영문 초록

For the improvement of an engine performance, it is required to understand the effect of various controlling parameters. To accomplish this goal, precise measurement of the experimental data is essential. Recently, with the progress in micro-electronic technology, microprocessors are begun to used to improve the accuracy as well as the efficiency of the experimental measurements. In this research, an efficient and accurate A/D converter along with a high-speed data acquisition system is developed to analyze the characteristics of internal combustion engines. Corresponding softwares are also developed. The performance of the developed data acquisition system is demonstrated by measuring (1) the pressure variations in cylinder, (2) needle valve lift in fuel injection valve and (3) the pressure variations in intake pipe. The accuracy and efficiency of the developed system are confirmed. From the analysis of experimental data several suggestions are made to improve the volumetric efficiency of the internal combustion engines.
