摘要/Abstract

摘要： 为适应大功率特种车辆的需求，提出一种“涡轮活塞组合发动机”，由一台增压中冷柴油机和一台燃气轮机组合而成，具有柴油机单独工作、燃气轮机单独工作和柴燃联合工作3种模式，可根据车辆工况需要采用相应的一种模式工作。这种发动机理应综合柴油机与燃气轮机的优点，具有较高的热效率和功率密度。介绍了该组合发动机的构成，分析其3种工作模式的理论循环，推导相应的热效率和比功的计算公式；在所设定热力循环参数下，计算该组合发动机3种工作模式下的理论循环热效率和比功；搭建涡轮活塞组合发动机GT-Power仿真模型，对选定的由功率相近的某一柴油机和某一燃气轮机组成的涡轮活塞组合发动机进行了额定工况仿真计算。计算结果表明：涡轮活塞组合发动机可以综合柴油机和燃气轮机的特点，是一种值得进一步研究的新型发动机。

Abstract: The combined turbo piston engine is comprised of a diesel and a gas turbine, of which the three operating modes (single diesel mode, single gas turbine mode and the combined diesel and gas turbine mode) can be chosen according to the power need of the vehicle. The engine is assumed to have the advantages of diesel and gas turbine to acquire high thermal efficiency and high power density at the same time. The configuration of the combined engine is presented. The theoretical cyclic thermal efficiency and specific work of the engine under the three modes are studied. The formula of thermal efficiency and work weight ratio are deduced. According to the set parameters of the cycle, the thermal efficiency and work weight ratio of the three modes are calculated. A diesel engine and a gas turbine with similar rated power are chosen to make up the combined turbo piston engine. A simulation model of the combined engine is built in GT-Power, and the performances of the engine under the rated condition are calculated. The results show that the combined turbo piston engine can acquire high thermal efficiency and high power density.
