  • Patent number: 7156069
    Abstract: A combustion chamber opening toward a cylinder head is provided on a top surface of a piston, and this combustion chamber comprises a first volume having an inclined surface and a second volume further recessed from the first volume toward a pin boss. Fuel spray F from a fuel injection nozzle is injected toward an inner peripheral wall section of the second volume in a former stage of fuel injection and toward the inclined surface of the first volume in a later stage of fuel injection, and the percentage of the fuel injection period in the former stage against the total fuel injection period is set to the range from 40% to 70%.

  • Patent number: 5074265
    Abstract: A coaxial rotary valve mechanism for an internal combustion engine that incorporates two coaxial, cylinder shaped rotors in the cylinder head, rotating with speed ratio of 2:1 so that ports in their surfaces align at the appropriate segments of the operating cycle to function as air intake valves. The outer rotor further comprises a recess on its surface which has plurality of functions. During the compression stroke said recess forms a pre-combustion chamber between said rotor and the cylinder head, and during the exhaust stroke brings the cylinder into the open registry with the exhaust port allowing combustion gases to be exhausted. During the compression stroke the liquid fuel is injected into the pre-combustion chamber containing exhaust gases, while said pre-combustion chamber is in closed registry with the cylinder.

  • Patent number: 4532899
    Abstract: A fuel injection and precombustion chamber arrangement for internal combustion engines comprising a pair of concentric poppet valves. The outermost valve is arranged to open and close the precombustion chamber to the internal combustion engine cylinder. The innermost valve is arranged to open and close a chamber, formed in the outermost valve body, to the cylinder and to place a fuel-filled annular groove on the spool of the innermost valve in communication with the precombustion chamber and the chamber in the outermost valve such as to mix air flowing through the chamber of the outermost valve from the cylinder fuel and inject into the precombustion chamber the fuel contained in the annular groove in an atomized state.
