In this paper, the combustion simulation considered of two-cycle, side spray for slow speed diesel engines are presented. In the simulative calculation, an attempt is made to transform an existing simulation code to apply it to two-cycle, side spray diesel engine design. The model has, up to now, proved to give reliable pre-dictions of both engine performances and emissions for high-speed diesel engines, but some modifications have been made in order to simulate two-cycle, side spray for slow speed diesel engine. By comparing calculated results with the experimental results, it was revealed that the modified model predicts with very good accuracy engine performance. Of course, more validation is required for the model, especially concerning the prediction of pollutant emission.
Along with the evolution of electronics, sensors are widely used in vessels and vehicles making operations safe and comfortable. Different from other electronic components, sensors are, however, used in harsh environments and sometimes conventional testing is not sufficient enough to evaluate their reliability. This report presents a study where FTA and existing information from design, production and fields are effectively used to find factors affecting the failure quickly, effectively and accurately without redundant experiments and analysis. In addition, newly developed FMFC, and comprehensive recurrence experiment methods are proposed to find correct failure mechanism. Through these processes, we expect to develop accelerated testing with smaller yet accurate experiments. Finally, we verified the effects of the aforementioned method by successfully applying it to the thermistor temperature sensors.
