20100077988 | HYDROGEN-ONLY 6-STROKE ENGINE - There are no prospects for engines using hydrogen as fuel to be put to practical use due to significant small output, knocking, and backfire. An object of the present invention is to obtain a stable automobile engine at high drive that can be commercially put to practical use. A hydrogen-only 6-stroke engine realizing high output by 6-strokes for premixing two to seven atmospheric pressure or high pressure hydrogen and air at equivalent weight, spraying the pre-mixture into a cylinder cooled by filling the cylinder with cold air in advance, spraying, compressing, and exploding the mixture, discharging the mixture from a lower exhaust hole, and discharging remaining waste gas from an upper exhaust hole is proposed. | 04-01-2010 |
