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

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.
