本文论述了确定示功图上止点位置的热力学方法——多变指数法,对2135柴油机倒拖气电示功图的计算结果与实测的活塞动态换气上止点进行比较,表明用本文的方法来确定示功图上止点位置是可行的.
This paper discusses the thermodynamic method of determining the top dead center position of the dynamometer - the variable index method. Comparing the calculated results of the inverted pneumatic dynamometer of the 2135 diesel with the measured dynamic top-pumped piston points, Method to determine the TDC TDC position is feasible.
