ACTUATING AND DATA ACQUISITION SYSTEMS USED IN CASE OF A TEST BENCH FOR TESTING ENGINE VARIABLE VALVE TIMING SYSTEM ELECTROVALVES

Abstract

The article presents the actuating and data acquisition systems used in case of a test bench designed and manufactured for studying contaminantion behaviour of some components of the vehicle engine variable valve timing system. Particulary, a concept integrates all the equipment and software used for the test bench were in detail presented. This concept system includes different type of sensors, data acquisition board with dedicated software programs, integrated board for actuating electro-valves tested particulary developed, and many other devices. In conclusion, all these were used from the necessity of studying the contaminants behaviour of the electrovalves of the Vario Cam Plus system, with the eye of a future improvement, because a proper function of these components means optimal behaviour of the vehicle engine, like fuel consumption reduction, polluant emission decrease, and engine performance improvement.
