Application of Interpolation Method on Transient Speed Measurement of Diesel Engine

Period measurement method and general data collection equipment was employed to measure the rotation speed of diesel in transient operation status. Aimed at the problem of low sample rate leading to low measurement distinguish rate of transient speed, interpolation method was present. Interpolation was used to analyze original data collected by low sample rate to improve sample rate or acquired precise zero points. This method improves the measuring accuracy marked.
