【摘要】 为了提高车用发动机运行过程经济性,利用函数链神经网络对曲轴转角值所对应的气缸压力数据进行了拟合,得到了基于函数链神经网络的车用发动机气缸压力数据采集系统.应用结果表明,该气缸压力数据采集系统能有效地消除采集数据时各种干扰的存在,使得采集到的数据偏离其真实数值的程度较小.这对于改善车用发动机的燃烧状况,提高经济性能具有重要的意义.更多还原

【Abstract】 In order to improve the efficiency of vehicle engine,a data acquisition system of the cylinder pressure in vehicle engine could be gotten when a fitting formula about cylinder pressure based on different signal of crank speed was established by using function chain neural network.The testing results showed that the system realized the distinct functions,such as acquisition of cylinder pressure data by eliminating effectively the influence from some noises This was useful for improving the combustion condition of vehicle engine with multi-cylinder and increasing the thermal economy.更多还原
