柴油机燃料燃烧与汽油机相反,它的特征是空气过量系数始终大于1,因此可以看成是完全燃烧。在势力学研究中可将工作气体视为理想气体。由于气缸充量和气体成分的变化与燃料的转换有关,因而为了确定燃烧规律的数学公式须用三个微分方程的方程组来描述。计算方法首先受理论压力曲线的检验。对于测得的压力——时间示功图,为了减小偶然误差须要进行光顺,最后对死点误差和压力误差的影响进行了研究。
Diesel fuel combustion In contrast to gasoline engines, it is characterized by an air excess coefficient that is always greater than 1 and therefore can be considered as complete combustion. Working gas can be regarded as the ideal gas in the research of force science. Since changes in cylinder charge and gas composition are related to the conversion of fuel, the mathematical formula used to determine the combustion law must be described by a system of equations of three differential equations. The calculation method is first tested by the theoretical pressure curve. For the measured pressure-time dynamometer, smoothing is required to reduce the chance error, and finally the influence of dead point error and pressure error is studied.
