Development of a modernized impeller of a liquid pump for a truck cooling system

The article presents the development of a technologically advanced and inexpensive wheel vane pump for a truck engine cooling system. To accomplish this task, a numerical simulation of a regular impeller was carried out, and its characteristics were also obtained from the experimental stand. The verification of the computational model of a regular impeller is carried out. Then, in the existing dimensions, the design of the open impeller wheel was developed and its numerical simulation was carried out. The developed impeller works quite efficiently and at the highest values of efficiency. The efficiency of the pump during operation as part of the engine is maximum and equal to 0.552—0.579. The maximum pump efficiency is 0.579 and is achieved at the highest speeds with a wheel speed of 4548 rpm and a flow rate of 655 l/min.

Dynamic Load Test Based Data-Logger Turbo matching of B60J67 A58N70 and A58N75 Turbochargers for Tata 497 TCIC-BS III Engine - An Investigation

Turbocharger matching is a process of matching a turbocharger to the desired engine. Many methods were proposed to perform the best match but they failed at certain cases. Due to inherent character of centrifugal compressor less torque develops poor transient response compared to naturally aspired engine. The mismatch of turbocharger will lead to poor performance. This research adapts, on road test based data logger turbomatching. In this investigation the matching performances of different turbochargers with a TATA truck engine was analysed. Five different routes included were for testing the match performance, the speed was varied at four levels from minimum to maximum, the load on the vehicle was varied at 6 levels from no load to full load. All the observations were superimposed on the respective compressor map and the match performance was analysed and the best match was suggested.
