摘要
针对柴油机热力循环的特点,提出了一种柴油机火用平衡计算方法,该方法可以计算出工质与冷却介质之间由于温差传热而引起的火用损失。计算结果表明,减少排气损失和工质与冷却水的温差传热损失、改善燃料燃烧过程是提高内燃机可用能利用率的主要途径。
This paper put forward an exergy equilibrium calculation method of diesel engine, in which the exergy losses between the working substance and the cooling agent because of difference in temperature heat transmission can be calculated, according the features of engine cycle of diesel engine. The calculation results show that the major channels of improving exergy efficiency of internal combustion engine are to reduce exhaust losses, reduce heat transmission losses and improve combustion of the fuel.
