Investigation on Turbo-matching of Trim 67 Turbo-charger for a TATA Commercial Vehicle

Badal Dev Roy, Dr.R.Saravanan

Commercial vehicles and heavy vehicles require boosting of charge specifically at higher load. The turbocharger is such charge booster for automobile engines. Selection and matching are needed more attention and care. Because the mismatch of turbo charger for the desired engine may lead to disadvantages like surge and choke at engine air flow. Test based matching is adopted in this research. The initial matching performance is identified by the simulation method. The data-logger type matching method is used for confirming or validating the performance of matching. The objective of this research is to find the appropriateness of matching of B60J67 Turbo Charger for the TATA 497 TCIC -BS III engine. The compressor map is used for evaluating the solutions yielded both methods. The appropriateness was evaluated at various route conditions and presented.
