【摘要】 针对S195柴油机的动力性经济较差的现状,文章分析了影响S195柴油机技术状态的主要参数,并对这些参数进行了大量的室内台架试验,从而找到了S195柴油机在不同位术状态和使用工况下影响耗油率的主次参数及这些参数影响耗油率的规律,并且,作者通过优化计算,得出了参数的最佳组合.经过对所得结果的实验验证,发现效果十分显著,在已经过维护保养的机器上进行优化调整,可以使功率提高 0.18～0.97kW,耗油率下降11.2～29.5g/kW·h.更多还原

【Abstract】 According to the condition that the technical state of S195 Type Diesel Engine in use isrelatively poor in general, optimal adjustment technology of the engine in use was developed to recover its power and reduce its specific fuel consumption- In this paper, the main factors influencing the technical state of the engine were obtained through analysis. On the basis of it, enginebed tests and analysis were carried out, the order of the effect, suitable range and interaction of parameters on specific fuel consumption in different techical states and work conditions of the engine were obtained. By means of optimization technique the optimum parameters for different technical state and work conditions of the engine were provided. For verifying the results of optimal adjustment, a comparative test was conducted and satisfactory result had been obtained.更多还原
