| 20150337723 | MOMENTUM DRIVEN FUEL INJECTION OF STEAM AND FUEL VAPOR FOR COMPRESSION IGNITION ENGINES - The present invention directly affects two primary limitations of diesel fuel: poor vaporization and ease of auto-ignition.

The apparatus increases an amount of fuel supplied to the engine as the detected alcohol concentration becomes higher. The apparatus increases the amount of fuel as the engine temperature becomes lower and as the alcohol concentration becomes higher. The apparatus feed-back corrects the amount of fuel by using a correction value such that an actual air-fuel ratio becomes a theoretical air fuel ratio. The apparatus determines that water is mixed with fuel when the correction value during a cold operational state indicates leaner than the lean value of the correction value used during a warm operational state. The apparatus reduces the increased amount of fuel when water is mixed with fuel. | 03-04-2010 |
| 20090056670 | HIGH EFFICIENCY INTEGRATED HEAT ENGINE-2 (HEIHE-2) - 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). | 03-05-2009 |
| 20090217904 | CRANKLESS RECIPROCATING STEAM ENGINE - We present a high-efficiency crankless reciprocating steam engine that loses only a small amount of energy when the rectilinear motion of its piston is changed into the rotary motion of its driveshaft. The present invention continuously rotates a valve in one direction while alternately introducing steam into two piston housing chambers to generate the rotary force of the driveshaft. Therefore, engine efficiency is greatly increased because the inertial force losses in the valve are much smaller compared to the case when the valve rotation stops or changes direction. | 09-03-2009 |

A combination of large compression ratios combustion temperature optimization and management, instantaneous and complete combustion at TDC, followed by a rapid and long expansion stroke using tailored control of piston movement provide the means to achieve such high efficiencies. | 03-07-2013 |
