Turbo-matching of A58N70 Turbo-charger for a Commercial Vehicle Engine

Abstract

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.
