Latest Patents

Yuanfan Zhao's latest patents include the High Efficiency Integrated Heat Engine-2 (HEIHE-2) and the High Efficiency Integrated Heat Engine (HEIHE). The HEIHE-2 is a reciprocal combustion engine that integrates both compound and combined cycles. It features a triple compound cylinder structure, where the first two cylinders serve as primary combustion and expansion cylinders, while the third cylinder acts as a secondary combustion and expansion cylinder. This innovative design allows for power strokes driven by various working fluids, such as air-fuel combustion products, steam, and compressed air, all within a single engine block. The HEIHE-2 operates through four distinct periods with six different operation strokes, significantly enhancing fuel conversion efficiency compared to conventional internal combustion engines.

The original HEIHE patent also presents a similar concept but utilizes a twin compound cylinder structure. In this design, the first cylinder is the primary combustion and expansion cylinder, while the second serves as the secondary combustion and expansion cylinder. The HEIHE operates through six periods with twelve operation strokes, achieving improved fuel efficiency by minimizing fuel consumption during its power strokes.
