Turbo-charger is castigated as the performance maker for commercial vehicle especially during the operating conditions at Maximum torque and higher loads. Complication lies in Turbo-matching and carried out by many methods. Automotive manufacturer added many components in supplier chain. This investigation adopts test based methodological approach to perform such turbo-matching. The simulation based method is used to obtain the initial operating conditions at various engine speeds by using manufacturer data. The same verified by Data-logger method through experimental observation of operating conditions at various routes namely rough road, highway and slope up at various specified speed also. Compressor map is used to depict the performance and evaluation of matching. The appropriate turbocharger is suggested.
Key Words: Turbocharger, Compressor, turbo-matching, Choke, Surge, Data-logger, Simulation.
