Conventional measuring systems are not able to measure the exactly valve timing on real engines. Due to their requirements, the measurement procedure and consequently their accuracy there are variances, which have a great influence on the measurement results. For an improvement of the gas exchange and finally the engine characteristics it is necessary to develop a new way to get the real valve timing on operating engines. Therefore the University of Applied Sciences Hannover developed a new measurement system to detect the exactly valve timing on real operating engines. This method uses the valve and the valve seat ring as an electrical switch, which is reached by an insulation of these parts against each other. The result is that the valve timing, the length of the opening time, valve overlapping and effects like valve bouncing are able to detect by this new measurement system.
