20100300416 | INTERNAL COMBUSTION ENGINE AND METHOD FOR CONTROLLING THE INTERNAL COMBUSTION ENGINE - During starting of an engine that has a circulation path through which argon, used as working gas, is circulated back to a combustion chamber and that uses hydrogen as fuel during operation, oxygen is supplied in such a manner that the oxygen supply ratio is higher than that used during normal operation. Thus, the entirety of hydrogen supplied into the combustion chamber reacts with oxygen and is burned. When the engine is being started, because gas is not turbulent enough, hydrogen and oxygen are likely to be mixed poorly. Therefore, when oxygen is supplied in such a manner that the ratio of oxygen supply amount to the hydrogen supply amount is higher than the theoretical ratio, even if oxygen and hydrogen are not mixed so well, the chance that hydrogen contacts oxygen is increased. As a result, combustion takes place in a more appropriate manner, which improves the engine startability. | 2010-12-02 |

The combustion chamber is stratified when the compression end is positioned within a stratified distance of the closed end. When stratified, the combustion chamber is comprised of a central combustion region, a perimeter squish region, and a transfer passage between the regions.

The exothermic chemical reaction is initiated only after at least one (typically a dry powder catalyst) goes into aqueous solution after the application of water (saline or non-saline). The catalytic solution flows out, through, and about and among water-permeable pockets in the pouch-like apparatus which contain one or more other ingredients, including the active ingredient (e.g., the Mg—Fe alloy). Thus, the catalyst and the active ingredient do not come into effective contact until a flowing aqueous saline solution carries a reactive catalytic-saline solution to the active ingredient alloy, and then mixes the inter-reactive ingredients to generate the desired heat. | 2010-12-02 |
