“…Some of the system designs were made to manage this problem. They are: adopting the sequential system [8], incorporate the limiting fuel system, reducing the inertia, improvements in bearing, modification on aerodynamics [9], establishing electrically supported turbocharger [10], the use of positive displacement charger i.e., secondary charging system and use of either electric compressor or positive displacement charger with turbocharger [10],[11] facilitating the geometrical variation on the compressor and turbine [12], adopting the twin turbo system [13], and dual stage system [14]. It is noticed that the transient condition is always worst with the engine which adopted single stage turbo charger.…”

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.

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.

“…However, the turbine working environment is relatively poor; especially the impeller is vulnerable to damage. Therefore, we need to understand the flow field characteristics inside the turbine to improve turbine efficiency and improve turbocharger performance [3,4]. Due to the extremely complex internal and external dimensions of the turbocharger, it is difficult to measure and improve the internal turbulence flow field distribution of the turbocharger by means of experimental verification, and this method requires a lot of manpower and material resources, it is difficult to ensure the accuracy of the data.…”

Abstract. This paper is based on the theory of computational fluid dynamics (CFD), the turbulent flow field of turbocharger is numerically simulated by fluid-solid coupling method, and the flow field cloud of the turbine is obtained. By comparing the calculated efficiency and experimental values, we can see that the error between the two does not exceed 5%. The simulation accuracy is verified. Through the improvement of the turbine blade through the three-dimensional modeling software, the modified turbine is re-simulated. The results show that the improved turbo expansion ratio is improved by 0.05 and the turbine efficiency is improved by 4.55%.
