The regenerative engine is a new concept of internal combustion engine in which part of the energy of the exhaust gases is recovered in a porous regenerator to be used in the next cycle. As a result, the thermodynamic cycle in the engine is radically changed. A computational model, including fluid friction as well as thermodynamic variables, has shown indicated efficiencies in excess of 40 percent for wide ranges of fuel/air mixture ratios, speeds, loads, and design parameters. This engine also promises a reduction of pollutant emissions and a higher power density through the elimination of knock. It is proposed to test experimentally this cycle in order to check the appropriateness of the model and the practical potential of the new cycle. Conventional engine tests (load, speed, fuel consumption, and emissions) will be performed over a prototype engine composed of two single-cylinder engines. In this engine, one cylinder acts as a compressor and the other as an expander with a variable phase difference between them. Flow is controlled by a series of poppet valves. Experimental indicated cycles will be obtained for comparison with the predictions of the model and its further improvement. Heat transfer and combustion sub-models will be added as experimental data become available.

再生式发动机是一种新概念的内燃机，其中废气的部分能量在多孔再生器中被回收以用于下一个循环。 结果，发动机中的热力循环发生了根本性的变化。 包括流体摩擦和热力学变量在内的计算模型显示，对于各种燃料/空气混合比、速度、负载和设计参数，效率超过 40%。 该发动机还承诺通过消除爆震来减少污染物排放并提高功率密度。 建议对该循环进行实验测试，以检查模型的适当性和新循环的实际潜力。 传统的发动机测试（负载、速度、油耗和排放）将在由两台单缸发动机组成的原型发动机上进行。 在该发动机中，一个气缸充当压缩机，另一个气缸充当膨胀机，它们之间的相位差可变。 流量由一系列提升阀控制。 将获得实验指示的循环，以与模型的预测进行比较并进一步改进。 当实验数据可用时，将添加传热和燃烧子模型。
