3 kW 斯特林发动机 NS03T 是一种具有独特 V 形气缸布置的两活塞型发动机，专为家用空调热泵系统而开发。通过采用这种气缸布置和精心设计的热交换器系统，获得了大约 50% 的指示效率。本文介绍了 1984 年型号 NS03T 发动机的规格和改进，该发动机是 NS03T 发动机中第一台发动机，具有最高的效率和性能。 NS03T 发动机的指示效率是通过使用实验数据和数学模型、斯特林发动机热力学和机械分析的分析数据来呈现的。此外，通过能够从发动机运行数据得出准确的再生器损失的方法来分析再生器损失。结果表明，热交换器的设计对于高效发动机非常重要。
A 3-kW Stirling engine, NS03T, which is a two-piston type with a unique V-shape cylinder arrangement, was developed for a household heat-pump system for air conditioning. By adopting this cylinder arrangement and a well-designed heat exchanger system, an approximate 50% indicated efficiency was obtained. In this paper the specifications and modifications of the 1984-year model NS03T engine are presented, which was the first engine and had the highest efficiency and performance among the NS03T engines. The indicated efficiency of the NS03T engine is presented by using experimental data and analyzed data by a mathematical model, Stirling Engine Thermodynamic and Mechanical Analysis. Also, the regenerator losses are analyzed by a method that is able to derive accurate regenerator loss from engine operating data. The results show that the design of the heat exchanger is important for high-efficiency engines.
