中文摘要:基于内燃机的工作特点,比较理论循环的三种加热方式,证明了温压约束下等压加热循环性能最优。通过优化理论循环,提出了等压换热理想循环,由此推导出温压约束下内燃机循环净功和热效率界限的计算公式,并给出了获得最大循环净功的条件,以及相应热效率与卡诺循环热效率的关系。
外文摘要:After three heating forms of theoretical cycle were compared, in accordance with the working specialities of internal combustion engines, it was confirmed that performance of the constant pressure heating cycle was optimal within temperature and pressure restraints. By optimizing theoretical cycle, constant pressure heat exchange ideal cycle was proposed. According to the ideal cycle, limit formulas of cycle net work and thermal efficiency for internal combustion engines within the restraints were derived. The condition for the maximum cycle net work was given, and the relation between the thermal efficiency at the work and the Carnot cycle thermal efficiency was given.
