Marine Diesel Engine Turbochargers On Test Benches - Sponsored Whitepaper

Delphin TopMessage Data Acquisition System

CAS DataLoggers recently provided the data acquisition solution for one of the world’s leading manufacturers of large diesel engines, turbochargers and complete drive systems. The company specialized in manufacturing diesel engines for shipping, power generation, and heavy road and rail vehicles with power ranges from 116 to 9000kW. Turbocharger performance determined overall engine performance, fuel consumption, and emissions, and were regularly tested using test benches where they were subjected to high levels of thermal and mechanical stress as well as exposure to temperatures of up to 750ºC (1382ºF) and a 5.0 pressure ratio. These test benches were designed to test the most critical areas and to optimize the robustness, efficiency and operation of the components, and could rotate the turbochargers as rapidly as 90,000 rpm. Given the complexity of these tests, plant managers began to see the need for a sophisticated data acquisition system offering highly accurate measurements, fast signal processing and easy configurability. The customer was also considering integrating more advanced test scenarios utilizing additional inputs in the near future, and therefore a modular system was required to enable management to upgrade the system easily with more input and output channels whenever needed.
