Apparatus for optimizing fuel/air mixing process of internal combustion engine

An apparatus for optimizing the fuel/air mixing process of an internal combustion engine, wherein the bottom surface of the cylinder head (3) is provided with a plurality of brackets (1);

• a ring (2) is fixed to the brackets;
• the ring can be an integrated ring body and can also be composed of a plurality of small segments;
• the number of the small segment ring bodies is equal to or less than the number of air valves of the internal combustion engine;
• the ring is positioned opposite to a fuel injector (4);
• the ring has the ability of continuously guiding the fuel during the fuel injection process;
• the ring is located in the area where the fuel flows in the combustion chamber and can be arranged in the liquid-phase region (5-1), a gas-liquid two-phase region (5-2) or a gas-phase region (5-3);
• and when the location of the ring interferes with the movement of the valves (6) of the internal combustion engine, part of the ring body that interferes with the movement of the valves can be removed.
