Turbocharger is a Charge booster, which helps the automobiles, especially at higher loads by providing best operating performance. The adaption of such turbocharger for the desired engine is a tedious job and requires intensive care. The mismatch may decrease the operating performance by occurrence of surge or choke in the flow of charge and may cause bearing oil leakage. As the turbochargers are now supplier supply, the simulation and data-logger matching methods are considered for evaluation. The matching performance is predicted by the simulation and the same was verified with data-logger method. This research aims to find the appropriateness of matching of A58N70 Turbo Charger for the TATA 497 TCIC -BS III engine. The datalogger matching was carried out with various routes like Rough Road, Highway, City Drive, slope up and slope down were considered in evaluating matching performance. The results compared with use of compressor map.

Turbocharger is considered as Charge booster of IC Engine, especially at higher load. Negative compressor performance like Surge and Choke occurs by improper turbo-matching. Turbo-matching is a tedious task and requires extreme care. It is one time job for an engine kind and expensive. This research articles focuses on evaluation of appropriateness in turbo-matching of B60J67, B60J68 and A58N75 turbochargers for TATA 497 TCIC -BS III engine. The simulation and datalogger method used obtaining the operating conditions. The road conditions like rough, city drive, highway, slope and slope down were included for on road test (data Logger method). The appropriateness evaluated with use of compressor map.

Nowadays turbo-chargers are preferred for commercial vehicle especially to ensure the good operating conditions at higher loads. Turbo-matching is a complex task and carried out by many methods. Recent manufacturing trend added many components in supplier chain. This piece of investigation adopts test based methodologies to perform such matching. The simulation is used to predict the operating conditions at various speeds. The same verified with data-logger method which is like on road test. The routes preferred for evaluating the various routes namely rough road, highway matching performance are: Rough Road, Highway, City Derive, slope up and slope down. The compressor map used for analyse the appropriateness of matching by methods and suggesting the appropriate turbocharger.

The Turbocharger is a charge booster for internal combustion engines to ensure best engine performance at all speeds and road conditions especially at the higher load.  Random selection of turbocharger may lead to negative effects like surge and choke in the breathing of the engine. Appropriate selection or match of the turbocharger (Turbomatching) is a tedious task and expensive. But perfect match gives many distinguished advantages and it is a one time task per the engine kind. This study focuses to match the turbocharger to desired engine by simulation and on road test. The objective of work is to find the appropriateness of matching of turbochargers with trim 67 (B60J67), trim 68 (B60J68),  trim 70 (A58N70) and trim 72 (A58N72) for the TATA 497 TCIC -BS III engine. In the road-test (data-logger method) the road routes like highway and slope up were considered for evaluation. The operating conditions with respect various speeds, routes and simulated outputs were compared with the help of compressor map.
