摘要：The small power diesel engines are most demanding product in Indian market for power genset andTractor applications. The basic requirements of the end user in off-road market are good response, transientperformance, better low speed torque, better fuel efficiency and smooth operation of the engine. Additionalrequirements needed to sustain the market are downsizing of the engine, higher power to weight ratio and increased lifeof the engine.Turbo charging applied to off road diesel engines is a promising solution for enhancing rated power, low end torque,transient performance, better low-speed torque, optimized fuel efficiency and downsizing diesel engines. A trade-off isrequired to match some conflicting issues, i.e. overall dimensions, cost, emissions control and performance in order tosustain. Future Diesel engine emission standards will further restrict vehicle emissions, particularly nitrogen oxides.In the present work, reference is made to 1.29L, 2 cylinder in-line diesel engine for genset application and itsconversion to off-road application satisfying all the needs of the market is attempted by the application of turbocharging. The development methodology adopted to achieve high pressure ratio turbo charging is discussed along withoperating limitations. Turbo charging the internal combustion engine has become a key point in both reduction ofpollutant emissions and improvement in engine performance. The matching between turbocharger and engine isdifficult in two cylinder engines because of the highly unsteady flow and off-design conditions the turbocharger workswith.An elaborate study is done on this 2 cylinder compact diesel engine for the optimization of performance with changesin nozzle geometry, static injection timing, change in injector end pressure, nozzle tip protrusion and exhaust gasrecirculation to achieve TREM IIIA norms in naturally aspired engine. The emission values are documented in thepresent work and further the behavior of the engine and the ease of meeting emission norms by turbo charging andintercooling is also done to clearly indicate the need of supercharging in off-highway applications
