摘要： A highly efficient regenerative reciprocating internal combustion engine is disclosed. The regenerator captures the unutilized heat normally expelled with the exhaust products of such an engine and transfers it to fresh working fluid at the appropriate time in the next engine operating cycle to reduce the quantity of fuel which must be burned, resulting in an increase in engine efficiency. This is accomplished through the use of a permeable, movable heat exchanger located between the piston and the cylinder head. This regenerative technique can be applied to both two and four stroke Diesel cycle and Otto cycle engines. It can also be employed in ported (i.e. valveless) engines. The hot combustion region can be located between the cylinder head and the regenerator or between the piston and the regenerator. These regenerative devices and processes greatly improve the thermal efficiency of conventional internal combustion engines, while providing power outputs similar to conventional engines of the same displacement, greatly reducing hydrocarbon and carbon monoxide emissions, and utilizing much the same hardware. In addition, the regenerative internal combustion engine places reduced heat loads on engine components, is operable at lower peak temperatures (with thermal efficiencies and power still comparable to conventional engines), and is better able to utilize high temperature materials which can reduce heat loss to engine cooling systems.

摘要翻译： 公开了一种高效再生往复内燃机。 再生器捕获通常用这种发动机的排气产物排出的未利用的热量，并在下一个发动机运行循环中的适当时间将其转移到新鲜的工作流体中，以减少必须燃烧的燃料量，从而导致发动机的增加 效率。 这通过使用位于活塞和气缸盖之间的可渗透的可移动热交换器来实现。 这种再生技术可以应用于二冲程和四冲程柴油循环和奥托循环发动机。 它也可用于移动（即无阀）发动机。 热燃烧区域可以位于气缸盖和再生器之间，或位于活塞和再生器之间。 这些再生设备和工艺大大提高了常规内燃机的热效率，同时提供了类似于相同排量的传统发动机的功率输出，大大减少了碳氢化合物和一氧化碳排放，并且使用了相同的硬件。 另外，再生内燃机将发动机部件的热负荷降低，可以在较低的峰值温度（热效率和功率仍然与传统发动机相当）下工作，并且能够更好地利用可以减少热损失的高温材料 发动机冷却系统。

摘要： An improved, reciprocating internal combustion engine is disclosed herein. This engine consists of multiple cylinders, each closed by a cylinder head and containing a piston which is connected to a power output shaft. Each cylinder has means for the intake and exhaust of working fluid. It also contains a movable, thermal regenerator, an alternating flow heat exchanger, and means to move this regenerator. Finally, means are provided for the introduction of fuel into the cylinder. The regenerated, internal combustion, reciprocating engine and several variations on it disclosed herein are substantially different from prior art and provide critical improvements over that prior art. These improvements include different and superior heating and cooling strokes.

摘要： An improved, internal combustion, reciprocating engine employs thermal regeneration to improve its efficiency and power. Regeneration is accomplished through the use of an alternating flow heat exchanger. In one embodiment the engine consists of one or more cylinders containing a pair of opposed pistons, a hot piston and a cold piston separated by a stationary regenerator. The engine is equipped with means to introduce gaseous or liquid fuel into said hot volume, means to introduce fresh working fluid and means to remove exhaust gases from the cold volume. In one embodiment one or more exhaust ports permitting the flow of exhaust fluid out of the cylinder are located between a cold piston and the thermal regenerator and one or more intake ports permitting the flow of fresh working fluid into the cylinder are located between the cold piston and the exhaust ports. The engine can provide greater expansion than compression and can provide critical and substantial improvements over previous engines.
