Turbocharger is a charge boosterfor internal combustion engines to ensure best engine performance at all speedsand road conditions especially at the higher load. Random selection of Turbocharger may causeill effect like surge and choke in the breathing requirements of the Engine.Appropriate match or selection of the turbocharger is a tedious task. Butperfect match gives more distinguished advantages on increasing the performanceof the engine. This study focuses to match the turbocharger with engine throughsimulation and on road test. The objective of this work is to find matchingappropriateness of turbochargers with trim 67 (B60J67), trim 68 (B60J68), trim70 (A58N70) and trim 75 (A58N75) for the TATA 497 TCIC -BS III engine. Indata-logger method the road routes like Rough road, highway, City Drive, Slopeup and slope down were considered for evaluation. The operating conditions withspeeds, routes and simulated outputs were compared with the help of compressormap.
