Abstract
The present invention is a second kind of High Efficiency Integrated Heat Engine, or HEIHE-2 for short. HEIHE-2 is a reciprocal combustion engine integrated with both compound cycle and combined cycle. HEIHE-2 comprises triple compound cylinder structure, with the first cylinder and the second cylinder being the primary combustion and/or expansion cylinders; and the third cylinder being the secondary combustion and/or expansion cylinder. Power strokes driven by expansions of different working fluids such as air-fuel combustion products, steam and compressed air, are integrated into one engine block. Triple cylinder structure provides compound expansions of three (3) different fluids as to recover the energies that would be lost with the exhaust fluids or during braking. All of these make HEIHE-2 work around four (4) periods with six (6) different operation strokes. All four (4) working periods contain four (4) different power strokes but only two (2) of them consume the fuel. Thus the fuel conversion efficiency could be greatly increased, or even be doubled comparing with the conventional internal combustion engine (ICE).
