ABSTRACT
The engine bench test system is an essential approach to measure dynamic properties, economic performance, and reliability of the engine, and the automaticity and accuracy directly influences the exactitude of acquired and analyzed data. The engine bench test and control system are based on virtual instruments. The hardware of this system consists of sensors, which are used to obtain engine information of parameters such as rotation, temperature, and vibration, as well as of the signal conditioning module and data acquisition card, which match the sensors properly. Data processing and interface displaying software are programmed based on Lab Windows/CVI. The results show that the engine general performance test is carried out on the system and automatization is realized in data measurement, registration, and management.
