with vvt and lift up, gasoline direct injection (GDI) engines with stratified demand lean blend or stoichiometric mixture, engine undersizing and turbocharging, and cylinder deactivation for 6- and 8-cylinder engines. In the diesel voyager vehicles, the IDI diesel-powered engine continues to be phased out nearly completely in Europe. It is replaced by the high speed direct injection (HSDI) engine that has usually 4-valves/cylinder, employs common rail diesel powered injection (CRDI) system and is also turbocharged with intercooling. Various other new technology like nonproductive stop-start systems, integrated starter- generators are being integrated. New part designs intended for reduction of engine chaffing are staying developed and low rubbing lubricants are utilized. Power transmission systems are using more...
