    摘要： A piston for a reciprocating piston internal combustion engine is provided with a reaction chamber (44, 144) communicating with a recessed area (42, 142) of the piston through a restricted continuous slot orifice (46, 146) that is configured to create a choked fluid flow condition between the combustion chamber (30, 130) and the reaction chamber at all engine operating speeds. Fuel is supplied to the reaction chamber and undergoes a controlled, cold frame reaction process while in intimate contact with the crown portion (54) of the piston (14). The reaction produces fuel radicals in sufficient quantity to seed subsequent fuel charges to properly condition the charge for predetermined desired ignition and combustion characteristics. The choking orifice (46, 146) ensures that outward flow of radicals from the reaction chamber is controlled to the extent that they will be maintained in the combustion chamber following an exhaust event of the combustion cycle so they will be available during a subsequent compression stroke of the piston for seeding the subsequent charge. The radical population in the subsequent charge conditions the charge to obtain dependable and predictable ignition in a compression ignition engine as well as knock free combustion at relatively lean air to fuel ratios in a spark ignited engine.

    摘要： A reciprocating piston internal combustion engine is provided with a fixed volume air chamber located next to the working face of the piston and separated from the combustion chamber solely by a circumferential gap extending between the working face of the piston and the adjacent cylinder sidewall. The gap permits continuous controlled exchange of compression shock and expansion wave energy between the combustion and air chambers during a combustion reaction of fuel and air in the combustion chamber. The air chamber extends along a peripheral length of the piston and is provided with a radially inner sidewall including a generally sloping portion that extends from the piston side edge of the gap towards the bottom area of the air chamber, the inner sidewall characterized in that it is continuous and uninterrupted over the entire length of the air chamber and in that the sloping portion of the sidewall continuously diverges away from the adjacent cylinder sidewall over its respective length. A specific form of wedge-shaped cross sectional area of the air chamber is disclosed.

    摘要： A tethered naval mine adapted automatically to maintain a predetermined depth below the surface of a body of water despite changes in water level. Provision is made for safeguarding operating personnel prior to deployment of the mine and to cause self-destruction thereof upon expiration of a predetermined period. The mine arrangement is such as to effect detonation either upon contact with a craft or by disturbances produced by the wake of a vessel or by mine-sweeping apparatus.

    摘要： A diesel cycle, direct injected internal combustion engine is provided with a piston recess or bowl into which fuel is injected each combustion cycle. One or more reaction chambers adjacent the piston recess are in communication with the recess through an array of discrete orifices located along the side wall of the recess. Partial reaction of fuel and air in the reaction chambers each combustion cycle produces radicals including intermediate species for seeding a fuel air mixture of a following combustion cycle through a delayed discharge of radicals from the reaction chamber into the piston recess. The discrete orifices are arranged in a specific array that ensures a desired chaotic flow in the reaction chambers and maximum interaction between radicals discharged from the reaction chamber and the soot cloud formed in the combustion chamber upon ignition of the fuel air mixture in the piston recess. Two or more rows of orifices may be used with at least one row located centrally along the reaction chamber cross-section and at least a second row intersecting the first row and arranged diagonally or vertically relative to the first row. The diagonal or vertical row includes orifices that intersect the reaction chamber tangentially at upper and lower regions thereof. The disclosed apparatus results in an exhaust effluent having markedly reduced smoke and particulate components.
